HUMAN EVALUTION

Human evolution, or anthropogenesis, is the part of biological evolution concerning the emergence of Homo sapiens as a distinct species from other hominins, great apes and placental mammals. It is the subject of a broad scientific inquiry that seeks to understand and describe how this change occurred. The study of human evolution encompasses many scientific disciplines, most notably physical anthropology, primatology, archaeology, linguistics and genetics.

The term "human", in the context of human evolution, refers to the genus Homo, but studies of human evolution usually include other hominins, such as the Australopithecines. The Homo genus diverged from the Australopithecines about 2 million years ago in Africa. Scientists have estimated that humans branched off from their common ancestor with chimpanzees—the only other living homininis—about 5–7 million years ago. Several species of Homo evolved that are now extinct. These include Homo erectus, which inhabited Asia, and Homo neanderthalensis, which inhabited Europe.

Archaic Homo sapiens evolved between 400,000 and 250,000 years ago. The dominant view among scientists is the recent African origin of modern humans (RAO) that H. sapiens evolved in Africa and spread across the globe, replacing populations of H. erectus and H. neanderthalensis. Scientists supporting the alternative hypothesis on the multiregional evolution (ME) view modern humans as having evolved as a single, widespread population from existing Homo species, particularly H. erectus. The fossil evidence is insufficient to resolve this vigorous debate,. Studies of haplogroups in Y-chromosomal DNA and mitochondrial DNA have largely supported a recent African origin, while some researchers argue that evidence from nuclear genes supports a multiregional origin.

     History of ideas about human evolution

The word homo, the name of the biological genus to which humans belong, is Latin for "human". It was chosen originally by Carolus Linnaeus in his classification system. The word "human" is from the Latin humanus, the adjectival form of homo. The Latin "homo" derives from the Indo-European root, dhghem, or "earth".

Carolus Linnaeus and other scientists of his time also considered the great apes to be the closest relatives of human beings due to morphological and anatomical similarities. The possibility of linking humans with earlier apes by descent only became clear after 1859 with the publication of Charles Darwin's On the Origin of Species. This argued for the idea of the evolution of new species from earlier ones. Darwin's book did not address the question of human evolution, saying only that "Light will be thrown on the origin of man and his history".

The first debates about the nature of human evolution arose between Thomas Huxley and Richard Owen. Huxley argued for human evolution from apes by illustrating many of the similarities and differences between humans and apes and did so particularly in his 1863 book Evidence as to Man's Place in Nature. However, many of Darwin's early supporters (such as Alfred Russel Wallace and Charles Lyell) did not agree that the origin of the mental capacities and the moral sensibilities of humans could be explained by natural selection. Darwin applied the theory of evolution and sexual selection to humans when he published The Descent of Man in 1871.

A major problem was the lack of fossil intermediaries. It was only in the 1920s that such fossils were discovered in Africa. In 1925, Raymond Dart described Australopithecus africanus. The type specimen was the Taung Child, an Australopithecine infant discovered in a cave. The child's remains were a remarkably well-preserved tiny skull and an endocranial cast of the individual's brain. Although the brain was small (410 cm³), its shape was rounded, unlike that of chimpanzees and gorillas, and more like a modern human brain. Also, the specimen showed short canine teeth, and the position of the foramen magnum was evidence of bipedal locomotion. All of these traits convinced Dart that the Taung baby was a bipedal human ancestor, a transitional form between apes and humans.

The classification of humans and their relatives has changed considerably over time. The Australopithecines are now thought to be ancestors of the genus Homo, the group to which modern humans belong. Both Australopithecines and Homo sapiens are part of the tribe Hominini. Recent data suggests Australopithecines were a diverse group and that A. africanus may not be a direct ancestor of modern humans. Reclassification of Australopithecines that originally were split into either gracile or robust varieties has put the latter into a family of its own, Paranthropus. Taxonomists place humans, Australopithecines and related species in the same family as other great apes, in the Hominidae.

The validity of evolution and the origins of humanity have often been a subject of great political and religious controversy within the non-scientific community, as characterized by the Creation-evolution controversy, though within the legitimate scientific community, the evolutionary origin of humanity is widely accepted. Speculation about the future evolution of humans is often explored in science fiction and in theories of transhumanism.    

Before Homo

Evolution of apes

The evolutionary history of the primates can be traced back 65 million years, as one of the oldest of all surviving placental mammal groups. The oldest known primates come from North America, but they were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and Eocene.

With the beginning of modern climates, marked by the formation of the first Antarctic ice in the early Oligocene around 30 million years ago, primates went extinct everywhere but Africa and southern Asia. A primate from this time was Notharctus. Fossil evidence found in Germany in the 1980s was determined to be about 16.5 million years old, some 1.5 million years older than similar species from East Africa. It suggests that the primate lineage of the great apes first appeared in Eurasia and not Africa.

The early ancestors of the hominids (the family of great apes and humans) probably migrated to Eurasia from Africa about 17 million years ago, just before these two continents were cut off from each other by an expansion of the Mediterranean Sea. Begun[6] says that these primates flourished in Eurasia and that the lineage leading to the African apes and humans— including Dryopithecus—migrated south from Europe or Western Asia into Africa. The surviving tropical population, which is seen most completely in the upper Eocene and lowermost Oligocene fossil beds of the Fayum depression southwest of Cairo, gave rise to all living primates—lemurs of Madagascar, lorises of Southeast Asia, galagos or "bush babies" of Africa, and the anthropoids; platyrrhines or New World monkeys, and catarrhines or Old World monkeys and the great apes and humans.

