Inscription. In 1969, Carl Woese began using molecular sequences of RNA to study the evolutionary history of life on Earth, eventually determining the first “tree of life.” This project led, in 1977, to the discovery of a third branch of life: the archaea microorganisms distinct from bacteria (which they resemble) and eukaryotes (plants and animals). The concepts and discoveries emanating from this work have transformed biology, particularly evolution, ecology and microbiology.

2. Introduction to the Archaea. Dr. Carl Woese and his colleagues at the University of Illinois were studying relationships among the prokaryotes using DNA sequences, and found that there were two distinctly different groups. Those "bacteria" that lived at high temperatures or produced methane clustered together as a group well away from the usual bacteria and the eukaryotes.
