dc.description.abstractObjectives: Understanding thoraco‐pelvic integration in Homo sapiens and their closest living relatives (genus Pan) is of great importance within the context of human body shape evolution. However, studies assessing thoraco‐pelvic covariation across Hominoidea species are scarce, although recent research would suggest shared covariation patterns in humans and chimpanzees but also species‐specific features, with sexual dimorphism and allometry influencing thoraco‐pelvic covariation in these taxa differently. Material and Methods: N = 30 adult H. sapiens and N = 10 adult Pan troglodytes torso 3D models were analyzed using 3D geometric morphometrics and linear measurements. Effects of sexual dimorphism and allometry on thoraco‐pelvic covariation were assessed via regression analyses, and patterns of thoraco‐pelvic covariation in humans and chimpanzees were computed via Two‐Block Partial Least Squares analyses. Results: Results confirm the existence of common aspects of thoraco‐pelvic covariation in humans and chimpanzees, and also species‐specific covariation in H. sapiens that is strongly influenced by sexual dimorphism and allometry. Species‐specific covariation patterns in chimpanzees could not be confirmed because of the small sample size, but metrics point to a correspondence between the most caudal ribs and iliac crest morphology that would be irrespective of sex. Conclusions This study suggests that humans and chimpanzees share common aspects of thoraco‐pelvic covariation but might differ in others. In humans, torso integration is strongly influenced by sexual dimorphism and allometry, whilst in chimpanzees it may not be. This study also highlights the importance not only of torso widths but also of torso depths when describing patterns of thoraco‐pelvic covariation in primates. Larger samples are necessary to support these interpretations.es_ES
