Carl Zimmer Book Quotations

I started fact checking and copy-editing, basic stuff. Then I started writing books and articles, and left in 1999. I've been working freelance ever since and moved here three years ago.

I read a lot of scientific papers on the history of evolution and spent time talking to scientists. I started to write it in the spring of 2004 and wanted the book to look at the biggest questions people have about human origins, such as what were the first hominids and how did our ancestors evolve to walk upright?
