New fossils of Australopithecus sediba reveal a nearly complete lower back
eLife, 2021 Adaptations of the lower back to bipedalism are frequently discussed but infrequently demonstrated in early fossil hominins. Newly discovered lumbar vertebrae contribute to a near-complete lower back of Malapa Hominin 2 (MH2), offering additional ...

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.

Forelimb muscle and joint actions in Archosauria: insights from Crocodylus johnstoni (Pseudosuchia) and Mussaurus patagonicus (Sauropodomorpha) [PDF]
, 2017 Many of the major locomotor transitions during the evolution of Archosauria, the lineage including crocodiles and birds as well as extinct Dinosauria, were shifts from quadrupedalism to bipedalism (and vice versa).

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.

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 ...

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.

Muscle endurance: Is bipedalism the cause?
Frontiers in Ecology and Evolution, 2022 One may ask if the transition to bipedalism from the condition of quadrupedalism, which occurred about 7 million years ago, has been the cause or consequence of a series of fundamental physiological muscular aspects including the cost of locomotion, a ...

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.
