Europe Population

Although it is not precisely known when humans first lived in Europe, they probably migrated there from the east in several waves, mostly via a no longer extant land bridge from Asia Minor into the Balkans and by way of grasslands north of the Black Sea. Parts of Europe had a substantial human population by about 4000 bc. Geographical barriers such as forests, mountains, and swamps helped divide the peoples into groups that remained largely separate for long periods. Some intermixing of peoples occurred as a result of migrations, however.
