the social reasons we are more unique than other animals. Opposable thumbs, along with our use of language and invention of technology are what make humans truly unique from all other species. The closest animal to the human race are primates. Chimpanzee’s and humans are 99 percent identical in terms of genetics, but where they differ are their thumbs. Doctor Prabhakar says, “Opposable thumbs, manual dexterity and ankle or foot adaptations for walking on two legs are hallmarks of our species” (Scientist
special kind of pharynx, mouth, and tongue that enable humans to speak vowels (Campbell 86). This makes us unique in that we can speak and no other animal can effectively. There are many other adaptations to the hands and vision that humans have experienced. Humans have very long opposable thumbs, and this gives us the ability to perform with two different types of grip (Campbell 82). First, the power grip is the one grip that every primate has; it requires the fingers to be able to fold inwards
and how humans share a common ancestor with fish through the theory of evolution. Throughout the text, examples of retrodiction are the imperfect adaptation of a panda’s thumb and gill slits in the beginning stages of a human embryo. Common ancestry is proven by the existence of fossils and these evidences proves that evolution is true. Imperfect adaptation is a fundamental element that makes up part of retrodiction. If a creature on earth is perfectly adapted to their ways of life, they would thrive
increasing either flexibility or sense perception. All primates have limber shoulders and hip joints to allow a great range of movement. Primates have five digits and opposable thumbs and big toes that allow them to grab food or hang on to branches. All of these adaptations were needed for an animal that lived in the trees. The opposable digits help primates hang onto trees, and the shoulders and hip joints provide flexibility for moving around in the trees. (“Classification Lab” Eukarya. Web. 29 Sept
Anthropology 115 The Evolution of Primate Locomotion and Body Configuration Primates first evolved from the trees of tropical forests, later to the ground. Through the times of promisians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes. The Earth has encountered several geological and climatic changes over time. For the primates existed at that time had to adjust itself especially in body configurations and locomotion in
Tamarins’ diets are omnivorous, feeding mostly on fruits but also eating insects, small reptiles or small mammals. Because they are so small it made them more difficult to observe through the cage wire but their small size can be used as an advantageous adaptation that they use to hide from predators. The last type of primate that I observed was an Old world monkey classified in the hominoids super family, which contains members of the primates that includes apes and humans. I observed a type of Ape known

Through the times of prosimians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes.

For the primates existed at that time had to adjust itself especially in body configurations and locomotion in order to better survive. It is important to be aware of this information
first evidence of hair. Its bones show pits in its skull around the cheeks where whiskers would have been. Thrinaxodon’s nocturnal lifestyle and its burrowing habits would have required more sensory assistance and whiskers would have been an ideal adaptation to this new climate. This creature is the first evidence of a half mammal half reptile. Another critical change in the transition from reptile to mammal is in the ear. Mammals have highly sensitive ears which are attributed to our three middle
platyrrhine noses where the nostrils have a septum and face the side. New World Monkeys make up this infraorder. They are strictly arboreal and have prehensile tails that they use to hang from branches and pick things up. Some have no thumb at all and others have a nonopposable thumb. They are split into two families, the Callitrichidae and the Cebidae. The Callitrichidae family includes marmosets and tamarins. Both of these species have modified claws except for their big toes. They are omnivorous and rely
relatives, apes and chimpanzees. This transition to bipedalism was facilitated by structural changes comprised of an angled thigh bone, a more sturdy and broad pelvis, a wider patella, an S-shaped spine, and long femurs. The compilation of all of these adaptations allowed hominids to not only support their entire body weight while standing upright, but efficiently take long strides, therefore allowing them to travel greater distances. Though much is known about the implications for the transition to bipedality
