I didn't get the metaphor of genetic structure (didn't seem particularly insightful), but the idea of collective intelligence seemed interesting. Groups are "smarter" that smart individuals even when there are no very smart individuals in them. Groups that performed better in certain tasks had caring people in them:
Group intelligence is correlated, Malone and his colleagues found, with the average social sensitivity — the openness, and receptiveness, to others — of a group’s constituents. The emotional intelligence of group members, in other words, serves the cognitive intelligence of the group overall.
