Book review – Notes from Deep Time: A Journey Through Our Past and Future Worlds

6-minute read
keywords: earth sciences

Deep time is, to me, one of the most awe-inspiring concepts to come out of the earth sciences. Getting to grips with the incomprehensibly vast stretches of time over which geological processes play out is not easy. We are, in the words of geologist Marcia Bjornerud, naturally chronophobic. In Notes from Deep Time, author Helen Gordon presents a diverse and fascinating collection of essay-length chapters that give 16 different answers to the question: “What do we talk about when we talk about deep time?” This is one of those books whose title is very appropriate.

Book review – A (Very) Short History of Life On Earth: 4.6 Billion Years in 12 Chapters

7-minute read
keywords: earth sciences, evolutionary biology

Deep time is one of the most mind-boggling yet underappreciated concepts to come out of the disciplines of evolutionary biology and the earth sciences. As an editor with Nature for over three decades, Henry Gee has had a front-row seat to numerous exciting scientific developments that have enriched our understanding of Earth’s vast 4.6-billion-year history. This high-octane popular science book is his take on the genre of the “earth biography”.

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 – Locked in Time: Animal Behavior Unearthed in 50 Extraordinary Fossils

7-minute read

Fossils can tell us what animals living in the distant past looked like. Over the centuries, palaeontologists have made incredible strides in reconstructing extinct life forms, helped along by cumulative experience, technological advances, and a steadily increasing body of rare but truly exceptionally preserved fossils. But reconstructing their behaviour—surely that is all just speculative? In Locked in Time, palaeontologist and science communicator Dean R. Lomax, with the able help of palaeoartist Bob Nicholls, presents fifty of the most exceptional fossils that preserve evidence of past behaviour: from pregnant plesiosaurs to a pterosaur pierced by a predatory fish. I was eagerly awaiting this book from the moment it was announced, but I was still caught off-guard by some of the astonishing fossil discoveries featured here.

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 – Cataclysms: An Environmental History of Humanity

6-minute read

What is the price of humanity’s progress? The cover of this book, featuring a dusty landscape of tree stumps, leaves little to the imagination. In the eyes of French journalist and historian Laurent Testot it has been nothing short of cataclysmic. Originally published in French in 2017, The University of Chicago Press published the English translation at the tail-end of 2020.

Early on, Testot makes clear that environmental history as a discipline can take several forms: studying both the impact of humans on the environment, and of the environment on human affairs, as well as putting nature in a historical context. Testot does all of this in this ambitious book as he charts the exploits of Monkey—his metaphor for humanity—through seven revolutions and three million years.

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

6-minute read

Following my two earlier reviews of Convergent Evolution and Convergent Evolution on Earth, 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 – A Life on Our Planet: My Witness Statement and a Vision for the Future

8-minute read

The legendary British broadcaster and natural historian Sir David Attenborough needs almost no introduction. Since his first appearance on our television screens in 1954, he has gone on to a long and distinguished career presenting and narrating groundbreaking nature documentaries. And he shows no sign of slowing down. His voice and style have become so iconic that he has been dubbed the voice of nature. Over the years, he has increasingly expressed concern over the state of the natural world, and in A Life on Our Planet Attenborough fully engages with this topic. However, when you turn to the title page you will notice the name of a co-author, Jonnie Hughes, who directed the Netflix documentary tied in with this book. As Attenborough explains in his acknowledgements, Hughes has been particularly instrumental in the writing of the third part of the book, together with substantial assistance from the Science Team at WWF. This is Attenborough’s witness statement, yes, but whose vision of the future is it?
