This study shows that brain size reduction in dogs began in the Late Neolithic, 5,000 years ago, with a 46% decrease compared to prehistoric wolves.

The paper tests whether male social dominance influences female mate choice and access to mates in pygmy halfbeaks, finding dominance affects access but not female preference.

The paper investigates how habitat complexity affects sexual selection on brain size and ornamentation in pygmy halfbeaks, finding stronger selection for brain size in open environments.

This study shows female guppies preferentially mate with related males in complex social settings, challenging previous findings on inbreeding avoidance.

The paper tests the social brain hypothesis by showing that guppies with larger brains lose contests faster, suggesting brain size affects social competence in conflict resolution.
