I have a B.S. in Biology and found this book to be in-depth science told in an easily readable way. If you are a layman who is keenly interested in everything science, than this book will seamlessly bridge that gap.
You will learn about the gene for lactose tolerance, why and when it came about, and what it means about homo sapiens history. Best of all, it will be conveyed in a gripping manner that feels more like entertainment than learning, which aids tremendously in retention.
As a whole, what you will get is the story of Homo sapiens rise over the last 200,000 years. As our amazing journey from quaint beginnings to global hegemony unfolds you'll learn how and why we know what we know about our history.
