It's another of those bad days for creationism, like most days in biology research, in fact.
This time, one of their favourite misrepresentations - the so-called Cambrian Explosion - just got a lot harder to misrepresent. Fossil evidence has been found of a much earlier complex multicellular, worm-like organism.
This gives the lie to any claims that the Cambrian biota appeared suddenly without ancestry, as though some celestial designer arrived on Earth one day and plonked a whole lot of different, fully formed species, in the sea.
