Organism Survives 100 Million Years Without Sex

zyl0x writes "The Times has an interesting article online on the discovery of a 100-million-year-old micro-organism which has survived its entire lifespan without sex." From the article "A tiny creature that has not had sex for 100 million years has overturned the theory that animals need to mate to create variety. Analysis of the jaw shapes of bdelloid rotifers, combined with genetic data, revealed that the animals have diversified under pressure of natural selection. Researchers say that their study "refutes the idea that sex is necessary for diversification into evolutionary species".

    Who ever said sex was necessary for diversity? It just speeds it up - what's the big deal about this discovery? There are a crazy number of organisms that don't have sex and have changed a hell of a lot over time.

    Do you even know what murder means?

    How on earth can you kill someone who hasn't even been born yet?
    Next you'll be saying woman who have periods are murderers. ...that's another embryo aborted. In your opinion we are all genocidal maniacs, since we could have all reproduced millions of times but have not (something to do with rape laws) and so millions of embryo's have been effectively aborted via periods which could have otherwise formed children.
