One Iguana Two Iguanas: A Story of Accident, Natural Selection, and Evolution
Author: Sneed B. Collard III
Publisher: Tilbury House Publishers, 2018
Interested in evolution and how natural selection develops and favors those animals (in the case of this book, lizards) who adapt more readily to changes in the environment? Pick up this book, which explores the theories of Charles Darwin!
This subject could seem boring to young readers, but this book approaches the topic in a fresh way. Instead of starting with an overall explanation of evolution, it gets specific. It starts with one marine iguana diving below the water’s surface to munch on algae. Nearby a land iguana sits guarding its dinner – a prickly pear cactus. As the excellent photos show, the iguanas are quite different. Yet both live on the Galapagos islands. How did they get to be there? How did they become so different?
As the book continues, we learn how these barren volcanic islands were formed and how life (plant and animal) arrived there. Although some of the information is conjecture, the text explains how scientists have researched the subject.
Each page is filled with wonderfully, detailed photographs of the inhabitants of the Galapagos islands: lizards and birds and turtles. Many of the pages also include inset photos of details, things like the tricuspid teeth of the marine iguana or a blue-footed booby diving for fish.
This book is part of the How Nature Works series. Look for my recent review of Don’t Mess With Me for another book in the series
