Ancestral & Weird Senses
Season 1
Episode 8
We talk about one of the earliest animal senses, - chemosensation -- or our sense of taste and smell. We discuss how animals use these senses to explore their environment and communicate, and how that pair of nostrils of yours is an example of convergent evolution. And, witness how some animals have the ability to sense electric and magnetic fields.
