More seriously: one of the major struggles of society is setting up incentive structures that align the interests of the individual with that of the group, so even people acting in their own self interest still contribute to the greater whole. We only managed to go to the moon because we managed to turn an utterly selfish ideological struggle into a space race.

This applies for cooperation as well. As soon as you have such an organization the people inside that have the same intensive problem. This equally results in the cooperation itself not being rational.
What forms of cooperation works depends again on how to align interest of the people inside them.

There's no reason dinosaurs couldn't have written better poetry than any creature since.

I very much doubt that either is capable of emulating the other in real time.
