    • Genome-Wide Scans Provide Evidence for Positive Selection of Genes Implicated in Lassa Fever 

      Andersen, Kristian G; Shylakhter, Ilya; Tabrizi, Shervin; Grossman, Sharon Rachel; Happi, Christian Tientcha; Sabeti, Pardis Christine (The Royal Society, 2012)
      Rapidly evolving viruses and other pathogens can have an immense impact on human evolution as natural selection acts to increase the prevalence of genetic variants providing resistance to disease. With the emergence of ...
