One of the recurrently intense debates in contemporary society has to do with the origin of male and female behavioral differences in human children1. It is hard to understand to what degree are gendered behavioral differences innate and biological, and to what extent is the surrounding environment influencing such behaviors. Can we learn anything from our closest living relatives who grow up without being encouraged by the society to behave in a certain way? Chimpanzee (Pan troglodytes) adults differ in sociability, reflecting the ability to function in a complex social setting that ultimately determines their reproductive success2. How soon do these sociality differences begin to arise? To determine whether these sociality differences are innate or learnt we need to dig into infant social behavior, the age window when they are still independent of social …show more content…
Their fission-fusion social organization includes small, temporary subgroups that travel and forage independently within their community’s home range5 (Fig.1). In East African chimpanzees, adult females are less gregarious than adult males and represent the dispersing sex2. As mothers, they often spend much of their time accompanied only by their dependent offspring6. Meanwhile, adult males are highly social and philopatric; they live in larger groups and form enduring social bonds with individuals of the same sex7. Chimpanzees have a male-dominated society in which rank is a constant battle; therefore males can strongly profit from coalitions. Cooperating in home range defense activities, hunting, and obtaining access to sexually receptive females have an advantage in terms of maximizing their fitness, including increasing their reproductive success and maintaining their social status2. By contrast, females were found to avoid other females to decrease competition for food and
A Primate’s Memoir, written by Robert Sapolsky, documents the author’s time in Kenya while he studied the various behaviors of a troop of baboons. One of the key aspects of the book was the social rank that developed within the troop. Female baboons have a social hierarchy that is fairly cut and dry. The eldest baboons in the troop are considered the higher-ranking females, and as the baboons get younger, so to follows the string of dominance. The ranking for males was essentially from the strongest baboons to the weakest baboons. The baboon at the top of the social hierarchy was considered the alpha male. This social rank has huge implications for the troop in regards to which baboons mated with each other. If another baboon wanted to become the alpha male, then he would have to challenge the current alpha male to a fight, and win. The baboon’s distinct personality mixed with their instincts are the primary factors for where one lands on the social hierarchy. Another key aspect of the book was the strategies that took place when the baboons wanted to mate with another baboon. Similar to humans, the baboon males tried to impress the female baboons in a way that would make them want to mate. The rank of the male is considered to be one of the greatest factors contributing to what mate they end up with, because there is nothing more impressive than becoming a high-ranking baboon. Also, there were instances of lower-ranking baboons strategizing and forming teams with other baboons to become a higher ranking baboon for the mating possibilities. The baboons in the group are considered a patch-work of different troops, as it is common for one baboon to move to different groups frequently.
There are contrasts in tool kits used by different groups of chimpanzees, which seem to be a result of the environment in which they live as well as information that is shared by the group. For example, in 1973 it was reported that chimpanzees in Gombe did not use hammer stones, but those of Cape Palmas did. We will explore the tool use of Chimpanzees from the wild, including Gombe, Tai National Forest, and the Congo Basin---and contrast those with Chimpanzees in captivity in locations of Zoo’s both in the United States and abroad.
As our neighboring living families, chimpanzees as well as bonobos have been extensively used as prototypes of the behavior of early hominids. However, In modern years, as statistics on the social behaviors or conduct and ecosystem of bonobos has evidently come to light, a lot of interspecific assessments have been done. Chimpanzees have been described in terms of their intercommunity struggle, meat eating, infanticide, anthropogy, male position-striving, and supremacy over females. Bonobos, for the meantime, have been depicted as the ‘‘creator of love, but not a war’’ ape, categorized by female power-sharing, a deficiency of hostility between either characters or groups, expounded sexual behavior that happens without the restraint of a thin window of fruitfulness, and the usage of sex for communicative determinations. This paper evaluates the indication for this contrast and reflects the reasons that distinct portrayals of the two great apes have advanced.
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.

