Animal brains 'hard-wired' to recognize predator's foot movements, Queen's study suggests

The reason people can approach animals in the wild more easily from a car than by foot may be due to an innate "life detector" tuned to the visual movements of an approaching predator's feet, says Queen's University psychologist Niko Troje. "We believe this visual filter is used to signal the pr...
