Did Snakes help to build the primate(मनुष्य-सदृश जानवरों का परिवार) Brain?


The deadly threat of snakes may have driven humans to develop a complex and specialized visual system. The results lend support to a controversial hypothesis: that primates as we know them would never have evolved without snakes. Snakes were “the first and most persistent predators” of early mammals, says Lynne Isbell, a behavioral ecologist the University of California, Davis. Snakes 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.
