Genes don't get selected for when they propgate the species, they get selected for when they propogate themselves. Not always the same thing.

And from a genetic reproductive stadnpoint, a colony of social insects can really best be considered a signle organism, since the individuals comprising it all have the same genes, and only one of them reproduces. So from a genetic perspective, none of the individual organisms can have a 'self-interest' opposed to the 'interests' of the hive. A lion on the other hand doesn't share as many genes with some other lions offspring as he would his own, so he's ok with killing other lions and their offspring if it will help him have more succesful offspring.
The point Dawkins was trying to make I think was that genes have a tendency to code for phenotypic traits that result in their (the gene itself) own propogation, not that there is some gene that codes for a phenotypic trait of selfish behavior.
