- I think fitness really pretty much is defined as survival, as Daryl has
- argued in other postings. (At least, survival of your genes.)
-
- I think the real content of "survival of the fittest" is that "fittest" is a
- naturalistic concept. While it is *defined* in terms of survival, it
- depends only on natural law. No supernatural agencies are required. Among
- a group of modern scientists and engineers, that is a relatively
- uncontroversial position, so the slogan sounds a bit quaint in this context.
-
- The main content of evolutionary theory is that *random* mutation is the
- only input to this process. So another sense of "survival of the fittest"
- is a negative one: survival of the fittest is the only thing driving
- evolution. This would not be true, for example, of Lamarckian evolution.
