Primate Facial Species

481 Words2 Pages

Near the junction between a single ancestral species branching off into two distinctive species, there will undoubtedly be large similarities between the two species. These similarities are expected to diminish over many generations as the two species become reproductively incompatible. However, If we consider the "grey area" that is the time between two strains of a species becoming reproductively distinct, we can why it is so advantageous for distinguishable facial features to arise; distinct facial features serve as a form of genetic authentication that allows identification of individuals with certain genes. These are the exact genotypic traits that must be propagated in a subset of the ancestral species for a budding new species to adapt to a new environment and/or escape the competition for resources from the original ancestral species by developing a niche. Hence, two characterizing features of primates with distinguishable facial features are genetic diversity and capacity for adaptive radiation.
Distinguishable facial features in primates can also be explained in terms of its role in driving the evolution of social complexity. As discussed in lecture, social interactions are a major driving factor behind primate intelligence. A social group that can correctly identify and …show more content…

The reliability is a consequence of being able to visualize the other member's physical identifiers besides their face as well as indicate the exact location of the other individual. Hence, it is clear to see that distinguishing facial features not only facilitate social growth and complexity; they also facilitate the evolution of the visual faculties. Since visual processing comprises one of the most brain-intensive biological functions1, distinguishable facial features should characterize primates with larger

Ancestors in Our Genome, addresses the continuingly advancing disagreement upon whom our closest ancestor is within the great apes, described as the hominoid trichotomy debate. The author, Eugene E. Harris examines many different sources of evidence within the book, and with the help of improvements in biological and DNA technology he helps discover who our closest ancestors were. Also when we were first separated from them and how the separation took place. Although there have been many recent advances in technology, a large number of unanswered questions are still a mystery within our genome and evolution from the great apes. Chapter one discusses the debate of morphology - studying fossil evidence of the great apes - versus molecular

Harry S. Truman’s idea to drop the atomic bomb during World War II was a bad idea, it caused around 210,000 people to die and many of parts of their land and buildings were destroyed or ruined, it also had the scientists who made the bomb, ask the president to not use the weapon they had created and caused many after radiation effects. The after-effect of Harry S. Tuman’s plan to drop the atomic bomb was a bad idea because it caused the death of 210,000 people in only two bombs. There were multiple bombs during the war, and overall they killed way more people than the two bombs did overall. But statistically, the number of people who died during the bombings was far more than the number of people who would die during 5–6 bombings.

Because of Fern’s ability to create close, surprising, and mutual relationships with humans, it can be seen that Fowler intends to show that chimpanzees are capable of a social and compassionate identity comparable to that of humans’. Fern did not meet the expectations of the scientific community when she formed close bonds with the Cookes and the rest of the apes in the habitat. Fern formed such close bonds with her human family, so close that she rejected her own species, delicately calling them “crawling shit” (101). Such a close relationship between two different organisms is indicative of the lack of differences between their inherent natures. The compatibility of Fern in the Cooke household shows that chimpanzees are human enough to be able to form meaningful relationships with humans.

The primate observation that I chose to observe are Orangutan, Squirrel Monkey, and Lemur. This observation took place in the Lowry Park Zoo on October 18th. I went to the Lowry Park Zoo around 2 pm until 5 pm. The purpose of this observation is through primate’s anatomy, locomotion, and behavior to getting know them better, and how they are differences and similarities compare to human beings. When I got there, the Zoo was already very crowd.

Humans have been examining and studying non-human primates for ages in an attempt to further understand the reasoning behind human behavior and base instinct. While it would be ideal to study non-human primates in the wild, away from possible interference from human civilization, that is often not the case, especially for students, and in this case the non-human primates have been observed within captivity. Specifically, the species observed were the Tufted Capuchin monkey (Cebus apella) and the common squirrel monkey (Saimiri sciureus) at the Living Links to Human Evolution Research Centre in Edinburgh Zoo. The tufted capuchin monkey is most commonly found within the neotropical regions of South America including: Columbia, Ecuador, Peru, Brazil, Suriname,

Learned behaviors are important in primates because it shows that they can evolve by learning knew things and passing them onto there offspring. This ability of learned behavior is special in primates because of there intelligence. All animals have instinctual behaviors, which are needed to keep themselves alive, but not all species have learned behaviors as sophisticated as

Studying captive primates can help us learn not only how they behave, but also how they are similar or different to each other and humans as well as give us insight into the effects of captivity. This paper will be describing, comparing, and contrasting the behavior of two species of captive primates at the Alexandria Zoo, golden lion tamarins and howler monkeys, as well as discussing the possible effects captivity could have had on them. This paper will also discuss any human-like behaviors observed in the two primate species and what we as humans could learn about our own behavior by studying primates. The two primates I observed were 1 of 3 golden lion tamarins (Leontopithecus rosalia) all of unknown gender and a solitary female howler

Among anthropologists it has become increasingly clear that the concept of race having a biological basis is fundamentally flawed. There a number of flaws with this concept of race. One issue is that features attributed to race, such as skin color, very across the globe in a clinal fashion rather than in uniform groups. Another issue is that there is more in-group variation within races than there is variation between races. Finally, human variation is non-concordant.

Over the course of the semester I have learns a lot about primates. Some things I already had knowledge of, a lot were things I could not have even thought were primate related. From the (occasional) meat-eating chimpanzee to the shock of lemurs being more primate than weasel my knowledge has expanded a great deal. For this project I chose to observe a primate that I was not too familiar with. I felt as though as soon as someone hears the word “primate” the first thing that comes to mind are either: chimpanzees, gorillas or orangutans.

Title Abstract 150 Introduction500 405 Personality is a range of correlated behaviours that are expressed in different contexts. Animals exhibit behavioural syndromes, which is a set of behaviours seen in multiple scenarios. (huntingford 1976 as read in Pelligrini et al., 2010)..Find this!. An example of a behavioural syndrome is the shy/bold continuum (i.e. proactive-reactive) (Wilson et al., 1994 as read in Pellegrini et al., 2010). Boldness has been studied in many species.

This phenomenon has also been termed as "kernel of truth hypothesis" (Berry & Finch Wero, 1993). Indeed, there is growing body of evidence that suggests that the facial appearance may provide some valid information regarding a person's personality and health. Since faces are processed largely holistically (Tanaka & Farah, 1993), modern research focuses particularly on whole face
