Every animal that lives in groups has to make decisions as a group. Even a seemingly simple decision like "where should we go for dinner?" can be complicated to negotiate.    Is there a simple rule behind how humans and other animals make group decisions? Margaret Crofoot is a primatologist and Leakey Foundation grantee whose research on baboons suggests there is a rule, and it's not what you might think.   You can read more about Margaret Crofoot's research and see a video of her GPS data on our blog!   Links   Margaret Crofoot's Lab   Shared decision-making drives collective movement in wild baboons   Sponsors   Origin Stories is a project of The Leakey Foundation.
