Reading the entrails of chickens: molecular timescales of evolution and the illusion of precision.

Trends in genetics : TIG - 1 Feb 2004

Graur Dan, Martin William

Abstract excerpt

For almost a decade now, a team of molecular evolutionists has produced a plethora of seemingly precise molecular clock estimates for divergence events ranging from the speciation of cats and dogs to lineage separations that might have occurred approximately 4 billion years ago. Because the appearance of accuracy has an irresistible allure, non-specialists frequently treat these estimates as factual. In this...
