Book review – The Earth: A Biography of Life

6-minute read

I have previously jokingly called the “Earth biography” a rite of passage for science writers; many authors try their hand at it at some point. Fortunately, the Earth is big and time is deep, so there are numerous ways to tell this story. Here, it is palaeontologist Elsa Panciroli’s turn. Next to many unusual examples by which to tell the story of life’s evolution, her writing stands out for correcting common misconceptions and for its inspired language.

Book review – The Greywacke: How a Priest, a Soldier and a Schoolteacher Uncovered 300 Million Years of History

7-minute read

Take a look at the geological time scale*. Thanks to the dinosaurs, we have all heard of the Cretaceous, Jurassic, and Triassic. However, going back in time from the Triassic, the Phanerozoic Eon in which we live today stretches another 289 million years into the past; from the Permian that ended ~252 million years ago, through the Carboniferous, Devonian, Silurian, Ordovician, to the Cambrian that started ~539 million years ago. In The Greywacke, amateur geologist Nick Davidson tells the story of how those geological periods got their names and transports the reader back to the heydays of Victorian geology when three men would make Britain’s rocks the centre of international attention. In so doing, he unlocks for a general audience an episode in the history of geology that was so far consigned to more technical literature.

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

6-minute read

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 – Dinosaurs Without Bones: Dinosaur Lives Revealed by Their Trace Fossils

6-minute read

Say “dinosaurs”, and most people imagine fossilised bones and spectacular museum displays. But body fossils are not the only remains we have with which to reconstruct dinosaur lives. Nor, and this might sound controversial, are they the most important. Or so argues palaeontologist, geologist, and ichnologist Anthony J. Martin. Ichnology is the study of animal traces, whether modern or fossilised. Most traces are ephemeral and disappear within hours or days, but occasionally some are buried and end up in the fossil record. With tongue firmly planted in cheek, and with more puns than you can shake a T. rex thigh bone at, Martin forays into the rich dinosaur trace fossil record: from footprints, burrows, and nests, to teeth marks and fossil faeces. For all the jokes, and despite having been published in 2014, he raises some really interesting points.

Book review – Ancient Bones: Unearthing the Astonishing New Story of How We Became Human

7-minute read

Where do humanity’s evolutionary roots lie? The answer has long been “in Africa”, but this idea is being challenged from various sides. I previously reviewed Begun’s The Real Planet of the Apes as a warming-up exercise before delving into this book. My conclusion was that its discussion of archaic ape evolution, although proposing that species moved back and forth between Africa and Eurasia, ultimately did not really challenge the Out of Africa hypothesis. Not so Ancient Bones. German palaeontologist Madeleine Böhme, With the help of two co-authors, journalists Rüdiger Braun and Florian Breier, firmly challenges the established narrative in an intriguing book that is as outspoken as it is readable.

Book review – Volcanotectonics: Understanding the Structure, Deformation and Dynamics of Volcanoes

7-minute read

We all have a pretty good idea of what a volcanic eruption looks like, but they are only the surface expression of a much larger and longer underground process that is hidden from view. The internal workings of a volcano, its plumbing if you will, are studied by the relatively new scientific discipline of volcanotectonics. Icelandic volcanologist Agust Gudmundsson has been researching and teaching this topic for two decades and here delivers the field’s first textbook. In preparation, I beefed up my knowledge base by first reviewing a introductory volcanology textbook, but it almost was not necessary – Volcanotectonics turned out to be exceptionally instructive and accessible.

Book review – Volcanoes (Second Edition)

7-minute read

Volcanoes are some of the most awe-inspiring natural spectacles on our planet. There is much more to them, though, than the stereotypical image of a conical fire-spitting mountain, and I have been keen to learn more. As I searched for serious introductory books on volcanology, this was one title that kept coming up. But wait, why is a biologist reviewing geology textbooks?

Book review – Origins: How the Earth Made Us

Origins asks one question: how did the Earth make us? More accurately, like a six-year-old whose curiosity cannot be sated, there lies a series of recursive “why” questions at the heart of this book. Astrobiologist and science communicator Lewis Dartnell takes a big history look at human evolution and especially civilization, seeing how far down the explanatory rabbit hole he can go. Time and again, he grounds his answers in geology and geography. You would be forgiven for thinking this sounds like what Jared Diamond attempted more than two decades ago, but calling it Diamond-redux would not do it justice.

Book review – Structural Geology (Second Edition)

Planet Earth’s many landforms can be breathtaking to behold. Plate tectonics has given us a basic framework to explain their formation, but there is far more to this story than that. I recently mentioned wanting to learn more about geology, having shunned the subject in favour of biology at university. So, fascinated by photos of folded rocks that look like so many layered cakes that had an accident in a bakery, and freshly armed with some basic knowledge of geology after my recent review of Essentials of Geology, Haakon Fossen’s Structural Geology seemed like a good starting point to deepen my knowledge further.
