A map of charismatic canid genomic variation

The Pith: Wolves and coyotes exhibit geographic population structure. The red wolf may “only” be a coyote with a minor admixture of wolf, instead of a “real species.”

I like dogs. For various structural reasons I am not able to live with a dog right now (not to mention the required investment of time & energy). But the whole military dog storyline associated with the killing of Osama Bin Laden has me thinking a bit more deeply of the co-evolutionary nature of dog-human relationships. Whether dogs have theory-of-mind is controversial, but there’s no doubt that they’re relatively well adapted to operate with humans relatively efficiently as part of a dual-species team. From an evolutionary and genomic perspective dogs are also of interest. Like humans dogs exhibit a huge range of phenotypic variation despite relatively recent common origin. The species which they presumably are derived from, wolves, are intelligent social creatures whose natural range is very expansive indeed. I believe that the general dynamics of evolution and genetics which are operative amongst canids can give us insight into the processes which shape our own species. In part that is ...
