Part of the reason for the evolutionary success of primates, human or otherwise, is that we are a pretty smart collection of animals. What's more, our thumbs work in particularly fancy and advantageous ways, and we're more flexible about food than most. But our primate essence is more than just abstract reasoning, dexterous thumbs, and omnivorous diets. Another key to our success must have something to do with this voluntary transfer process, this primate legacy of feeling an itch around adolescence.
