This book wasn't what I thought it would be. Yes this book in jam packed with information, statistics and science but it also is kind of like a memoir. The author's own experience in this field of science was interesting to read about. I personally hated Biology, but to see the author zeal for it was really interesting. It shows how different we as humans can be. DNA is something was all know of, but there is a lot more to it than we know. This book will be perfect for those who took science as a elective in school, but for me I know that this book will make my brain hurt after so long. However, I do admit, I like what I've read so far.
