Unexpected Facts About Origins of Dogs

Scientists have managed to uncover the origin of the dog. Unexpectedly, the origin of the dog is different from that envisioned all along.

To uncover the origins of one of the mammals closest to humans, scientists from Oxford University studied the genetic data and compare it with the existing archaeological evidence.

They investigated a series of genes from the 4800 year old ancient dogs were found in the Tomb of Newgrange in Ireland.

Scientists also examined the mitochondrial DNA (DNA material in the cell organ that serves to generate power) of 59 other ancient dogs that lived between 3,000 and 14,000 years ago, and compared them with 2,500 cells genetically modern dogs.

The results show clearly that there is a genetic difference between modern dog populations that currently live in East Asia and Europe.

That suggests, a good friend of this man is the result of the evolution of two distinct wolf populations living in two different places, and experience taming more than once.

Quoted by the Daily Mail last week, Greger Larson, a researcher from the University of Oxford, said that the domestication of animals is rarely discussed and it took a lot of data to prove it.

Taming itself not only in dogs. Keith Dobney of the University of Liverpool found that wild boar are also domesticated twice, in China and Anatolia, Turkey.

Previously, there are several theories that develop related taming dogs. One theory suggests, initially humans actively taming, then breed wolves.

As according to another theory, the wolf itself be benign because it follows the human and eating human leftovers, or loiter near human settlements, transformed into a dog and become friends with humans until now.
