Bow, wow

Pooch breeds identified by genes.

Salient points:

1) One "ancient" branch, three recent ones, of canis familiaris.
2) The importance of functional genes in effecting the phenotype of the dog. That is, the three recent clades look very different, even if their origin was on the order of hundreds, not thousands, of years. Note that "ancient" breeds were re-bred from the genetic background of the canine population in the recent past (the same "look" can be replicated through selection biasing a breeding population).
3) Dogs are man's best friend if they can help us with understanding human diseases.
