Metamorphosis

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.
