Different social animals have different social structures. Wolves generally live in family units, led by the parents. Wasps and gorillas have complicated group politics, with alliances, betrayals and backroom deals. Some primitive ants have a ‘might is right’ system, with the strongest becoming the queen and fighting off challengers. Most ants have a highly democratic system, with decisions made using chemical ‘votes’ (cast by the workers; drones and queens don’t have a say).
