selection doesn't even apply directly to the individual, but to the survival of individual genes through individuals.
if a gene establishes itself within the genepool of a group, that is because it has been beneficial to every individual (and the genes that survive through that individual), by it's own merit - not by merit of being widespread in the group already, along the way.
