Article OK except for where it claims "Domestic dogs are evolved directly from gray wolves: the evidence is quite clear on that now".
So dogs have evolved into the myriad forms we see now, whilst wolves have remained unchanged? I don't buy that. Wolves will have continued to evolve too in terms of both their physiology and behaviour. Sure, they're closely related but if we see dogs and wolves as having evolved along different paths from a common proto-wolf/proto-dog ancestor, that will probably give a more accurate and usable picture.
After all, sociologists don't draw conclusions about human society by looking at Chimps.
