Did Energy Costs of Walking Limit the Evolution of a Larger Human Birth Canal?

Abstract excerpt

Energetic disadvantages of a wider pelvis have long been central to explanations of the small human birth canal and the relatively risky birth process, iconic for antagonistic selection in evolution. While static mechanics predict such effects, recent empirical studies question this view. By altering a generic musculoskeletal model beyond modern human variation one parameter at a time and applying predictive forwa...
