So "survival of the fittest" means those who are fittest now, will survive later.
So IMO it's a perfectly logical and valid term, and it's nonsense to say it means "survival of the survivors" as mentioned before.
As i did not write "survival of the survivors,' and although i understand why it was written, i have no reason to and am not obliged to defend it.
I think you're missing a point here, McT. Present and future do not apply as determinants of the meaning of survival and of fitness in the context of individuals in an evolutionary process. The means by which a individual is determined to be fit, is whether or not that individual survives--therefore, no comparative or superlative statement about fitness is applicable, it is an absolute condition. Survival demonstates fitness; failure to survive demonstrates "unfitness."
Spencer used it, however, with reference to "social evolution," and referred to individuals or groups of individuals. To that extent, whether or not he knew, he was describing the effect of adaptation on a species as opposed to the individual. An individual may survive, but fail to reproduce. The members of a
species which is "fitter," or most fit, will not simply survive, but will have a breeding opportunity, and pass on their genetic material. To that extent, the rather clumsy expression, "survival of the fittest" might be applied to species, or groups, as opposed to individuals.
However, even then it is not an absolute governing principle. A species which is "more fit," or "most fit," may thrive and prosper, and fill more ecological niches, and be prepared to exploit more or new food sources. That does not mean, however, that the "ur-species" from which it descends is necessarily doomed. If conditions which no longer favor the adaptation arise, and there are members of the earlier form present, they may in their turn have a better breeding opportunity, prospering in their turn, while the adapted species languishes in conditions for which its adaptations do not confer an advantage.
And that is why Spencer ultimately failed to make a plausible case with his "social Darwinism," because he oversimplified the processes which Darwin and Wallace described, and he (Spencer) also oversimplified the determining factors and their consequences among human social groups. So, for example, the Amish and the Mennonites and other such religious groups who eschew modern technology continue to survive in our world, despite the putative advantages that the rest of us enjoy through having embraced, or our forebears having embraced technological advances.
Any way you look at it, the expression "survival of the fittest" is a naive, and rather dullwitted contention.
In my never humble opinion . . .
