“Riveting. … Pattison’s uncanny ability [is] to write evocatively about science. … In this, he is every bit as good as the best scientist writers.” —New York Times Book Review (Editors’ Choice)

“Brilliant. … A work of staggering depth.” —Minneapolis Star Tribune

A decade in the making, Fossil Men is a scientific detective story played out in anatomy and the natural history of the human body: the first full-length account of the discovery of a startlingly unpredicted human ancestor more than a million years older than Lucy

It is the ultimate mystery: where do we come from? In 1994, a team led by fossil-hunting legend Tim White uncovered a set of ancient bones in Ethiopia’s Afar region. Radiometric dating of nearby rocks indicated the resulting skeleton, classified as Ardipithecus ramidus—nicknamed “Ardi”—was an astounding 4.4 million years old, more than a million years older than the world-famous “Lucy.” The team spent the next 15 years studying the bones in strict secrecy, all while continuing to rack up landmark fossil discoveries in the field and becoming increasingly ensnared in bitter disputes with scientific peers and Ethiopian bureaucrats.
