Children Learn by Monkey See, Monkey Do. Chimps Don't. [article]

I drove into New Haven on a recent morning with a burning question on my mind. How did my daughter do against the chimpanzees?

A month before, I had found a letter in the cubby of my daughter Charlotte at her preschool. It was from a graduate student at Yale asking for volunteers for a psychological study. The student, Derek Lyons, wanted to observe how 3- and 4-year-olds learn. I was curious, so I got in touch. Mr. Lyons explained how his study might shed light on human evolution.
