Good info.
"Genetic diversity, in this instance, seems to be result of a series of interventions by a series of intelligent designers."
Humans did not cause any of the genetic variation; they just selected which ones they wanted after the fact.
I wonder if our canine friends have conversations like this:
Spot: You know, I have a theory that our human masters may have intervened in our development. That our current condition may have been the result of an "intelligent design," if you will.
Rover: You're an idiot. You're ignoring the mountains of overwhelming scientific evidence that we just evolved completely by ourselves. What are you trying to do - force us all to pray to your human gods? Throw us back into the doggie dark ages before pet salons and canine massages? Your stupid, idiotic ramblings are an insult. Where did you come up with this nonsense? While you were chasing your tail? Did I mention that you're an idiot?
