The same phrase "survival of the fittest", which was so much misinterpreted, could be fixed by adding one extra word: group, family, clan, team, company or country. "Survival of the fittest family" or "fittest group" implies both competition and cooperation to an equal measure. But I love the shock value in "Survival of the friendliest". Good title, and good to drive this point again and again through the mind of the public.