The earliest known catarrhine is Kamoyapithecus from uppermost Oligocene at Eragaleit in the northern Kenya Rift Valley, dated to 24 million years ago. Its ancestry is generally thought to be species related to Aegyptopithecus, Propliopithecus, and Parapithecus from the Fayum, at around 35 million years ago. There are no fossils from the intervening 11 million years.

In the early Miocene, after 22 million years ago, the many kinds of arboreally-adapted primitive catarrhines from East Africa suggest a long history of prior diversification. Fossils at 20 million years ago include fragments attributed to Victoriapithecus, the earliest Old World Monkey. Among the genera thought to be in the ape lineage leading up to 13 million years ago are Proconsul, Rangwapithecus, Dendropithecus, Limnopithecus, Nacholapithecus, Equatorius, Nyanzapithecus, Afropithecus, Heliopithecus, and Kenyapithecus, all from East Africa. The presence of other generalized non-cercopithecids of middle Miocene age from sites far distant—Otavipithecus from cave deposits in Namibia, and Pierolapithecus and Dryopithecus from France, Spain and Austria—is evidence of a wide diversity of forms across Africa and the Mediterranean basin during the relatively warm and equable climatic regimes of the early and middle Miocene. The youngest of the Miocene hominoids, Oreopithecus, is from 9 million year old coal beds in Italy.

Molecular evidence indicates that the lineage of gibbons (family Hylobatidae) became distinct from Great Apes between 18 and 12 million years ago, and that of orangutans (subfamily Ponginae) became distinct from the other Great Apes at about 12 million years; there are no fossils that clearly document the ancestry of gibbons, which may have originated in a so-far-unknown South East Asian hominoid population, but fossil proto-orangutans may be represented by Ramapithecus from India and Griphopithecus from Turkey, dated to around 10 million years ago.

Divergence of the human lineage from other Great Apes

Species close to the last common ancestor of gorillas, chimpanzees and humans may be represented by Nakalipithecus fossils found in Kenya and Ouranopithecus found in Greece. Molecular evidence suggests that between 8 and 4 million years ago, first the gorillas, and then the chimpanzees (genus Pan) split off from the line leading to the humans; human DNA is approximately 98.4% identical to that of chimpanzees when comparing single nucleotide polymorphisms (see Human evolutionary genetics). The fossil record of gorillas and chimpanzees is quite limited. Both poor preservation (rain forest soils tend to be acidic and dissolve bone) and sampling bias probably contribute to this problem.

Other hominines likely adapted to the drier environments outside the equatorial belt, along with antelopes, hyenas, dogs, pigs, elephants, and horses. The equatorial belt contracted after about 8 million years ago. Fossils of these hominans - the species in the human lineage following divergence from the chimpanzees - are relatively well known. The earliest are Sahelanthropus tchadensis (7 Ma) and Orrorin tugenensis (6 Ma), followed by:
Ardipithecus (5.5–4.4 Ma), with species Ar. kadabba and Ar. ramidus;
Australopithecus (4–2 Ma), with species Au. anamensis, Au. afarensis, Au. africanus, Au. bahrelghazali, and Au. garhi;
Kenyanthropus (3–2.7 Ma), with species Kenyanthropus platyops
Paranthropus (3–1.2 Ma), with species P. aethiopicus, P. boisei, and P. robustus;
Homo (2 Ma–present), with species Homo habilis, Homo rudolfensis, Homo ergaster, Homo georgicus, Homo antecessor, Homo cepranensis, Homo erectus, Homo heidelbergensis, Homo rhodesiensis, Homo neanderthalensis, Homo sapiens idaltu, Archaic Homo sapiens, Homo floresiensis

Genus Homo

Homo sapiens is the only non-extinct species of its genus, Homo. There were other Homo species, all of which are now extinct. While some of these other species might have been ancestors of H. sapiens, many were likely our "cousins", having speciated away from our ancestral line.[7] There is not yet a consensus as to which of these groups should count as separate species and which as subspecies. In some cases this is due to the paucity of fossils, in other cases it is due to the slight differences used to classify species in the Homo genus. The Sahara pump theory provides an explanation of the early variation in the genus Homo.

Based on archaeological and paleontological evidence, it has been possible to infer the ancient dietary practices of various Homo species and to study the role of diet in physical and behavioral evolution within Homo.

Homo habilis

H. habilis lived from about 2.4 to 1.4 Ma. H. habilis, the first species of the genus Homo, evolved in South and East Africa in the late Pliocene or early Pleistocene, 2.5–2 Ma, when it diverged from the Australopithecines. H. habilis had smaller molars and larger brains than the Australopithecines, and made tools from stone and perhaps animal bones. One of the first known hominids, it was nicknamed 'handy man' by its discoverer, Louis Leakey due to its association with stone tools. Some scientists have proposed moving this species out of Homo and into Australopithecus due to the morphology of its skeleton being more adapted to living on trees rather than to moving on two legs like H. sapiens.

