(RTÉ News) – The skeletal remains of a 4,800 year old dog found in the Neolithic passage tomb at Newgrange has been used by scientists to establish new information about how dogs became domesticated.

The major international study by scientists at Trinity College Dublin and Oxford University has found that wolves may have become domesticated dogs twice in the past, rather than once as previously thought.

The finding challenges the previous theory that humans first domesticated dogs in either Europe or Central Asia, but not both.

The research, published in the journal Science, involved the team at Oxford extracting the female line genetic material, known as mitochondrial DNA, from 59 ancient dogs that lived between 14,000 and 3,000 years ago.
