       | It never occurred to me before that mammals, or specifically the
       | placental and marsupial subset, had the most developed olfactory
       | sense. Perhaps then a sense of smell is more complex to develop,
       | in evolutionary terms, than sight or hearing? A strange idea
       | indeed since sight is typically considered the most sophisticated
       | sense.
