The book I read was "Why Evolution is True", by Jerry A. Coyne. In this book, Jerry is talking about, (You can guess by the title), why evolution is true. He also goes into depth about why it happened and the factors that caused it. He uses a very large amount of evidence and backs up all of his claims. He lists 6 main ideas in this book, they are evolution, gradualism, speciation, common ancestry, natural selection, and non selective mechanism of evolutionary change. Some interesting facts that Jerry talks about are that mutations are the main reasons for change in an organisms ability to survive.
