Groups of people sometimes need to make decisions.Students might take a class vote on what book to read or game to play.Villagers might take a village vote to decide who will be their leader.But humans aren't the only creatures on Earth who vote.Other animals,from honeybees to baboons,make group decisions.They just do it differently,and for different reasons.Instead of voting for a leader,animals vote on where to live or when to hunt.For years,scientists have studied animals'voting patterns and how these patterns affect group decisions.
