The Chimpanzee (Pan troglodytes) and the Bonobo (Pan paniscus) share many similar traits and characteristics but also vary greatly in certain aspects. Tucked away in the jungles of central Africa, Bonobos and Chimpanzees live geographically isolated from one another. This is likely why the two species have developed distinct social behaviors and physical traits from each other. Having a shared common ancestor, the two primates do have a lot in common. They share much of the same genes and are often indistinguishable to the untrained eye. The distinction between Bonobos and Chimpanzees becomes most apparent when one observes the social behaviors of the two species. Chimpanzees live in a patriarchal society with an aggressive alpha male as …show more content…
According to Bonobo researcher Takayoshi Kano, mothers are “the core of bonobo society, holding the group together” (Raffaele, 2006). Mothers and their children will stay together for their entire lives. Offspring are born into the social class of their mothers. Offspring of respected females enjoy the same privileges as their mother. However, when the mother passes away, her offspring are left to fend for themselves. They start from the bottom of society and must earn their way back up to the top on their …show more content…
It is also known that the two species do not reproduce and raise their young in the same way. In chimpanzee society, infanticide is common. Infanticide is “the killing of offspring unrelated to a male chimpanzee” (Parish, Wrangham). However, because bonobos are so sexually active with almost all members of their tribe, clear lines of paternity become blurred. Without paternity, infanticide is eliminated. This is “a huge evolutionary advantage for female bonobos, because more of their offspring will survive” (Parish, Wrangham). Bonobo young are raised in much more of a group setting than chimpanzees. The strong bond between bonobo females allows for them to share responsibilities for raising offspring with the whole group. In chimpanzee societies, females “disperse into the forest with their infants to find enough food to eat” and do not spend large amounts of time with other females (Parish,

Primates housed in organizations like zoos and laboratories have developed catastrophic behavior; due to the lack of their natural habitat and the lose of freedom to pursue their own lives. Chimpanzees have directed themself to attempt abnormal and often revolting behavior. During their life in captivity they exibit biting themselves, drinking urine, eating feces, pating genitals, rocking, plucking hair, and fumpling niples (Birkett and Newton-Fisher). Another factor that gives chimpanzees
In her article “In the Bonobo World, Female Camaraderie Prevails,” Natalie Angier describes primatologists’ findings about bonobos, both in captivity and in the wild. Bonobos and chimpanzees are humans’ closest relatives. Chimpanzees and bonobos, not surprisingly, are sister species, but their behavioral patterns and societal structures are significantly different. Chimpanzees form patriarchal groupings in which female friendship or alliance is uncommon. They’re aggressive prone to violence among themselves. Bonobos “[defy] the standard primate rulebook.” The bonobos form matriarchal groups in wherein female bonobos “often [band] together to fend off male aggression.” The bonobos also use sexual contact as a means by which to settle disagreements, ease tensions, and show respect. Angier writes about the bonobos through a heavily human lens; she describes pacts, “girl-on-girl frottage”, sorority, and matchmaking. This creative license undercuts the very real scientific research Angier describes, making it difficult upon the first reading to discern fact from anthropomorphized fiction. However, upon rereading it becomes evident that bonobos and chimps actually
4. Due to lack of facial Muscles they cannot make facial changes that other primates use to communicate.

According to National Geographic, scientists have sequenced the genome of the chimpanzee and found that humans are 98.5% similar to the ape species. The chimpanzee is our closest relative in the animal kingdom; however, some people are not aware of our resembling traits with chimpanzees. Jane Goodall’s, In the Shadow of Man, describes some similar traits humans and chimpanzees have, such as their facial expressions and emotions, use of tools, and diet. Chimpanzees portray their emotions through a number of facial expressions and mannerisms. Just like humans, they undergo mood swings, jealous rages, and laughter.
Thesis: Based on the observable behavior and culture of bonobos, compared to chimps, bonobos provided better insight and blueprint of precursor of human behavior than the chimps.
