Two Major Theories Of Bipedalism

When the bipedalism for the evolution of the human line, there are many different hypothesis that have been made which have been refuted and there are many that is still plausible. That being said, there are two major theories behind the evolution for bipedalism that are most commonly referred to and these are Energy efficiency and Pair Bonding.
The traditional and the first theory of Bipedalism can be traced to Charles Darwin. Based on his observation, he asked the question of advantages of bipedalism versus quadrupeds. His reasoning behind bipedalism is according to Larsen (2016) is, to manufacture and use these tools; the early humans needed great intelligence. It was the hypothesis that has lasted until it was refuted after the discovery in scientific community that earliest known tool is 2.6 mya while the evidence of
Based on the anthropological evidence, it is shown that areas in which the first bipedal species did not live around patchy forested wooded area. Instead, there is evidence that suggests base on the fossil evidence; it used to be an area that was more of wet tropical climate. Another reason suggests according to Larsen the disadvantages of bipedalism is, (2016, 255), While standing upright gives better view of the surrounding, it also gives better views for the predators, and walking vertical with heavy object can cause back injury, and many others that gives more disadvantages than advantages. However, one cannot deny the Owen Lovejoy’s theory of pair bonding which is based on more objective reasoning behind bipedalism. When attempting to see reason behind evolution of bipedalism in early hominins, there are many different theories or hypothesis that can be plausible based on the evidence that have been collected so far. However, out of all the theories, Owen Lovejoy’s Pair Bonding theory is most plausible and have the most evidence that backs his
