Hitchhiking Virus Confirms Saga of Ancient Human Migration

Oct. 21, 2013 " A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.

....

"The viral strains sort exactly as you would predict based on sequencing of human genomes. We found that all of the African isolates cluster together, all the virus from the Far East, Korea, Japan, China clustered together, all the viruses in Europe and America, with one exception, clustered together," he says.
"What we found follows exactly what the anthropologists have told us, and the molecular geneticists who have analyzed the human genome have told us, about where humans originated and how they spread across the planet," said Curtis Brandt.

........

The new analysis could even detect some intricacies of migration. Every HSV-1 sample from the United States except one matched the European strains, but one strain that was isolated in Texas looked Asian. "How did we get an Asian-related virus in Texas?" Kolb asks. Either the sample had come from someone who had travelled from the Far East, or it came from a native American whose ancestors had crossed the "land bridge" across the Bering Strait roughly 15,000 years ago.
"We found support for the land bridge hypothesis because the date of divergence from its most recent Asian ancestor was about 15,000 years ago. Brandt says. "The dates match, so we postulate that this was an Amerindian virus."

More evidence collaborating the main stream theory.

Rather successful expansion in 150,000 to 200,000 years wouldn't you say?
