Ecological not social factors explain brain size in cephalopods

The paper investigates factors influencing brain size in cephalopods, finding ecological factors, not social ones, are more strongly associated with larger brain sizes.

A phylogeny of extant coleoid cephalopods with brain data

The paper constructs a composite phylogenetic tree of extant coleoid cephalopods using existing phylogenetic data and brain measurements to support future studies on brain evolution.

Cultural Evolution of Genetic Heritability

This paper reconciles behavioral genetics and cultural evolution using a dual inheritance framework to show how cultural dynamics affect genetic heritability estimates and trait causality.

The Cultural Brain Hypothesis: How culture drives brain expansion, underlies sociality, and alters life history

The paper models the Cultural Brain Hypothesis and its extension, the Cumulative Cultural Brain Hypothesis, to explain brain expansion and its evolutionary implications.
