Fossil evidence for bipedal evolution in the human clade. Although emphasis on the likely ancestral locomotor mode of hominins and on the transformation of the ape foot into a human foot may have changed over the years, there is still no current consensus on these issues and there is unlikely to be one in the near future.

2010年8月17日 · As we will see below, current evidence points to bipedalism occurring very early in the fossil record (Zollikofer et al. 2005; Senut et al. 2001; Lovejoy et al. 2009a), so features relating to that are certainly important.

2022年11月1日 · We now know that various hominin species living in different environments throughout Africa, sometimes contemporaneously, evolved different ways to walk on two legs. The emergence of bipedalism...

2025年1月7日 · Twentieth-century theories proposed a wide array of other factors that might have driven the evolution of hominin bipedalism: carrying objects, wading to forage aquatic foods and to avoid shoreline predators, vigilantly standing in tall grass, presenting phallic or other sexual display, following migrant herds on the savanna, and conserving ...

2023年8月1日 · Abundant fossil discoveries document morphological adaptation in evolution and new techniques have been developed to reconstruct locomotor biomechanics of fossil forms. In this Perspective, we review the temporal changes in our understanding of the origins of human bipedal walking.

2012年8月6日 · In the 1930s and 1940s, further fossil discoveries of bipedal apes that predated Neanderthals and H. erectus (collectively called australopithecines) helped convince anthropologists that...

2024年10月17日 · The journey to understanding bipedalism begins with the fossil record, revealing the transition from quadrupedal ancestors to upright walkers. One of the earliest known hominins, Sahelanthropus tchadensis, dating back approximately seven million years, exhibits features suggesting a shift towards bipedal locomotion.

2024年10月27日 · Fossil evidence provides insights into this transition. One of the earliest known bipedal ancestors, Sahelanthropus tchadensis, exhibited a mix of primitive and advanced traits, suggesting a gradual shift towards upright walking. The position of the foramen magnum, the hole in the skull where the spinal cord passes, indicates a more vertical ...

2000年3月23日 · Fossil evidence demonstrates that by 4.1 million years ago 1, and perhaps earlier 2, hominids exhibited adaptations to bipedal walking.

1985年11月1日 · The fossil evidence reveals that the primitive hominoid pattern for positional behavior, as best represented by Proconsul, is that of a generalized quadruped, capable of pronograde quadrupedalism and of some climbing. Specialized behavior, including cursorialism, leaping, brachiation, and substantial suspension, may be ruled out.
