Is macroevolution reducible to microevolution? Hot news: philosophers of science like to argue about the reduction of one kind of science to another. Many have asked whether macroevolution reduces to microevolution. That is, whether or not larger changes in evolution are "just the sum of" small changes. We need to understand what "reduction" means in the philosophy of science before we can start accusing people of being "reductionists" or "holists ". From a philosophical perspective, one might say macroevolution is just a bunch of microevolution. It's also just a bunch of chemistry. And physics. These are unhelpful answers, so we might find it worthwhile to ask how scientific domains relate to each other. Whenever a scientist or philosopher asks if two theories are reducible one to the other, there are several answers that can be given. One is if the first theory being reduced A is adequately captured by the reducing theory B . Another is that A is not entirely captured by B . A third is that A and B each have overlapping areas, and areas only they capture. This is called the problem of theory reduction . Reduction has been a philosophical problem with respect to science for about 60 years. It comes in three main varieties: methodological reduction , which is the notion that one ought to try to explain wholes in terms of the parts and their interactions; ontological reduction , which is the notion that all the units or entities of one theory are composed of units or entities of another; and metaphysical reduction , which is the claim that only one kind of thing exists (also called "monism"). Ontological reduction includes reducing all the laws and dynamic generalisations of
