Zebra Stripes: Theories and Facts

The video explores the mystery of zebra stripes, discussing various theories about their purpose. Initially, the camouflage theory suggested stripes help zebras evade predators. However, this theory faced criticism due to zebras being common prey. The thermoregulation theory proposed stripes help in cooling, but experiments showed minimal effects. The biting fly theory, gaining traction, suggests stripes deter biting flies, supported by experiments showing fewer flies on striped models. Despite ongoing research, the exact reason for zebra stripes remains a topic of scientific debate.