Social groups of primates closely relate to sexual dimorphism, because how each of their communities interact with one another plays a large role in sexual selection. Sexual selection, as Darwin stated, is a key factor and cause in the morphological dimorphism between sexes of a species. Additionally, sexual selection comes from male competition, which directly correlates to primate’s social structures. For example, genus gorilla is a part of a polygynous mating system, which consists of one male and multiple female. This creates an environment where males must compete with one another to reproduce and create offspring. Due to this competition, males must prove to be strong and attract themselves to females to ensure reproductive success. These strong male traits are favored in sexual selection, because the females are highly particular about the male they mate with, so there become specific male traits that are most desirable. Therefore, in polygynous groups, sexual dimorphism is the greatest (Frayer, Wolpoff, 1985). In comparison, a monogamous primate such as genus hylobate or gibbons has a social structure that consists of a more nuclear based family. There is a lot less male competition because males do not mate with multiple females. Therefore, primates are less dimorphic in monogamous social structures (Frayer, Wolpoff,
Historically throughout the earliest centuries, the term gender and sex has been a vital focus in distinguishing the overlap between gender differences. Matlin’s book, Psychology of women, explains that gender similarities of females are at most similar to men, however, considering that culture influences individual’s beliefs; women are expected to behave the way culture entitles us to (Matlin, 2008, p.8). In contrast, the book also reveals that women and men are different from one another in terms of social and intellectual skills according to biological inheritance (Matlin, 2008, p.9). These two perspectives expose valid reasons in terms of the roles that men and women play in society. Even though feminists and female psychologists imply that both men and women are exactly the same, there is however, a strong statistical correlation related to the comparison of men and women according to different brain wiring, strength and endurance (York, n.d., para.10).
Introduction The topic of gender differences must understandably be approached with caution in our modern world. Emotionally charged and fraught with ideas about political correctness, gender can be a difficult subject to address, particularly when discussed in correlation to behavior and social behavior. Throughout history, many people have strove to understand what makes men and women different. Until the modern era, this topic was generally left up to religious leaders and philosophers to discuss. However, with the acquisition of more specialized medical knowledge of human physiology and the advent of anthropology, we now know a great deal more about gender differences than at any other point in history.
As stated in the article, “each ape’s social success depends on what other group members are up to, natural selection has favored the capacity for social maneuvers and [superior intelligence]” (2). Natural selection also favors apes because they are not ones to dwell or hold grudges on other apes when they get into feuds. Frans de Waal, a primatologist at the Arnheim Zoo in the Netherlands, shows how natural selection has also promoted the ability to strengthen the relationships of others. In his example, he gives an account of Mama, the most influential female in the colony, who would reconcile other apes after they got into
In the film, Jane set out a pile of bananas so she would be able to observe the chimp’s behaviours. She realized that the stronger, more dominant males were the ones that took most of the bananas, while the smaller, weaker ones, (primarily the females and babies) stayed back. In our society, we may not fight over a pile of bananas, however, we may fight over a pile of money. We would probably not be polite and take only 30 dollars and save some for everyone else. We would be greedy and try to take all the money. This same type of situation applies to the chimpanzees.
...o carry out a perfect experiment and consequently all evidence will be flawed. It is necessary to focus upon evaluating the severity of such flaws. One could argue that the biosocial theory is more convincing as the many strengths of the socio-biological and social learning theories are combined providing a credible explanation. This also means the scientific facts in the socio-biological theory are no longer undermined but indeed strengthened by evidence to support learnt gender-appropriate behaviours. The biosocial theory allows for both schools of thought to be equally considered. Overall the Hegelian dialectic mechanism can be applied; the hypothesis, in this case the socio-biological explanation, and the antithesis, the social learning paradigm, must co-exist to produce the resulting synthesis, gender-appropriate behaviours. Thus girls are both born and made.
The chimpanzee remains a unique species native to Africa with distinct characteristics and lifestyles which remains threatened by human influence. Chimpanzees, oftentimes classified as monkeys, belong to the great ape family. Despite this classification, chimpanzees remain the closest living relatives to humans, sharing about 98% of their genetic makeup with them, according to Chimp Facts. The chimpanzee features long arms which extend past the knees, opposable thumbs, and a distinct mouth. The body of the chimp remains covered with brown or black hair except on the face, ears, palms, and soles of feet. The chimps typically rely on all four of their limbs for travel, but also possess the ability to walk on two legs for up to a kilometer. Chimpanzees primarily travel along the ground but spend their days in vegetation nests up in the trees. According to “Chimpanzees,” the species possesses extremely social qualities resulting in communities of both females and males. The term “Fusion-fission” describes the flexible community structure. “All community members know each other, but feed, travel,

The same concept was expressed by Edward O. Wilson (1992), father of sociobiology at Harvard University. According to him, females tend to be better equipped in characteristics like verbal and social skills, security needs and empathy than their counterpart. In the other, Males tend to be better in spatial ...
I am almost always surrounded by the interactions between children and their parents. I hear it at my work, I hear it in restaurants, but most of all I hear it at my house. My mother owns a daycare and every night I hear parents being hit by a barrage of questions. When children are being picked up they always have a couple of questions for their parents. Children are always asking about the meal for the night or whether they can go over to a friend?s house or have some body over. Every night I see 12 different children with twelve different parents and it seems that each parent acts differently then the next.
