I want to be David Quammen when I grow up. He’s a professional writer who spent most of his life getting paid by magazines like National Geographic and Outside to go on adventures and write about them. He’s written about crows in Seattle, corpse fruit in the Pacific and hiking through the Congolese jungle. More recently, he finished a fun and compelling biography of Charles Darwin. Here we have him addressing Case Western University as part of the Darwin Year lecture series. It’s longer, but worth it. The man is as engaging a speaker as he is a writer.
