Networks of long-distance female friends help gorillas move between groups

"I'm not going if I don't know anyone"—sound all too familiar? Well it's not just humans. Socializing in a new group can be tricky. People often rely on word of mouth and friends-of-friends connections. New research on gorillas suggests they may be using a similar strategy: when moving to a new social group, female gorillas seek out groups containing females they have lived with in the past.
