The Evolution of the Tina

The oldest extant branch of life is the Tino 4s, which go back 700 million years. Species don't survive more than two million years, three million years. This is all groups. These are other higher taxonomic groups. A genus and species. But you're talking about today's species as part of a group that evolved. And none of you picked number one, so we'll start there. Who picked nobody picked the shark? I did. Bob did. I'm going to go with the shark. It must be.
