If you spot a rhinoceros or hear an avalanche speeding toward you, auditory looming will motivate you to jump out of the way now rather than wait until the last second. The evolutionary benefits of immediately getting out of the way of approaching dangers were so strong that natural selection endowed us ― and other mammals ― with brains that ________________________________.
