At the Kasakela Chimpanzee Community in Tanzania, Jane Goodall observes chimpanzees creating tools, the first-ever observation in non-human animals.

The Kasekela chimpanzee community is a habituated community of wild eastern chimpanzees that lives in Gombe National Park near Lake Tanganyika in Tanzania. The community was the subject of Jane Goodall's pioneering study that began in 1960, and studies have continued ever since, becoming the longest continuous study of any animals in their natural habitat. As a result, the community has been instrumental in the study of chimpanzees and has been popularized in several books and documentaries. The community's popularity was enhanced by Goodall's practice of giving names to the chimpanzees she was observing, in contrast to the typical scientific practice of identifying the subjects by number. Goodall generally used a naming convention in which infants were given names starting with the same letter as their mother, allowing the recognition of matrilineal lines.
