Help I Can't Think of a Title Devoid Of Tastless Sheep Jokes

You can't go wrong with gay sheep jokes, to start with, but this article contains some interesting science, too. Turns out that around 8% of rams actually prefer other rams, and "will swiftly pounce on any ram stuck in a fence, the sheep equivalent of prison showers". Ewes, too, might be lesbian, but since female sheep express a desire for sex by standing still, no-one's quite sure (and there may be a lot of frustrated female sheep).

The real punchline, though, is that an actual biological difference (in the size of the hypothalamus), identifiable from the third trimester of pregnancy, has been identified as the cause of homosexual behaviour in sheep. Sheep really are born gay or straight, the first hard evidence scientific evidence of this in mammals.

It's worth reading the whole article, but this fact alone, and the distress it should cause religions the world over, will have me sleeping very soundly tonight.
