I loathe pop sci interpretations of animal behaviour applied against human behaviour (which includes the context of the parent of your comment) but humans are apes. The 'Great Apes' are chimps, gorillas, orangs, and humans.
Thanks for the correction, I guess I was wrong on that point, though hopefully the actual intended meaning of my statement remains intact.
EDIT: Well, according to Wikipedia, "Great Ape" is a common name, not a taxonomic label, and is only sometimes used to include humans. I, personally, would advocate not equating the term "great ape" with the hominidae family.
