The
origin of dog domestication in Europe with Robert Wayne; Richard Lenski tracks the adaptation of bacteria over 50,000 generations; Robert Services describes the prospects of a new contender in solar technology.
This lineage traveled from the site
of dog domestication in Central Asia to Europe along with an early dog expansion perhaps 10,000 years ago.
Online News Editor David Grimm talks with Sarah Crespi about reporting on this story and what it says about the
history of dog domestication.
Robert Wayne, an evolutionary biologist and dog domestication expert at the University of California, Los Angeles, is also skeptical: One lesson learned from genetic
studies of dog domestication is that looking at dogs living today «are a poor guide to domestication events which may have occurred more than 27,000 years ago.»
Although neither Wayne nor Savolainen were involved in the current study, both joined Larson in 2013 as part of an international collaboration to solve the
mystery of dog domestication once and for all.
The work could rewrite the thinking about some of the earliest
days of dog domestication, and it suggests that scientists interested in the beginnings of the human - canine relationship should be paying more attention to early Arctic peoples.
Adam Freedman of Harvard University and an international group of collaborators compared DNA from three breeds of dogs (a boxer, a Basenji and an Australian dingo) to that of three gray wolves (Canis lupus) from Croatia, China and Israel — three locations proposed as
centers of dog domestication.

Some analyses suggest that the original domestication
location of dog domestication was in East Asia; others that the middle east was the original location of domestication; and still others that a later domestication took place in Europe.
The exact
date of dog domestication is not known, but some experts like University of Liverpool's Keith Dobney, an archeologist, says that it could date back to over 30,000 years.
He thinks that they may hold the secret to the origins
of dog domestication.
