In a striking confirmation of evolutionary theory—and a clear rebuttal of several fundamental creationist claims—scientists have demonstrated a close correlation between population-level immunity and the evolution of influenza viruses to evade that immunity. The findings, reported in eLife, align perfectly with predictions made by evolutionary biology: as the immune landscape of a population shifts, so too does the genetic makeup of viruses in an ongoing evolutionary arms race.
Disappointingly for creationists hoping for signs that biomedical science is abandoning evolution in favour of supernatural explanations, there is no such evidence. Nowhere in the study is there a hint that scientists are retreating from evolutionary principles or embracing a non-falsifiable belief system involving mysterious, unexplained entities. On the contrary, the researchers are clear and unequivocal: their results reinforce the view that viral evolution is a dynamic, adaptive process shaped by natural selection in response to host immunity.
Even more troubling for proponents of Intelligent Design (ID) is the unavoidable implication that the viral mutations observed in this study constitute what William A. Dembski calls "complex specified information"—which he argues can only arise through the intervention of an intelligent designer. If one follows that line of reasoning, the logical (if deeply uncomfortable) conclusion is that this designer is actively modifying viruses to undermine the very immune systems it supposedly created to protect us. Such behaviour can hardly be described as intelligent and is incompatible with the benevolent deity so often associated with the Intelligent Design movement.
