Leipzig – Germany-biology report that proteomic analysis of 20 homo naledi The teeth determined that all the individuals to which they belonged were females, because each of them lacked a gene variant found only in biological males. The 300,000-year-old hominin fossils were discovered in 2013 by Lee Berger of the University of the Witwatersrand and colleagues in a remote chamber of South Africa’s Rising Star cave system. Study of the bones shows that they represent about two dozen individuals whose brains and upper bodies were small, but whose faces, hands, and lower limbs were like those of modern humans. Berger and colleagues previously suggested that homo naledi Individuals recovered from the cave were buried there, but critics responded that such complex behavior would be unusual for a hominin with such a small brain. “The most likely reason for these strong results, in my opinion, is cultural selection for burial after death based on sex and perhaps gender,” Berger said. Proteomic analysis also shows homo naledi shared a gene variant related to collagen production with paranthropus robustusA human relative with a giant face and teeth that lived in South Africa about one to two million years ago. It is unclear how the two species may have been related. “It’s still early days for sampling fossil hominins with ancient proteins, and we won’t know until we make a better, larger sample,” Berger said. Overall, the study helped researchers understand why so little variation was seen in the remains. homo naledi persons. “This is probably because they can all be of the same sex,” said Palesa Madupe of the Max Planck Institute for Evolutionary Anthropology.
