And when I read your post it sounded like you were saying humans were the only one with a 21st chromosome. I know that isnt what you were saying. But it does bring up a peculiarity in that the number of chromosomes is not linked in any way to intelligence or complexity. The animal with the most chromosomes (I believe) is the hermit crab, and the organism with most chromosomes overall is some kind of fern. Ehhhh, forgive my ignorance and inability to read the whole post before replying. lol
