Kopsavilkums	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 the foundational technique of historical linguistics for demonstrating that languages are genetically related and for reconstructing their unattested common ancestor. By systematically comparing cognate words across related languages and uncovering the regular, recurring sound correspondences between them — exemplified by Grimm's Law in Germanic — analysts reconstruct the forms of the proto-language and the sound changes that produced each daughter, and on that basis build the family tree. It is a qualitative, evidence-driven method distinct from the generic logic of cross-case comparison: here the 'comparison' is of linguistic forms governed by the regularity of sound change.