Bonobos are a species that use sexual behavior as the key to social life. In most other species, chimpanzees or humans, sexual behavior is a fairly distinct category. Despite this sexual behavior, the bonobo’s rate of reproduction is the same as that of a chimpanzee. A female gives birth to a single infant at intervals of five years, sharing this characteristic with chimpanzees of partial separation between sex and reproduction. Humans have a different rate of reproduction in that they give birth to 1-2 infants within a three-year period and raise them together. Although humans rate of reproduction is different, and adapted to raise children simultaneously, than both of these primates their sexual behavior is most similar to that of chimpanzees.
Kappeler et al (2003) suggest that life history variables also should be included within the socioecological model due to the inferences and conclusions that can be devised of the behavioural ecology of primates. The framework is under constant remodeling due to the new challenges that arise as the variation being observed does not fit within the model’s predictions (Janson, C., 2000). This is likely due to the role of the environment and its significant impact on studies due to the restriction on study sites and opportunities and the unlikelihood of having been able to study primates with no human influence if possible are under high security. And even the impact of the physical environment has been shown to impact the social organization of primate groups (Fiore, A. D., et al, 1994). There is also further research that suggests the significance of the role of infanticide as a reproductive strategy in many primate species (Van Schaik, C. P. et al., 2000). This action is used by the males of the species to eliminate the offspring that pose risk to the male’s reproductive success by extending the time of female
While chimpanzees frequently hunt in packs for other groups of monkey species, it is believed that bonobos tend to hunt individually and focus their efforts on more medium sized terrestrial prey.
Due to their close evolutionary relationship to humans, chimpanzees and bonobos have been widely studied and used as models for the behavior of early hominids. In recent years, new information regarding the social behaviors and ecology of bonobos has come to light, and this has warranted many interspecific comparisons between bonobos and chimpanzees: “Chimpanzees have been characterized in terms of their intercommunity warfare, meat eating, infanticide, cannibalism, male status-striving, and dominance over females. Bonobos, meanwhile, have been portrayed as the ‘Make love, not war’ ape, characterized by female power-sharing, a lack of aggression between either individuals or groups, richly elaborated sexual behavior that occurs without the constraint of a narrow window of fertility, and the use of sex for communicative purposes” (Stanford 399). Over the course of this paper, I will provide evidence for the dichotomy between these two species, with particular attention to the histories of their research, the nature of their social interactions, as well as their sexual behaviors.
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.
I observed chimpanzees in the Kimberly-Clark Chimpanzee Forest exhibit at the Dallas zoo. These African apes, like humans, are hominoids and fall into the larger category of catarrhines. Their scientific classification is Pan troglodytes. There were about ten chimpanzees in that habitat. Most of them were grown adults, except two children. They were robust and had black fur. The average weight of the chimps was listed on a display to be about 115 pounds.
There are at least 145 living species of the suborder Anthropoidea . Over 90% of them are monkeys. The remaining species are apes and humans. The anthropoids (members of the suborder Anthropoidea) have been the most successful primates in populating the earth. They are generally larger, more intelligent, and have more highly developed eyes than the prosimians.
While taking the biological anthropology course at the University of Arkansas, I have learned the extent of primate patterns and behaviors, most importantly, in relation to human behavior and social interaction. There is one primate that single-handedly relates to humans in terms of human characteristics such as sexual behavior, how they handle aggression, their psychological demeanor, movement, and socialization. The pygmy chimpanzee, also known as the bonobo, is this particular primate. The bonobo is known for their ability to resolve problems with in their life through sexual intercourse. I chose this topic because I find this fascinating, seeing as how I have already written a research paper on human development and sexual interaction between different human cultures. This paper investigates bonobos as incredible creatures in comparison to human beings in every aspect socially with conflict resolution and psychologically with how they mentally observe their surroundings with a lot of consideration of their environment. The bonobo, Pan paniscus, typically associate better with the opposite sex. I have found in my research, while reading “Cooperation in Primates and Humans”, that the males often form closer bonds with females (Kappeler 34). This could be because of the sexual aspect of it, or because females are dominate in this species. The maternal groups are primarily ran by the females when given the opportunity for food or order to the rest of the group. In human history, patriarchal societies were formed by nature and have evolved giving females more rights and opportunities now that modernization has taken place. That being said, humans and bonobos do differ this way.
