My favorites include Pharyngula and ERV.
Recently, I had the pleasure of reading The Frontal Cortex. I love the blog name. I am so curious about the brain that when I see anything related to it, I just had to go ahead and read it.
Almost a month ago at work, I read his piece on Gay Animals. My favorite lines are:
In fact, Roughgarden even argues that homosexuality is a defining feature of advanced animal communities, which require communal bonds in order to function. "The more complex and sophisticated a social system is," she writes, "the more likely it is to have homosexuality intermixed with heterosexuality."
Read the comments and you'd also agree with them. Like this one:
I think one reason for 'gay' animals might be that animals are horny and stupid.
A bored dog will have a bash at humping a cat*. A dog humping another male dog is not that much different. I've seen a few human-leg-osexual dogs in my time too.
Sorry for lowering the tone :o)
*check youtube if you dont believe me.
Interesting, eh? Yeah, thought so too.
