Darwin taught us that species evolve through variation and selection, yet he couldn’t see beneath the surface. He didn’t know the mechanics of heredity or how organisms acquire their forms during development. After Darwin’s time, biologists explored fossils and comparative anatomy, but the link betw...

From Endless Forms Most Beautiful: The New Science of Evo Devo and the Making of the Animal Kingdom

One of the most astonishing discoveries in modern biology is that all animals, from flies to humans, share a deep common heritage — a set of master control genes that orchestrate body plans. I call these genes the biological toolkit. Imagine a carpenter’s shop where every project, from carving a toy...

From Endless Forms Most Beautiful: The New Science of Evo Devo and the Making of the Animal Kingdom

Before Darwin sailed into history, there existed a tapestry of explorers and thinkers who began weaving the threads of biological understanding. The eighteenth century brimmed with naturalists like Alexander von Humboldt and Charles Lyell, whose meticulous observations of geography and geology began...

From Remarkable Creatures: Epic Adventures in the Search for the Origins of Species

Aboard the HMS Beagle, Charles Darwin embarked on a journey that forever changed how we see life. He was not merely cataloging species; he was confronting the evidence of nature’s restlessness. The trip’s five years exposed him to volcanic islands, coral reefs, pampas filled with fossils of giant ma...

From Remarkable Creatures: Epic Adventures in the Search for the Origins of Species

The story begins not on the African plains but in the quiet laboratories of mid-twentieth-century Paris. There, two young scientists, Jacques Monod and François Jacob, were seeking to understand how bacteria adapt to their environment. What they discovered transformed biology. By studying the bacter...

From The Serengeti Rules: The Quest to Discover How Life Works and Why It Matters

Once biologists discovered the logic of gene regulation, they began to uncover variations of this theme across the entire molecular landscape. Cells, it turned out, were filled with intricate feedback and feedforward systems, each fine-tuned to maintain homeostasis. Negative feedback ensured that wh...
