Superlative: The Biology of Extremes

Welcome to the biggest, fastest, deadliest science book you’ll ever read.

The world’s largest land mammal could help us end cancer. The fastest bird is showing us how to solve a century-old engineering mystery. The oldest tree is giving us insights into climate change. The loudest whale is offering clues about the impact of solar storms.

For a long time, scientists ignored superlative life forms as outliers. Increasingly, though, researchers are coming to see great value in studying plants and animals that exist on the outermost edges of the bell curve. As it turns out, there’s a lot of value in paying close attention to the oddballs nature has to offer.

Go for a swim with a ghost shark, the slowest-evolving creature known to humankind, which is teaching us new ways to think about immunity. Get to know the axolotl, which has the longest-known genome and may hold the secret to cellular regeneration.
