Just Pinned to Domestic and Global News: Myth busted: People smell as well as dogs! Miami (AFP) - People's sense of smell is just as sharp as those of rats and dogs a US researcher said Thursday calling for an end to a century-old "myth" to the contrary. Rutgers University neuroscientist John McGann reviewed research and historical writings he says led to the misconception that human sense of smell is inferior according to the report in the journal Science. "For so long people failed to stop and question this claim even people who study the sense of smell for a living" he said. "The fact is the sense of smell is just as good in humans as in other mammals like rodents and dogs." Humans have long been believed capable of detecting about 10000 different odors. In fact the number is closer to one trillion McGann said. A 19th-century brain surgeon and anthropologist named Paul Broca provided the origin of the myth about humans' poor sense of smell according the Science report said. In his 1879 writings Broca cited the smaller volume of humans' olfactory area in the brain compared to other larger parts. It meant that humans had free will and didn't have to rely on smell to survive like do
