How Cooperation Can Evolve in a Cheater's World<snip>
Whether you're a free-loading virus or a meat-stealing monkey,
selfishness pays. So how could cooperators survive in a cheater's
world? Thomas Flatt, a postdoctoral research associate at Brown, was
part of a group that created a theoretical model that neatly solves
this dilemma, which has stumped evolutionary biologists and social
scientists for decades. The trick: Keep the altruists in small groups,
away from the swindling horde, where they multiply and migrate.
Isn't this absolutely bog standard group selection? Small groups
with highly restricted gene flow between groups. Doesn't sound
like anything new at all!
I didn't notice where it said that gene flow between groups is
highly restricted. In fact, there seems to be an emphasis on migration
rather than group fission as the mode by which successful groups
come to dominate the population.
Good old 'bog standard' group selection doesn't work. They claim this
works. Seems to be pretty much the same as 'trait group selection'.
