    Would the process of speciation be considered a microscopic system?

    I think you need to define what you mean by a microscopic system before one can answer this.

    I can formulate replies that demonstrate it is exclusively a microscopic system, that it is never a microscopic system, that it is partially a microscopic system, and that it is sometimes a microscopic system, all depending upon the definition one chooses.

    the 2nd Law of Thermodynamics applies only to macroscopic systems. What Wikipedia's or whoever's definition of macroscopic system is i don't know. I'm just trying to figure out if the 2nd law of thermodynamics applies to speciation. But like you said, Ophiolite, it all depends on the way you're looking at it... It seems that one could say speciation is microscopic because ultimately the changes that occur in the organisms is at the molecular level, but if you're looking at the biodiversity of an area or something, then change is occuring at a macroscopic level... I hope that makes at least a little sense...

    I have not seen it stated, impicitly or explicitly, that the second law applies only to macroscopic systems. It applies to closed systems, but I see no reason that a microscopic system cannot also be a closed one, anymore than a macroscopic one cannot be open.

    The points you make concerning the micro/macro character of evolution were what I had in mind.
