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. Tool-use is regularly reported in chimpanzees. They use many different tools to carry out many different tasks. They use sticks to fish for insects, stones and wood to crack open nuts, leaves to soak up liquid, and branches used as weapons to dominate opponents and frighten off predators. In making tools, they may use a variety of different materials to make the same kind of tool. For example, they use sticks, twigs, bark, and vines to fish for termites. They also may use the same material for different purposes. A leaf could be used as a termite probe, a napkin, or a sponge. 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. Development of Tool Use: While most tools reportedly used by chimpanzees have involved extraction of food, such as with termites and nuts, or throwing rocks in order to knock their... ... middle of paper ... ... wild counterparts.

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.
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
Did Jane Goodall’s research find the evidence about chimp’s tool making? Is the human the only species able to make the tool? How do you correlate this with human culture?
She took this time to recover from a failed marriage and the death of her late husband. She went back to Africa and was greatly saddened by all the harmful pesticides that people were using all around the world. She used her own healing time to study and actually understand inside of a chimp’s head. Her notes suggest that chimps and humans are very much alike. A human’s brain is more complex and can have a greater mind and thinking way beyond the average primate. She concluded while a human can ask further questions about the past, present, and future; chimps let their instincts come over. This explains why chimpanzees are very territorial and aggressive. Her findings also lead to that humans are forever revolving and chimps are not. Aside from her observations, she also unveiled the importance of the idea of conservation and animals’ rights. Goodall keeps pushing for humans to care for their world, wildlife, and themselves. (Editors)

Jane Goodall’s books, Through a Window, In the Shadow of Man, and The Chimpanzees of Gombe, recount her many years as an observer of chimpanzees and other species of monkeys. In Through a Window, she gives her account of thirty years with chimpanzees in the village of Gombe, off of Lake Tanganyika. During those thirty years with her son and husband, she observed and researched the chimpanzees with the help of other researchers. This book is a collection of the observations and data, in addition to the emotions she felt during this era. The theme of Through a Window is that chimpanzees have very human characteristics and feelings, and she proves this through her descriptions of love, war, power, and life in general.
Throughout situations and research conducted by not only Robert Sapolsky or Jane Goodman, but from many other credited sources, we can blatantly see the, if not identical, similarities between the two species of humans and baboons. The most apparent likewise characteristics of this can be read and documented in Professor Sapolsky’s book, A Primate’s Memoirs. Sapolsky, who spent hundreds if not thousands, of hours studying these Savanna Baboons, sheds a vast insight into ideas of social dominance, mating strategies, instinctual prowess, community settings, hygiene, and reform of an entire generation; many of which can be unknowingly seen directly in the common occurrence of a humans daily life.
In Franz De Waal’s book Chimpanzee Politics: Power and Sex Among Apes, social interactions between the chimpanzees at the Arnhem Zoo in Holland are examined. De Waal spends time observing the lives of these animals and comparing them and their ‘culture’ to human culture. The book follows a power struggle between the three dominant male chimps, Yeroen, Luit, and Nikkie. The book does not exclude female chimps and talks about how they influence the role the alpha males play.
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.
... various meat eating habits. The consumption of meat is well documented in the case of chimpanzees and has been considered a systematic facet of chimpanzee behavior: “Chimpanzees incorporate the meat of hunted mammals in their diet…Chimpanzees probably hunt for both nutritional and political reasons in that alliances are cemented by the giving of meat. They also appear to obtain meat for sociosexual benefits in that males sometimes offer meat to females and receive matings in the process” (Stanford 404-405). As compared to chimpanzees, the consumption of meat within bonobo populations is considered rare. If male chimpanzees hunt for meat to fulfill political and sociosexual needs rather than nutritional ones, then male bonobos might be less interested in hunting for meat for several reasons. Firstly, the manipulative use of meat observed in male chimpanzees
Apes have over and over again surpassed other primates in comprehension tests carried out in the laboratory. They are capable of reacting to stimuli in an appropriate manner. Researchers have measured intelligence in primates in a number of situations in an effort to determine the level of cognition these primates possess. Russon and Begun, researchers who have explored ape intelligence state, “In the physical domain, great apes do use tools in ways that require their grade of cognition but they devise equally complex manual techniques and solve equally complex spatial problems” (Russon and Begun 2004). Apes have the abilit...
One of the species I chose to center my research paper on is the Tufted Capuchin Monkey. The Tufted Capuchin Monkey’s scientific name is the Cebus Apella Apella, yet they are also known as brown capuchin, black-capped capuchin, or even pin monkey. The Tufted Capuchin is most commonly found east of the Andes from Colombia and Venezuela to Paraguay and Northern Argentina. We find these unendangered monkeys to be living in rain forests, low montane forests, and semi-deciduous lowlands. Also, Capuchin Monkeys are found to have the widest range and broadest habitat tolerances of any other Cebus species.
After watching the TED talk from Susan Savage-Rumbaugh on “The gentle genius of bonobos” I had a great interest in the bonobo species. Before watching this video, I had already prior knowledge to the human species being related to the primate species, but never knew how closely we are to bonobos. I used to think chimpanzees were the closest but bonobos can walk in a similar movement to humans, closer than chimpanzees can. I realized how smart bonobos are, as they were able to carry out human related tasks. For example, one bonobo was able to build and start a fire in the woods. I found it interesting that the bonobo used a lighter to start the fire just like a human. Another example, was when one bonobo was learning to drive a golf cart, which
In 1960, Jane Goodall, witnessed chimpanzees using modified stick to lure out termites. Because, terminates were not visible, the chimpanzee mentally conceived that by placing the stick into the mount termites would latch onto it. The action was not genetic, young chimpanzee learned this extragenetically from witnessing adult chimpanzee’s perform the task.
Galef suggested that this behaviour was due to social learning. Given the time period, of 5 years, it is possible that other monkeys had learned this potato washing behaviour by themselves instead of imitating Imo. The observers in this experiment provided the sweet potatoes, and would pay more attention to the monkeys that washed the potatoes. This attention would be a reinforcer of the behaviour causing other monkeys to copy it. Although there is not enough supportive evidence for imitation, some behaviours ca... ...
