What Do Chimpanzees Eat A Primate Culinary Exploration 6

Chimps Can’t Cook, But Maybe They’d Like To

Western chimpanzees separated from the other chimpanzees around 500,000 years ago. For comparison, bonobos are only separated from them by 800,000 years. This has led some researchers to suggest Western chimps be defined as their own separate species.

The first, a bulk indent test, used a large hemispherical probe (of 3.6 mm radius) for measuring the elastic modulus of bulk food items, like fruit flesh. A sample must be cut so that is stable and has a flat surface normal to the probe. Care must be taken that the sample is sufficiently thick (≥2 mm) and that the indent does not exceed 10% of the sample thickness to avoid influence of the substrate on which it rests64. The second test is a membrane test that can be used on sheet-like materials like leaves and, in some cases, a peel-like exocarp of a fruit. A test specimen was clamped between two transparent plates that have aligned circular holes, 2 mm in radius, in their centre. A hemispherical probe of 0.25 mm radius is then used to measure the elastic modulus of a specimen—laminar leaf tissue or some external fruit peels by pressing down on a specimen exactly in the centre of the exposed disc of tissues.

They feast on a plethora of fruits such as bananas, figs, berries, and mangoes. Nuts, including almonds, walnuts, and cashews, are also relished by chimpanzees. They use tools like rocks or sticks to crack open tough shells and extract the nutritious kernels inside. 5-Variety—In considering our ancestral diets, we tend to imagine our ancestors ate “ideal” diets for their bodies. Different chimps eat different diets as a function of what they find, just as our ancestors would have eaten different foods depending on just where they lived as well as other factors. Studies of chimp diets based on carbon and nitrogen isotopes have found some chimps appear to eat exclusively plants, whereas some individuals feed a little higher on the food chain.

I did a quick count and found fewer than fifty plant species in my entire local farmer’s market. Bulk food items, such as substantial pieces of fruit flesh, had their toughness estimated by employing the wedge test. A sharp wedge (circa 15°) would be driven into a food specimen of known dimensions for a known displacement, thus generating a crack within it. A second pass, as described above, compensates for the influence of friction. The energy actually used in crack formation, obtained by deducting the work done in the second pass from that in the first, was then divided by the area of the newly created surface to obtain an estimate of the toughness61. When these circumstances arise, a single blade, or two crossing blades as in a pair of scissors, was used to propagate a crack though a material of known dimensions.
