 Ereshefsky and Reydon (2015) have argued that this has led to a fundamental mismatch between scientific kinds and natural kinds. In the homeostatic property cluster view of kinds, the overarching principles of similarity and homeostatic mechanisms lead to many examples of scientific kinds which do not then count as natural kinds. For example, according to Ereshefsky and Reydon (2015), non-causal, functional and heterostatic kinds would not count as natural kinds despite the fact that many successful scientific kinds are non-causal, functional or heterostatic.
