The major emphasis of the journal is on evolutionary approaches to cognition, reflecting the fact that the cognitive capacities of organisms result from biological evolution. Empirical and theoretical work from both fields, evolutionary and cognitive science, is accept- ed, but particular attention is paid to interdisciplinary perspectives on the mutual relationship between evolutionary and cognitive processes. Submissions dealing with the significance of cognitive research for the theories of biological and sociocultural evolution are also welcome. “Evolution and Cognition” publishes both original papers and review arti- cles.
