Ants Give Up On Males, Become All-Female Species

A few weeks ago, an old friend of mine was bemoaning her inability to understand men. I told her to take a close look at insects and everything will begin to seem a lot more cut-and-dried. Not to say you can solve all gender-related issues by looking at a beehive, but the more I look at insects, the more it becomes clear that the females are the real members of any given species and the men are essentially an adaptation necessary to breeding.

A little while ago, I posted about termite queens that produce asexually to make a clone of themselves, who carry on mating with the termite king after they've reached the end of their shorter life span. Well, the same publication, the UK's Royal Society B, has hit us with another whopper: Amazonian ants that have given up on sexual reproduction altogether. Yes, they're an all-female species.

According to BBC News, this sexless world comes with a slew of benefits. First, the ants don't waste any energy producing males (which, for many insects, don't do much apart from breeding). Think about it, you've combined two positions -- how's that for streamlining the business? Plus, this doubles the number of reproductive females produced each generation. Yep, you've come a long way, baby.

The downside? There's less diversity, which means one new parasite or disease can essentially wipe out the entire species.

So what might a sexless world mean for humanity? Less resistance to disease, sure, but we might be heading that way anyway with designer babies and human cloning. Might it also mean fewer wars and murders without all those masculine hormones and breeding instincts? Think about it...
