Brazilian Archives of Biology and Technology, 2015 This article aimed to review various theories of bipedalism and provide a holistic answer to human evolution. There have been two questions regarding bipedalism: i) why were the earliest hominins partially bipedal?, and ii) why did hominins become ...

Human, almost human: how many human species are there?
Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2022 The debate on the question "How many human species are there?" may never be resolved. Leaving aside the theological and political aspects of the question, this paper analyses three dimensions of the problem – metaphysical, biological and technical ...

Safe Carrying of Heavy Infants Together With Hair Properties Explain Human Evolution
Frontiers in Psychology, 2022 As a physicist, my scientific career was interrupted by maternity, and afterward retaken, with a parallel independent personal perspective on human evolution. My previous published contributions are reanalyzed as Hypothesis and Theory.

Simulating the evolution of bipedalism and the absence of static bipedal hexapods
Bioinspiration & Biomimetics, 2021 Abstract In nature, very few animals locomote on two legs. Static bipedalism can be found in four limbed and five limbed animals like dogs, cats, birds, monkeys and kangaroos, but it cannot be seen in hexapods or other multi-limbed animals.

Variability and the form–function framework in evolutionary biomechanics and human locomotion
Evolutionary Human Sciences, 2022 The form–function conceptual framework, which assumes a strong relationship between the structure of a particular trait and its function, has been crucial for understanding morphological variation and locomotion among extant and fossil species across ...

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.

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 ...

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.
