It is conjectured that the first humans migrated into Europe in several waves, either from Asia Minor across the Bosporus and into the Balkan region, or from Asia by way of the steppes. River barriers, mountains, and forested lands help to divide early Europeans into distinct groups, and by about 4000 B.C. humans were well-established. | It is conjectured that the first humans migrated into Europe in several waves, either from Asia Minor across the Bosporus and into the Balkan region, or from Asia by way of the steppes.
