Genetic exchange and evolutionary divergence in prokaryotes
Trends Ecol Evol.
1994 May.
Abstract
Recent work shows that genetic exchange in prokaryotes is less frequent but more promiscuous than that in eukaryotes. As a result, genetic exchange plays very different roles in determining the patterns of evolutionary divergence in these major groups. Because sexual isolation is not a prerequisite for divergence in the prokaryotic world, the biological species concept is not appropriate for bacteria. However, there is a species concept that may apply universally.
