[ABO blood-group system in the fossil remains at the mesolithic cemetary in Vlasac (6,300-5,400 B.C.)].

By the several generally accepted methods, the authors tested the ABO blood group system of human fossil remains of the mezolit cementery of Vlasac (lower flow of the River Danube). The results of these examinations showed a biological similarity of the population in all of the three cementery layers and a difference in blood groups in these people and the present inhabitants of that region. These examinations are of great interest for the study of the structure of the prehistorical population and its migrations.
