Prokaryotic Perspective

  • Arthur L. Koch


“Evolution” is a word that came into biology from the discipline of geology and the word suggests that mountain ranges will erupt, will be worn down, only to erupt again. Abiotic change, even it called “evolution,” is quiet distinct from biotic evolution. If a mountain “figured out a better way to live,” there would be no way for it to leave a legacy for later descendent mountains; it has no genetic system. Some aspects of abiotic evolution may be quick on the geological scale, like the development of random polymers after the precursors arise, but abiotic evolution can be slow and of long duration. For example, after the big bang, stars had to form and die and be reborn to cycle through several generations until one, like our own sun, could have a solar system with planets containing suitable elements and with a physical environment so that life forms could develop based on organic molecules. Thus, the progression of star types is an evolution in which a descendent stars has properties generated by nucleosynthesis of its predecessor, but again this is not “adaptive” as in the way Darwin used the term “evolution,”
