The Subterranean World Beneath Our Feet

Just when it feels like there are few places left on the earth  unexplored, Professor Anthony Martin says all you have to do is look down to discover some of nature's deepest, darkest secrets.

For hundreds of millions of years, thousands of species have sought shelter and safety underground. And the traces of tunnels left by creatures from dinosaurs to earthworms tell the story about us, and how humans became top of the food chain.

Dr Anthony Martin's book is called The Evolution Underground: Burrows, Bunkers and the Marvelous Subterranean World Beneath Our Feet.
