Wrong again.
Paedo-morphogenesis is why dogs look the way they do. Its also the reason humans look as we do, but the reasons are different.
Paedo-morphogenesis is the evolutionary mechanism to incorperate child charateristics into an adult.
Generic dogs(standard mutt look found all around the world) look as they do because when bred for friendliness what actually happens is some puppy behavior charactirists are breed into adults. The modifying of behavior development also tended to modify physical development.
The was actually proven when a Russian scientist decided to breed friendly foxes for fur farms. He spend half his life on the project, in the end he had with foxes that looked like short mutt dogs and had dog like fur useless for coats.
In humans paedo-morphogenesis is considered to be the mechanism by which we got our larger craniums relative to our bodies than apes have. A secondary effect is that we dont have protruding jaws.
