A new paper in Proceedings of the Natural Academy of Sciences reports a phylogenetic tree of seven language families of Eurasia postulated to form a linguistic superfamily that evolved from a common ancestor around 15,000 years ago. Some frequently used words have been retained in related forms since the end of the last ice age. The proposed phylogenetic tree, in some sense, backs up our previous analysis (published seven years ago) of a different dataset using our proposed method based on consensus of low weight ultrametric trees (see Fig. 1.c of "Hierarchical Clustering, Languages and Cancer, in Applications of Evolutionary Computing Lecture Notes in Computer Science Volume 3907, 2006, pp 67-78).
