All small dogs originate from packs of wolves in the Middle East, more than 12,000 years ago

Imagine, packs of small yappy dog wolves roaming the plains of the Middle East.

A new genetic study, traced a gene called IGF1, that determines small size in dogs, back to the first domesticated grey wolves, which lived in this area.

Melissa Gray and Robert Wayne, from the University of California, led a team of researchers who surveyed a large sample of gray wolf populations.

She said,

The mutation for small body size post-dates the domestication of dogs. However, because all small dogs possess this variant of IGF1, it probably arose early in their history. Our results show that the version of the IGF1 gene found in small dogs is closely related to that found in Middle Eastern wolves and is consistent with an ancient origin in this region of small domestic dogs.


Their results were published in the open-source journal BMC Biology.

Previous archeological work in the Middle East has unearthed the remains of small domestic dogs dating to 12,000 years ago.

Sites in Belgium, Germany and Western Russia contain older remains, 13,000 to 31,000 years ago, but these are of larger dogs.
