Time: 10 minutes
Overview
In March 2010 German researchers announced that they had managed to extract DNA from the 40,000 year old fossil bone from a child discovered in a Siberian cave and that it didn't match up to the known genetic sequences of either humans or Neanderthals! This news brief examines the evidence in more detail and considers what that evidence might — or might not — mean about such claims.
Evolution and Phylogenetic Analysis
