"This the very first moment of animal evolution preserved in the fossil record."

Evolution implies change. More specifically, change from one species into a different species. To see a 600 million year old fossil and say "this is change" seems silly. Do they know what came before? Do they know what came after? How can they recognize this "moment of animal evolution"?

They found an interesting thing which they had not found before. That's all.
