Bonobos are an endangered species of great apes that are closely related to humans and chimpanzees. Similar in many respects to chimps, bonobos are notably smaller, more socially cooperative, and less aggressive. Playing a major role in the dispersal of seeds, these creatures provide an essential service to their ecosystem. As one will see, their anatomy is very similar to other apes, especially chimpanzees. However, there are some minor anatomical features that are more similar to that of humans. In addition, hormones in relation neuroendocrine function may play a major role in the way these apes go about social bonding. Unfortunately, bonobos face many threats. These threats include poaching and deforestation, with an emphasis on poaching to support bushmeat trade. Our mission is to provide public awareness and education in relation to these endangered primates. As you progress through this site, you will explore the evolutionary history, conservation, ecology and biology that set these primates apart from the rest of the great apes, including humans. To aid in understanding key terms and concepts, links have been provided to direct the learner to encyclopedic resources. Finally, an extensive list of references and supplementary material has been provided, with both in-text citations and a formal bibliography (listed under References).