Homo rudolfensis and Homo georgicus

These are proposed species names for fossils from about 1.9–1.6 Ma, the relation of which with H. habilis is not yet clear.
H. rudolfensis refers to a single, incomplete skull from Kenya. Scientists have suggested that this was another H. habilis, but this has not been confirmed.[14]
H. georgicus, from Georgia, may be an intermediate form between H. habilis and H. erectus, or a sub-species of H. erectus.

Homo ergaster and Homo erectus
 
One current view of the temporal and geographical distribution of hominid populations. Other interpretations differ mainly in the taxonomy and geographical distribution of hominid species.

The first fossils of Homo erectus were discovered by Dutch physician Eugene Dubois in 1891 on the Indonesian island of Java. He originally gave the material the name Pithecanthropus erectus based on its morphology that he considered to be intermediate between that of humans and apes.[17] H. erectus lived from about 1.8 Ma to 70,000 years ago. Often the early phase, from 1.8 to 1.25 Ma, is considered to be a separate species, H. ergaster, or it is seen as a subspecies of H. erectus, Homo erectus ergaster.

In the early Pleistocene, 1.5–1 Ma, in Africa, Asia, and Europe, some populations of Homo habilis are thought to have evolved larger brains and made more elaborate stone tools; these differences and others are sufficient for anthropologists to classify them as a new species, H. erectus. In addition H. erectus was the first human ancestor to walk truly upright.[18] This was made possible by the evolution of locking knees and a different location of the foramen magnum (the hole in the skull where the spine enters). They may have used fire to cook their meat.

A famous example of Homo erectus is Peking Man; others were found in Asia (notably in Indonesia), Africa, and Europe. Many paleoanthropologists now use the term Homo ergaster for the non-Asian forms of this group, and reserving H. erectus only for those fossils found in the Asian region and meeting certain skeletal and dental requirements which differ slightly from H. ergaster.

Homo cepranensis and Homo antecessor

These are proposed as species that may be intermediate between H. erectus and H. heidelbergensis.
H. antecessor is known from fossils from Spain and England that are dated 1.2 Ma–500 ka.
H. cepranensis refers to a single skull cap from Italy, estimated to be about 800,000 years old.

Homo heidelbergensis

H. heidelbergensis (Heidelberg Man) lived from about 800,000 to about 300,000 years ago. Also proposed as Homo sapiens heidelbergensis or Homo sapiens paleohungaricus.

Homo rhodesiensis, and the Gawis cranium

H. rhodesiensis, estimated to be 300,000–125,000 years old. Most current experts believe Rhodesian Man to be within the group of Homo heidelbergensis though other designations such as Archaic Homo sapiens and Homo sapiens rhodesiensis have also been proposed.

In February 2006 a fossil, the Gawis cranium, was found which might possibly be a species intermediate between H. erectus and H. sapiens or one of many evolutionary dead ends. The skull from Gawis, Ethiopia, is believed to be 500,000–250,000 years old. Only summary details are known, and no peer reviewed studies have been released by the finding team. Gawis man's facial features suggest its being either an intermediate species or an example of a "Bodo man" female.

Homo neanderthalensis

H. neanderthalensis lived from about 250,000 to as recent as 30,000 years ago. Also proposed as Homo sapiens neanderthalensis: there is ongoing debate over whether the 'Neanderthal Man' was a separate species, Homo neanderthalensis, or a subspecies of H. sapiens[24] While the debate remains unsettled, evidence from sequencing mitochondrial DNA indicates that no significant gene flow occurred between H. neanderthalensis and H. sapiens, and, therefore, the two were separate species that shared a common ancestor about 660,000 years ago.[25][26] In 1997, Mark Stoneking stated: "These results [based on mitochondrial DNA extracted from Neanderthal bone] indicate that Neanderthals did not contribute mitochondrial DNA to modern humans… Neanderthals are not our ancestors." Subsequent investigation of a second source of Neanderthal DNA supported these findings.[27] However, supporters of the multiregional hypothesis point to recent studies indicating non-African nuclear DNA heritage dating to one Ma,[28] although the reliability of these studies has been questioned.Competition from Homo sapiens probably contributed to Neanderthal extinction.


Homo sapiens

H. sapiens ("sapiens" is Latin for wise or intelligent) has lived from about 250,000 years ago to the present. Between 400,000 years ago and the second interglacial period in the Middle Pleistocene, around 250,000 years ago, the trend in skull expansion and the elaboration of stone tool technologies developed, providing evidence for a transition from H. erectus to H. sapiens. The direct evidence suggests there was a migration of H. erectus out of Africa, then a further speciation of H. sapiens from H. erectus in Africa. A subsequent migration within and out of Africa eventually replaced the earlier dispersed H. erectus. This migration and origin theory is usually referred to as the recent single origin or Out of Africa theory. Current evidence does not preclude some multiregional evolution or some admixture of the migrant H. sapiens with existing Homo populations. This is a hotly debated area of paleoanthropology.

