For many years, numerous individuals including anthropologists have attempted to explain how a single species evolved into another. From the time of Charles Darwin to Creationism, anthropologists have established that chimpanzees are human’s closet relative. Furthermore, with the extensive voluminous amount of information, not only are chimpanzees genetically and evolutionary similar to human but share analogous traits. For instance, chimpanzees like human make and utilized tools in various techniques. Another trait shared is eutheria, where offspring depend on the placenta and grown internally of their paternities. In addition to the highly mobile digits that assist chimpanzees in grasping and climbing. These illustrations are just a few. This paper is twofold; to highlight humans and chimpanzees shared traits that can aid in recreating the past of humans, secondly to heighten my knowledge of the evolution of humankind and chimpanzees. Human are classified in the primate order. The primate order contains countless species of prosimians, monkeys, apes, and us. Moreover even though humans are classified along with other primates the nearest relative is chimpanzees. Similarly, humans and chimpanzees share, “anatomy, and genetic material” that has been noted for several years now. By sharing similar traits it is noted as a vital part of human evolution. Human evolution is the development of humans also known as Homo sapiens. Homo sapiens are categorized in the Hominidae family, a family that has shown to ensure increased brain size with complexity and bipedalism. Chimpanzees have undergone many different changes during that resulted in binocular vision, mobile digits without claws but nails, decreasing in sense of smell due to a reduced snout, large and complex brains. Specific traits are illustrated distinctively within humans (Kottak, 2009). The first trait chimpanzees share with humans is grooming. Grooming is the action of cleaning oneself or another. The purpose of grooming among primates has many functions. The first is to clean another while the other is is sharing a bonding experience with a partner or friend. Both primates experience, “friendless, submission, appeasement or closeness… embracing, touching, and jumping up and down.” These behaviors assist in shaping closeness between the two chimpanzees taking part in grooming (Haviland, Prins, Walrath, & McBride, 2005). Two chimpanzees sit face to face with each other and perform these procedures. Chimpanzees use their digits to “remove parasites or detritus from another’s hairy body surface,” resulting in the consumption of parasites There are different grooming habits among chimpanzees. For instance, some chimpanzees groom each other face to face while other chimpanzee let the one being groomed to move about as they feel. Some chimpanzees use sticks, or leaves as tools for grooming. In humans grooming is also used as a bonding experience for example between mother and child (McGrew, 1998). The second trait is the increase in the size of the brain and complexity. Primates have the highest intelligences. The size and complexity of brain enables primates to retain additional information to utilize in tool making or climbing. The advantages of a large brain with complexity assist in “navigat[ing]…find[ing] food in a highly complex environment.” The brain size of chimpanzees is larger than most other mammals (Kottak 2006; Stanford, Allen, Anton, 2006). The third trait is highly mobile digits. In humans mobile digits are hands. Chimpanzee’s highly mobile digit allows them to grasp items and climb trees more efficiently. Chimpanzees like human have five fingers on both digits (hands and toes). Primates also have opposable thumbs and tactile pads. Tactile pads empower chimps to have great sensitivity to what they come into contact with. The tactile pads are...
