In a recent blog post (http://evmed.asu.edu/blog/evolutionary-medicine-top-ten-questions), Randy Nesse suggests that the presentations and discussions at the second annual conference of the International Society for Evolution, Medicine, and Public Health (ISEMPH) were
“… instigated 25 years ago as George Williams and I discussed and grappled with how evolution could be useful for medicine, and what to call the enterprise.”
In her chapter (Bentley, 2016) introducing the just published book, “Evolutionary Thinking in Medicine: from Research to Policy and Practice,” the author acknowledges activity that can be considered evolutionary medicine in the years prior to 1991 but confines it to before roughly 1940. Following the end of World War II, Professor Bentley finds little to no evidence of significant work in the field until the 1990s. Unfortunately, these claims disregard substantial numbers of evolution-related studies that either influenced fundamental understanding of human health and disease or affected medical practice.

Last month, Murphy and colleagues (Cell, 2015) published a fascinating report about a patient with an immunodeficiency syndrome that underwent spontaneous resolution. The mechanism for this remarkable outcome points to the importance of somatic cell selection and evolution in the origins, pathogenesis, and most dramatically in this case, elimination of disease.

Currently, I am on vacation near the beach in South Carolina. Consequently, I have opted for a topic that is bit different than the majority of my monthly commentaries in that it focuses not on a recent original report but instead on a conceptual point made in a book over thirty years ago. Nevertheless, after a somewhat less strictly scientific diversion I will come to the central idea at issue, which is arguably the premier exemplar of the relevance of evolutionary principles to the operation of the immune system on short time scales, by which I refer to the concept of clonal selection. But first, we make a foray into the world of magazine publishing and the niche within that domain focusing on the arguably more intellectual readers. (more…)
In his essay (2011) on the history of Darwinian (or evolutionary) medicine, Jonathan Fuller describes potentially relevant interests and insights that preceded the famous paper by Nesse and Williams (1991) that is widely regarded as having catalyzed the resurgence of interest in applying evolutionary concepts and principles to medicine. For example, the author describes aspects of Aristotle’s biological thinking as well as elements of the medical concepts of Hippocrates that anticipated some features of evolutionary medicine while possibly also impeding full acceptance of the evolutionary perspective on medical phenomena. Fuller also mentions the writings of individuals such as A. C. Allison and Paul Ewald relating to infectious disease as relevant examples of pre-1991 applications of evolutionary thinking to medically-relevant problems.
There is, however, another medical field with a relatively long history (going back at least a century) of applying evolutionary principles and concepts to understanding phenomena of interest, immunology (Silverstein, 2003), which Fuller mentions only in passing. (more…)