Current research has established that human beings are genetically highly homogenous; that is, the DNA of individuals is more alike than usual for most species, which may have resulted from their relatively recent evolution or the Toba catastrophe.[32][33][34] Distinctive genetic characteristics have arisen, however, primarily as the result of small groups of people moving into new environmental circumstances. These adapted traits are a very small component of the Homo sapiens genome, but include various characteristics such as skin color and nose form, in addition to internal characteristics such as the ability to breathe more efficiently in high altitudes.

H. sapiens idaltu, from Ethiopia, is a possible extinct sub-species who lived from about 160,000 years ago. It is the oldest known anatomically modern human.

Homo floresiensis

H. floresiensis, which lived from approximately 100,000 to 12,000 before present, has been nicknamed hobbit for its small size, possibly a result of insular dwarfism.[35] H. floresiensis is intriguing both for its size and its age, being a concrete example of a recent species of the genus Homo that exhibits derived traits not shared with modern humans. In other words, H. floresiensis share a common ancestor with modern humans, but split from the modern human lineage and followed a distinct evolutionary path. The main find was a skeleton believed to be a woman of about 30 years of age. Found in 2003 it has been dated to approximately 18,000 years old. The living woman was estimated to be one meter in height, with a brain volume of just 380 cm3 (considered small for a chimpanzee and less than a third of the H. sapiens average of 1400 cm3).

However, there is an ongoing debate over whether H. floresiensis is indeed a separate species.[36] Some scientists presently believe that H. floresiensis was a modern H. sapiens suffering from pathological dwarfism. This hypothesis is supported in part, because some modern humans who live on Flores, the island where the skeleton was found, are pygmies. This coupled with pathological dwarfism could indeed create a hobbit-like human. The other major attack on H. floresiensis is that it was found with tools only associated with H. sapiens.

Use of tools

Using tools has been interpreted as a sign of intelligence, and it has been theorized that tool use may have stimulated certain aspects of human evolution—most notably the continued expansion of the human brain. Paleontology has yet to explain the expansion of this organ over millions of years despite being extremely demanding in terms of energy consumption. The brain of a modern human consumes about 20 watts (400 kilocalories per day), which is one fifth of the energy consumption of a human body. Increased tool use would allow hunting for energy-rich meat products, and would enable processing more energy-rich plant products. Researchers have suggested that early hominids were thus under evolutionary pressure to increase their capacity to create and use tools.[38]

Precisely when early humans started to use tools is difficult to determine, because the more primitive these tools are (for example, sharp-edged stones) the more difficult it is to decide whether they are natural objects or human artifacts. There is some evidence that the australopithecines (4 Ma) may have used broken bones as tools, but this is debated.

It should be noted that many species make and use tools, but it is the human species that dominates the areas of making and using more complex tools. A good question is, what species made and used the first tools? The oldest known tools are the "Oldowan stone tools" from Ethiopia. It was discovered that these tools are from 2.5 to 2.6 million years old, which predates the earliest known "Homo" species. There is no known evidence that any "Homo" specimens appeared by 2.5 Ma. A Homo fossil was found near some Oldowan tools, and its age was noted at 2.3 million years old, suggesting that maybe the Homo species did indeed create and use these tools. It is surely possible, but not solid evidence. Bernard Wood noted that "Paranthropus" coexisted with the early Homo species in the area of the "Oldowan Industrial Complex" over roughly the same span of time. Although there is no direct evidence that points to Paranthropus as the tool makers, their anatomy lends to indirect evidence of their capabilities in this area. Most paleoanthropologists agree that the early "Homo" species were indeed responsible for most of the Oldowan tools found. They argue that when most of the Oldowan tools were found in association with human fossils, Homo was always present, but Paranthropus was not.[39]

In 1994, Randall Susman used the anatomy of opposable thumbs as the basis for his argument that both the Homo and Paranthropus species were toolmakers. He compared bones and muscles of human and chimpanzee thumbs, finding that humans have 3 muscles that chimps lack. Humans also have thicker metacarpals with broader heads, making the human hand more successful at precision grasping than the chimpanzee hand. Susman defended that modern anatomy of the human thumb is an evolutionary response to the requirements associated with making and handling tools and that both species were indeed toolmakers.[39]

Stone tools

Stone tools are first attested around 2.6 Ma, when H. habilis in Eastern Africa used so-called pebble tools, choppers made out of round pebbles that had been split by simple strikes.[40] This marks the beginning of the Paleolithic, or Old Stone Age; its end is taken to be the end of the last Ice Age, around 10,000 years ago. The Paleolithic is subdivided into the Lower Paleolithic (Early Stone Age, ending around 350,000–300,000 years ago), the Middle Paleolithic (Middle Stone Age, until 50,000–30,000 years ago), and the Upper Paleolithic.

The period from 700,000–300,000 years ago is also known as the Acheulean, when H. ergaster (or erectus) made large stone hand-axes out of flint and quartzite, at first quite rough (Early Acheulian), later "retouched" by additional, more subtle strikes at the sides of the flakes. After 350,000 BP (Before Present) the more refined so-called Levallois technique was developed. It consisted of a series of consecutive strikes, by which scrapers, slicers ("racloirs"), needles, and flattened needles were made.[40] Finally, after about 50,000 BP, ever more refined and specialized flint tools were made by the Neanderthals and the immigrant Cro-Magnons (knives, blades, skimmers). In this period they also started to make tools out of bone.

