Let me conclude by saying that nothing I've written here means that the gluteus
maximus evolved exclusively for endurance running.
al. (2006) claim that the human gluteus
maximus evolved its shape and size due to endurance running.
Not exact matches
Functional morphologist Brigitte Demes, at the State University of New York at Stony Brook, notes that the gluteus
maximus is absolutely essential for rising from a squatting posture at rest or during foraging, so it might not have
evolved just for running.
Equally, it has been suggested that it the gluteus
maximus has
evolved in conjunction with the need for greater posterior tilt, which appears to be beneficial in energy conservation when standing, walking and running (see review by Hogervorst et al. 2009; Lee et al. 2014a; Eng et al. 2015a).
As a result, we've
evolved big, bulky muscle groups to help keep them stable, including the infamous gluteus
maximus, primary mover in hip extension, and gluteus medius and minimus, primary movers in hip abduction.
