Scientists have discovered a parallel branch of human evolution
Secrets of the past: Scientists have discovered a parallel branch of human evolution. Anthropologists have found that the so-called people rudolfskai, who lived about 2 million years ago, was not a variation of Homo habilis, and representative parallel lines of evolution of the ancient people
Conclusions of scientists are based on the analysis of the three new finds in the town Koobi fora in Kenya, famous for its remains of ancient people. According to archaeologists, they found the bones very similar to discovered in the seventies of the last century in the same area of the skull KNM-ER 1470. His owner called rudolfsson man (Homo rudolfensis). Whether was he a separate species of hominid or just a special variation who lived at the same time of Homo habilis (H. habilis), was the subject of dispute among archaeologists directly since the discovery of the skull.
New findings suggests that H. rudolfensis really was a separate species of the genus Homo existed parallel to H. habilis. First, found facial bones belonged to a young hominid, and was significantly less than that of KNM-ER 1470 but had exactly the same structure. Second, the lower jaw in humans rudolfskai was an unusual U-shaped and are not typical for H. habilis V-shaped. The two species differed also by the structure of the teeth.
Discovery of the archaeologists suggests the existence of two parallel lines in the evolution of the first representatives of the genus Homo. Some of them gave rise to Homo erectus (H. ergaster), which existed some time together with rudolfsen and skillful, is not clear. Moreover, it is not clear which of them was the direct ancestor of modern humans. To approach the answer to this question will be possible, if new remains will be able to extract DNA suitable for sequencing quality materials .
