Think primates are all sunshine and rainbows and cuddle piles? Think again. Chimpanzees, our closest living relatives, have an incredible capacity for cognition, culture, and calculated violence. They use tools, teach region-specific techniques to their children, follow strict social rules, and, as evidenced by the great Four Years War in Gombe, Tanzania, are capable of intense, prolonged, inter-group conflict. Learn all about the war in this episode of Primates. Follow us on instagram @the.primates.podcast for more!
