Man's best friend came about more than 33,000 years ago

A latest research has suggested that man's best friend has come after generations of wolves scavenged alongside humans over 33,000 years back in south East Asia. According to the first study of dog genomes, dogs became self-domesticated with their slow evolution from wolves that came along humans in the hunt.

This has shown that the first domesticated dogs came nearly 33,000 years back, migrating to Europe, instead of descending from domesticated European wolves 10,000 years back, as thought earlier.

Since long, scientists were baffled over how the best friend of man came into existence, but there has been a conflicting proof on when and where wild wolves were tamed for the first time.

In a study, among the biggest studies of its kind, Professor Peter Savolainen along with his colleagues have sequenced the genomes of dog family’s 58 members which included grey wolves, native dogs from south-east and north-east Asia, village dogs belonging to Nigeria, and breeds collection from the rest of the world, like the Afghan Hound and Siberian Husky.

Published in Cell Research, the DNA analysis has discovered that the ones from south-east Asia had more degree of genetic diversity, and were most linked to grey wolves most closely. Grey wolves are the ones from which domestic dogs evolution has taken place.

Prof Savolainen, of the Royal Institute of Technology, Solna, Sweden, said, “This indicates an ancient origin of domestic dogs in southern East Asia 33,000 years ago”.
