| They concluded that movement by the protohominids into this novel dimension of behavior was importantly linked with the advent of bipedalism. |
|
| One of the pleasures of Stanford's book is its splendidly gossipy account of recent research into the early history of hominid bipedalism. |
|
| An opposing camp argues that bipedalism is simply the most energy-efficient way for a hominid to get around on a flat surface. |
|
| Unfortunately, determining whether bipedalism was the cause of increased velocity, or simply a behavioral by-product, is difficult, as bipedality increased with stride number. |
|
| It therefore sheds light on a longstanding debate: whether it was bipedalism or giving birth to babies with large heads that drove changes in the shape of the human pelvis. |
|
| The most straightforward definition of species relies on morphology and related features: a species is a group of organisms with certain common features, such as hairlessness, bipedalism, and rationality. |
|
| Depending on which of these hypotheses is correct, the hominin lineage shifted from knuckle-walking to bipedalism or from quadrumanous climbing to bipedalism. |
|
| Primate locomotion can be classified on behavioral grounds into four major types: vertical clinging and leaping, quadrupedalism, brachiation, and bipedalism. |
|
| Vertical clinging and leaping, for instance, is primarily a function of the hind limbs, as is bipedalism, whereas brachiation is performed exclusively with the forelimbs. |
|
| The primates in this region have acquired bipedalism as a result of geological changes, resulting in a change of vegetation which became more sparse. |
|
| This process involved the gradual development of traits such as human bipedalism and language. |
|
| The comparatively minor anatomical differences between humans and chimpanzees are a result of human bipedalism. |
|
| Apart from bipedalism, humans differ from chimpanzees mostly in smelling, hearing, digesting proteins, brain size, and the ability of language. |
|
| The brains of these early hominins were about the same size as that of a chimpanzee, and their main adaptation was bipedalism as an adaptation to terrestrial living. |
|
| The earliest hominin, of presumably primitive bipedalism, is considered to be either Sahelanthropus or Orrorin, both of which arose some 6 to 7 million years ago. |
|
| There are several theories of the adaptation value of bipedalism. |
|
| They went out and looked at modern humans who, like Lucy, have feet adapted to terrestrial bipedalism, and found these people can still function as effective treeclimbers. |
|
| As a consequence of bipedalism, human females have narrower birth canals. |
|
| Bipedalism is the basic adaption of the hominin line, and it is considered the main cause behind a suite of skeletal changes shared by all bipedal hominins. |
