What is an example of allusion in the novel, Threatened?

Jane Goodall is referenced throughout the novel. First, she is used as a joke when Prof tries to explain what he is doing and Luc wonders what a "janegoodall" is. Later Prof claims to have worked with Jane Goodall in studying chimpanzees, though it is unclear if this is one of his lies or not. Jane Goodall has become a legend for her groundbreaking work in studying chimps, so a novel about people going into the jungle to study chimps would feel incomplete without referencing her. Jane Goodall is also known for being enamored with Tarzan, a man who lives in the wild among apes, which is what Luc eventually becomes.
