The Nostratic Hypothesis is a controversial linguistic theory suggesting that several language families, including Indo-European, Uralic, and Altaic, share a common ancestral language. This hypothesis proposes that these diverse languages can be traced back to a single Proto-Nostratic language, which is thought to have existed around 15,000 years ago. By exploring these connections, researchers aim to uncover the deeper relationships between seemingly unrelated languages and understand the origins of human language itself.
