Essay on human life cycle

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. The earliest bipedal hominin is considered to be either Sahelanthropus [39] or Orrorin , with Ardipithecus , a full bipedal, [40] coming somewhat later.

[ citation needed ] The early bipedals eventually evolved into the australopithecines and later the genus Homo .

It is possible that bipedalism was favored because it freed up the hands for reaching and carrying food, because it saved energy during locomotion, because it enabled long distance running and hunting, or as a strategy for avoiding hyperthermia by reducing the surface exposed to direct sun.
