In Search of Deep Time: Beyond the Fossil Record to a New History of Life

A revolutionary approach to biology and evolution uses DNA research and the study of cladistics to compare fossilized remains and model the most likely common ancestor of many dinosaur species.

Cladistics--the science of comparison--is transforming the way paleontologists view evolution.

In Search of Deep Time strips away conventional assumptions about the evolution of life to reveal a world that may be far stranger and more humbling than had been previously imagined. The concept of deep time was first used by John McPhee to describe intervals of time incomprehensibly greater than our daily experience.

Henry Gee explains the rise of cladistics as the best technique for making sense of the organic changes that unfold within deep time.
