Ebook: What Evolution Is: From Theory to Fact

I thought this was a great book for someone who's already in the field of evolutionary biology or even physical anthropology. It's a bit too much to pick up without knowing anything about evolutionary theory, and although it's supposed to be for a layman, he relies on quite a lot of technical talk. Otherwise, this is an excellent resource for anyone who wants to know about many of the scientific discoveries in evolution, and it will bring the reader up to speed on the current state of the science. Ernst Mayr is an unparalleled authority, and well worth reading.
