Metamorphosis has always been one of biology’s greatest wonders and toughest riddles. To emerge a butterfly, a caterpillar dissolves inside its chrysalis and builds a brand new brain, wings and legs. Why all this destruction and remodelling? Why all this wasted energy and time?

Oren Harman beautifully unfurls the untold story of metamorphosis across two millennia, asking why it has obsessed and inspired us so profoundly. Along the way we meet poets, artists, philosophers, and a cast of scientists as colourful as the animals themselves: whether Aristotle determining cucumbers had souls, Sigmund Freud searching in vain for eel testicles, or a Japanese zoologist singing karaoke to a baby jellyfish.

Taking us on an exhilarating journey through the creatures that metamorphose – a staggering three-quarters of all animal species – from starfish reproducing in reverse in ocean depths, to poison dart frogs on steaming rainforest canopies, to human adolescents struggling to control themselves, Metamorphosis is a new classic of natural history: a book that, by explaining a mystery of nature, causes us to relearn ourselves.

Reviews

Laura Redniss, author of Oak Flat
Metamorphosis is a soulful, genre-defying inquiry into the nature of transformation. Harman interweaves a history of scientific discovery with philosophy and memoir, introducing readers to astonishing characters and discoveries that bring us from the depths of the ocean to the furthest reaches of outer space. Metamorphosis asks difficult questions with great tenderness and deep humanity. It is a book full of wonder and revelation
Sean B. Carroll, author of THE SERENGETI RULES
A masterful tale of the long quest to understand one of the most wondrous and enigmatic phenomena in the animal world. Fueled by Oren Harman's boundless curiosity and rich storytelling, Metamorphosis roams the globe to meet fascinating creatures and equally colorful naturalists determined to penetrate their secrets. A thoroughly enjoyable and illuminating journey
Janet Browne, Harvard University, author of CHARLES DARWIN: A BIOGRAPHY
Inspired by history, language, and biology, Oren Harman explores a wonderland of animal lifecycles to tell a truly fascinating tale of transformations in body and identity. His story culminates in the growth of a human child and asks how is it possible to remain ourselves while changing all the time? A book to treasure
Lorraine Daston, author of OBJECTIVITY
Stranger than the strangest imaginings of ancient mythology or science fiction are the metamorphoses undergone by the most unprepossessing of organisms: the immortal medusa, the starfish that is simultaneously child and adult, the axolotl in which the parent is the child to its offspring. Oren Harman weaves together science, history, philosophy, and the musings of a parent-to-be in this beautiful book about the twists and turns in the plot of life
