The Turkana Boy

I notice only small similarties with modern human populations and previous hominids. Chinese people and other orientals have high prominent cheek bones and small eye orbits just like Peking man. However in Asia there is a variation of Homo erectus characteristics.

In the Island of Java, Saringan 17 is far more robust than Peking man and it's eye orbits and cheeck are much larger. What has particularly interested the multiregionalists is that in Eastern Asia there is acountinueing trend from Homo erectus, archaic H. sapiens and modern humans. No other continent demonstrates such a gradual evolution from H. erectus to H. sapiens like Asia. This was what origionally promted scientists to think that modern humans arose in Asia. However as we all know it is much simpler to trace our ancient genetic past in Africa by mitochondria

Modern African populations have variation among themselves but many are tall and athletic like the Masaai of Kenya. Coincidently Homo ergaster's "Turkana Boy" also had a tall ethlitic body like modern Africans from the East. Sure Turkana boy had several distinctions closer to H. erectus from China, but this 9 to 12 year old did not have the ability for complex language because it's thoratic vertibrae was narrorer than modern humans. Turkana boy from 1.6 million years ago had the brain size of a 1 year old modern baby. All humans in all geographical areas in the world have craniums with similarities of Cro magnon.

Turkana boy's kin were the first groups of hominids to gradually change from the more apelike H. habilis and Australopithecines. The Australopithecine skeleton of Lucy demonstrated in a model simulation to have walked like an Orangutan, bipedal but not quit like modern humans. The pelivic on Turkana boy however was more narrow than in present day humans meaning that they were able to run longer distances than us.

Homo ergaster and it's close cousin Homo erectus were more robust than modern humans. They lived more physically demanding lives, it is likely that they were smooth-skinned and tall. In Africa or Asia as well Homo erectus may have had dark skin pigmintation as a sun protection against the Sun's deadly UV rays. All these adaptations in the physical body and along with sets of Acheulan stone tools made them the most succesful hominids of the past. Migrational routes 1.9 and 1 million years ago could not be made possible if it were not for a tight bond within each group. Since these hominids were more well adapted to their environments than the previous furry apemen, they had the ability to hunt small or larger creatures.

Some have claimed that fire was discovered less than 500,000 years ago. Perhapes they first learned to control fire after lightning struck a tree cousing it to ignite. Later on humans learned to produce fire by striking flint, later by rubbing piecesof wood like in Quest for fire.

Traits such as large browridges and slightly protruding faces still exist among a few populations to day. Essentially all skulls are similar to Cro magnons round cranium. Not that I support multiregionalism but I do have an open mind about the evolution of modern humans. It seems that because so many people are mixing today it becomes harder to seperate certain variants of modern humans.

Australoid peoples as well as few arcahic Europeans still share large brow ridges. Pretty cool!! 8) I wish I had archaic features, I have only a few. I'm a hairy guy,lol.

I find such features as not only cool, but a sign of originality....

The variations between different "races" in skeletal structure is less than the variation within groups. So exactly what is it you are trying to say?

The variation between our own species does not differ enough to conclude that they evolved from different groups (lineages). If you've studied the post cranial details on Neanderthals and modern H. sapiens you'll end up with an obvious dimorphism (speaking in comparisons with Cro-magnon) I assume Cro-Magnons represent the earliest ancestral lineage towards modern stocks in Europe or perhaps a link between Africans as well. As for Homo erectus there is too much of a variation to decide on which belongs where in the human ancestral tree. Africa, Europe, Asia and the Middle East exhibit variations themselves, if you’re a "lumper" you'd classify them all as the same and treat them as you do with modern people by noticing slight variation.

Variation of our species should be used more and I cannot stress this enough, the term "race" in which you still consist ( Negroid, Mongoloid, Australoid and Oceanic) are the actual bench marks in human differential. Only observing and comparing the amino acid sequences can we make a better assumption of who fits whom. The mixture in all peoples is too great to separate precisely alone on physical appearance. During World War 2 the physical appearence alone between Germans and Jews was compared by the shape of the nose and eyes for example.
