Pre-Homo human ancestral species, such as Australopithecus africanus, used human-like hand postures much earlier than was previously thought
Some of the morphological characteristics of the human hand are different from that of other primates enabling us to grab objects with precision and use them exerting a force. Yet, how did our early human ancestors use their hands? This question was long debated among scientists. Anthropologists from the University of Kent, working with researchers from University College London, the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany and the Vienna University of Technology in Austria, have produced the first research findings to support archaeological evidence for stone tool use among fossil australopiths three to two million years ago and found that Australopithecus africanus used their hands the way modern humans do.
