There are two different suborders of primates such as strepsirrhini and haplorrhini. All non-human primates are divided by these two suborders; in other words, primates with having moist nose are strepsirrhini, and primates with dry nose are haplorrhini. In modern day, lots of primates still exist in specific regions. For instance, ring-tailed lemur is one of non-human primates from strepsirrhini, and chimpanzee is one of primates from haplorrhini. Because of living in different environment, these two primates have different characteristics and specific social group they involved. There are also many studies are being done with these primates. In addition, even though these two types of primates have lived in different region and different environment, they also have similarities between their environments. Unfortunately, one of their similarities is that a number of their species is dramatically decreasing by several factors such as primate hunters and loss of habitat. Through this paper, it mainly explains about how these two primates, ring-tailed lemur and chimpanzee, are threatened and additional information about their distinct characteristics.
Non-human primates are categorized and researched by primatologists who study both living and extinct primates in their natural habitats and in laboratories by conducting field studies and experiments in order to understand aspects of their evolution and behavior. Among lots of primates, ring-tailed lemurs are one of the most clearly identifiable primates due to their long, vividly striped, black and white tail. (Sauther 120). Through a research, called The Socioecology of the Ringtailed Lemur: Thirty-Five Years of Research, about ring-tailed lemur, it gives brief ideas about how lemurs look like and what specific characteristics they have. First, most of lemurs are located in the African island of Madagascar and some tiny neighboring islands. This region is extremely significant to primatologists because there are not only lemurs but also many amazing animals, found only in Madagascar but nowhere else in the Earth. Research also indicates that lemurs use their two hands and two feet to move through the trees without using their tails. One specific characteristic ring-tailed lemurs have is that they spend their primary time on the ground when other typed lemurs spend their most of time on the trees. (National Geographic) In addition, their eating habitat is also one of main characteristics because it is significant factor of their existence. One of the major food for them is fruit, which makes up the greater part of their diet, but also eat leaves, flowers, tree bark, and sap. Moreover, ring-tailed lemurs use their remarkable odor to communicate with others, and also they use their odor as a kind of weapon to protect from other species. In
their social group, they usually live in groups as troops gathering with 6 to 30 animals. (National Geographic). Both male and female lemurs live in troops, but a dominant female presides over all.
Chimpanzees are an example of haplorrhini of suborder. According to Los Angeles Times, they have interesting fact that they are the closest living relatives with human by sharing more than 98 percent of human’s genetic blueprint. Therefore, scientists and primatologists still study about relationship between human and chimpanzee to figure out how they are close each other, and they may think that human and chimpanzees share same ancestors approximately four to eight million years ago. (National Geographic). As looking at chimpanzees’ living arrangement, they live in social group with almost fifteen of them, and they are acclimatized with environment such as African rain forests, woodlands, and grasslands. Another characteristic that chimpanzees have is that they usually walk on two hands and two legs which call as knuckle...
