- I will agree that given fitness as survival of your genes, and survival of
- the species as the intended meaning of survival in SOTF, SOTF is not a
- tautology. On the other hand, it doesn't a whole lot of interesting

- You seemed to be saying that "fittest" has a naturalistic *definition* -- in
- terms of things like cardiovascular efficiency, etc. I don't think it does.
