Resumen de Paws for thought on dog-wolf split
An analysis of a bone from a newly identified ancient wolf species suggests that dogs may have split from wolves as early as 40,000 years ago. Now Love Dalen from the Swedish Museum of Natural History in Stockholm and his colleagues have sequenced the genome of a wolf that lived 35,000 years ago in Taimyr, Siberia. This allowed them to recalibrate the rate at which genetic differences have accumulated over time and better reconstruct the evolutionary tree. They found that dogs and wolves must have split into different lineages between 27,000 and 40,000 years ago, bringing the DNA and archaeological evidence into line.
