Ancient DNA traces the woolly mammoth's disappearance

...hen the glaciers reached their fullest extent. The findings also offered early human hunters a potential alibi; they didn’t come on the scene in large numbers until even later. In search of a general pattern in the new study, Barnes and Lister’s team looked to the extinct woolly mammoth. What they found, h...
