Rob Sears is a copywriter at McCann Erickson advertising agency, has written comedy and fiction for McSweeney's and (with his brother Tom) wrote a sitcom for Audible starring Kevin Eldon, Felicity Montagu and Mitch Benn. He lives in Finsbury Park with his wife.

Rob and Tom's creative partnership began in the 1980s when Tom (the younger brother) was born. Now, Rob is a bestselling author and Tom is an illustrator. They've created everything from zoo exhibitions and ice cream van designs to sitcoms, newspaper cartoons and movie scripts. They made this book as an experiment to try to understand the species that they are a part of, and that you're most likely a part of too. Despite everything they learned, they're still hopeful about what's next for humans and the planet.
