This has been done before using H. pylori as a model, but it is remarkable nonetheless to see how innovative researchers are in using different models to track human migration patterns… this time with HSV 1 or human simplex virus 1.
For the study, which is published in the open access journal PLoS ONE, the researchers compared 31 strains of HSV-1 collected in Africa, Europe, Asia, and North America. They then mapped patterns of mutations using high-capacity sequencing and to reconstruct cladograms. They were able to support what anthropologists and molecular geneticists have already — that humans originated in Africa, spread out into Europe and Asia, and then ultimately crossed the Beringia “land bridge” into North America.
