An international research network on bipedalism

Among primates, hominins represent the sole clade in which bipedalism is the main positional mode of posture and locomotion. Bipedalism is thus widely recognized as a key trait facilitating their adaptive success.

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Hominin musical sound production: palaeoecological contexts and self domestication

Anthropological Review
In this article we seek to integrate theories of music origins and dance with hominin fossil anatomy and the paleoecological contexts of hominin evolution.

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

The Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

The mechanism of labor in nonhuman primates: A look inside

The Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Postcranial evidence of late Miocene hominin bipedalism in Chad

, 2022
International audienceBipedal locomotion is one of the key adaptations that define the hominin clade. Evidence of bipedalism is known from postcranial remains of late Miocene hominins as early as 6 million years ago (Ma) in eastern Africa1,2,3,4 ...

PRIMATES, HOMINIDS, AND HUMANS—FROM SPECIES SPECIFICITY TO HUMAN UNIQUENESS? A RESPONSE TO BARBARA J. KING, GREGORY R. PETERSON, WESLEY J. WILDMAN, AND NANCY R. HOWELL

Zygon, 2008
In this response to essays by Barbara J. King, Gregory R. Peterson, Wesley J. Wildman, and Nancy R. Howell, I present arguments to counter some of the exciting and challenging questions from my colleagues.

The pelvis doesn't walk by itself: Wider pelves reduce the cost of walking over unstable surfaces

The Anatomical Record, EarlyView.
Abstract Walking over variable and/or unstable terrain is a key aspect of daily life and was crucial to the evolution of bipedalism. The ability to find gait solutions that maintained stability over uneven terrain for the least increase in metabolic cost was likely a hallmark of locomotor effectiveness in early humans, in particular acting as an ...

Dynamic finite-element simulations reveal early origin of complex human birth pattern

Communications Biology, 2022
Using finite element models of australopithecine pelvis reconstructions the secondary altricial nature of early hominin newborns is revealed, indicating that the need for cooperative breeding evolved secondary to bipedalism and thus prior to the ...

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

The Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.
