Some aspects of the nutritional behaviour of the Okorobikó‐Matama (Rio Muni, West Africa) chimpanzees have been studied over two periods — from June 1963 to September 1964 and from July 1966 to February 1969. This research totaled 640 h, 119 of which were in sustained contact with the ...
1976). Bark was suggested to be a fallback or “emergency” food, based primarily on evidence that the seasonal exploitation of this resource generally corresponded with periods of staple food scarcity at the site
Overall the energetic costs of brain maintenance for modern humans are about three times those of a chimpanzee. Growth costs will also be commensurately larger.Then they consider encephalization and delayed maturation in humans (compared to apes), and conclude, based on an analysis of brain ...

The gestation period of a chimpanzee is eight months. A female gives birth to a baby of about four-and-a-half pounds. For the first three months, baby chimps are held close to the mother’s chest. Females can give birth to a baby every five to six years and are able to reproduce...
The present study aimed to compare the plant food diet of woolly spider monkeys (Brachyteles arachnoides) inhabiting Intervales State Park in São Paulo, Brazil, with medicinal plant species used by humans in the surrounding areas of the park. The diet of a group of woolly spider monkeys li...
Phytolith, stable carbon isotope, and dental microwear texture data for two individuals of Au. sediba, 2-million-year-old hominins from South Africa, show that they consumed a mostly C3 diet that probably included harder foods, and both dicotyledons (for
When first looking at a bonobo, one might assume that this animal represents a chimpanzee. Indeed, bonobos and chimpanzees share many genetic and morphological similarities. Based on genome sequencing, both bonobos and chimpanzees are considered the closest living relatives of humans, with all three ...
