Researchers have compared dog mutations to genetic changes in humans that trigger reduced intelligence. Looking at my dog, I can believe that.
That's really interesting. Can you tell me more?
The genetics of domestication is really interesting because we are able to choose desirable traits and breed specifically for them. Maybe we like our dogs dumb.
I don't know I think dogs can be pretty smart....
I actually agree. I have had very smart dogs as well. I really recommend researching the study of domesticating foxes. It is incredibly interesting and was a research project started by Dmitry Konstantivovich Belyayev
That's interesting. Do you know why foxes?
I am not really sure. They found a way to lessen their fear of humans.
That's interesting. Do you know anything else about domesticating animals?
A bit about monkeys who are raised along side human children, but I don't think that is really about domestication, but does show how animals and humans can form a very strong bond. 
That's very true. I also think it's interesting how cats have formed a bond with humans too.
