Memes and meme complexes that win on group selection are quite different from ones that win on infectiousness (i.e. in the so-called Marketplace of Ideas).
-
do you mean group selection literally, or just prosaically to mean "the group that survived"? because there is no such thing as group selection
-
Group selection usually doesn't work at the gene level, but with engineered memeplexes that are able to exert approximate ownership of genetic lineages, it can work at the meme level.
-
But even on the gene level, multi-cellular organisms are the result of group selection. Though it requires rare circumstances: shared-fate and enforcable conformity.
-
As soon as a group of organisms has a shared immune system, that is, a concentration of power and the ability to impose an internal order, then it becomes useful to model it as a superorganism, and analyze selection pressures on the group.

genetic group selection has no plausible mechanism, it's still selfish genes driving the higher order patterns. to explain altruism beyond naive kin selection, look into bet hedging:https://twitter.com/paulsbohm/status/986856994891030529 …

I just gave a plausible mechanism, which has actually occurred in nature, and produced such highly coordinated group organisms (ourselves) that we forget they are composed of individual cells.

Not to mention their accounts of what causes disease. Didn't you find a good quote on that?
