What is it about?
Does the history of our languages match the history of our genes? Charles Darwin thought yes, others said no. More than 7000 languages are spoken in the world. This linguistic diversity is transmitted from one generation to the other, as we learn the language of our parents. The transmission of languages can be compared to the transmission of biological traits and genes, suggesting similar evolutionary paths. But languages can be learned not only from the parents, but also from other groups and peers. Are languages and genes tied together in human history? With a global database linking linguistic and genetic data we found a large number of matches but also widespread and systematic mismatches, in around 20% of the cases.

Why is it important?
The identification of mismatches is key to understanding human evolution. Genetics can help to reconstruct human demography and trajectories, which can be confronted with the evolution of other cultural traits.
