Hypothesis
Genetic distance between human populations tends to be correlated with linguistic distance.
Note
When assessing the results of their model, the authors also evaluated a secondary hypothesis in passing, which was the idea that there is a consistent, widespread sex bias in the transmission of language. The model did not support this secondary hypothesis.
