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".
