Take the following as truth: Robert Wright  Anyone who doubts that male chimpanzees spend lots of time fighting over females should read Frans de Waal's book Chimpanzee Politics . Though the chimp colony de Waal studied was not in a purely natural setting, as were the chimps at Gombe studied by Jane Goodall, de Waal, for that very reason, got a clearer look at daily life within a colony than Goodall did.
Then the following statement: "The chimp colony de Waal studied was not in a purely natural setting" is true, false, or inconclusive?
Answer: True
