Obstructed labour is a leading cause of maternal and neonatal death and morbidity. It mainly results from a misfit between fetal head size and maternal pelvis. Traditionally attributed to a trade-off between selection for large-brained neonates and a biomechanically efficient, narrow pelvis for bipedal locomotion, this obstet-rical dilemma (OD) has recently been questioned in various ways. Yet, alternative hypotheses fail to explain the evolution of our complex birth mechanism, neurologically immature neonates, and our marked pelvic sexual dimorphism compared to other primates. Here, I propose 3 subprojects to advance our understanding of the OD: (1) I aim to restore a comprehensive evolutionary series of fossil hominin pelves in an objective way using state-of-the-art virtual image and ge-ometric morphometric methods since an evolutionary approach to the OD was so far complicated by often conflicting reconstructions of the same specimens. (2) I explore the hypothesis that pelvic sexual dimorphism increased during human evolution in concert with encephalization. Thus, our reconstructions will for the first time allow assessment of sexual pelvic dimorphism in early hominins while the degree of sexual dimorphism would provide an indirect measure for cephalo-pelvic disproportion. (3) Novel finite-element simulations of the birth process in fossil hominins allow taking into account the complex 3D shape of both the birth canal and the fetus as well as the dynamic nature of the birth process with ligamentous laxity, moulding of the fetal head and interference with the soft-tissue. Our innovative approach constitutes a major progress to previous studies that usually compared a few 2D measurements of the pelvis and fetal head. Assessing both the passageway and passenger in its full 3D shape is indispensable to predict the origins and evolutionary implications of obstructed labour. Further, our results are fundamental for future biomechanical analyses of hominin locomotion.