Modern humans and the "Great Leap Forward" debate

Until about 50,000–40,000 years ago the use of stone tools seems to have progressed stepwise. Each phase (H. habilis, H. ergaster, H. neanderthalensis) started at a higher level than the previous one, but once that phase started further development was slow. These Homo species were culturally conservative, but after 50,000 BP modern human culture started to change at a much greater speed. Jared Diamond, author of The Third Chimpanzee, and other anthropologists characterize this as a "Great Leap Forward." Modern humans started burying their dead, making clothing out of hides, developing sophisticated hunting techniques (such as using trapping pits or driving animals off cliffs), and engaging in cave painting.[41] As human culture advanced, different populations of humans introduced novelty to existing technologies: artifacts such as fish hooks, buttons and bone needles show signs of variation among different populations of humans, something that had not been seen in human cultures prior to 50,000 BP. Typically, H. neanderthalensis populations do not vary in their technologies.

Modern human behavior includes four apects: abstract thinking (concepts free from specific examples), planning (taking steps to achieve a further goal), innovation (finding new solutions), and symbolic behaviour (such as images and rituals). Among concrete examples of modern human behavior, anthropologists include specialization of tools, use of jewellery and images (such as cave drawings), organization of living space, rituals (for example, burials with grave gifts), specialized hunting techniques, exploration of less hospitable geographical areas, and barter trade networks. Debate continues as to whether a "revolution" led to modern humans ("the big bang of human consciousness"), or whether the evolution was more gradual.[42]

Models of human evolution

Today, all humans are classified as belonging to the species Homo sapiens sapiens. However, this is not the first species of hominids: the first species of genus Homo, Homo habilis, evolved in East Africa at least 2 Ma, and members of this species populated different parts of Africa in a relatively short time. Homo erectus evolved more than 1.8 Ma, and by 1.5 Ma had spread throughout the Old World. Virtually all physical anthropologists agree that Homo sapiens evolved out of Homo erectus. Anthropologists have been divided as to whether Homo sapiens evolved as one interconnected species from H. erectus (called the Multiregional Model, or the Regional Continuity Model), or evolved only in East Africa, and then migrated out of Africa and replaced H. erectus populations throughout the Old World (called the Out of Africa Model or the Complete Replacement Model). Anthropologists continue to debate both possibilities, but most anthropologists currently favor the Out of Africa model.

Multiregional model

Advocates of the Multiregional model, primarily Milford Wolpoff and his associates, have argued that the simultaneous evolution of H. sapiens in different parts of Europe and Asia would have been possible if there was a degree of gene flow between archaic populations.[43] Similarities of morphological features between archaic European and Chinese populations and modern H. sapiens from the same regions, Wolpoff argues, support a regional continuity only possible within the Multiregional model.[44] Wolpoff and others further argue that this model is consistent with clinal patterns of phenotypic variation (Wolpoff 1993).

Out of Africa

According to the Out of Africa model, developed by Chris Stringer and Peter Andrews, modern H. sapiens evolved in Africa 200,000 years ago. Homo sapiens began migrating from Africa between 70,000 – 50,000 years ago and would eventually replace existing hominid species in Europe and Asia.[45][46] Out of Africa has gained support from research using mitochondrial DNA (mtDNA). After analysing genealogy trees constructed using 133 types of mtDNA, researchers concluded that all were descended from a woman from Africa, dubbed Mitochondrial Eve. Out of Africa is also supported by the fact that mitochondrial genetic diversity is highest among African populations.

There are differing theories on whether there was a single exodus or several. A multiple dispersal model involves the Southern Dispersal theory,[48] which has gained support in recent years from genetic, linguistic and archaeological evidence. In this theory, there was a coastal dispersal of modern humans from the Horn of Africa around 70,000 years ago. This group helped to populate Southeast Asia and Oceania, explaining the discovery of early human sites in these areas much earlier than those in the Levant. A second wave of humans dispersed across the Sinai peninsula into Asia, resulting in the bulk of human population for Eurasia. This second group possessed a more sophisticated tool technology and was less dependent on coastal food sources than the original group. Much of the evidence for the first group's expansion would have been destroyed by the rising sea levels at the end of the Holocene era.[48] The multiple dispersal model is contradicted by studies indicating that the populations of Eurasia and the populations of Southeast Asia and Oceania are all descended from the same mitochondrial DNA lineages, which support a single migration out of Africa that gave rise to all non-African populations.

Comparison of the two models

The two models differ widely. Richard Leakey summarizes the most obvious differences as follows:“ The multiregional evolution model describes an evolutionary trend throughout the Old World toward modern Homo sapiens, with little population migration and no population replacement, whereas the 'Out of Africa' model calls for the evolution of Homo sapiens in one location only, followed by extensive population migration across the Old World, resulting in the replacement of existing premodern populations. ”


The Multiregional model suggests that the fossil record should show the same regional differences in anatomical characteristics that are currently visible today. Racial differences would be deep-rooted, going back as much as two million years. In the Out of Africa model, however, the fossil record would not be expected to show continuity of anatomical characteristics over time; on the contrary, the regional characteristics of older fossils would likely be replaced globally by more modern African ones. Racial differences would be shallow-rooted, having evolved over a relatively short period of time.

