Book review – Lost Anatomies: The Evolution of the Human Form

Are science and art strange bedfellows? The answer to this tricky question will hinge on your definition of art. Science and illustration certainly are not. American palaeoartist John Gurche has spent three decades studying ape and human anatomy and making reconstructions of early humans. Amidst all this professional work, he has been quietly building a private portfolio of more artistic images as a creative outlet. After 27 years, this body of work is gathered here in Lost Anatomies. It is an exceptional and beautiful collection of palaeoart that occasionally ventures into slightly psychedelic territory, without ever losing sight of the underlying science.

Book review – Ancestors in Our Genome: The New Science of Human Evolution

After I read and reviewed Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past, I thought I knew about the changes to the story of human evolution based on studies of DNA. And given that Ancestors in Our Genome was published a few years before that book, I was curious what it could add to what I had been reading so far. As it turns out, a lot. As with my previous review, I should preface this one with the same warning that things are about to get complicated…

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”?

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 Edge of Memory: Ancient Stories, Oral Tradition and the Post-Glacial World

When I read the brief for The Edge of Memory, my first thought was: “Really, Bloomsbury is publishing a book on flood geology?” This creationist take on geology tries to interpret geological features in accordance with the Biblical account of a worldwide flood described in Genesis. If you haven’t read your Bible verses today, don’t worry, if I say “Noah” and “ark”, you probably know which one I mean. My guess was close, but not quite on the ball. Patrick Nunn, a professor of Oceanic Geoscience, here argues that ancient stories and myths hold within them descriptions of geological catastrophes and climatic changes. Welcome to the obscure academic discipline of geomythology.

Book review – The Curious Life of Krill: A Conservation Story from the Bottom of the World

Krill is one of those enigmatic invertebrate groups that feeds whole ocean ecosystems but remains itself little known. Even to a biologist such as myself (who has studied fish for crying out loud!), these critters are largely a set of question marks. I mean they are crustaceans, swim in the sea, are numerous and… oh look, a blue whale!

Book review – Dinner with Darwin: Food, Drink, and Evolution

Who could refuse such an invitation to dinner? In fourteen short chapters, Dinner with Darwin provides a smörgåsbord of topics on the role of food in human evolution and vice versa, many of which have been covered here in recent reviews. This is Jonathan Silvertown’s fourth book with the University of Chicago Press, and based on this, I would love to read his other books as well. Care to join me at the table?

Book review – Land Bridges: Ancient Environments, Plant Migrations, and New World Connections

Before plate tectonics became an accepted idea in geology, Lyell’s doctrine of uniformitarianism still ruled supreme (see my review of Cataclysms: A New Geology for the Twenty-First Century for a short introduction). A corollary was that the continents supposedly had always been where they are now. One observation scholars had to explain away was that the same fossils occur on both sides of the various oceans. Looking at maps, some people noticed the thin strip of land connecting North and South America and concluded that land bridges must have formed and sunk beneath the waves at just the right times in history to enable migrations (see Four Revolutions in the Earth Sciences: From Heresy to Truth for more details). As explained in The Tectonic Plates are Moving!, we know better nowadays. Nevertheless, the concept of land bridges is still alive and well today, and palaeobotanist Alan Graham here introduces five of them, exploring their effects on biogeography, climate, and human history.

Book review – Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past

You may have missed it, but archaeology is undergoing a silent revolution. The story of our deep history used to be based on skeletal remains, linguistics, and the analysis of objects and tools our ancestors left behind, but since about three years archaeologists have a new tool in their arsenal. The analysis of DNA from old bones, or ancient DNA. David Reich has been at the forefront of developing this technique and argues that it is rewriting most of what we thought we knew about the last 350,000 years or so of human history. Brace yourself, things are about to get complicated…
