Discrete cranial traits of 6,426 skulls from Lithuania Medical Genetics, and adjacent territories as well as 3,734 skulls belonging to the Neolithic, Bronze Faculty of Medicine, Age, 2,000 YBP and 1,000 YBP were investigated. We disposed of data on the Vilnius University, ethnic odontology of 4,993 modern Lithuanians as well as of 1446 skulls dated Vilnius, Lithuania to 2,000 YBP and 1,000 YBP. Results. Two separate clusters consisting conse- quently of four Baltic and two Finnish groups emerged in the dendrogram (Fig. 1). The mesocranial Mesolithic population in Lithuania might be related to the Middle-European kernel of mesocranes. The Middle-European orientation of the Neolithic and Bronze Age Lithuanian population is evident. The influx from the eastern part of the ancient Baltic area was detected in the 2,000 YBP po- pulation. The Lithuanian 1,000 YBP population was more homogeneous than the inhabitants of Latvia (Fig. 2). The Y chromosome haplogroups 1 and 9 show complementary clines from southeast to northwest of Europe, the Baltic peoples (Latvians and Lithuanians) demonstrating a mixture of western and eastern ge- netic traits (Fig. 3). In Northern Europe, strong geographical, linguistic and cultural barriers can be identified. Three main migration directions could have a real influence on the formation of the Lithuanian gene pool. Conclusions. Anthropological, archaeological and linguistic data demonstrate that there was no common ancestry of the Balts and the Finns. Genetic and phenetical simila- rities might occur due to gene exchange between adjacent populations on the northern and eastern borderlines of the ancient Baltic area that took place from the Mesolithic time. It is impossible to date the emergence of some genetic and anthropological similarities between the Balts and the Finns.
