Hey, just for anyone interested in it. There is a rather interesting article from 9th April in Nature named: "Evolution: Scandal! Sex-starved and still surviving"

Thats a very interesting read in fact. It shows a theory of how Bdelloid rotifers can survive already for millions of years without having ever any sex. Really cool stuff considering that those animals have some astonishing superpowers like surviving extreme drought or radiation (it needs 1000 Gray to make them infertile). Not to forget that they can resist pathogens others can't and eat them instead of getting killed.
