Machines can now map global language families faster than human experts
What happened
A new automated method for mapping how languages are related turns out to be better than relying on human experts. This means researchers can now build global language family trees faster and without needing scarce specialists.
Why it matters
Understanding how languages evolved meant relying on a few highly specialized experts. They would painstakingly compare words across languages. This new method means researchers can now map the relationships between thousands of languages at once, opening up global-scale studies that were impossible before.
The signal
Watch for new research papers that use this automated method to map previously unstudied language families or create much larger global linguistic datasets.
