"Groups dying out" is not needed. So long as there is a selective advantage
for an allele (i.e., having the trait associated with the allele leads to
greater reporductive success--more offspring reaching reproductive age) then
that allele will replace a competing allele in the species (and assuming
that there is species wide mating).
