Evolution never throws out a good thing once it's developed. So we're supposed to believe us losing our 'fur coats' is a good thing? Our ability to move swiftly with the agility of an animal? How come there are SO many animals that have these 'good handy developments' that they lost? If you say "they lost it because they developed something better" then how come WE lost all those good things just because we developed intelligence? Surely a fur covering and agility/precociousness doesn't interfere with that? Actually it does. The human body retains a lot of infantile traits. The large head in proportion to body mass, relative lack of hair, playfulness into adulthood. These are developmental delays that give benefits in trade for the loss of other traits. The primary benefit is brain size.

You might be interested in knowin that tame foxes have been bred for wild foxes. The primary method of breeding tame animals is to select ones that keep juvenile traits into adulthood. In the case of foxes, one of the traits linked to tameness (and intelligence) is the quality of the fur. Why fur should be liked to intelligence and behavior, I don't know, but it is.
