There are concrete evidences of chimpanzees in wild part of Tanzania do intake Vernonia amygdalina, which possess anti-parasitic properties and hence helps in treatment of parasitic infestations.
Explanation:
On critical scientific analysis of vernonia amygdalina, it is observed that vernonia contains various lactones and glucosides steroids which showed anti-parasitic property. But the self medication hypothesis is not at all agreeable. Because chimpanzees don't have such brain to judge which things has medicinal values or from which infections or diseases they are suffering.

Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition.
Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding.
Some examples of natural selection include the selection of long-necked giraffes and the changes in the size and shape of beaks of birds according to their feeding habits.
Some examples of artificial selection include dog breeding to produce new breeds of dogs and cross-breeding in cash crops like wheat and rice.
