The Paleontologist Who Rewrote Evolution

Stephen Jay Gould famously challenged the idea that evolution is a slow, steady march. He proposed that species often remain unchanged for eons before suddenly evolving during brief, rapid bursts.

This theory, known as punctuated equilibrium, changed how we view the fossil record forever. Instead of seeing gaps in fossils as mistakes, Gould argued they were evidence of these quick evolutionary jumps. He was a master at turning complex science into fascinating stories for the general public. His work continues to influence how we understand the history of life on our planet today.
