Primates are a big topic in anthropology that is crucial for us to learn and study about. Anthropologists study primates from an evolutionary viewpoint as well as an ecological viewpoint, focusing mainly on their behaviors, their natural environment, and their psychological traits. Behavior is known to be evolved from the operation of natural selection. Behavioral genetics is how genes can affect our behavior, which can viewed as a product of complex interactions between genetic and environmental factors. Social structure influences individual behavior, which can blur the distinctions between social and individual behavior. There are many factors that influence social structure, including body size, basal metabolic rate, diet, distribution …show more content…
There are dominance hierarchies, which are a certain degree order by establishing parameters of individual behavior and aggression is used frequently to increase an animals status within a group. Dominant animals do not give into confrontations, but are given priority by others. Increased reproductive success of high ranking animals is one primary benefit of dominance, according to some primatologists. Males are typically dominant to females in organized species groups. Dominance is indicated by gestures and behavior and all primates learn their hierarchy position. Communication is used throughout every primate and animal and it includes any behaviors, scents, and autonomic responses. Communication is used to indicate submission, reassurance, or amicable intentions. Vocalizations are used as a form of communication to inform others of predator or food presence. Social living would not be possible without communication. Aggression is very common with primates, especially for competition of resources, such as mating partners or food. Competition between makes usually results in injury or death while competition between females results in chasing the subordinates away or taking their food. Certain amount of aggression does help keep groups in order and to protect each other from group or individual resources. Physical contact is one of the most important factors in primate development. Not all primates are

In primates such as chimpanzees it is imperative to look at their culture to understand their intelligence. Culture in this circumstance means a specific set of behaviors obtained through learning in a population/species. Chimpanzee’s intelligence is quite unique how they interact with their environment and use it to their benefit just like humans. They have the ability to overcome the obstacles of everyday life through learning and the ability to use tools to create a better quality of life. The complexity of their intellect is different from any other animal ever seen. A significant part of chimpanzee intelligence that sets them apart from other primates and puts them closer to humans is the way they exhibit social learning within their culture and interactions within their environment.
Thesis Statement: Despite the rampant protests of animal welfare organizations on encaging primates in zoos since primates typically show abnormal behavior, zoos in the National Capital Region claim that human interaction and enrichment programs help alleviate the stress and trauma primates experience.

There has been an age long debate to whether or not primates have culture. This is based on the idea that primates may have certain behaviors that our taught rather than already being programmed in their minds biologically. Some would argue that a certain action that a primate does wouldn’t necessarily be something that primate was born knowing; but others would argue that it was something that was something they knew in their subconscious mind. Notable arguments that would be in favor of culture in primates would include their use of tools, how a primate eats, and how they interact; arguments against the theory of culture in primates would proclaim that a primate’s habits are determined biologically and not affected by outside sources.
Our earliest ancestors are primates. They are our closest relatives which is why we can see our behavior’s and practices in them. If we observe them we can get a better understanding of them and us, human beings. But unfortunately we all don’t get the chance to see a Primate right in our backdoor. So the best thing I could do for my observation was to visit them at the zoo.
One of the biggest ideals shown throughout history is the need for power and dominance. Whether it comes from Hitler taking over Germany and trying to enact a full-scale genocide of an entire race or a Savanna baboon alpha male being challenged by a headstrong youth for dictatorship of the tribe; the need to be the one who calls the shots will always remain an instinctual thought hardwired in our brain. To some this comparison may seem off based and farfetched in regards to similarity, however looking at Sapolsky’s research, the dominance in the animal kingdom can get rather similar. In a quote from his book A Primate’s Memoirs, Robert states, “Solomon entered the fight, ably taking on both while they were preoccupied and exhausted. Result: number 203 dead, Aaron badly injured, Solomon settling in to his reign” (Pg 22-23). The clichéd quote of “all is fair in love and war” could not sum up this act of social dominance any better. Solomon, who was number 3 in the chain of command, waited on the arduous fight of the two contenders to wage on...
It has been believed that culture is unique to humans and no other groups of animals have culture, but recent evidence refutes this ideology. Before getting into the meat of the argument, it is important to first address the issues regarding the ambiguity of the term, “culture.” What is culture? Many scientists may argue that culture is the way of life for a group of individuals, this definition includes the values, beliefs and traditions of the group (Sapolsky, 2006). Other scientists may argue that culture is the transmission of habits and information by social means (Sapolsky, 2006). Despite the different specifics of what culture is, almost all scientists would agree that culture is transmitted socially through social learning that promotes the transfer of information between members in a group (Boesch and Tomasello, 1998). Based on these notions of culture, it can be justifiably stated that primates have culture. Primates exhibit food preparation techniques, use of tools, communication skills, and most importantly, behaviors of social learning. An exemplar of primates’ capabilities for culture is Koko, the lowland gorilla. Koko, in captivity, was able to learn American sign language, demonstrate self-awareness and the ability to deceive.
Men want to protect their area of living so they reduce their competition by limiting the men they are surrounded by. Every time there was more guys in a scene than women, there was arguing about who should get what and why. For example, a guy set up a farmers market in the show right next to another man’s grocery store. The close proximity created competition between men and their areas. Just like when Dean was more protective of Rory when Jess moved into town. This behavior is similar midst the Gorillas. They tend to live with one adult male (even though they have been known to have more than one male in a group) and multiple females with their offspring (Cawthon). Male Gorillas are expected to leave their natal group, the group where an animal was born and raised, in order to keep the breeding selection diverse, but this also creates for a non-cohesive male group (Lewis, Jurmain, Kilgore 138). However, not ever monkey group operates like
Despite the fact laboratory studies are vital in order to acquire useful information about culture in primates, it also places the primates in a stricter, unnatural, or unusual location for animals, therefore not allowing them to show their full potential as they do in the wild (Uehara, 2004, p. 108). Cultural behavior in tools (kin based culture) The primate’s intelligence is extraordinary considering how they connect with their environment to survive in everyday life. The ability to learn to use tools to improve the primate’s life is an example of culture and how they survive.

