Group Selection Due To Differing ESSs
The problem with group selection is that for a whole group to get a single trait, it must spread through the whole group first by regular evolution. But, as J. L. Mackie suggested, when there are many different groups, each with a different Evolutionarily Stable Strategy (ESS), there is selection between the different ESSs, since some are worse than others. For example, a group where altruism arose would outcompete a group where every creature acted in its own interest (see, for instance, the ESSs created by Koinophilia).

Famous quotes containing the words group, selection, due and/or differing:
“Once it was a boat, quite wooden
and with no business, no salt water under it
and in need of some paint. It was no more
than a group of boards. But you hoisted her, rigged her.
She’s been elected.”
—Anne Sexton (1928–1974)
“It is the highest and most legitimate pride of an Englishman to have the letters M.P. written after his name. No selection from the alphabet, no doctorship, no fellowship, be it of ever so learned or royal a society, no knightship,—not though it be of the Garter,—confers so fair an honour.”
—Anthony Trollope (1815–1882)
“The resistance we make to our passions is due to their weakness, not our strength.”
—François, Duc De La Rochefoucauld (1613–1680)
“Journeys, like artists, are born and not made. A thousand differing circumstances contribute to them, few of them willed or determined by the will—whatever we may think.”
—Lawrence Durrell (1914–1991)
