Carl Zimmer Ancestor Quotations

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?

I'm really interested in the history of life in general. How life began to how birds evolved to what our ancestors looked like.
