Dog origin ‘was in Central Asia’

Today’s dogs can trace their origins to Central Asia, according to one of the most comprehensive genetic surveys yet.

Dogs are the most diverse animal on the planet – a legacy of thousands of years of selective breeding by humans.

But they derive from wild wolves that were gradually tamed and inducted into human hunting groups – perhaps near Mongolia or Nepal.

The findings come from an analysis of DNA from thousands of pooches, and are published in PNAS journal.

Cornell University’s Dr Adam Boyko and his colleagues studied 4,676 purebred dogs from recognised breeds, as well as 549 “village dogs” – free-ranging animals that live around human settlements.
