sciencehabit writes "A new study of the monkey brain suggests that primates are uniquely adapted to recognize the features of snakes and react in a flash. What's more, by selecting for traits that helped animals avoid them, the reptiles ultimately endowed us with forward-facing eyes, for example, and enlarged visual centers deep in our brains that are specialized for picking out specific features in the world around us, such as the general shape of a snake's body camouflaged among leaves.The results lend support to a controversial hypothesis: that primates as we know them would never have evolved without snakes."
