Out of africa or multiregional theory

The process of recombination in nuclear DNA except the Y chromosome mixes sections of DNA from the mother and the father creating a garbled genetic history. His results were very interesting. Africans display higher genetic variation than other populations, supporting the idea that they were the first modern humans.

What is interesting is that they found similar morphologic features on Lucy as well as on another australopithecine. Some have suggested that both Australopithecus africanus and robustus were simply an evolutionary dead end - not ancestral to man.

Furthermore, genetic variation between populations of chimpanzees is enormously greater than differences between European, Asian and African human populations. Despite this fact, Johanson continues to be a strong believer that A.

Multiregional origin of modern humans

He used a computerized tomography scanner CT-scanner to do this. A year later, thirteen similar skeletons were found. As it turns out, the canals of Australopithecus africanus and robustus are most similar to the great apes - not modern humans.

Gene Expression

Although not as far forward as in man, this more forward position is felt to indicate a more upright posture for the Australopithecines. So successful was this cultural adaptation that until roughly 11, years ago, hominids worldwide were subsisting essentially as hunter-gatherers.

Consider also that perfectly formed human footprints have been found in solidified volcanic ash dating at around "3. Spoor and his associates concluded that this finding was consistent with the idea that these creatures were at least partly arboreal and that they "did not walk habitually upright," but Spoor still believed them to be partly bipedal as well.

Around 30, years ago humans were anatomically and behaviorally similar throughout the world. L3 is about 84, years old and haplogroup M and N are about 63, years old.

Archaeological evidence Very interestingly, while Neanderthals and early Homo sapiens were distinguished from one another by a suite of obvious anatomical features, archaeologically they were very similar.

Human genetic variation and Human genetic clustering A study of African, European and Asian populations, found greater genetic diversity among Africans than among Eurasians, and that genetic diversity among Eurasians is largely a subset of that among Africans, supporting the out of Africa model.

Secondly, and more importantly, acceptance of this specimen as a hybrid would suggest that Neanderthal traits had been retained for some 6, to 10, years after Neanderthals went extinct, which is highly unlikely. The footprints have a well shaped modern heel, strong arches, and a good ball at the base of the great toe.

Furthermore, genetic variation between populations of chimpanzees is enormously greater than differences between European, Asian and African human populations. A phylogenetic analysis of domesticated cattle from around the world has indicated that they arose originally in the Middle East. The name of the third river is Tigris; it flows east of Assyria.

Spoor and his associates concluded that this finding was consistent with the idea that these creatures were at least partly arboreal and that they "did not walk habitually upright.

Human genetic variation and Human genetic clustering A study of African, European and Asian populations, found greater genetic diversity among Africans than among Eurasians, and that genetic diversity among Eurasians is largely a subset of that among Africans, supporting the out of Africa model.

It seems like the more is learned about Australopithecus, the more apelike and less like a "missing link" they appear.

So, depending on what part of the body one concentrates on, one might be able to find evidence for just about any theory of locomotion that one wishes to find. Again, with fully modern humans on the scene, it is not necessary to have Neanderthals evolve into modern humans, further bolstering the view that humans replaced Neanderthals.

Analysis of mtDNA by Rogers and Harpending12 supports the view that a small population of Homo sapiens, numbering perhaps only 10, to 50, people, left Africa somewhere between 50, andyears ago.

This aspect of the discovery has been particularly significant to indigenous Australians, since it indicates that certain cultural traditions have existed on the Australian continent for much longer than previously thought.

Mitochondrial DNA Clarifies Human Evolution

His books include Lucy: For example, Soffer11 suggests that changes in social relations, such as development of the nuclear family, played a key role in bringing about the transformation. The authors of one study admitted that Middle Eastern population genetics was not just simple gene flow, saying, "The Middle Eastern populations may have experienced both continuous gene flow and shared ancestry with the rest of Eurasia.

The major neurological and cultural innovations that characterized the appearance of fully modern humans has proven to be remarkably successful, culminating in our dominance of the planet at the expense of all earlier hominid populations.

The modern-human-like labyrinth of SK is consistent with the attribution to H. These footprints show no evidence of the curved tree-climbing bones of Lucy or of the ape-like toes of A.

Genetic evidence Investigation of the patterns of genetic variation in modern human populations supports the view that the origin of Homo sapiens is the result of a recent event that is consistent with the Out of Africa Model.

Phylogenetically, the unique labyrinth of Stw 53 represents an unlikely intermediate between the morphologies seen in the australopithecines and H.This is a perfect example of how a dark skinned black person and white person can have a child who is very light-skinned with freckles and light/red hair.

Famous People tested, results showing YDNA Haplogroup I1-M include: [1]Birger JARL aka Birger MAGNUSSON [c. – 21 October ] [updated Dec ] Birger is no longer thought to be Haplogroup-I1, to be confirmed].

Introduction Taking isolated similarities by themselves, the theory of evolution appears to be quite reasonable to a point. However, it seems that too much weight has been placed on similarities without questioning the differences.
