I'm no biologist, but I'll take a stab at this. A human has more brain matter that functions better together than brains of other animals. This is evident by humans ability to talk, do math, think beyond instincts, and do other things.
i'd argue that abstract thought is more important to this point. i've seen some dolphins do some very intelligent things, and we know chimps can use language.
Now if you put a human brain in... an Ardvaark, it wouldn't be very useful to it. The Ardvaark doesn't have the vocal cords to talk or sing or whatnot, it doesn't have the hands to manipulate materials and create things like a man does.
irrelevant. these systems do not develop independently.
A man seems to have several qualities such as bipedal stance, hands, vocal cords for speech, forward facing eyes, etc... that all work together with his far surpassing brain design that put him above the animals.
lots of animals have hands, vocal chords, and forward facing eyes. not alot of animals today are bipeds though (although lots of dinosaurs were).
Exactly the point. There can be no more obvious an intimate relationship between us and God than his creation of us.
that's good. science studies god's creation. the problem arises in the fact that creationism does not, favouring man's bible instead.
