“The story of humanity’s prehistoric expansion across the planet is recorded in our genes. And, apparently, the story of the spread of language is hidden in the sounds of our words. That’s the finding of a new study, which concludes that both people and languages spread out from an African homeland by a similar process—and that language may have been the cultural innovation that fueled our ancestors’ momentous migrations.”
Interesting technique and interesting findings.
