 Griffiths and Matthewson (2018) attempt to rehabilitate an evolutionary account of function in this context. They tie a selected effects interpretation of function to life history theory, with the advertised aim of providing an explication of pathology that grounds it in a mature science rather than trying to recover some commonsense, or even medically prevalent, concept of disease. Their key contention is that this gives them a scientifically sound way to make discrimination that would otherwise be puzzling, such as the distinction between disease states and senescence, and the means to sort populations into principled reference classes. The resulting picture (Matthewson and Griffiths 2017) is one which generates a variety of evolution-based ways in which organisms can "go wrong". This sets up a taxonomy of opportunities for intervention: some organisms are malfunctioning; others are working properly but in the wrong environment; others are badly off because the environment is inhospitable even though it is normal for them and they are working as they have evolved to; still others generate a development pathway based on misleading information about what optimal development will require. This way of setting up the issues is strongly revisionist, and arguably is no longer an attempt to define disease at all as most of the scholars we have discussed would understand it. Matthewson and Griffiths argue for the congruence of this account with our best science and its stress on the continuity of human and non-human biology.
