The concept you are both approaching anon_giraffe from the perspective of reproducing intellectual structures and tvbcof from the idea of social evolution is the that of group selection.
Group selection is a very deep and mostly under-explored area of evolutionary biology. The most intriguing and active thinking that I have seen in this area is that of Charlton. Below is an excerpt of his work.

General properties of Group Selection and the 'group mind' (in relation to the adaptive production of geniuses)
Selection in this sense suggests that randomness exists.
Random cannot exist in a system where cause and effect exist.
Cause and effect are upheld by Newton's 3rd Law, which is universal to our knowledge, and which has never been found to have any failure in anything.
Random as far as the way people use it, is simply an organized method of guessing, called probability, that people use. They use it because they have such limited ability for determining the abundant, detailed activities of cause and effect.
Quantum Mechanics is a complex form of complex probability that is used to guess more complex things.
QM doesn't prove anything.
The idea of "selection" suggests that there is intelligence doing the selecting.
