Disinterested Affection: Dogs, Humans and Evolution: Ancient wolf genome reveals an early divergence of domestic dog ancestors
http://dognaturalhistory.blogspot.com/2015/05/ancient-wolf-genome-reveals-early.html
Tuesday, May 26, 2015. Ancient wolf genome reveals an early divergence of domestic dog ancestors. The genome from this ancient specimen, which has been radiocarbon dated to 35,000 years ago, reveals that the Taimyr wolf represents the most recent common ancestor of modern wolves and dogs. The DNA evidence also shows that modern-day Siberian Huskies and Greenland sled dogs share an unusually large number of genes with the ancient Taimyr wolf. The power of DNA can provide direct evidence that a Siberian Hu...

Feeding dogs would give the dogs a reason to follow hunters, and cooperate with humans. In a forthcoming paper Tsutaya et al. Mitchell propos...

Thursday, December 8, 2016. Dogs and wolves MRCA 33,000 YBP. Dogs may be older than previously thought. The origin of dogs has inspired a lingering controversy in academia. Where and when did dogs first split off from wolves? One of the top dogs in this dispute, population genetics expert Peter Savolainen of Sweden's KTH Royal Institute of Technology, isn't about to roll over. He hopes his latest research will finally settle the matter. But apparently, those researchers were thrown off the scent, accordi...

Monday, December 1, 2014. More on paleolithic hunters and dogs at Predmosti. This year-round settlement also yielded a large number of canids remains, some of them with characteristics of Palaeolithic dogs. Were these animals used to help hunt mammoths? To answer these two questions, Tübingen researcher Hervé Bocherens and his international team carried out an analysis of carbon and nitrogen stable isotopes in human and animal fossil bones from the site. Working with researchers from Brno and Brussel...
