Case Study 6:
Evolving language in the lab

evolving languages


Where does language come from? Some scientists have answered this question by focusing on how our brains evolved to learn languages. We have studied the other side of the coin - how languages themselves evolve to become better adapted to being learned by us. To do this we allowed miniature languages to evolve in the lab.

By exposing each volunteer in our experiments to the language produced by the previous volunteer, we saw how language adapts to fit our brains. Over time our miniature languages become easier to learn, and started to show the basic "design-features" we see in real languages. Cultural evolution may be as important as biological evolution in explaining the origins of humanity's defining characteristic: language.
