Isabel Thomas and Daniel Egnéus
Bloomsbury Children’s Books
Interestingly this is the second picture book introducing adaptation and natural selection to children I’ve seen in the past few weeks – could a new trend be starting. I was first taught about these scientific ideas with reference to the Peppered Moth, the particular example used in this story, when doing A-level zoology donkeys ages ago, and now they’re part of the KS2 science curriculum – quite a thought.
‘This is a story of light and dark. Of change and adaptation, of survival and hope.’ So says science writer, Isabel Thomas in the opening lines of her narrative, a narrative that seamlessly interweaves both science and social history.
In the nineteenth century almost all Peppered Moths had light grey patterned wings that blended with the tree trunks and branches it frequented.
With the coming of the Industrial Revolution also came air pollution blackening buildings, monuments and trees alike.
In this new environment, the light-coloured moths became easy to spot and were gobbled up by birds.
Darker forms of the insect were less conspicuous and more likely to escape predation and to breed whilst the lighter form became extremely scarce.
With the advent of the Clean Air Acts in the mid-twentieth century air pollution from smoke and soot was greatly reduced, trees and buildings were no longer stained. Now the dark moths were more conspicuous and less likely to breed successfully, though both forms of the moth can still be found.
All this, Isabel Thomas recounts in her dramatic, sometimes lyrical text that ends with hope. A hope which, as we hear in the final explanatory pages, might lead to other living things being able to adapt to the changes, including climate change, that we humans inflict upon our planet.
Daniel Egnéus’ illustrations are as lyrical as the text, embodying at once arresting beauty and veritas, and instilling a sense of awe and wonder. It’s rare to see such an eloquent science-focused book that also embraces the arts side of the curriculum.
