The researcher hypothesizes that bonobos eat Manniophyton fulvum leaves during the rainy season because they have medicinal properties. For evidence, he points to one such property: the leaves help eliminate gastrointestinal worms.
The researcher assumes bonobos eat Manniophyton fulvum leaves because of their medicinal properties, and not for some other reason. This means assuming bonobos benefit from having fewer gastrointestinal worms and that the leaves are not worth eating just for their nutritional value.
