요약	Computational phylogenetic linguistics borrows the statistical machinery developed in evolutionary biology — Bayesian inference, maximum likelihood, and distance-based network methods — and applies it to coded linguistic data, chiefly cognate-judged basic vocabulary, to infer language family trees and estimate when branches diverged. By treating linguistic characters like the molecular characters in a gene alignment and modelling their change probabilistically along a tree, the approach produces classifications with explicit measures of uncertainty and, when calibrated, dated phylogenies. Its best-known applications are the Gray and Atkinson and Bouckaert et al. analyses of Indo-European origins.	The Comparative Method is a foundational technique in historical linguistics for reconstructing ancestral languages and establishing genetic relationships between related languages. Pioneered by Sir William Jones in 1786, it systematically compares phonological, morphological, and lexical features across languages to identify regular sound correspondences and trace their shared origins. This method underpins modern historical linguistics and has been essential for understanding language families worldwide.
