Latest Bdelloidea Stories
Up to ten per cent of the active genes of an organism that has survived 80 million years without sex are foreign, a new study from the University of Cambridge and Imperial College London reveals.
They haven't had sex in some 30 million years, but some very small invertebrates named bdelloid rotifers are still shocking biologists â€“ they should have gone extinct long ago.
This odd, microscopic, freshwater animal is making news once again, this time for the startling discovery of numerous chunks of foreign DNA in its genome.
Birds and bees may do it, but the microscopic animals called bdelloid rotifers seem to get along just fine without sex, thank you. Whatâ€™s more, they have done so over millions of years of evolution, resulting in at least 370 species.

In a paper published in this week's Proceedings of the National Academy of Sciences (PNAS), MBL scientists Irina R. Arkhipova and Matthew Meselson provide evidence that suggests bdelloid rotifers--which probably gave up sex at least 50 million years ago but have still evolved into 370 species--handle DNA transposons more efficiently than other asexual species.
