Efficient long distance locomotion. 2011, pg. Being upright also makes it easier to reach up into trees for food (with the hands or the mouth) and it frees up the hands to hold and carry things. Hominid bipedalism has evolved as a product of natural selection, a theory coined by Charles Darwin in 1859. Limited and exclusive bipedalism can offer a species several advantages. This change from quadrupedalism was the most significant adaptation that ever happened to these early hominids. And these are disadvantages that we live through or are going to live through thanks to the thing that helped keep our species alive. Disorders of the feet and spine are also common, including scoliosis (Gorman and Breden, 2009), Scheurmann kyphosis (Farrell et al., 2012) and other claudications in the lower extremities (Smith, 1990). Bipedalism also reduces exposure to the sun, keeping the body cooler. They have been a common point of, A significantly enlarged brain size is one of the main features distinguishing modern humans from other hominids. According to Professor Spencer-Wood, bipedalism is an efficient means of covering long distances given that there is less waste of energy when walking. However, the fossil evidence has revealed that an increased brain size evolved only after the evolution of bipedalism early in the human lineage (Alexander et al., 1986; Ashby et al., 2010). Bipedalism therefore offers a great survival opportunity. 3) It allowed our ancestors to see over the tall grasses. Bipedalism, a major type of locomotion, involving movement on two feet.

Animals that walk upright on two legs either some the time or all the time have several advantages over those who do not. This theory provides a major, proximate pre-adaptive cause for the later adoption of bipedalism by proposing the use of an existing behaviour in a new environmental context, namely increased use of, and deference to bipedal displays to mitigate violence and make possible the equitable allocation of scarce resources. Humans are unrivalled in both their cognitive and linguistic capabilities, and since an expanded brain appears to be correlated with intelligence (Darwin, 1871), it is not surprising that the evolution of modern humans was believed to be the result of increased.

When walking on the ground, a bird uses its legs to hop around. Results were determined through human, developments over millions of years. Also, what advantage did the development of bipedalism most likely confer to early hominids? In Wikipedia. (Haviland et al. 4) It allows us to travel long distances. This posture raises the head higher up which gives the animals a wider field of view to look for prey and keep an eye out for predators. • For millions of years, primates were highly successful as full-time arboreal creatures (many still are) • And, a whole line of Old World monkeys and most of the Great apes adapted the anatomy of arboreal life to the ground without major structural changes Bipedalism allowed hominids to free their arms completely, enabling them to make and use tools efficiently, stretch for fruit in trees and use their hands for social display and communication. While the skeletal structure of primates allows them to stand on their hind legs for short periods, the ability to stand on two legs provided many advantages for early hominids. These hominids were moving out of the forest and beginning to walk upright, out on the open plains (Fagan, 98). Bipedalism is a form of locomotion that is on two feet and is the one factor that separates humans from other forms of hominoids.

Bone and joint disorders such as osteoporosis and osteoarthritis are associated with bipedalism (Cotter et al., 2011; Pennisi, 2012). Despite these advantages, bipedalism also has considerable disadvantages. The image above shows the earliest human ancestor Australopithecus afarensis who was fully bipedal.
