Aresearcher raises a sample of unrelated macaque monkeys in identical laboratory environments. he finds large differences among these monkeys in their preference for novel visual stimuli. what might the researcher legitimately conclude concerning the relative contributions of nature and nurture to the preference for visual novelty?

The answer to this question is Nature contributes substantially to the monkeys' preference for visual novelty.
It's very important for monkey to utilize thier visual novelty in order to gather enough foods and avoid predators in the jungle. Humans needs no such things because we just use our visual capability to navigate without having to worry about foods or predators.
