Moth An Evolution Story by Isabel Thomas

Moth: An Evolution Story by Isabel Thomas, illustrated by Daniel Egneus (9781547600205)

This nonfiction picture book explains a specific process of evolution by following the story of the Peppered Moth. The moths emerge from their cocoons after the long winter, quickly seeking shelter from predators. At first, most of the moths had speckled black and white wings. It allowed them to better hide in the bark of the woods. The ones that happened to be born with dark wings got eaten by predators. So the speckled moths were able to survive to lay their eggs. But then the world around them changed with more soot and pollution covering the bark of the trees and other objects. Now it was the dark moths that survived best and could lay their eggs. Steadily, the moths started to become darker and less speckled. Now though, pollution is lessening and there is no longer as much soot. So the speckled moths are returning alongside the dark moths.

The tale of the Peppered Moth shows many elements of evolutionary process, including natural selection and adaptation. Both of those concepts are more fully described in the final pages of the book but are fully realized in the main part of the book as well. Thomas does a lovely job with the prose, giving the reader just enough information to allow the story to unfold before them. She limits the amount of words on the page, making this accessible for quite young children.

The illustrations are marvelous, inviting readers into the darkness of a moonlit woods as the moths emerge from their cocoons. The pages fill with moths of different mixtures of black and white. When day comes, more predators enter the pages. As the pollution enters, the world becomes dark and filled with dots and specks of dirty soot. The moths glow against the new darkness, or hide well, depending on their color. It’s a stirring and rich look at evolution happening right before your eyes.

Beautifully written and illustrated, this is a very special nonfiction picture book. Appropriate for ages 5-8.
