摘要

How do bacteria evolve and speciate in natural environments? How does bacterial evolution relate to bacterial systematics? Exploring these answers is essential because bacteria profoundly impact life in general and, in particular, that of humans. Much insight into bacterial microevolution has come from theoretical and computational studies and from multigenerational laboratory systems ("Experimental Evolution"). These studies, however, do not take into account the diversity of modes of how bacteria can evolve under the complexity of the real world, i.e., nature. We argue, therefore, that for a comprehensive understanding of bacterial microevolution, it is essential to study natural populations. We underline our argument by introducing the Bacillus simplex model from "Evolution Canyon", Israel. This metapopulation splits into different evolutionary lineages that have adapted to the microclimatically different slopes of "Evolution Canyon". It was shown that temperature stress is a major environmental factor driving the B. simplex adaptation and speciation progress. Therefore, this model population has proven highly suitable to study bacterial microevolution in natural habitats. Finally, we discuss the B. simplex intrapopulation divergence of lineages in light of current controversies on bacterial species concepts and taxon identification.
