Homo Naledi Used to have Tool-Friendly Hand Anatomy

After examining the fossil remains of Homo Naledi found in a South African cave, scientists said that they may have been handy with tools and walked much like a person. On studying the well-preserved foot and hand bones they said that they used to have many similar characteristics with our species along with some primitive traits useful for tree climbing.

Tracy Kivell, Paleoanthropologist of Britain's University of Kent, said that the wrist bones and thumb looks similar to those of modern people and Neanderthals. They also indicate powerful grasping and the ability to employ stone tools. The strongly curved fingers of the Homo Naledi species shows that they used to climb with their hands and are different from people and Neanderthals in this respect.

Jeremy DeSilva, Dartmouth College anthropologist, said long legs, the knees and the feet of Homo Naledi species are similar to those of humans meaning that they used to walk and run a lot. Despite of similarities, they used to possess a flatter arch, curved toes and a heel like foot which makes them slightly different from humans. "Our science has known for decades that upright walking, bipedalism, preceded brain enlargement over the course of human evolution. But never before has it been so obvious".

Though, Homo Naledi has human-like foot, they were having brain one-third the size of modern human brain. William Harcourt-Smith, Paleoanthropologist of Lehman College CUNY and New York's American Museum of Natural History, said that Homo Naledi used to have tool-friendly hand anatomy. Their curved fingers and toe bones made them more talented than modern humans.
