Do animals need to sex to create variety?

The Times Online has an interesting article about an organism which survived 100 million years without sex.

Researchers say that their study "refutes the idea that sex is necessary for diversification into evolutionary species".

 

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".
