Stripes do little to protect zebras from predators, reigniting the age old mystery of why they have evolved to have such distinctive markings. It was thought that zebra stripes, while not concealing a target, would impede an attacker's perception of its movement.
However humans playing the part of predators in a simulated chase were found to be able to 'capture' striped targets more easily than those coloured a uniform grey. It had been thought that zebras had evolved to have stripes capable of 'dazzling' predators chasing animals moving in a group.
