MADRID “I am pleased to introduce a new species of human ancestor Homo We have called Naledi.”. So Professor Lee Berger, an anthropologist at the University of Witwatersrand, South Africa, which together with National Geographic and other institutions in Johannesburg discovered what may be the oldest specimen of the genus Homo.
The announcement was presented today was made today, but the finding was in 2013 in the chamber of the cave Dinaledi Rising Star of South Africa.
The remains of Homo Naledi came from over 1550 fossils. The bones of 15 individuals of the same species, allowing researchers to document and describe the skeleton of the new ancestor at length
found. The new oven has 1.5 meters and 50 kilos plus features of Australopithecus, the first move of bipedal manner and lived in Africa for more than 4 million years ago until about 2 million years. The new species appears to have a slimmer body and often.
The complete description of this new kind of hominid is published today in the journal eLIFE. It is still unknown what year would have lived the Naledi, because scientists could find no other animal fossils that allow an estimation. However, the first place this fossil analysis between the first homo-about 2.5 million years. If Newest out (less than a million years), it would be proof of coexistence in African species of the genus Homo very different from each other and that would rebuild the complex evolutionary history.
According to Markus Bastir , researcher at the National Museum of Natural Sciences of Spain and co-author of the study, “Homo Naledi is a mosaic of characters so: it has a funnel-shaped trunk, not barrel shaped like men today, but like a pyramid, a feature of the Australopithecus or the great apes such as chimpanzees. “
Bastir said the new species” has a small skull, the shape of the first representatives of the genus Homo, as habilis or erectus and a very small cranial capacity, about a third of what occupies our current brain. ” The tips are virtually identical to those of modern humans.
“His hands are capable of handling objects that men have now but his fingers and phalanges are curved, which, according to the anatomical experts means that would be adapted to live in an arboreal habitat, “explained the scientist.
” Both the wrist as the bones of the palm are very modern, indicating that, although not found tools on the site, with that anatomy could use them perfectly, “said the researcher, adding:” The feet are also like ours, except that the fingers are slightly curved, which means they would be adapted to live in the trees and earth. “
