![]() The results indicate that the hominids reached a prenatal growth rate setting them apart from all other apes between one million and a half million years ago, long before the human species itself evolved (between 300,000 and 200,000 years ago). ![]() Tesla Monson and her team, which also includes Andrew Weitz, of the Department of Environmental Sciences at WWU, scientists from the Berkeley Geochronology Center (U.S.), and the CENIEH, studied fossils of the primate group which includes the Old World apes and monkeys, as well as data compiled from fossilized molars and skull fragments from the period of the terminal Miocene up to the Plio-Pleistocene, running from about six million to some 12,000 years ago. The teeth are indicators of what goes on elsewhere in the body, and this study, published in the journal Proceedings of the National Academy of Sciences (PNAS), shows that they can be used like a map to help untangle the effects of the interplay of genetics and development, as well as to improve our understanding of the history of life in the past.
