I stumbled across this link on another board I frequent:
Homosexuality in Animals Exhibit
Personally, I thought this was fascinating. I didn't know so many animals exhibited homosexual tendencies; I thought it was just us, the dolphins, and the Bonobos. Kind of pokes holes in the whole, "Homosexuality is against nature" argument.
Is this exhibit 'politically motivated', as its objectors claim? Yes; one of the organizers is quoted as admitting as much. Besides, it's hard not to address homosexuality in a public manner without there being some political motivation involved. Which is sad, because the science there is real; these examples that exist in nature didn't spring up as a reaction to the gay marriage debate. It's not like these zoologists made up gay penguins and male-on-male flamingo love. Still, science does not happen in a vacuum, as much as we'd like it to, and so there's always going to be political overlap on scientific discovery. Anyway, interesting stuff.
