Tells the story of how the science of classification has revolutionized the way we look at life on our planet.

Did you know that you are more closely related to a mushroom than to a daisy? That dinosaurs are still among us? That the terms "fish" and "invertebrates" do not indicate scientific groupings? All this is the result of major changes in classification. This book diagrams the tree of life according to the most recent methods of this system.

Explains how animals are classified into different categories according to physical, behavioral, and biological characteristics, from the largest branch to the smallest.

Through simple yet engaging language and detailed images and charts, readers will explore the work of Aristotle, Linnaeus, Darwin, and other well-known, and some not so well-known, figures throughout history who tried to make sense of the natural world, as well as the breakthroughs and technologies that allow scientists to study organisms down to the genetic level. This book supports the Next Generation Science Standards on heredity and biological evolution by helping students understand how mutations lead to genetic variation, which in turn leads to natural selection. In addition, informative sidebars, a bibliography, and a Further Reading section with current books and educational websites will allow inquisitive minds to dive deeper into the evolutionary relationships among organisms.

How can we organize and name all of the different animals and plants in the world? Many had tried before, but Carl Linnaeus came up with a system that we still use today. This Swedish scientist from over 300 years ago is known as the father of classification. Linnaeus’s system gave each plant or animal just two names. For example, the scientific term for human beings is Homo sapiens. In Latin, Homo means "man" and sapiens means "wise."

This book is a comprehensive introduction to the philosophical foundations and development of modern biological classification.
