The Black Death was the single greatest mortality event in recorded history, killing up to 50% of the European population in less than five years. New research from the University of Chicago, McMaster University, and the Institut Pasteur has found evidence that one of the darkest periods in recorded human history placed a significant selective pressure on the human population, changing the frequency of certain immune-related genetic variants and affecting our susceptibility to disease today. The results were published on October 19 in Nature.
