Curved backbone is unique to humans and helps the human being to walk upright. The lower curved portion of vertebral column absorbs shocks while walking. Vertebral column supports about half of the weight of the body.

Why have humans evolved stand upright?

According to this theory, the energy saved by walking upright gave our ancient ancestors an evolutionary advantage over other apes by reducing the costs of foraging for food. The idea is just one of many scientists have entertained as reasons for why humans walk on two legs.

What are some theories on why we walk upright?

Fossils show that some ancient humans developed longer legs, different hip structures or thicker leg bones, consistent with modern-day humans. These adaptations made upright walking easier and lessened the amount of energy required to walk upright.

Do humans have upright erect posture?

evolution. All primates sit upright. Many stand upright without supporting their body weight by their arms, and some, especially the apes, actually walk upright for short periods. The view that the possession of uprightness is a solely human attribute is untenable; humans are merely the one species of the…

The wide area of bone just below this the knee joint in Australopithecus anamensis is a result of that stress. It provides strong evidence that this individual walked upright. Fossils from around this time period come from early human species that lived near open areas and dense woods.

Why did humans evolve to be able to walk upright?

The primary one is that this ability eventually freed the hands for many tasks. Which means task enacting may have caused human evolution to move in a more upright motile direction. Humans that were able to walk upright more often proved more successful at task achievement and thus more successful at survival.
