Episode notes

Paleontologist Henry Gee humorously explains to us why the anus was the key to large animals evolving, how the large size of our “dangly bits” is unique to our species, and what exactly has been the significance to humans about bipedalism. Our colorful discussion with Henry hilariously highlights many of the mysteries surrounding our life on earth.

"The anus was the key to all intelligent life, which is why one tends to have one's best ideas while sitting on the loo." ~ Henry Gee

Henry describes himself as a “recovering paleontologist”, but he is also an author, and a musician. His day job is the senior editor of the scientific journal Nature.

Having written numerous books, including The Accidental Species, The Science of Middle-Earth, Jacob's Ladder and In Search of Deep Time, Henry protested to his publisher that he wouldn’t write another [expletive] book. But Henry wrote another [expletive] book and we’re so glad he did! A (Very) Short History of Life On Earth is a fun and informative review of the delicate balance that has allowed life to survive and flourish on the planet.
