Forest terrains influence walking kinematics among indigenous Tsimane of the Bolivian Amazon
Evolutionary Human Sciences, 2022 Laboratory-based studies indicate that a major evolutionary advantage of bipedalism is enabling humans to walk with relatively low energy expenditure.

Bringing trees back into the human evolutionary story: recent evidence from extant great apes
Communicative & Integrative Biology, 2023 Hypotheses have historically linked the emergence and evolution of defining human characteristics such as bipedal walking to ground-dwelling, envisioning our earliest ancestors as living in treeless savannahs (i.e.

The impact of footwear on human talar trabecular architecture. [PDF]
J AnatMedial and lateral views of the human foot skeleton in the shod and unshod groups, with color maps representing mean relative trabecular bone volume fraction (rBV/TV) in the talus for each group. The shod group exhibited greater rBV/TV in the medial and posterior talus, whereas the unshod group had greater rBV/TV in the talar head and neck.

Laetoli footprints preserve earliest direct evidence of human-like bipedal biomechanics.
PLoS ONE, 2010 BackgroundDebates over the evolution of hominin bipedalism, a defining human characteristic, revolve around whether early bipeds walked more like humans, with energetically efficient extended hind limbs, or more like apes with flexed hind limbs.

Humans are not unique: difficult birth is common in placental mammals. [PDF]
Biol Rev Camb Philos SocABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Predicting the metabolic energy costs of bipedalism using evolutionary robotics [PDF]
, 2003 To understand the evolution of bipedalism among the homnoids in an ecological context we need to be able to estimate theenerrgetic cost of locomotion in fossil forms.

Etude de cas : la bipédie des chimpanzés de la communauté de Sebitoli, Ouganda
Revue de Primatologie, 2022 To better understand the selective pressures associated with the emergence of bipedal behaviours in the human lineage, the study of bipedal behaviours and their context in modern chimpanzees (Pan troglodytes) provides some basis for comparison ...

Human calcaneal variation relative to subsistence strategy, activity level, and footwear
Frontiers in Earth Science, 2023 Lower limb cortical and trabecular bone varies with human behavior, leading to suggestions that activity level decreases have contributed to a more gracile skeleton.

African ape carpal morphology is not too specialized to represent the ancestral hominin carpus. [PDF]
J AnatKnuckle walking is one hypothesized behavior of the Pan‐Homo last common ancestor. We analyzed carpal morphology, including Euclidean distances between behavioral pairs, to investigate whether the carpals of knuckle‐walking taxa appear relatively specialized.

Royal Society Open Science, 2023 Birds and crocodylians are the only remaining members of Archosauria (ruling reptiles) and they exhibit major differences in posture and gait, which are polar opposites in terms of locomotor strategies.
