So what do we think everyone, is this just a very unique, possibly mutated gorilla or is this another step in evolution taking it’s toll on this special ape? However, habitual bipedalism may have favored modifications of the hip to allow a more orthograde posture, and of the hind limb abductor mechanisms to efficiently exert mediolateral ground forces. Locomotion and posture from the common hominoid ancestor to fully modern hominins, with special reference to the last common panin/hominin ancestor.

Over the last decade, there have been a number of important fossil discoveries in Africa of what may be very early transitional hominins, or proto-hominins. Notable differences include hip and trunk angles, which reflected a more orthograde trunk posture during bipedalism, and mediolateral ground reaction forces, which were larger during bipedal walking.

But they are defined by the locomotion that they use most often. 1M-XF. Evol Anthropol. This link pertains to this class because it is involving one of our distant ancestors and something that doesn’t usually pertain to this group: bipedalism, a major milestone for hominids that developed millions of years ago.

One of the proposed mechanisms was the knuckle-walking hypothesis, which states that human ancestors used quadrupedal locomotion on the savanna, as evidenced by morphological characteristics found in Australopithecus anamensis and Australopithecus afarensis forelimbs, and that it is less parsimonious to assume that knuckle walking developed twice in genera Pan and Gorilla instead of … English.
