Island Biogeography with Kevin Alison and John Knapp
Humans have been fascinated by islands since the writing of the earliest works of literature, but the outsized role they play in our imaginations isn't limited to fiction. Islands make up only a tiny percentage of the land on earth, but they represent about a fifth of the planet's total biodiversity.
And things stranger than fiction happen on islands, from the evolution of miniature mammoths and enormous flightless birds with no fear of humans to the illumination of the theory of evolution itself.
Join me and two experts, Kevin Alison and John Knapp, as we trundle along island roads deep into the unique ecology of Santa Catalina Island and discuss giant buckwheats, tiny foxes, and what islands have to teach us about the living world back on the mainland.
