Scientists Reveal Surprising Black Death Genetics

Infectious diseases have exerted some of the most intense selective pressures in the evolution of humans and other animals.It's no surprise, then, that many cases of population-specific positive selection in humans involve immune-related genes, supporting the idea that exposure to new or recurring pathogens has driven adaptation.However, linking signatures of natural selection directly to the pathogens responsible is difficult unless the genetic markers involved still influence susceptibility to the same pathogen in modern populations.Understanding the forces that have shaped the human immune system is crucial for revealing how past diseases contribute to disease vulnerability today.In a study, scientists aimed to uncover signatures of natural selection in Europeans driven by Yersinia pestis, the bacterium responsible for the bubonic plague.
