Primate and human brain evolution
With humans as the outlier, primates are an excellent model system for investigating the link between brain evolution and the evolution of cognition.

Mammalian brain evolution
Several mammalian clades have independently evolved higher cognition. Such instances of parallel and convergent evolution provide exceptional opportunities to disentangle the patterns and processes that shape brain evolution.

Vertebrate brain evolution
Because different classes of vertebrates display widely varying neural architecture, comparisons within and across different classes provide fundamental information on the basic principles of brain evolution.
