or "gay" animals? I'm just trying to find some articles which supports that. Thanks for your concern.

Asexual animals? Thats anything that reproduces without sex. There are a few, though I can't think of any of the top of my head. I think there's a lizard?

An interesting one for the 'other side' is flies. All true flies are Bisexual. Every individual of every species of every family all the way up to order level. (where the definition of 'flies' is placed). Strange but true.

Bonobos will have sex with anything, and I think Vultures are occasionaly gay.

Some whiptail lizards in the genus Cnemidophorus reproduce parthenogenetically. For instance, the species C. exsanguis, C. neomexicanus, C. uniparens, and C. laredoensis all reproduce asexually, and males are not known to exist in these species.

Other members of the genus Cnemidophorus reproduce sexually, and have both males and females. Interestingly, in order for a female from an asexual species of Cnemidophorus to ovulate, it seems to be necessary for her to "mate" with another female, who displays "pseudo-male behavior." (Obviously, no exchange of genetic material occurs, however.)

This suggests that the loss of sexual reproduction in these species is quite recent.

As far as I know, these are the only reptiles that are known to reproduce asexually, and asexual reproduction does not naturally occur in birds or mammals.

Cheers,

Michael

Homosexual pairing has been observed and reported in many, many mammalian and bird species over the years. <a href="http://www.amazon.com/exec/obidos/tg/detail/-/0312192398/qid=1031819688/sr=1-1/ref=sr_1_1/002-3121769-0856050?v=glance&s=books" target="_blank">Here's</a> one interesting book on the topic.

DNAunion: Fragmentation is another method of asexual reproduction practiced by some animals. For example, at least one type of planarian can "cut itself in half" after which the missing parts of each half are regenerated.

As far as homosexuality in animals, sure its rampant. I saw a half-hour show on TV that featured gay dogs, gay dolphins, etc. It was on the Discovery channel....no wait, it was on South Park! :-)

Within the past year there appeared a serious
nonfiction work detailing same-sex and auto-sex behaviours among non-human animals. Sorry i can't remember title or author. >>>> Group tell?
