Chimpanzee versus Humans: Similarities & Differences


Since the first days of human thought into their beginnings, chimpanzees


have played a vital role in showing who we were. The chimpanzee, one of the


great apes, makes it home in the forests of Central and West Africa. Their long


arms and legs adapt them for living in such regions as lowland jungles and


mountainous regions. Humans are classified in the order Primates, and family


Hominade. Within this family, human beings, our nearest living relatives, the


African apes, are also placed. Though in some classification standards, apes


are placed in the family Pongidae.


The defining characteristic of Hominids is their ability to walk


bipedally, using two feet and walking upright. This form of movement lead to


many adaptations within the Hominids skeleton. There are notable changes in the


spinal cord, pelvis bone and legs. The chimpanzee does have the ability to walk


upright and does, but it spends most of the time walking on four limbs. It uses


it?s arms as it?s front legs and walks on it?s knuckles. Our brain capacity is


about twice as large as that of the chimp. Humans have a brain capacity of 1300


to 1500 cc, while the chimps are about 600 – 800 cc. It is though by scientists


that our brain size grew over time as were evolved into making complex tools and


we became increasingly sophisticated. The human skull is slightly different


from that of our primate ancestors, these changes occurred over thousands of


y

ears of evolution. Over time the humans skull and teeth have decreased from


that of our ancestors. The chimp has much larger canine teeth and a protruding


jaw line. A similarities though can be seen on how uniform the layout of teeth


are between the humans and chimps, both possess canines, premolars, and molars.


Other notable similarities between us and the primates, specifically the


chimps is the use of an opposable digit, a thumb. The thumb allows for grasping


tools and food. This proves to be a vital asset when chimps go out hunting for


prey. Chimps also resemble humans socially and in their actions. After Jane


Goodall showed the world what chimps were like, we saw that they act like us.


The chimps stay together in packs ranging from two to fifty. The men guard and


protect the pack from rival packs. In their hunting technique they were seen


pushing the prey into a trap, something very smart on their part. All this


sounds very much human-like, but then they also were seen making tools. Chimps


used basic tools and twigs to catch ants and eat them. They used a rock to


smash nuts. How this is learned is a mystery, many think it is passed down


through lineage. Chimps do lack forethought, which is thinking ahead and doing


something. The chimpanzee and human differences and similarities is very eye-


opening, especially to someone who is seeing most of this information for the


first time. Although I believe that their is a lot to prove I do think our


direct ancestors were the primates and there should be a lot of research to


prove even more similarities.