Implications for the concept of race

In a 1995 article, Leonard Lieberman and Fatimah Jackson point out that the concepts of cline, population, and ethnicity, as well as humanitarian and political concerns, have led many scientists away from the notion of race; nevertheless, a recent survey showed that physical anthropologists were evenly divided as to whether race is a valid biological concept. They note that among physical anthropologists the vast majority of opposition to the race concept comes from population geneticists, so any new support for a biological concept of race would likely come from another source, namely, the study of human evolution. They therefore ask what, if any, implications the current models of human evolution may have for any biological conception of race.[50]“ The major implication for race in the multiregional evolution continuity model involves the time depth of a million or more years in which race differentiation might evolve in diverse ecological regions [...]. This must be balanced against the degree of gene flow and the transregional operation of natural selection on encephalization due to development of tools and, more broadly, culture. ”

Lieberman and Jackson identified these implications of the Out of Africa model on the race concept:“ The shallow time dimension minimizes the degree to which racial differences could have evolved [...]. [T]he mitochondrial DNA model presents a view ... minimizing race differences and avoiding racist implications. However, the model, as interpreted by Wainscoat et al. (1989:34), does describe "a major division of human populations into an African and a Eurasian group." This conclusion could best be used to emphasize the degree of biological differences, and thereby provide support for the race concept. ”

Lieberman and Jackson argued that while advocates of both the Multiregional model and the Out of Africa model use the word race and make racial assumptions, none define the term. They conclude, "Each model has implications that both magnify and minimize the differences between races. Yet each model seems to take race and races as a conceptual reality. The net result is that those anthropologists who prefer to view races as a reality are encouraged to do so." However, Lieberman and Jackson conclude that students of human evolution would be better off avoiding the word race, instead describing genetic differences in terms of populations and clinal gradations.

Moving to the savanna and the aquatic ape hypothesis

The majority of scientists believe in a model, first propounded by Raymond Dart, that the arboreal existence of early human was replaced by a move to the savannah for hunting animals, even though major adaptations occurred in human ancestors long before the savannahs existed. An alternative model of human evolution, strongly disputed by many researchers, is the aquatic ape hypothesis (AAH). This asserts that wading, swimming and diving for food exerted a strong evolutionary effect on the ancestors of the genus Homo and is in part responsible for the split between the common ancestors of humans and other great apes.

Huge Keyboard Shortcut List

What is the allure of keyboard shortcuts? Do they really save time? Why bother since my mouse is permanently attached to my hand? 

I like to use keyboard shortcuts, especially if someone is watching me, because they make me look like a pro. With just a few key strokes I can leave a mouser spinning his wheel! Whatever your motivation, here's a big list of keyboard shortcuts: 

GENERAL SHORTCUTS 
ALT- F4 - Quit a program / Shut down 
ALT-TAB - Hold down the ALT key and hit tab to cycle through open windows. 
CTL-ESCAPE - Display the Start menu 
SHIFT - TAB - tab backwards through a form 
CTRL - X - Cut 
CTRL - C - Copy 
CTRL - V - Paste 
F1 - Help menu 
CTRL - Z - Undo 
SHIFT & Restart - To restart just windows and not your whole computer, hold down the shift key when you click the OK button on the shutdown screen. Saves lots of time. (Not for XP) 
CRTL-TAB - Navigate tabs on a tabbed screen 
FILE & DESKTOP SHORTCUTS 
Hold SHIFT while inserting a CD - Prevents the CD from "autorunning" 
If an item is selected:

Select text in Location Bar Ctrl+L 
Force Reload (not from Cache) Ctrl+Shift+R 
Zoom Text Smaller Ctrl+- (minus)

 WINDOWS KEY SHORTCUTS 
The Windows key can be used in conjunction with other keys to act as a keyboard shortcut for faster access to menu commands. Now, while the Alt key tends to open program menus (ex: Alt+F opens the File menu and Alt+E opens the Edit menu) and the Ctrl key performs actual operations (ex: Ctrl+C will copy and Ctrl+V will paste), the Windows key will open various Windows tools... 
Win key + R will open the Start menu's Run box 
Win key + F will open the Start menu's Find window 
Win key + E will quickly launch Explorer 
Win key + Pause/Break will open the System Properties window 
Win key + M will Minimize all windows 
Win key + Shift + M will undo Minimize all windows 
Win key + D will switch between minimizing all open programs and showing them all 
Win key + Tab will cycle through items on the taskbar 
Win key by itself will open the Start menu 

You can also open programs or folders on your desktop by pressing the Windows key + the first letter of the program/folder/shortcut + Enter . Sounds kinda tedious, but if you're in a bind with your mouse, it can come in quite handy. 

