Social or stinky? New study reveals how animal defenses evolve
Some animals are "eww" while others are "aww." Why do some animals use stinking secretions for defense, while others are social? In a new study, researchers found that noxious spraying was favored by animals that were nocturnal and mostly at risk from other animals, while sociality was favored by animals that were active during the day and potentially vulnerable to birds of prey.
