Ever since the world was created, we as humans have evolved due to primate evolution. Each primate has developed different physical appearances over time. They were categorized as primates because they share many features such as: a bent vertical position, bendable limbs , hands and feet has high degree quality, maintaining of the 5 digits on hands and feet, function of the opposable thumb, they had nails instead of claws, lack of nutritional knowledge, color vision with outstanding awareness, their eyes are positioned in the front of their face, which caused visual information to be transmitted from each eye to both parts of the hemispheres of the brain, and they were also able to see 3d.

This caused the primates to want to learn behaviors, the ability to live in social groups, and to adapt to day/night time patterns. Due to the ecosystem undergoing different changes. Such as the continental drift, deforestation, natural disasters and, global warming which is still happening today. These changes caused primates to become less arboreal and more earthly. To survive the causes of natural selection, earthly life styles and other issues primates had to developed vertical locomotion, changes in body shape, growth in size and loss of hair. The world has gone through a lot of changes. However to adjust to these changes the primates had to adapt…show more content…
(Webster Dictionary) Most of the quadropedal primates are arboreal, like the bearded Saki and there are some earthly quadropedal primates like the savanna baboon. Normally, the limbs of earthly quadrupeds are the same length. In the arboreal quadrupeds forelimbs are shorter and may be as long as the rear limbs. Another form of motion primates’ use is brachiating. Webster Dictionary defines brachiating as the progress of swinging hold to hold by the arms. An example of a primate that uses brachiating is siamangs which is located in Southeast Asia. Primates that uses brachiating and leaping together is known as semi brachiates an example would be a spider monkey. These primates are mainly arboreal, and are categorized by arms that are longer then legs, short back bones long fingers and smaller thumbs. Also primates used a form of locomotion when a primate supports itself vertically by grasping onto tree trunks while their knees and ankles are flexed tightly which is known as vertical clinging and leaping ( Webster Dictionary) . These primates are categorized by their long back limbs, and long fingers. These primates are usually arboreal. Primates and mammals have certain characteristics like: body hair, long pregnancy and live birth, mammary glands, different types of teeth structures, the skill to maintain a certain body temperature, bigger brain size and a the
