Sundaland and Doggerland: The History and Mysteries of the Sunken Landmasses in Asia and Europe

By the time the Pleistocene Epoch ended around 12,000 years ago, Homo sapiens had become one of the most significant species on the planet. It was also near the end of that period of time that modern humans began to gradually populate what would become Europe, Asia, and the Americas, eventually becoming the inheritors of the Paleolithic era and the only human species to make it into the Neolithic era. The cold Pleistocene temperatures lowered water levels across the planet, exposing land that was not there before or after the period. At the same time, significant regions of the planet were very different during the Pleistocene, including Southeast Asia, particularly the modern islands of Bali, Borneo, Sumatra, and the Malay Peninsula, roughly equivalent to parts of Indonesia, Malaysia, and Thailand. This region, which modern scholars refer to as Sunda or Sundaland, was unique because all of it was connected by land, meaning today's islands were once part of a contiguous subcontinent, and in terms of the people, flora, and fauna, it was very different than it is today.
Among the most significant water displacement phenomena in the Western world was Doggerland on the northern European continent. The notable inundation occurred in both a steady and eruptive fashion covering a vast stretch of former tundra, a land bridge between today's British Isles and the European continent. The event brought about the modern English Channel and an expanded North Sea, and unlike the early supercontinents, the inundation of Doggerland took place after the appearance of people. Incrementally submerged since roughly 18,000 years ago as the climate warmed, the patch of sea between Britain and Europe is the subject of much recent scientific scrutiny.
