Chimpanzees are the closest primates to humans. Like us, very smart, very clever primates have incredibly complex and sophisticated social structures. Many studies have shown that they are altruistic, plan for the future, and have basic arithmetic skills.
Chimpanzees are all black, but they are born with pale faces and white tails, which get dark as they grow older. They have prominent ears and both males and females have white beards.
Locomotion patterns include quadrupedal knuckle walking and occasional bipedalism. Chimpanzees are both terrestrial and arboreal, with the amount of time spent on the ground varying between study sites and between sexes all chimpanzees build sleeping nests in trees at night.
Visual and phonetic communication

is important for chimpanzee society. A collection of facial expressions, posture, and sound functions as signals during interaction between individuals and groups. Chimpanzees have particularly expressive, hairless faces and facial expressions play an important role in close-up communication between individuals. Mating takes place all year round and there is no evidence that there is a certain seasonal birth period for female chimpanzees.
The number of estrous chimpanzees is related to food abundance due to the energetic requirements of ovulation and mating, female chimpanzees are more likely to come into estrus during times when food is readily available. Most of the chimpanzee's reproductive behavior is promiscuous, indicating that females mate with multiple males in rut at the same time, most of which occur during the maximum rotation period of 10 days. There are other types of reproductive strategies that are recognized as well. Restrictive mating, where the dominant male restricts other males from mating with estrous females in the community, consortship mating, where an adult pair leave the community for several days to weeks, and extra-group mating, where females leave their communities and mate furtively with males from nearby communities. Chimpanzee communities and mating groups do not always overlap when considering the diversity of reproductive environments. This may have evolved because women have limited options for their spouses after they have devoted themselves to society. By having various strategies, female chimpanzees can expand the range of male they choose as they do not lose important men's support in their communities. Having various strategies also maximizes the chances of male reproductive success. Men can change their mating strategy depending on their
position in the ruling class. Infanticide has been documented at Gombe, Mahale, and Kibale study sites and is often attributed to sexual selection theory, males kill infants that are suspicious to be not their own. , infanticide shortens interbirth intervals by inducing cycling in females that lose infants, and infanticidal males thus increase their chances of siring offspring. Infanticidal behavior by females has also been observed, though there is some question as to whether these were isolated incidences of pathological behavior, or if it could be related to dominance rank in females.
To start, research shows that there are a striking number of similarities between humans and chimpanzees in context to their social behavior.
This article, titled Common Ground, written by Barbara Smuts, points out the main differences between humans and apes, such as our upright stance, large brains, and capacity for spoken language and abstract reasoning. However, the main point of this article is to emphasize the many similarities that apes share with us. Smuts goes into great detail about how human social and emotional tendencies are very reflective in the family of apes.
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.
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.
Chimpanzees make tools and use them to procure foods and for social exhibitions; they have refined hunting tactics requiring collaboration, influence and rank; they are status cognizant, calculating and capable of trickery; they can learn to use symbols and understand facets of human language including some interpersonal composition, concepts of number and numerical sequence and they are proficient in spontaneous preparation for a future state or event.
They have wide chests and their arms are longer than their legs. Chimpanzees’ hands have four long fingers plus an opposable thumb. Their feet have five toes which includes an opposable big toe. Chimpanzees’ can grasp things with both their hands and their feet. Male chimpanzees are larger than female chimpanzees and are slightly sexually dimorphic. Chimpanzees are quadrupeds that typically walk using the soles of feet and the knuckles of their hands. They sometimes walk upright only when they need to use their arms to carry things but this is a rare occurrence. Chimps are also good at brachiating and climbing trees which is where they spend most of their time even when they sleep. Their dental formula is 2.1.2.3. Chimpanzees’ have y5/x4 molars, making them frugivores, and a diastema to fit their upper canines. Their diet includes fruit, leaves, flowers, seeds, smaller mammals, birds, insects, and grubs. When chimps aren’t resting, they can be very active. I enjoyed watching the Chimpanzees’ swing on the ropes and climb up and down the trees. Chimpanzees are
The mother-infant bond is the familiarity and attachment a mother forms with her offspring. These helpless babies are reliant on their mother’s nurture for survival. This dependence reaches farther than a physiological need. Infants rely on their mothers for a wide variety of demands. The mother-infant bond is critical to maximizing the fitness of each individual, as well as the growth of the species.
Non-human primates are the only animal that imparts a large number of essential cognitive aptitudes with humans.
All primates have the same sensation and are capable of receiving excessive amounts of information. All senses, sight, smell, taste, hearing, and touch are essential to the development, survival, and overall well-being of living primates. It is fascinating how non-human primates, without language, can communicate in the same ways as human primates, with language. Non-human primates and human primates are highly developed mammals that possess many of the same communicative characteristics, but still differ greatly. Non-human primates fit into the category of not having language, but being able to communicate.
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.
Chimpanzees portray their emotions through a number of facial expressions and mannerisms. Just like humans, they undergo mood swings, jealous rages, and laughter. For instance, Goodall observed during her research that a male gorilla “would threaten [me] with an upward and backward movement jerk of his head…” Some of their emotions are easy to read, while at other times we have to look at multiple places on their faces to understand their feelings. A chimpanzee also uses its facial expressions and sounds to communicate with each other, such as hoots and yells.
...rain, wrist, shoulder, etc. Chimpanzees are highly intelligent where they know how to use tools for food and other purposes. They are also capable of having reasoned thoughts where they can use their memory and process information. Not only can they learn the American Sign Language, they also have a concept of self where they can recognize themselves in mirrors (something most animals can't do). Many people get caught up in the difference between animals and humans, but these animals should be given certain rights. For example, they deserve the right to freedom from suffering and abuse. Humans are primates just as chimpanzees are; just because they can't communicate in the same way we do, that doesn't mean they should be held prisoner against their will, or get tested on without having a say in that. I believe all animals have a right to a blissful, fulfilling life.
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.
In “A Report from an Academy,” a fiction text, Franz Kafka states that we, human beings, are closer to chimps than we think we are. It
Creationists believe that humans were always humans. Humans are classified in the mammalian family Primates. In this arrangement, humans, along with our extinct close ancestors, and our nearest living relatives, the African apes, are sometimes placed together in the family Hominidae because of genetic similarities. Two-leg walking seems to be one of the earliest of the major hominine characteristics to have evolved. In the course of human evolution the size of the brain has been more than tripled.
