The word biology derives from the Greek words bíos (βίος in Greek), meaning “life”, and -logía (-λογία in Greek), meaning “branch of study”, and is usually defined as “the study of life”. But what is life? Remarkably, biologists cannot agree on a definition. Everyone can name clear examples of living and non-living things. However, as so often in biology, there is no sharp demarcation between the two. There is a grey area where things are, well, somewhat alive? Lifelike? It is these borderlands between life and non-life that famous science writer and journalist Carl Zimmer explores in Life’s Edge. Instead of providing an answer, this intellectually stimulating and rewarding book will help you understand why it is such a hard question to begin with.
One objection sometimes raised against the search for extraterrestrial life is that our planet is rich with bizarre life forms that we still poorly understand. As a biologist, you are usually so close to the subject that you sometimes forget just how otherwordly our home planet can be. With his beautifully written book Entangled Life, biologist Merlin Sheldrake shook me out of that daze by offering a truly mind-opening book on fungi. Excitingly, he does so without floating off into speculative or esoteric territory.
Fungi have been eaten, worshipped, reviled, and studied for centuries. Neither animal nor plant (though originally classified as such), they occur pretty much everywhere, from the frigid icy wastes of Antarctica to between your toes. And yet I, like many others, know surprisingly little about them. With part of their life happening underground and on a microscopic scale, they easily evade our attention. With Fungipedia, mycologist Lawrence Millman provides a delightful little introduction to the world of fungi.
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.