ARROW TRICKS 
Here's a cool little arrow trick to try with word processing programs. Next time you're using your arrow keys to go from one area of a sentence to another (left and right arrows), hold down your CTRL key. Instead of moving one space at a time, you'll go one word at a time. 
If you're using the up and down arrows to go from line to line, holding down the CTRL key will make your cursor jump from paragraph to paragraph (well, from carriage return to carriage return anyway). 
One last thing, if you hold down the SHIFT key while you do this (i.e. hold down SHIFT + CTRL at the same time), you select text as you arrow along. 
I've tested this in MS Word and Wordpad, but it *should* work no matter what word processing program you use. 
HOME / END KEY FUN 
Do you ever find yourself scrolling through a huge folder ? Well, if you need to get to the beginning or the end quickly, just press Ctrl+Home . If you want to get to the end, click Ctrl+End. 
Hey, that's not all! 
This little trick works on more than just folders. If you use the Home key in a word processor, it goes to the beginning of the line you're currently working on. If you hit the END key, it should head to the end of the current line. If you pair Home & End up with the Ctrl key in a word processor, you will be whisked away to the beginning or end of the document. Again, this should work, but it depends on your word processor. 
Speedup your work by using keyboard more and mouse less.

Lohithadas - "The Tearful adieu to master storyteller"

Ambazhathil Karunakaran Lohithadas (A. K. Lohithadas) (10 May 1955 – 28 June 2009) was a prolific screenwriter, director, and producer in Malayalam cinema, known for his rich, detailed, and realistic screenplays. Thaniyavarthanam, Kireedam, Bharatham, Amaram are the possibly the masterpieces among his screenplays, while Boothakannadi, Kasthooriman, Arayannangalude Veedu standout in his directorial ventures.

* Biography

Early life

Lohithadas (or 'Lohi', he is often referred to) was born on 10 May 1955 in Chalakudy, Kerala. He showed an initial interest in short-stories, but failed to make a mark in that genre. He soon moved into Malayalam theater in 1986 when his debut script was accepted for the stage by the legendary theater personality Thoppil Bhasi. Bhasi's CPI party backed drama troupe, the highly successful 'Kerala People's Arts Club', produced the play, leading to a state award for Lohithadas.

Career

Fresh with the play's commercial and critical success, Lohithadas moved to Malayalam Cinema by writing for director Sibi Malayil. His first movie screenplay Thaniavarthanam was directed by Malayil and went on to be a success. The Sibi Malayil-Lohithadas combination would later produce several memorable Malayalam movies. His screenplay works for Sibi Malayil are Thaniyavarthanam (1987), Kireedam (1989), His Highness Abhdullah (1990), Bharatham (1990), Kamaladalam (1992), and Chenkol (1993). Sasneham (1990) and Veendum Chila Veetukaryangal (1999) for Sathyan Anthikkad and Amaram (1991) for Bharathan. He later turned into a filmmaker and made films such as Boothakannadi (1997), Karunyam (1997), Kanmadam (1998), Arayannangalude Veedu (2000), Joker (2000), Kasthooriman (2003) (which he himself produced), and Nivedyam (2007)[1]. Most of his works were critical and commercial sucess. His works were recognised from his very first venture Thaniyavarthanam which brought him Kerala State Film Award for Best Story .

Death

On June 28, 2009, in the morning he felt chest pain and uneasiness at his home at Aluva near Ernakulam and was immediately taken to the Lisy Hospital, Kaloor, Ernakulam where he was declared dead from a heart attack at 10:50

Michael Jackson - The King Of POP

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer and businessman. The seventh child of the Jackson family, he made his debut on the professional music scene in 1968 as a member of The Jackson 5. He then began a solo career in 1971 while still a member of the group and was referred to as the "King of Pop"[4] in subsequent years. Jackson's 1982 album Thriller remains the world's best-selling album of all time,[5] and four of his other solo studio albums are among the world's best-selling records: Off the Wall (1979), Bad (1987), Dangerous (1991) and History (1995).

In the early 1980s, he became a dominant figure in popular music and the first African American entertainer to amass a strong crossover following on MTV. The popularity of his music videos airing on MTV, such as "Beat It", "Billie Jean" and "Thriller" — widely credited with transforming the music video from a promotional tool into an art form — helped bring the relatively new channel to fame. Videos such as "Black or White" and "Scream" made Jackson an enduring staple on MTV in the 1990s. With stage performances and music videos, Jackson popularized a number of physically complicated dance techniques, such as the robot and the moonwalk. His distinctive musical sound and vocal style influenced many hip hop, pop and contemporary R&B artists across several generations.

One of the few artists to have been inducted into the Rock and Roll Hall of Fame twice, his other achievements include multiple Guinness World Records — including one for "Most Successful Entertainer of All Time" — 13 Grammy Awards, thirteen number one singles in his solo career, and the sale of 750 million records worldwide.[6]

Jackson donated and raised millions of dollars for beneficial causes through his foundations, charity singles, and support of 39 charities .Other aspects of his personal life, including his often changing appearances and eccentric behavior, generated significant controversy which damaged his public image. The singer had experienced health concerns since the early 1990s along with conflicting reports regarding the state of his finances since the late 1990s. Jackson married twice and brought up three children, actions which caused further controversy. Jackson was accused of child sexual abuse in 1993 but the investigation was closed due to lack of evidence and Jackson was not charged. In 2005, he was tried and acquitted of similar allegations.

On June 25, 2009, Jackson was found unconscious in his bed by his personal physician and was taken to Ronald Reagan UCLA Medical Center. He was pronounced dead at 2:26 pm PDT (21:26 UTC) on the same day. At the time of his death, he was preparing and rehearsing for This Is It, a series of 50 concerts that would have been held in London beginning July 13, 2009

NEERMATHALAM POOTHA KALAM ORMAYAYI............

