Hypothesis

Human populations will spend less time grooming than expected based on nonhuman primate patterns (2).

Note

Observed grooming time was lower than expected based on primate patterns, but when including all hygienic behaviors (not just grooming other individuals), observed grooming time was only slightly lower than predicted.
