Summary

Story summary

A study in *Science Advances* examines how human genetics influences language changes from population contact.
Researchers analyzed genetic data from over 4,700 individuals across 558 populations, finding languages become 4-9% more similar with group mixing.
The study suggests social dynamics impact language evolution more than structural features.
Contact can lead to both convergence and divergence, reflecting the complexity of language evolution.
