Evolution is one of the most misunderstood scientific theories. Simply put, it’s the change in the characteristics of a species over several generations. Yet, people still argue over the idea that humans share an ancestor with an orangutan, for example. This valuable volume explains evolution, natural selection, and basic genetic concepts through accessible language, instructive examples, and enlightening images. While the critical work of Charles Darwin is a focus, the text also highlights the contributions of many other scientists whose work predated the famous expedition to the Galapagos Islands as well as those whose discoveries have since helped bolster the theory of evolution by natural selection.
