Little creatures

Another organism justly famous for DNA repair, the bdelloid rotifer, has now been shown to be even more versatile than thought, apparently having the capability to incorporate genes from other life forms into its own genome.
And in equally astonishing news, an elegant experiment has revealed the adult form of a fairly complex larval crustacean to be a far simpler worm like creature, sort of like a butterfly changing into a caterpillar. A reminder that neither evolution or biological development always follow the path of greater complexity. Check out the video.
