(Nagoya University) Nagoya University researchers confirmed that humans are more able to identify snakes than other harmless animals in partially obscured conditions. They used a special tool to create a series of increasingly blurry images that uniformly camouflaged different animals. The results showed that human subjects could identify snakes in more degraded images, confirming that strong visual acuity for the recognition of these dangerous animals has evolved over the course of human/primate history.
