This paper presents Axel Kristinsson, (Reykjavik Academy, Island) new hypothesis on the Indo-European expansion from the Cucuteni Trypolie location, and its importance for the Romanian research. His background on studies of massive movement of populations from the history of Europe such as the Celtic, Germanic, Slavic, or of the Vikings migrations from the history of Europe, not to mention the populating of the Americas, may offer a better solution for solving the IE spread. Kristinsson offers two models of expansion, by colonizing, and by ‘expansion system’, models that could be applied and observed in relation to the colonization of Dacia. Even though Kristinsson considers that the comparative mythology should not be regarded as a valid source in the IE discussions, one should not ignore the few patterns that could be observed in most of the IE cultures. An interesting example is presented to sustain this argument.
