The finds come from beneath this 39.3 ka BP tephra.
The analysis shows the Uluzzian levels in which the teeth were found must have been deposited by modern humans, not by the Neanderthals as earlier thought.
The data show that the find is more than 6000 years earlier than previously thought, based on a Bayesian model constructed using bone dates treated using the ORAU ultrafiltration method.
Exhaustive analysis of the teeth and comparison with a dataset of modern human and Neanderthal teeth by Tim Compton and Chris Stringer at the Natural History Museum in London showed that in the majority of traits, the KC4 teeth had modern human, rather than Neanderthal characteristics.
Staff and students at the RLAHA had the chance to chat to David during afternoon tea in the lab.
19/10/2010 The theory that later Neanderthals might have been sufficiently advanced to fashion jewellery and tools similar to those of incoming modern humans has suffered a setback.
, suggests that the position of key finds in the archaeological layers of the Grotte du Renne at Arcy-sur-Cure in France may not be trustworthy.As such it predates all previously known humans in northwestern Europe, overlaps partially with the very earliest dating evidence for the Aurignacian and tells us much about the dispersal rate of our species across the continent.In the second paper, Katerina Douka and an international team published new data from the south of Italy.Doubts were raised later because trace animal collagen glue was found on the specimen.A renewed attempt to date it failed, so Roger Jacobi and Tom Higham dated samples above and below the find spot of the maxilla instead.
