What is the most interesting similarity between humans and chimps? What is the most interesting difference? For evidence accepted as scientific, it must be empirical (based on observations), public (even your worst enemies are invited to watch you demonstrate it, or to try it for themselves), and repeatable (anybody who does what you did should get the same results that you got, nearly every time they try it). Identify one example of something that the scientists in this video program did to make their evidence accepted as scientific, rather than just one person’s personal opinion. Specifically, explain how your example of the way they collected the observations makes those observations (A) empirical, (B) public, and (C) repeatable.
