Apes and humans have similar parts for similar jobs so therefore we have very clos genetic resemblence.
My job is a house painter. Also, i drive, mess around on my computer, etc, etc. Joke. Ok, i know what you are saying. Without more info to back up this idea, i would have to guess at the specific 'jobs'. Let's say upright walking is one action for which certain gene sets are used. Humans, apes, birds walk upright. Do the genes sets for walking upright (if your claim is correct) in these 3 species match up? I don't know, but i think that the arguement comes from trying to prove a preset conclusion.
