Book review – Explorers of Deep Time: Paleontologists and the History of Life

6-minute read

When I ask you to think of a palaeontologist, what comes to mind? Admit it, you likely thought of someone digging up dinosaur fossils. And that someone was probably a white man. Grounded in the past, and endlessly repeated in the present, this is of course a very narrow picture of what palaeontology is like. In Explorers of Deep Time, Roy Plotnick, a palaeontologist and emeritus professor in earth and environmental sciences, challenges this and other stereotypes. Pardon the excruciating pun, but he leaves no rock unturned in the process of showing the many faces of modern palaeontology.

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.
