In principle, population segments with a lower reproduction ratio are
simply going to be replaced with time by those with a higher ratio. Of
course, it appears plausible that the latter would carry with
themselves the genetic/memetic endowment to maintain or expand such
ratio. Were this not the case, I assume that to go extinct in favour
of something else would not be single populations within a species,
but the species in favour of other ones.
