Partner Choice / Partner Selection and Rejection:

Randolph M. Nesse:

>"Social selection" is not an ideal term because it has different meanings in different fields. "Partner choice" is closer to the core idea, but choosing partners is only part of the story; rejecting or punishing partners is also important. "Partner selection and rejection" captures the essence of an evolutionary process that made us capable of goodness. People with tendencies to help their friends generously are preferred as social partners, so they get the best partners and all the attendant fitness advantages. This process may have been crucial for making humans extraordinarily cooperative and capable of creating culture.<
