The Beginnings of Animals

Our common ancestor with a backbone came, like, millions of years after that. It's not even able to move physically. This kind of brings up, i'm thinking of like, mollusks and clams. So we fall under a specific classification as of dutertomes which means in the embryo we develop anus first. And so anyway, there's all these reasons why om vertebrate animal maybe. No, in vertebrates come later. Even mosan ye, we're talking now like animals. They look like wet leaves. But really, it's actually the beginnings of an animal. We essentially differentiate when our common ancestors were and when we got to humans were vertebrates
