Book review – Observing Evolution: Peppered Moths and the Discovery of Parallel Melanism

7-minute read

Every student of evolution will be familiar with the peppered moth, Biston betularia. It is right up there with the Galápagos finches as an example of evolution happening right under our noses. The story of the rapid spread of dark moths in response to the soot deposition that accompanied the Industrial Revolution, and the reversal of this pattern when air pollution abated, is iconic. Yet, as Emeritus Professor of biology Bruce S. Grant shows, there are a lot more subtleties to it than my one-liner suggests. Observing Evolution details research by himself and many others, and along the way addresses criticism – legitimate and otherwise – levelled at some of the earlier research. Eminently readable, this is a personal story of the rise, fall, and ultimate redemption of one of the most famous textbook examples of evolution in action.

Book review – The Contamination of the Earth: A History of Pollutions in the Industrial Age

8-minute read

The Industrial Revolution has been a mixed blessing. Although it improved living standards and brought material prosperity to many, humanity and the environment have paid a high price, not least in the form of pollution. The Contamination of the Earth catalogues the many forms of past pollution but also examines the social and political aspects of it. In other words, how people were affected by it and responded to it, and how legislation and politics allowed it to happen, to persist, and to only grow with time. This sprawling and information-dense environmental history work does full justice to this large and serious topic, but be prepared for a read that is neither light nor uplifting.
