An Evolutionary Quantitative Genetic Analysis of the Impact of Cephalopelvic Disproportion on Cranial and Pelvic Co‐Evolution in Anthropoids

Sex-specific patterns of evolution support hypotheses that obstetric selection may have impacted multiple primate lineages. Although size may play a role, it does not appear to be the dominant factor in evolution for either element. This study highlights the usefulness of using methods from evolutionary quantitative genetics to test long-standing hypotheses by incorporating multiple skeletal elements simultaneously.
