How long have we known our best friend?
Researchers know that humans began domesticating dogs before
agriculture began (~10,000 years ago), but just when and where did the
wolf become the dog? Previous research points to the Middle East or East
Asia as the focal point of dog domestication and the origin of some of
the oldest breeds of dog. The oldest dog fossils are about 36,000 years
old.
Now, a recently discovered
fossil in Siberia is raising more questions. DNA was extracted from the
tooth of the fossil and analyzed, revealing that the tooth is about
33,000 years old, belongs to a canid, and that the canid is most closely
related to modern dogs and prehistoric canids of the Americas. It seems
our furry companions still have a few secrets of their own.