Biography

She spent her childhood between Calcutta, where her father was employed as a senior officer in the Walford Transport Company that sold Bentley and Rolls Royce automobiles, and the Nalappatt ancestral home in Punnayurkulam, south Malabar. region.

Like her mother, Kamala Das also excelled in writing. Her love of poetry began at an early age through the influence of her great uncle, Nalappatt Narayana Menon, a prominent writer. However, she did not start writing professionally until after she married and became a mother. When Kamala wished to begin writing, her husband supported her decision to augment the family's income. She would often wait until nightfall after her family had gone to sleep and would write until morning:"There was only the kitchen table where I would cut vegetables, and after all the plates and things were cleared, I would sit there and start typing".^{[citation needed]} This rigorous schedule took its toll upon her health. ^[3]

She was noted for her many Malayalam short stories as well as many poems written in English. Das was also a syndicated columnist. She once claimed that "poetry does not sell in this country [India]", but her forthright columns, which sounded off on everything from women's issues and child care to politics, were popular.

Her eldest son, M D Nalapat, is married to a princess from the Travancore Royal House. He holds the UNESCO Peace Chair and Professor of geopolitics at the Manipal Academy of Higher Education. He was formerly a resident editor of theTimes of India.

On 31 May 2009, aged 75, she died at a hospital in Pune. Her body was flown to her home state of Kerala. Thousands lined the route of the funeral procession from Kochi to Trivandrum, throwing flowers on the hearse. Her funeral, at PalayamMosque in central Thiruvanathapuram, saw an unprecedented coming together of all faiths on the welcoming grounds of the Mosque to honour Kamala. She was buried in a grove on the Mosque grounds. Two trees were planted either side of the grave by her youngest son.^[4][5]

[edit]

Writings

[edit]

English

Das' first book, Summer In Calcutta was a promising start. She wrote chiefly of love, its betrayal, and the consequent anguish. Ms. Das abandoned the certainties offered by an archaic, and somewhat sterile, aestheticism for an independence of mind and body at a time when Indian women poets were still expected to write about fantasies of eternal, bloodless, unrequited love.^{[citation needed]}

At the age of 42, she published her autobiography, My Story, which was later translated into many foreign languages.^{[citation needed]}

[edit]

Malayalam

Kamala Das wrote about a range of topics, often disparate, from the story of poor old servant (Punnayoorkulam) or about the sexual disposition of upper middle class women living near a metropolitan city or in the middle of the ghetto. Some of her better-known stories include Pakshiyude Manam, Neypayasam, Thanuppu, and Chandana Marangal. She wrote a few novels , among which Neermathalam Pootha Kalam, which was received favourably by the reading public as well as the critics, stands out.

[edit]

Awards and other recognitions

Kamala Das has received many awards for her literary contribution. Some of them are

• Asian Poetry Prize
• Kent Award for English Writing from Asian Countries
• Asan World Prize
• Ezhuthachan Award
• Sahitya Academy Award
• Vayalar Award
• Kerala Sahitya Academy Award
• Muttathu Varkey Award^[6]

She travelled extensively to read poetry to Germany's Essen, Bonn and Duisburg universities, Adelaide Writer's Festival (Adelaide, Australia), Frankfurt Book Fair, University of Kingston, Jamaica, Singapore, and South Bank Festival (London),Concordia University (Montreal, Canada), Columbia University (New York), Qatar, Dubai, Sharjah, Abu Dhabi, etc. Her works are available in French, Spanish, Russian, German and Japanese.

She has also held positions as Vice chairperson in Kerala Sahitya Academy, chairperson in Kerala forestry Board, President of the Kerala Children's Film Society, editor of Poet magazine^[7] and Poetry editor of Illustrated Weekly of India.

[edit]

Conversion to Islam

Born in a conservative Hindu Nair (Nallappattu) family having Royal anscestry,^{[citation needed]} she embraced Islam in 1999 at the age of 65 and assumed the name Kamala Suraiyya. Her conversion was somewhat controversial, in among other social and literary circles.

[edit]

Politics

Though never politically active before, she launched a national political party, Lok Seva Party, aiming asylum to orphaned mothers and promotion of secularism. In 1984 she unsuccessfully contested in the Indian Parliament elections. ^[8]

Kamala Suraiyya (Malayalam: കമലാ സുരയ്യ) aka Madhavikutty (Malayalam: മാധവിക്കുട്ടി) (31 March 1934 – 31 May 2009) was an Indian writer who wrote in English as well asMalayalam, her native language. Her popularity in Kerala is based chiefly on her short stories and autobiography.

Born as Kamala Das (Malayalam: കമല ദാസ്) in Punnayurkulam Thrissur District in the state of Kerala, she was the daughter of V. M. Nair, a former managing editor of the widely-circulated Malayalam daily Mathrubhumi, and Nalappatt Balamani Amma, a renowned Malayali poetess.

Das openly and honestly discussed and wrote about the sexual desires of Indian women, which made her an iconoclast of her generation.^[1] On 31 May 2009, aged 75, she died at a hospital inPune.^[2]
