Excuse me, aren't most Orangutans red haired? I suspect the gene for red hair goes back a bit farther than the Neanderthals. In fact we once had a horse (pony actually) who was a nice shade of copper/red, we called him "Little Red" (he was also very small, barely legal in Shetland class) in contrast to the "Big Red" who play about a mile from the fairgrounds where we most often showed "Little Red".
I can't vouch for "most Orangutans," but the few I've known very well sure looked good at closing time.
In fact I'd have sworn they weren't Orangutans.
They turned out, upon close examination of their evidence, to be not real redheads.
