Chimpanzee Communication Name Date Thesis Chimpanzee communication has been viewed as the “fossils of human language.” The communication systems of chimpanzees including both verbal and non-verbal demonstrate many similarities with human language. These similarities point to how and why the human language was formed. Chimpanzee’s non-verbal communication systems are strikingly similar to humans. Hugging, kissing, and hand holding are among the very human-like forms of communication that chimpanzee’s exhibit. Anthropologists are even finding that their verbal communication systems have some similarities to human language and point to human languages’ primitive beginnings. Although many have thought that communication both verbal and non-verbal is unique only to humans, scientists are finding major similarities in both areas of communication. By looking at humans past by examining chimpanzees, our closest relative, we are finding great insight into our primitive language beginnings. Annotated Bibliography Crockford, C., & Boesch, C.

This source is a study of specific calls of chimpanzees from the Tai Forest and the Ivory Coast. It talks about how combinations of barks, screams, and in some areas drumming might be linked to the beginning of human language. They reference the two components of human language: phonological and lexical syntax. This source points out the 1 phonological syntax is the stringing together of sounds according to certain rules and that lexical syntax involves strings of words with an advanced set of rules. They point out that chimpanzees use a primitive form of phonological syntax in the long distance calls that they make to locate others in their group. However they also found that some form of lexical syntax might be relevant in the case of combinations of barks and tree drumming. As well as communicating to find the location of others call combinations were found to represent a variety of other feelings as well. This source also gives a lot of information about the frequency of the calls and for what purposes. This source will be extremely helpful and is one of the most unique sources I found. It is the only source that specifically discusses how chimpanzee’s communications are the “fossils of human language.” This source seems fairly objective because they are comparing different groups of chimpanzees that are from different areas as well. It provides really nice charts of the different types of calls and what they mean that will be really interesting to include in my PowerPoint. The goal of this source was to examine chimpanzee communication and try to understand it in terms of the evolution of human communication. Fouts, R. (1997). Next of kin: What chimpanzees have taught me about who we are. New York: William Morrow and Company, Inc. This source talks about a relationship that the author had with a particular chimpanzee named Washoe. He talks about the importance of non-verbal communication and the importance it has on communicating with both primate as well as human communication. He says that non-verbal communication is just as important as verbal and in with 2 chimpanzees in that facial expressions and body language play just as big of a role in chimpanzee communication as they do in human. The author also discusses how he taught the chimpanzee Washoe sign language as well as others in which they were able to communicate amongst one another. This source is extremely interesting as it give a picture of just how intelligent chimpanzees really are. This source also asks the question of whether or not this is really language. This source gave my project an understanding of both chimpanzees that were brought up in the wild and those that were not. This particular source gives me insight into chimpanzees who were taught sign language by humans and what they can learn under instruction. This source will be useful because my other sources are about wild chimpanzees. This source may be somewhat biased because it seems to focus mainly on one chimpanzee; however it gives a good picture of the nonverbal communication capabilities of chimpanzees. I will also be able to use this source because the author discusses those who felt that chimpanzee communication and human communication cannot be compared. It has changed my project a little bit in that I will also discuss the capabilities of chimpanzee communication outside of their natural habitat. Wilson, M.L., Hauser, M.D., & Wrangham, R.W. (2007). Chimpanzees (Pan troglodytes) modify grouping and vocal behaviour in response to location-specific risk. Behaviour 144(12), 1621-1653. http://dx.doi.org/doi:10.1163/156853907782512137. This particular source talks about the use of communication during times in which other groups are encountered and warfare could potentially ensue. It talks about how less verbal communication is used so that the other side will not here them intruding. Also this source talks about how generally these groups are generally 3 male dominated leaving the females behind. This source also gives a number of how many chimpanzees normally live together in a group. It talks about how pant-hoots are used predominately by males. This source provides much less information than the other sources that I found; however it is interesting because it gives insight to chimpanzee’s communication techniques during times in which they encounter other groups. Also they have developed a system in which they keep quiet so that the other side does not hear them. This source also talks about what the pant-hoots may be used for and during what times of the day. I can use this source in relation to my argument because it examines the communication of chimpanzees during times of warfare and also how they act is very similar to humans. 4
