Well this finding shows that there really wasn't an explosion of complex multicellular life. The Cambrian explosion seems to be the appearance of organisms that were more easily fossilized. That doesn't mean there weren't complex organisms before the Cambrian Explosion. This very exciting finding shows complex multicellular life predates the Cambrian explosion. We now have data from an epoch where we didn't have it before. This is fantastic news!
BTW, What is a ROM scientist? Read Only Mollusks?........
