It is said that the humanoid existence begins in Africa. It is no coincidence that Africa is also the home to Chimpanzees, Pan troglodytes, and Bonobos, Pan paniscus. These are humans’ two closest living relatives, both sharing almost 99% of the human genome through common descent. While humans were said to have separated from Chimpanzees around 5-7 million years ago , Bonobos separated from its Chimp cousins around 2 million years ago . Bonobos inhabit a single part of Africa, Democratic Republic of Congo South of the Congo River, unlike the Chimpanzee, which inhabits Across West- and Central Africa, with remaining populations distributed over several countries. While these two apes where once thought to be the same species, up until the beginning of the 20th century , there are many differences socially, as well as physically, that make Bonobos more than a Pygmy Chimp. With disparities in morphology, behavior, perhaps even emotions and cognition, and known as the “make love, not war chimp” , how can this ape be so vastly different from its notoriously violent Pan cousin, but yet share the same amount of similar DNA to Homo sapiens? And what does this mean for the studies of human and past humanoid behavior? Physiology With a 99.6% genetic similarity to Chimpanzees , the physical appearance of Bonobos is very similar to them. The length of the legs, in proportion to the arms, Bonobo’s dark faces, pink lips, and more slender stature are just some of the cosmetic differences between them and Chimpanzees. Bonobos are notorious for their bipedalism, walking upright. Granted Chimpanzees can preform bipedalism when needed, but do not match the ease and grace of the Bonobo.

Dr. Goodall is a well-known British primatologist who has discovered a substantial amount about primates in her many years of research. She has written numerous books, including one that we will be going into depth about called, “Through a Window.” Her book contains personal experiences, research findings, and even pictures to help the readers visualize her scientific breaking moments from her thirty years with the chimpanzees of Gombe. She states that there is are minor differences, and several similarities between humans and the chimpanzees. We will discuss these differences and similarities through their social behavior, intellectual ability, and emotions. To conclude, examine Goodall’s research to adopt what her findings can tell us about our early ancestors, and whether or not her study coincided to the steps of scientific methodology.
Inside the chimp habitat, I noticed a sign which read: Look here for a “zoo” born! When I saw it, I recalled that earlier during the day, a senior docent named Rhonda who worked with the gorillas had told me that there was recently a newborn chimp. She said to look very closely to find the baby because the mother was extremely protective of it. She had also mentioned that the newborn’s furless skin would be very pink. At first, I looked very keenly for the small new chimp who had just been born this year, but I couldn’t find it. I finally spotted the baby after I moved to a different position to view the chimps from the open air viewing area. The infant was just as Rhonda had described it: nestled in its mother’s arms as she shielde...
Chimpanzees are a lot like humans in their behaviours. They are extremely smart since they are able to make and use tools and weapons. The female mothers are very affectionate and protective over the young and the rest of their family. The young chimps are also very dependant on their mother for necessities such as food, shelter and warmth.
The idea that humans could possibly have evolved from apes was thought impossible until about 150 years. Charles Darwin, an English naturalist and geologist, best known for his contribution to evolutionary theory, stated “humans evolved from an apelike ancestor” (1). Still after Darwin’s theories, many people still doubted the chances of this being true. Just in the past decade have scientists reached a general agreement about the evolutionary relationships between humans and apes. DNA evidence indicates that chimps and bonobos are more closely related to humans than they are to gorillas! Technically humans are a kind of great ape, and that is why throughout the article Smuts will refer to apes as forest apes.
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.
Starting with chimpanzees, which have been observed on multiple occasions to kill infants, though most of these killings are directed at other groups of chimps [1]. This has been observed on multiple occasions, and would often include cannibalizing the infant [1]. It has also been observed that females who have had their child killed will occasionally join the group that killed it, and allow to be copulated with [1]. Though admittedly from the article, they were not absolutely confident in whether every female that had an infant killed was from an outside group [1]. This infanticide seems to be more of a result of warfare and conflict, rather than of outright greater fitness to individual chimps, however it does occasionally lead to a new female in the group [1]. This both lowers the reproductive success of their rivals, which allows them to exploit their rivals lesser numbers and increase territory. One thing that sets chimps apart from the other primates that are going to be mentioned is tha...
...eportedly the chimpanzee became an endangered species in 2002. Vital funds for zoo affiliated research and field work should be found elsewhere, because fooling around with another's life – human or animal – is not ours to manipulate.

Harlow observed the monkeys all during their life including the growing up stage from adolescent to adult see what kind of vibes they’ll give of in social environment as adults. Harlow noticed that monkeys had very odd behavior. They didn’t demonstrate any normal breeding activities, and many of the females did breed became very poor mothers and did not try to take care or even protect their offspring.
Chimpanzees (Figure 1) are the closest living relatives to us, and they share 99 percent of our DNA (1). Chimpanzees have distinct group territoriality. Male chimpanzees “patrol” near the boundary between the two ranges, at that time they move very carefully and quietly, and they can cease to listen and observe the range of their neighbors. Patrolling individuals are likely to face cruel and violent attacks, injuries, and even deaths. Intense excitement and aggressive display can occur if the two parties of two communities encounter each other. Usually, the larger group holds its ground, and interaction between different chimpanzees communities may also lead to gang attack. Expanding the community range is necessary to their social organizations, the males cooperation can defend the territory and increase the reproductive rates of the resident females by excluding female and male competitors. Body contact is common in their social life such as grooming (1). Usually, chimpanzees groom each other as a way to show harmony and solidarity in their society (Figure 2). Grooming each other demonstrates the deep bonds and close relationship between them. In addition, they can even hug, hold hands, touch, kiss each other as a way of emotional expression (2).
According to National Geographic, scientists have sequenced the genome factor 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.
Humans know or understand the theory of evolution and how they evolved from apes, but there is always talk of a missing link between apes and modern humans. Apes did not just suddenly evolve into modern day humans. Apes evolved into another species that fall into the relation of modern humans. This is what the missing link is referring to; we call the species hominins. Hominins comprised of many species actually, including but not limited to, Australopithecus afarensis and Homo erectus. Homo erectus may have been a direct descendant of modern Homo sapiens. These species hold strong evidence that they are the missing link between apes and modern humans. There are many pieces of evidence that lay the path of evolution from these species to modern humans, “…these include anatomy, living primate behavior, and genetic relationships” (Stanford, 237). Australopithecus afarensis comes first, existing about 3.9 to 2.9 million years ago, with intermediate anatomical traits between living apes and modern humans; their fossils were found in Africa (Yukimoto). About a million to two million years later, the species Homo erectus came into existence and lots of evidence has been found about this particular species, in fact, it was probable that it was the first species to leave Africa (Yukimoto). These species are significant in the evolution of modern humans. We do not have a clear path or even understand why these species emerged when they did or how they, in theory, eventually evolved into modern humans. We can only assume these things, by using various evolutionary processes such as natural selection, genetic bottleneck, and many more.
In his lecture, primatologist Robert Sapolsky explains the uniqueness of humans as well as our similarities to other primates. In doing so, he broke it down into six points of interest: aggression, theory of mind, the golden rule, empathy, pleasure in anticipation and gratification postponement, and lastly, culture. Professor Sapolsky approaches each point with interesting fact-based examples thus allowing me to gain insight on humans and other primates. Sapolsky’s knowledge of primates along with his scientific background allows him to make a clear argument that one cannot simply ignore.
Bonobos and gorillas are often found socializing in groups but orangutans are more solitary primates usually keeping to just the children they have (Absolutely Apes). Most scientists believe that bonobos are the most intelligent of the primates(Absolutely Apes). They share many of the behaviors us humans do day to day, like teaching...
