What Do Chimpanzees Eat A Primate Culinary Exploration 8

Western Chimpanzee, Pan troglodytes verus

This research was conducted in accordance with regulations of the Uganda National Council for Science and Technology and Uganda Wildlife Authority. The study also complied with the American Society of Primatologists’ Principles for the Ethical Treatment of Non-Human Primates. “The more we study our primate cousins, the more we realise that they have the bases of most of our cognitive abilities, including for language, culture and fairness,” she said. Dr Erica van de Waal, a psychologist at the University of St Andrews, said the findings add to the growing list of parallels that have been observed between human and ape behaviours. In a final display of self-control, around half the chimps chose to hoard raw potato – setting aside up to 28 slices – when they knew they would be presented with the option of cooking it later on.

Chimps learn most of their behavior from adults when they are young (research suggests that older chimps are often unable or unwilling to learn new behaviors). Because of this, we can see marked behavioral differences not just among different subspecies, but among different groups of the same subspecies. How one Western chimpanzee collects ants can be completely different from a Western chimpanzee only a few miles away. Many chimps in captivity have lived to well over 50; however, a more typical life expectancy for a captive chimpanzee is between 30 and 40 years. In the wild, most chimpanzees that survive their infancy will live between 15 and 25 years. Chimpanzees use facial expressions to show emotions, but a human smile that shows all your teeth is seen as a threatening expression to chimpanzees.

The humanlike antics are hilarious because chimps seem so uncannily like us, yet so different. Among many, many other chimp skills, primatologists have learned that our closest evolutionary cousins fashion spears to hunt for prey, trade food for sex, play with dolls and don’t take kindly to drones invading their space. As the climate changes, ecosystems change with it, further affecting the habitats of chimpanzees. Where chimpanzees would have been able to migrate to more hospitable areas, they’re prevented by the expansion of human-occupied urban areas.

This means that direct observations of feeding can be reduced to a matter of minutes per day. Therefore, direct observations were used on an opportunistic basis and foods were collected following confirmation that a certain food item was eaten by the chimpanzees. In both sites, whenever foods were selected by humans, efforts were taken to match overt cues of readiness of foods for consumption.

Although peak fruiting periods have been registered at Kanyawara, they vary greatly between years, thus the fruiting period is not strictly linked to certain months or climate season (Chapman, Wrangham, Chapman, Kennard, & Zanne, 1999). Female chimpanzees of the Kanyawara community were observed by MU from January 2014 to June 2015. The Kanyawara chimpanzee community ranges in the northwestern sector of KNP and has been studied since 1983 (Isabirye-Basuta, 1988; Wrangham et al., 1991). At the time of this study, the Kanyawara community comprised 47 to 51 chimpanzees of which 17 were adult females. Fourteen lactating female chimpanzees who were fully habituated were selected as study subjects. Estimated ages at the start of the study were between 13.3 and 54.9 years.
