Evolution of bipedality in humans essay

On the basis of this model, bipedalism causes an increase in gaining of heat and facilitating the dispelling of heat. In the former model, Dryopithecus is ancestral to Pan and Gorilla. Another theory that lacked merit in this regard at the time was the Mosaic theory.

This was demonstrated most impressively in with the finding of Lucya nearly complete australopithecine skeleton. Fortunately for paleoanthropologists, some bones show dramatic signs of how a given hominin carried itself, and the adaptation to obligate terrestrial bipedalism led to notable anatomic differences between hominins and great apes.

Behaviour and morphology associated with locomotion also responded to the shift from arboreal to terrestrial life. Savannah and Mosaic Theories The very first endeavor of trying to elucidate the aspect of evolution was by Darwin through the Savannah theory. Third, they utilize their forelimbs for other purposes aside from locomotion.

Contact our live support team for any assistance or inquiry. As a result, the ape progressively developed and adapted a bipedal posture so as to permit its forelimbs to be utilized for exercising primitive weapons like stones as well as sticks.

In more recent decades, anthropologists have determined that bipedalism has very ancient roots. Bipedalism separated the first hominids from the rest of the four-legged apes.

Becoming Human: The Evolution of Walking Upright

In a phylogenetic model that emphasizes African Miocene species, Samburupithecus is ancestral to Australopithecus, Paranthropus, and Orrorin, and Orrorin begets Australopithecus afarensis, which is ancestral to Homo.

This showed that the offspring shall survive longer, shall be stronger and shall have a better reproductive rate than its parents had. This means that the early man did not have just one mate but several and in different areas thus a system known as a polygynous mating system.

The upright alignment of hominids is also significant in making the most of being directly exposed to sunlight in the course of the day, a period when the energy arising from sunshine is most powerful and forceful Wheeler, Journal of Human Evolution, 26 3But large cats, dogs, and hyenas also flourished in the new environments; they not only would provide meat for scavenging hominins but also would compete with and probably prey upon them.

Just like the carnivores, man evolved from a semi-quadruped mammal to a bipedal mammal due to his development over time from his feeding lifestyle Schmitt, The development of the bipedal locomotion and an upright posture by the early hominids was critical for their survival since they used their fore limbs to search for food.

Human Evolution and Its Link to Bipedalism&nbspEssay

Bipedalism is a capacity, mostly associated to humans, to use two legs in locomotion. Its origin has been given importance and served as a topic of long debate among experts due to the possibility that this form of locomotion gave way for the development of modern human characteristics.

Human evolution

Humans can perform all these movements by virtue of them being bipeds. There are several hypotheses of how and why humans developed to become bipeds according to the evolution theory some of which shall be discussed in this essay.
