Large-scale phylogenetic studies of animal cognition have revealed robust links between absolute brain volume and species differences in executive function.
However, past comparative samples have been composed largely of primates, which are characterized by evolutionarily derived neural scaling rules.
Therefore, it is currently unknown whether positive associations between brain volume and executive function reflect a broad-scale evolutionary phenomenon, or alternatively, a unique consequence of primate brain evolution.
