A New Way of Classifying Life?
... Recently, Carl Woese has challenged the assertion that there was just one primordial form. He says there were many life forms existing as a community, none of which were like what we call "cells" today. Eubacteria, Archaea, and Eukaryotes are very different in how they replicate, or make copies of t ...
