No.
What would be the 'science' that proves this?
Human Beings, Chimpanzees, Orangutans, Gorillas are all in hte Hominidae (sp?) or Great Ape family. Are Lions and Pumas cousins? If you consider them cousins, you would have to consider Humans and Chimps the same. Surely you dont disagree with scientists putting humans in the ape family right?
