Homosexualism in nature

Thanks to darwinian remiix journal I noticed museum exhibition devoted to homosexuality among animals.
On LiveScience page we find information:
“Homosexuality has been documented in almost 500 species of animals, signaling that sexual preference is predetermined. Considered the closest living relative to humans, bonobos are not shy about seeking sexual pleasure. Nearly all of these peace-loving apes are bisexual and often resolve conflict by the “make love, not war” principle. They copulate frequently, scream out in delight while doing so, and often engage in homosexual activities. About two thirds of the homosexual activities are amongst females.”
Those facts are nothing new but surprisingly big number of people have never heard of it or are deaf on such informations. I talked once with Christian fundie about that and his reaction was something like that: “What? Never heard of it”. I asked: “Haven’t you see even two male dogs together”? His answer: “What? No, never. And actually that is not true with homosexuality. Science is just one big fraud”…
Well, by such opinion there was no point of discussing it further. It’s hard to believe that people can think that way (read: to be so limited, stupid) but maybe it’s some kind of US specialty among fundies or like overweight people, fluffizm and so on… At least in area/environment I live, such statements would be not just faux pax but complete disgrace. It’s true that science often is overestimated and has many disadvantages but not to such degree! It shows complete lack of understanding what science in general is. Alas many scientists seem to forget it too…
Anyway, back to this fascinating exhibition:
“A first-ever museum display, “Against Nature?,” which opened last month at the University of Oslo’s Natural History Museum in Norway, presents 51 species of animals exhibiting homosexuality.”
More to it and other related sources is to be found on the site:
