Book review – Mammalian Paleoecology: Using the Past to Study the Present

7-minute read

Scottish geologist Charles Lyell quipped that the present is the key to the past. To say that the reverse also holds is more than just circular reasoning. Felisa Smith, a professor in ecology and evolutionary biology, studies extinct mammals and applies this knowledge to the present. This book is a neatly crafted package that gives the reader all the required background knowledge, while its case studies make for fascinating reading. (Spoiler alert: packrat middens are my new favourite discovery.)

Book review – Life as We Made It: How 50,000 Years of Human Innovation Refined – and Redefined – Nature

7-minute read

Books can be like buses: nothing is written on a topic for ages and then two books appear in quick succession. The subtitle of Life as We Made It resembles that of the recently-reviewed Life Changing. Both books indeed cover the same topic: how humans have shaped the genetics and evolution of plants and animals around them. Despite some inevitable overlap, Beth Shapiro draws on two decades of her career as a geneticist to make Life as We Made It a beast all of its own. I found myself both thoroughly enjoying her fantastic science communication while disagreeing with her outlook.

Book review – Life Changing: How Humans Are Altering Life on Earth

7-minute read

Ever since humans appeared on the scene, we have been altering life on Earth. Where once our actions could be considered part of nature’s fabric, our influence has become outsized and our options to exercise it have multiplied. Though the subtitle of Life Changing does not make it explicit, science writer Helen Pilcher focuses on our impact on the genetics and evolution of life around us. A book that stands out for its balanced tone, it managed to surprise me more than once, despite my familiarity with the topics considered.

Book review – Catastrophic Thinking: Extinction and the Value of Diversity from Darwin to the Anthropocene

7-minute read

The idea that extinction is a bad thing and diversity a good thing seems self-evident to us. But, by surveying more than two centuries of scholarship, science historian David Sepkoski shows that this was not always the prevailing belief. Rather than a book discussing mass extinction, Catastrophic Thinking is more meta than that, discussing how we have been discussing mass extinction. So, we have an interesting premise, but also an interesting author because—bonus detail—the work of his father, J. John (Jack) Sepkoski Jr., was instrumental in recognizing the Big Five mass extinctions. I could not wait to get to grips with this book.
