I learned recently that dogs have been found to have mutations that are equivalent to a genetic mutation in humans that would make a person more sociable and less intelligent.
I read about that too.  I wonder why that is?
It's an interesting new discovery. But unfortunately the origin of the domestic dog still isn't clear.
dp you think humans can be selectively bred like dogs?  Maybe thats why.
Human evolution is also interesting, but I'm not sure. There are dogs that don't selectively breed though -- the dingo is an example. It exists in the wild but can't be domesticized!
That's very interesting.  They are kind of like wolves.
Yes indeed they are! Coyotes are also related to wolves, they are slightly smaller than the related eastern and red wolf.
I've seen coyotes near me.  They are very scary.  
Coyotes live near me as well, I've always found them to be very cute.
I've heard stories of them attacking domesticated dogs.
