The chemical senses
Professor Pierre Lledo introduces the two main chemical senses - smell (olfaction) and taste.
They are two main chemical senses. One is called the sense of smell (or olfaction), and the other one is taste. Both of them are the oldest senses. When life started with two cells, floating in the ocean, they were looking for them by chemical changes. So this is one of the oldest senses that we know.
