About this title

Synopsis

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.

Review

For centuries, biological scientists have been using the Linnean system of classification, organizing hierarchies of life forms by their perceived similarities and differences. In the late 20th century, some scientists have taken to using an alternative system called cladistics, which bases taxonomic classifications on ecological relationships. Under the first system, all algae fall into a single large category, which is then subdivided into various genera and species; under the second, green algae are grouped with plants, chromophyte algae with waterborne fungi, and so forth to account for the environments in which they live. Under the first system, dogs and wolves and coyotes are separated; under the second, they are united, for, the thinking goes, similarities of behavior and provenance are more important than mere lines of evolutionary descent, which can only be guessed at.

The debate over cladistics has largely been confined to seminar rooms and laboratories. Henry Gee brings it to the general public in this spirited look at how the science of paleontology, that grand tour of what Gee calls Deep Time, is conducted. Replacing old family trees with "cladograms," Gee challenges long-accepted notions about the past (for example, the classification of Archaeopteryx, which walks like a duck and quacks like a duck but is accounted for as a dinosaur) and argues for a return to rigor in testing hypotheses. His book, although about difficult issues, is immediately accessible, and readers seeking to learn something about cladistics--which Gee believes is "a revolution in thought as profound as that of Darwinian evolution by natural selection"--are off to a fine start in these pages. --Gregory McNamee
