Book review – Weird Earth: Debunking Strange Ideas about Our Planet

7-minute read

Geologist and palaeontologist Donald R. Prothero is a busy man. Next to writing a steady stream of books on geology, fossils, and evolution, he is a noted sceptic. Previous books have addressed cryptozoology, UFOs and aliens, and science denial more generally. In Weird Earth, Prothero debunks conspiracy theories and pseudoscience relating to our planet, making for an entertaining slaying of geological fringe ideas. However, his aim is not merely to demean, but also to show readers what the actual evidence is and how we gather it. If the idea of a flat earth strikes you as unbelievable, buckle up, because it gets much weirder.

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 – Neanderthal Language: Demystifying the Linguistic Powers of our Extinct Cousins

7-minute read

Neanderthals have enjoyed quite the renaissance in the last decade or so, with research attributing skills and capacities to them once considered uniquely human. One of the most contested claims in this arena is language. Since (spoken) language does not fossilise, nor leave material traces in the archaeological record, the case for Neanderthal language relies on indirect evidence. In this book, linguist Rudolf Botha takes a hard-nosed look at why this matter is so controversial and offers a framework to properly tackle it.

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 Anthropocene as a Geological Time Unit: A Guide to the Scientific Evidence and Current Debate

7-minute read

Since it was coined in the year 2000 by Paul Crutzen and Eugene Stoermer, the term “Anthropocene” has taken the world by storm – pretty much in the same way as the phenomenon it describes. Humanity’s impact on the planet has become so all-encompassing that it warrants giving this period a new name. As a colloquial term that is all snazzy, but are we actually leaving a tangible trace in the rock record to signal a transition to a new period?

Book review – The Science of Roman History: Biology, Climate, and the Future of the Past

6-minute read

One look at the title and you might be forgiven for quoting John Cleese. But rather than asking what the Romans can do for us, this book asks what we can do for the Romans. Walter Scheidel, who is a professor of humanities as well as classics and history, and a fellow in human biology, brings together a diverse cast of scientists. Their aim? To discuss what relatively young bioscientific disciplines can add to our picture of life in Ancient Rome as revealed so far by the more mature disciplines of history and archaeology. Which disciplines might these be? Prepare yourself for several mouthfuls as this book covers palaeoclimatology, archaeobotany, zooarchaeology, palaeopathology, population genetics, and the study of ancient DNA.

Book review – Symphony in C: Carbon and the Evolution of (Almost) Everything

Many works of popular science claim to be histories of almost everything or everyone, but earth scientist Robert M. Hazen might actually be in the position to stake that claim. Whether you are talking stellar evolution, the origin of life, organic chemistry, synthetic materials, or hydrocarbon fuels – the multifaceted atom carbon is ubiquitous and pervasive. Symphony in C is a whirlwind tour through geology, biochemistry, and evolutionary biology that is an incredibly absorbing read, although in places it almost comes apart at the seams under the intensity of its enthusiasm.

Book review – End of the Megafauna: The Fate of the World’s Hugest, Fiercest, and Strangest Animals

Mammoths and sabertooth cats are but two icons of an assemblage of large animals, or megafauna, that disappeared between roughly 50,000 to 12,000 years ago. As with all mass extinctions, several explanations have been put forward, but one man and his idea take centre stage in these discussions: Paul S. Martin’s overkill hypothesis. In End of the Megafauna, palaeomammalogist Ross D.E. MacPhee carefully scrutinises this idea, weighs up the arguments for and against, and explains its enduring allure. To quote Huxley, is this another example of “the slaying of a beautiful hypothesis by an ugly fact”?
