In many animal societies, individuals of one sex, or sometimes both, eventually leave their birth group to join another. In a smaller number of species, including humans and gorillas, individuals can change between groups multiple times. This process, known as dispersal, plays a key role in avoiding inbreeding, spreading gene diversity and shaping social relationships. But how do individuals choose where to go?
