Description: Listen to the first three episodes of Eons: Mysteries of Deep Time: podcasts.apple.com/us/podcast/eons-mysteries-of-deep-time/id1610360633 While sour taste's original purpose was to warn vertebrates of danger, in a few animal groups, including us, its role has reversed. The taste of danger became something it was dangerous for us to avoid.
