Book review – Life’s Edge: The Search for What It Means to Be Alive

7-minute read

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.

Book review – The Cheating Cell: How Evolution Helps Us Understand and Treat Cancer

7 -minute read

Fifty years ago, US President Richard Nixon declared a “war on cancer” when he signed the National Cancer Act. Despite fantastic progress on some fronts, overall it is clear that we are not winning this battle. Cancer remains one of the leading causes of human mortality. But what if the tired war-metaphor is getting it all wrong? Brimming with thought-provoking questions, The Cheating Cell looks at cancer through an evolutionary lens and forces the reader to radically reconsider cancer; not as a bug, but as a feature of life.

Book review – On the Origin of Evolution: Tracing ‘Darwin’s Dangerous Idea’ from Aristotle to DNA

8-minute read

History will forever associate Charles Darwin with the theory of evolution, but the idea was in the air. Had not Darwin published his famous book, someone else would have likely snatched the prize. Husband-and-wife duo John and Mary Gribbin here examine the wider milieu in which Darwin operated and the many thinkers who preceded him. Given their previous collaborations, the first two parts of On the Origin of Evolution read like a well-oiled machine, but the book falters when they turn their eyes to the legacy of Darwin’s ideas.

Book review – The Story of Evolution in 25 Discoveries: The Evidence and the People Who Found It

6-minute read

After three previous books in this format on fossils, rocks, and dinosaurs, geologist and palaeontologist Donald R. Prothero here tackles the story of evolution in 25 notable discoveries. More so than the previous trio, this book tries to be a servant to two masters, resulting in a mixed bag.

Book review – Dinosaurs Without Bones: Dinosaur Lives Revealed by Their Trace Fossils

6-minute read

Say “dinosaurs”, and most people imagine fossilised bones and spectacular museum displays. But body fossils are not the only remains we have with which to reconstruct dinosaur lives. Nor, and this might sound controversial, are they the most important. Or so argues palaeontologist, geologist, and ichnologist Anthony J. Martin. Ichnology is the study of animal traces, whether modern or fossilised. Most traces are ephemeral and disappear within hours or days, but occasionally some are buried and end up in the fossil record. With tongue firmly planted in cheek, and with more puns than you can shake a T. rex thigh bone at, Martin forays into the rich dinosaur trace fossil record: from footprints, burrows, and nests, to teeth marks and fossil faeces. For all the jokes, and despite having been published in 2014, he raises some really interesting points.

Book review – Locked in Time: Animal Behavior Unearthed in 50 Extraordinary Fossils

7-minute read

Fossils can tell us what animals living in the distant past looked like. Over the centuries, palaeontologists have made incredible strides in reconstructing extinct life forms, helped along by cumulative experience, technological advances, and a steadily increasing body of rare but truly exceptionally preserved fossils. But reconstructing their behaviour – surely that is all just speculative? In Locked in Time, palaeontologist and science communicator Dean R. Lomax, with the able help of palaeoartist Bob Nicholls, presents fifty of the most exceptional fossils that preserve evidence of past behaviour: from pregnant plesiosaurs to a pterosaur pierced by a predatory fish. I was eagerly awaiting this book from the moment it was announced, but I was still caught off-guard by some of the astonishing fossil discoveries featured here.

Book review – Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA

7-minute read

The history of life is punctuated by major transitions and inventions: fish that moved onto land, reptiles that turned into birds. But how did these happen? In Some Assembly Required, Professor of Organismal Biology and Anatomy Neil Shubin provides an up-to-date and utterly engrossing account of the latest thinking on the great transformations in evolution. And he has one clue for you: nothing ever begins when you think it does…

Book review – The Selfish Ape: Human Nature and Our Path to Extinction

6-minute read

Having just read Barash’s Through a Glass Brightly, it seemed logical to next read The Selfish Ape by biologist Nicholas P. Money. With the dustjacket calling the human being Homo narcissus, and the book “a refreshing response to common fantasies about the ascent of humanity“, these two clearly explore the same ideas, though one look at the cover suggests a darker tone. Money mostly takes the reader on a tour of human biology to show how we are little different from our fellow creatures, spicing up his writing with bleak observations. This one, my friend, sees through the glass darkly…

Book review – Hacking the Code of Life: How Gene Editing Will Rewrite Our Futures

Since being released on the world in 2012, the biotechnological tool CRISPR has been making headlines. Biologists used to rely on the relatively blunt tools of genetic modification, but this new tool is so precise and versatile that they now speak of gene editing instead. For people in a hurry, Nessa Carey here provides a primer on the powers and pitfalls of gene editing. Hacking the Code of Life is accessible to readers without much background in genetics, focusing more on the applications and the questions it raises than the nitty-gritty details of the tool itself.

Book review – Skeleton Keys: The Secret Life of Bone

From Skeletor to the Danse Macabre, from Army of Darkness to ossuaries and holy relics – despite being largely hidden in life, skeletons are some of the most recognizable structures that nature has produced. Science writer Brian Switek has written a sizzling little book with Skeleton Keys* that delves into both the biological and cultural significance of human bones, showing them to be more than just a powerful reminder of death and mortality.
