With the sea about 120 metres lower, the central Cyclades were one island, from Andros to Ios, and the islands off Turkey from Lesbos to Kos were joined to Asia. The plate had about half again as much land as today. Most of it was already dry when the timeline begins; the rising sea drowned it between 16,243 and 8,325 years ago.
