Humans and Canines:

More evolutionary research

A recent paper in PLOS Genetics, by J. Pritchard, PhD, professor in the department of human genetics at the University of Chicago and J. Pickrell, also a U. C. researcher, now at Harvard, described a software model they developed that can infer the history of population splits and mixtures within a species, based on modern DNA. Pritchard and Pickrell tested their theory, using DNA models from 55 human populations, with interesting results.   See eScienceNews:  >>>

Pritchard and Pickrell also tested their DNA model on 82 dog breeds and found,  for example, boxer and basenji breeds of dogs trace a large portion of their DNA (nine percent and 25 percent, respectively) back to wolves after domestication. That is, these two breeds did again interbreed with wolves for a significant period of time—long after humans began domesticating them, and following domestication of the other ancient dog breeds.
