Majority Rules for Toddlers and Chimps

A new study reflects our previous talks on evolution in class.  2-year-olds and chimpanzees are more likely to copy actions when they see them repeated by three of their peers than if they see the same action done by one peer three times. Many wouldn't expect this behavior out of children at such a young age. In the study, orangutans, chimpanzees, and human children observed while others of their same species interact with a box that had three different colored holes in it. The chimps and humans were more likely to choose the same one as their peers after their observations, while the orangutans behavior was at random.
