that's very interesting. I find it impressive that we have been able to breed dogs to take advantage of specific features, and get more uses out of them. smell is just one of many features that dogs now provide for us.
I also understand the Neanderthals lacked the ability to understand facial expressions and things like simple hand gestures. so they had almost no way to communicate with one another. although, I understand that they were in many ways the more intelligent species. they made better use of there resources, and were more efficient. if they had found an effective way to communicate, they would proberly have ended up being the dominant species.
