THEY may not be man's best friend, but wolves in North America do have a
little dog in them.
Geneticists investigating the relationships between members of the dog
family have found that wolves with black pelts owe their distinctive
coloration to a mutation that first arose in domestic dogs.
Domestic dogs were bred from the grey wolf Canis lupus, but exactly when and
where that domestication took place, and how various modern breeds of dog
relate to wolves, has been a matter of debate.
Now Robert Wayne at the University of California, Los Angeles, and his
colleagues are revealing these relationships. The team use DNA chips - which
are able to examine some 53,000 genetic variants - to determine which
animals are most similar genetically.
The results so far have shown that domestic dogs are most closely related to
wolves from the Middle East. If domestication took place elsewhere as ...
