Research reveals the link between primate knuckles and hand use

Research carried out by the University of Kent has found differences between the knuckle joints of primates that will enable a better understanding of ancient human hand use.Using samples from the Powell-Cotton Museum in Birchington-on-Sea (UK), as well as samples from Germany, Belgium and the USA, a team led by School of Anthropology and Conservation (SAC) PhD student Christopher Dunmore examined the internal bone structure, called trabeculae or cancellous bone, of great apes.
