Book review – Mysteries of the Deep: How Seafloor Drilling Expeditions Revolutionized Our Understanding of Earth History

7-minute read
keywords: earth sciences, history of science, oceanography

Many advances in the earth sciences have come from one particular feat of technology and engineering: deep-sea drilling. Or to be more precise, it is the sediment cores thus extracted from the seafloor that have offered a wealth of information. In Mysteries of the Deep, retired geologist James Lawrence Powell gives a very readable whistlestop tour of the many remarkable insights these drilling expeditions have given us. In the process, he provides a microcosm of how science advances and how scientists change their minds, or sometimes fail to, in the face of new evidence.

Book review – The Sediments of Time: My Lifelong Search for the Past

6-minute read

In the field of palaeoanthropology, one name keeps turning up: the Leakey dynasty. Since Louis Leakey’s first excavations in 1926, three generations of this family have been involved in anthropological research in East Africa. In this captivating memoir, Meave, a second-generation Leakey, reflects on a lifetime of fieldwork and research and provides an inspirational blueprint for what women can achieve in science.

Book review – Marvelous Microfossils: Creators, Timekeepers, Architects

5-minute read

Say fossils and what comes to mind are the big, the bad, and the sexy: dinosaurs, pterosaurs, marine reptiles—in short, macrofossils. But perhaps more important and certainly more numerous are the microfossils. Fossils so small that you need a microscope to see them. In this richly illustrated book, French geologist and micropalaeontologist Patrick De Wever offers bite-sized insights into a discipline that rarely gets mainstream attention but undergirds many human endeavours.

Book review – The Journeys of Trees: A Story about Forests, People, and the Future

6-minute read

We tend to think of forests as static. Trees, after all, do not move. But that is a perspective foisted upon us by our limbed existence. Science reporter Zach St. George unmasks this illusion in plain terms: when trees die or new ones sprout, the forest has moved a bit. “The migration of a forest is just many trees sprouting in the same direction” (p. 2).

There is no shortage of books on trees, but this sounded like such an unusual take on the subject that I was utterly stoked when I learned of The Journeys of Trees. A journalist who delves into the palaeontological record to consider the slow-motion movement of forests over deep time? Get in here!

Book review – Tree Story: The History of the World Written in Rings

7-minute read

To figure out how old a tree is, all you have to do is count its rings, and some truly ancient trees grace the pages of this book. But, as tree-ring researcher Valerie Trouet shows, that is the least fascinating thing you can derive from wood. Revealing the inner workings of the academic field formally known as dendrochronology, Tree Story is an immersive jaunt through archaeology, palaeoclimatology, and environmental history. A beautifully written and designed book, it highlights the importance and usefulness of tree rings in reconstructing past climate and linking it to human history.

Book review – The Story of the Earth in 25 Rocks: Tales of Important Geological Puzzles and the People Who Solved Them

Judging by the title of this book, you might expect it to talk of 25 remarkable kinds of rocks and minerals. But in the preface, geologist and palaeontologist Donald R. Prothero makes clear that his book looks as much at famous outcrops and geological phenomena. Bringing together 25 readable and short chapters, he gives a wide-ranging tour through the history of geology, celebrating the many researchers who contributed to this discipline.

Book review – Carboniferous Giants and Mass Extinction: The Late Paleozoic Ice Age World

Not so long ago, the idea that giant reptiles once roamed the earth was novel, unbelievable to some, but their reign represents only one part of deep time. Go back further in time, to the Carboniferous (358.9 to 298.9 million years ago), and you will find a world of giants as bizarre and otherworldly as the dinosaurs must have once seemed to us. A world where clubmoss trees grew up to 50 metres tall, with scorpions as large as dogs and flying insects the size of seagulls. With Carboniferous Giants and Mass Extinction, palaeobiologist George McGhee, Jr. presents a scholarly but fascinating overview of the rise and fall of this lost world, and why it still matters to us.

Book review – Climate Change and the Health of Nations: Famines, Fevers, and the Fate of Populations

When a history book leaves you reeling, you know that it has done its job properly. Climate Change and the Health of Nations is a grand synthesis of environmental history, charting the fate of civilizations and the links between climatic changes and the health of people. It is also a book that almost wasn’t.

Book review – The Cradle of Humanity: How the Changing Landscape of Africa Made Us So Smart

The story of human evolution is constantly being refined with new findings and there is a glut of accessible books that cover this topic from various angles. Yet, with The Cradle of Humanity, geography professor Mark Maslin manages to provide an interesting and novel take on the subject, showing the reader how a happy combination of larger factors conspired to influence and steer our evolutionary trajectory. It could have ended up so differently…

Book review – The Oceans: A Deep History

So, stop me if you’ve heard this one before, but it is often said that we know more about the moon than we do about our own oceans. However, palaeo-oceanographer and climate scientist Eelco J. Rohling points out we know more than you might think. His new book, The Oceans: A Deep History, takes the reader through a 4.4-billion-year history of Earth’s oceans. Much more than just a book about water, this is foremost a book about the intimate link between our planet’s climate and its oceans, as they are far more intertwined than you might give them credit for.
