If you want to study chimps for whatever reason, ok I guess. But spending 10 years observing and then making up theories that seem like they were formulated in 5 minutes tells me that most of what these people are doing is a complete waste of time. And trying to find some corollary between the chimps and human behavior is absurd.
Go to the ant, thou sluggard; consider her ways, and be wise. - Proverbs 6:6
