Evolution of genomic imprinting in humans: Does bipedalism have a role? [PDF]
Recent studies have indicated that genomic imprinting is less conserved in human placenta and fetuses than in mice. Studies in mice confirm evolutionary predictions that imprinted genes have an important role in fetal growth via their effects on ...

Why Do Humans Exercise? A Neuro‐Evolutionary Framework for Discretionary Physical Effort
ABSTRACT Hominin evolution made physical activity obligatory for survival. Modern environments decoupled effort from ecological returns, generating an evolutionary mismatch that favors energy conservation over voluntary movement. This review distinguishes between subsistence‐based physical activity, the ancestral condition directly coupled to survival,

Traditionally, feet have had a bad reputation. This is reflected in certain popular expressions, but also in the hierarchy that has been established between the upper parts of the body (brain, mouth and larynx) and the lower part.

Early Hominin Movement Patterns at Laetoli, Northern Tanzania
The site of Laetoli in northern Tanzania is famous for its preservation of 3.66-million-year-old footprint trails, among which are several belonging to an upright walking hominin (Day and Wickens, 1980; Leakey and Hay, 1979; Masao et al., 2016; McNutt et

Effect of Stump Length on Postural Steadiness During Quiet Stance in Unilateral Trans-Tibial Amputee [PDF]
Although force platform based Center of pressure (COP) measures of postural steadiness have been used to test the diagnostic significance of various cerebellar and labyrinthine lesions, but very few literature are available on amputees.

Bipedalism, pelvic–spinal balance and cranial facial development [PDF]
The transition to human bipedalism and the verticalization process are essentially marked by the extension of the hip and the straightening of the trunk by sacral inclination and lumbar lordosis. These phenomena resemble those observed in children during

Savanna chimpanzees (Pan troglodytes verus) as a referential model for the evolution of habitual bipedalism in hominids [PDF]
Observations of the bipedal behavior of wild savanna chimpanzees (Pan troglodytes verus) can provide insight into the evolution of habitual bipedalism in early hominids.

ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Remain thou as thou art: The bargain of vegetabling
Abstract Vegetabling resulted in the development of a unique food source comprised of highly immature plant organs that delivers desirable textures, flavors, and nutritional diversity to human diets. In contrast to some dry‐seeded crops, perishable vegetables require enormous inputs of energy and technology during the postharvest period to preserve ...
