To understand the evolution of cognitive abilities, we need to understand both how selection acts upon them and their heritability. Recent work suggests that there are fitness consequences for free-li
Individual differences in cognitive performance can have genetic, social and environmental components. Most research on the heritability of cognitive traits comes from humans or captive non-human anim
