Background: Concerted 演化 is normally used to describe parallel changes at different sites in a 基因組, but it is also observed in 語言s where a specific phoneme changes to the same other phoneme in many words in the lexicon-a phenomenon known as regular sound change. We develop a general 統計 model that can detect concerted changes in aligned sequence data and apply it to study regular sound changes in the Turkic 語言 family. Results: Linguistic 演化, unlike the 遺傳 substitutional process, is dominated by events of concerted 演化ary change. Our model identified more than 70 historical events of regular sound change that occurred throughout the 演化 of the Turkic 語言 family, while simultaneously inferring a dated 系統發育 tree. Including regular sound changes yielded an approximately 4-fold improvement in the c
