The Max Planck Institute tested children and chimps in their willingness to cooperate in helping another person with a task. This video from The Human Spark shows that while chimps were as willing as children to help in reaching tasks, children helped with a wider range of tasks and seemed to enjoy participating. Children also differed from chimps as once they were taught how to perform a task, not only did they teach others, they insisted the task being performed in the exact way they were taught.
