When did Europe and Asia separate?

Anaximander placed the boundary between Asia and Europe along the Phasis River the modern Rioni in Georgia in the Caucasus Mountains from Rioni mouth in Poti on the Black Sea coast, through the Surami Pass and along the Kura River to the Caspian Sea, a convention still followed by Herodotus in the 5th century BC.

For most geographers today, the dividing line between Europe and Asia runs down the eastern edge of the Ural Mountains (in Russia), then along the Emba River (in Kazakhstan) to the shore of the Caspian Sea.
