Wayne, I once had a beef cow that refused to mate with a bull -- she did lactate and help nurture another cow's calf. The cow may have been homosexual or asexual. I've heard livestock owners say that cows frequently display homosexual behavior (mounting other cows) but a cow exhibiting excessive homosexual behavior including avoiding bills is usually sold for slaughter. As I understand it, in nature (including humans) there is a wide and continuous spectrum of sexual behavior ranging from pure heterosexuality to bisexuality to pure homosexuality, and this range of behaviors is further modified by a varying continuum of sexual intensity from hypersexuality to asexuality.

I will not be checking email during those periods, but will respond to as many email messages as possible during those hiatuses. A third expedition following those is likely, but the period of hiatus is iffy.] Here is my parting question. Please feel free to post it on other lists. Re: Homosexuality in animals other than Homo sapiens. We know that homosexual behavior occurs in other species in some forms (Bonobo chimpanzees [Pan paniscus], for example), and we know that hermaphrodites of some species fertilize each other simultaneously. But my question is in which species other than humans, does EXCLUSIVE homosexuality, especially in the form of pair bonds, occur? WT I'll pick up my answers in late April. If I have time, I may be able to respond to some today. Please respond on-list, and not to me personally.
