Glottochronology estimates how long ago languages diverged from a common ancestor. 🗣️ It uses statistical methods to analyze changes in vocabulary over time. The core idea is that languages change at a relatively constant rate. Glottochronology is controversial, as language change isn't always predictable. It's like trying to determine how far apart two trees were planted by measuring their growth rings. Some linguists view it skeptically, while others find it useful for broad estimations. It provides insight into human migration and historical connections between cultures.
