Yes.Can a specie be simple life? Leroy's model of evolution predicts that species can evolve into a simple life. Leroy's model of evolution also predicts that species can go extinct. So if a species can go extinct and that species is a simple life, then that would mean that a model of evolution does predict that a simple life can go extinct and/or disappear.
Agree?
Yes.Species that go extinct and/or disappear does not exist today.
Agree?
No.So Leroy is either arguing that simple life species cannot go extinct or he is ignoring that simple life species can go extinct. This is the only possible way that Leroy's OP argument is able to work.
Agree? Or is it just going to be ignored and continue with repetition?
You are victim of a category error. @leroy doesn't talk about species, you do. Leroy is talking about classes of complexity, not about single species. The thing isn't that single species of lowest complexity have gone extinct. All species of lowest complexity have gone extinct, over all domains. And none have ever gone back to lowest complexity. Also, we have no fossils of lowest complexity species.
