Book review – When the Sahara Was Green: How Our Greatest Desert Came to Be

7-minute read

When seeing the world through a deep-time lens, no landscape feature is permanent. The Sahara, for example, “only” came into existence some 7 million years ago. In that time, it has not always been the parched desert it is now but has been green and verdant numerous times, crisscrossed by rivers and home to hippos, turtles, fish and other animals and plants typical of wetter climes. In this book, retired earth scientist Martin Williams draws on a long lifetime of research and desert expeditions to give a very accessible introduction to the surprisingly complex geography of the Sahara, answering some very basic questions.

Book review – Tropical Arctic: Lost Plants, Future Climates, and the Discovery of Ancient Greenland

7-minute read

Greenland’s name might be considered one of history’s great ironies, apparently part of a cunning plan to attract Viking settlers. The locals simply called it Kalaallit Nunaat or “land of the Kalaallit”, after their people. However, once upon a time, Greenland was green. Tropical Arctic is the fruit of an 18-year collaboration between two palaeobotanists and an artist to bring to life the plant fossils found in East Greenland. In three paintings, it provides a glimpse of Greenland during a 10-million-year window at the Triassic–Jurassic boundary, some 200 million years ago. Much more than a coffee table book, it details the research that goes into producing scientifically accurate artwork, making it a rare treat for readers interested in botany and palaeontology.

Book review – The Sloth Lemur’s Song: Madagascar from the Deep Past to the Uncertain Present

7-minute read

Before reading this book, I admit that my knowledge of Madagascar was shamefully rudimentary: I knew its location on the world map, the name of its capital city, and that lemurs are part of its endemic fauna. Fortunately for me, anthropologist Alison Richard, backed by her five decades of research experience, has written a natural history book in the broadest sense of the word, encompassing geology, (palaeo)climatology, botany, zoology, conservation, and much else besides. She skillfully dismantles simplistic dichotomies and is particularly passionate about challenging the dominant conservation narrative that Madagascar was a forested paradise until humans arrived. The Sloth Lemur’s Song is revelatory in more than one way and I came away with a much deeper understanding of this remarkable island.

Book review – Mammalian Paleoecology: Using the Past to Study the Present

7-minute read

Scottish geologist Charles Lyell quipped that the present is the key to the past. To say that the reverse also holds is more than just circular reasoning. Felisa Smith, a professor in ecology and evolutionary biology, studies extinct mammals and applies this knowledge to the present. This book is a neatly crafted package that gives the reader all the required background knowledge, while its case studies make for fascinating reading. (Spoiler alert: packrat middens are my new favourite discovery.)

Book review – Traces: The Memoir of a Forensic Scientist and Criminal Investigator

This book was originally announced with the subtitle Every Body Leaves a Mark. Next to a clever play on words, it also nicely captures the subject. Patricia Wiltshire is a professor in forensic ecology, botany, and palynology. That last discipline is the study of pollen and spores and is widely used in archaeology, for example for radiocarbon dating. Wiltshire used to be an environmental archaeologist before stumbling into a new career in her fifties when a phone call heralded an unexpected career change. Traces tells that story and is a fascinating first-hand account of her pioneering contributions to forensic science.
