01A new study measured the genetic diversity of neighbouring languages to understand how human languages became more varied before large migrations and population movements reshaped much of the world.
02The researchers created a global database linking linguistic and genetic data, entitled GeLaTo (Genes and Languages Together), which contains genetic information from some 4,000 individuals speaking 295 languages and representing 397 genetic populations.
03Linguistic hotspots may offer glimpses into how human languages became more varied before large migrations and population movements reshaped much of the world.
04The study suggests that linguistic diversity is linked to genetic diversity, with neighbouring languages showing distinct genetic profiles.
05Genetic history can reveal why some languages are so unique by identifying patterns of language contact and migration.
06A new perspective on Indian linguistic and cultural connections to the wider world has been offered by DNA studies revealing how Indian languages evolved.

Trap alerts

Most people think that language and genetics are unrelated, but actually they have a significant relationship in understanding linguistic diversity.
Most people think that genetic data is only relevant for medical purposes, but actually it can also be used to study human migration patterns and language evolution.
