| 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. |
| 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. |
| 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. |
| 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. |
