"For a long time, scientists have tried to figure out what separates us from animals. For example, one early hypothesis was our use of tools-until Jane Goodall famously recorded observations of chimpanzees making and using tools. In fact, it looks like the very things that we once thought distinguished humans, our creativity, our ingenuity, our capacity of planning or abstract thought, are the very things that actually make us very animal!"
