wouldn't the theory of evolution predict that life has no need to evolve
when it wins? or no way to evolve if it loses?
Yes, and so it does. That is why alligators are relatively unchanged
after hundreds of millions of years. That is why dinosaurs were the
dominant land animals for tens of millions of years, until an asteroid
impact changed the environment radically, overnight.
Random changes to the genome, as the result of imperfect copying, are
unavoidable. Differential survival, due (in part) to changes in the
genome is also unavoidable. Ergo, evolution is unavoidable.
There is nothing more deceptive than an obvious fact. - Arthur Conan Doyle
