Carl Zimmer Quotes on History (3 Quotes)

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

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.

There is so much being discovered about human origins. Five years ago, the oldest fossils of hominids were four and a half million years old. There has been a series of discoveries that pushed fossils back to six or seven million years old, which adds a couple of years to evolution history.
