As proofreading goes on chapter by chapter, I get my last chance to review references and properly
site cite sources. It’s slow, tedious, and so little fun, I thought I’d throw some of it at you.
The question: How many species in the history of the planet have gone extinct?
Obviously I don’t need hard data as there isn’t much: but a ripe quote from an expert, or a summary of expert opinions would be perfect.
The prize: find me a reference that I’m willing to use in the book, and I’ll put your name in the book’s acknowledgments.
