Three different methods of character coding provide treesthat show: (a) presenceof four groups,viz., Balto-Slavonic clade, Romano-Germano-Celtic clade, Armenian-Greek group,and Indo-Iraniangroup (the two last groups possibly paraphyletic), (b) unstable position of the Albanian language,(c) unstablepatternof the basalmost IE differentiation, but (d) probable existence of the Balto-Slavonic-Indo-Iranian(''satem'') and the Romano-GeÍnano- Celtic ( + Albanian?) superclades.The results are compared with the phenetic approach to lexicostatistical data, whose results are significantly less informative concerning the basal pattern.The results suggest a predominantly branching pattern of the basic vocabulary phylogeny and little borrowing of individual words. Different scenarios of IE differentiation based on archaeolosical and geneticinformation are discussed.