Evolutionary theory is developed from Darwin’s argument that “suggests that a process of natural selection leads to the survival of the fittest and the development of traits that enable a species to adept to its environment. “ Many have taken this a step further by saying that our genetic inheritance determines not only our physical traits but also certain personality traits and social behaviors. There is such a controversy over significant behaviors that unfold because many believe that we are already pre-programmed human species. It has also been argued that evolution is reflected in functioning and structure of the nervous system and that is has evolutionary factors that have a significant influence on everyday behavior. With what is being said means that if we follow the evolutionary theory, then it would be said that we are already pre-programmed from before birth to follow certain protocols in life. Whether it is from finding a mate or by getting a job. It also believed that this theory gives use cues from our own system to follow, providing us with certain aspects of life from our ancestors. By believing in this theory we can determine that the importance of heredity when influencing human behavior. Behavioral geneticists and evolutionary psychologists have both agreed that not only do genetic factors provide specific behaviors or traits but it also shows the limitations on the emergence of such traits or behaviors. What this means is that our genetics will determine how tall we will be to how ...
Monkey see, monkey do. Apes have always been thought to have an increased level of intelligence. Over the years, researchers have attempted to understand the degree of intelligence these primates possess. However, it is essential to understand the definition of intelligence in order to determine the amount of intelligence primates have. Intelligence is the capability of obtaining knowledge and being able to utilize it in everyday situations. There are many hypotheses that focus on the evolution of intelligence in primates that view a number of factors including brain size and modernism. Primate intelligence has been a topic of interest to many because it will allow us to further understand the close relationship between humans and primates. Additionally, we will be able to understand the difference between human and primate cognition. Some studies suggest that the human and primate brains possess many similarities. This demonstrates why primates tend to respond to stimuli in a manner that is closely related to humans. Researchers have conducted a number of studies in an effort to understand primate cognition.
Behavioral genetics is a field of research that investigates the relative effects of heredity and environment on behavior and ability (Plomin, 1997). Two of the primary methods used by behavioral geneticists are the twin study method, first used by Galton (1975) in his studies of heredity, and the adoption method.
Aggression is a critical part of animal existence, which is an inherent driving force to humans, as we, too, are animals. The source of aggression within humans is a long summative list, but before trying to understand its source one must apply a working definition of aggression. Aggressive behavior is defined by Encyclopedia Britannica as any action of an animal that serves to injure an opponent or prey animal or to cause an opponent to retreat. (7) David G. Myers states that aggression is any physical or verbal behavior intended to hurt or destroy.(9) There are many types of aggressive behaviors, which can be differentiated from the factual act to the hidden motives. For example, an aggressive behavior can be negative or positive, accidental or intended, and physical or mental. Aggression can take numerous forms, the act of hitting a wall to release aggression has some of the same roots as playing football and enjoying hitting the quarterback. A child yelling at his parents could be equated, in its aggressiveness, with hitting one’s horn when one is cut off on 495.
