Humans are obviously above animals in intelligence, simply because we have the ability to experience more of the world. Everything is shaped through experience, and thanks especially to technology, we have intellect right at our finger tips. There is a difference between intellect and experience, but to gaining intellect whenever you please is an experience in itself. Humans are constantly evolving, mainly because a species can never actually stop evolving. For a human to stop evolving, well, that would be a plight against existence itself. Humans are becoming smarter and more aware as time progresses. It used to be that everyone blindly believed in a God out of fear from the Church that so oppressed them. Now, humans are making their own choices on what they believe, which is a clear evolution of humans and society as a whole. (although, western society is mostly evolving in a materialistic way thanks to the government, but that is a different discussion) I theorize that animals, naturally, must also constantly be evolving, but due to hinderances such as 4 legs and inability to go farther than their habitat because of lack of food resources, they cannot experience much of anything. This is what has confounded them to being simply "animals." We were at one time neanderthals, and evolved into cro-magnons (through the missing link of course, but what that could possibly be has too many theories to go into), so something gave us that extra boost. Animals aren't so lucky to receive that extra boost, so their evolution works at what is seemingly a severly lower rate than our own. Everything for us in this world is shaped through perception and experience, (hypercommunication and intervention from higher beings is a possibility, too, if that's your belief) so quite simply, animals have just been unjustly fated to a restraining and slow evolution because of the rapidly evolving human race. Industrialization and agriculture have raped animals of their chances to ever rapidly evolve. This was all just thought up on the spot, but i still believe it has relevance, haha.
