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.

Emeritus Professor William Eberhard has taken on that colossal task, based on his nearly 50 years of observing spiders and their webs. Some works go on to define their discipline. Spider Webs has all the trappings of becoming the arachnological benchmark for many years to come.

In preparation for reviewing that book, I am (finally) turning my attention to his initial 2016 bestseller Other Minds. Here he beholds the octopus, only to find that, behind those eight tentacles, an intelligence quite unlike ours beholds him in turn.
