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.

Book review – Metazoa: Animal Minds and the Birth of Consciousness

7-minute read

In 2016, the scuba-diving philosopher Peter Godfrey-Smith wrote Other Minds where he explored the mind of the octopus – I reviewed it right before reading this book. Its bestseller status, including translations in more than 20 languages, was not entirely unpredictable. Octopuses are a sexy topic. Four years later, he explores animal minds further with Metazoa, with the tour now also including sponges, corals, shrimp, insects, fish, and mammals. Godfrey-Smith convinced me he is no one-trick pony when it comes to writing a good book, though this one is more cerebral than its predecessor.

Book review – Other Minds: The Octopus and the Evolution of Intelligent Life

6-minute read

Peter Godfrey-Smith is popularly known as the scuba-diving philosopher and has just published his new book Metazoa, in which he plumbs the evolutionary origins of minds. 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.

Book review – Contingency and Convergence: Toward a Cosmic Biology of Body and Mind

6-minute read

This is the final of three reviews of MIT Press books in The Vienna Series in Theoretical Biology dealing with convergent evolution, something I consider to be one of evolutionary biology’s most exciting topics. Are evolutionary changes happy accidents, i.e. contingencies? Or is there a law-like repeatability underneath, explaining why some traits evolve time and again, i.e. convergence? Is it even a matter of either-or? And what lessons does this hold for life elsewhere in the universe? Philosopher Russell Powell wrestles with these questions in a manner that is as rigorous as it is intellectually rewarding. Evolutionary biologists will want to give this excellent book a very close read.

Book review – Convergent Evolution on Earth: Lessons for the Search for Extraterrestrial Life

6-minute read

Planet Earth might just as well be called Planet Water. Not only is our planet mostly ocean, life also started out here. Following his 2011 book Convergent Evolution, palaeobiologist George R. McGhee returns to MIT Press and The Vienna Series in Theoretical Biology to expand his examination to oceanic lifeforms, with the tantalising promise of applying the insights gained to astrobiology. I was particularly stoked for this second of a three-part dive into what I consider one of evolutionary biology’s most exciting topics.

Book review – Life through the Ages II: Twenty-First Century Visions of Prehistory

6-minute read

When it comes to modern palaeoartists, Mark Witton has become a leading light in my opinion. Next to bringing a background as a professional palaeontologist to his artwork, he also wrote The Palaeoartist’s Handbook, which is a unique resource for this field as far as I can tell. Who could be better suited to produce a homage and sequel to one of the most iconic palaeoart books of all times: Knight’s Life through the Ages?

Book review – Lamarck’s Revenge: How Epigenetics Is Revolutionizing Our Understanding of Evolution’s Past and Present

As one of several intellectuals who wrote about evolution before Darwin, time has not been kind to the French naturalist Jean-Baptiste Lamarck (1744-1829). Reviled during his lifetime by the influential Cuvier, after his death he became best remembered, and ultimately ridiculed, for the idea that characters acquired during an organism’s lifetime are passed on to its offspring. With the rise of the modern field of epigenetics, some of his ideas are making a comeback, albeit modified and adapted for the 21st Century. Palaeontologist and astrobiologist Peter Ward would even like to go so far as to restore some honour to his name and consider epigenetics a neo-Lamarckian process.

Book review – Across the Bridge: Understanding the Origin of the Vertebrates

When you think of an animal, you will most likely think of a vertebrate. Since we are animals with a backbone ourselves, it is not strange that that which is closest to us comes to mind first. But when and how did vertebrates evolve? To answer that question, Nature editor Henry Gee takes a good hard look at invertebrates, convincing the reader that they are not all equal. More than 20 years ago, Gee wrote Before the Backbone: Views on the Origin of the Vertebrates, which took a look at historical explanations for the origins of vertebrates. Which group of invertebrates is closest to us remains a topic of active research and Across the Bridge brings readers up to date with our current thinking.

Book review – Earth History and Palaeogeography

This book is an example of what happens when you go down rabbit holes. I have been reading several books on the subject of palaeontology and geology lately, and I know that the face of the earth has shifted over the hundreds of millions of years of deep history covered in these books. But where were all the continents at different times? Many will have seen the iconic maps of the supercontinent Pangaea. But I want to know more. What happened in between? And before? As Nield tells in Supercontinent: 10 Billion Years in the Life of Our Planet, Pangaea was only one of several such supercontinents in Earth’s history. But I want to know more still. Where exactly were the continents located? And how did they move? Several accessible books have provided snapshots of iconic moments, such as the formation of the Himalayas (Mike Searle’s Colliding Continents: A Geological Exploration of the Himalaya, Karakoram, & Tibet) or the disappearance of the Tethys ocean (Dorrik Stow’s Vanished Ocean: How Tethys Reshaped the World). But I want to know more! This technical reference work contains lots of fantastic palaeogeographical maps that answered all my questions.
