Where group selection works, it is mathematically indistinguishable from kin selection, so you might as well use kin selection as your conceptual model.
I suppose I should have said, “where group selection works in nature.”
From the paper you cited: “Unlike these closed laboratory populations, populations in nature would often be open to emigration.” Evidence of group selection occurring or having occurred in real populations has never been observed.
Er, that isn’t right. See Wade’s flower beetles.
