As the sea rolled in, there would be mass migration from the sinking Sundaland Continent. It was likely triggered by an unknown mega catastrophe, which according to scientific detected observation data, "led to a sharp decline of the world population, emergence of many civilizations and the people memories (legends, myths, tales) around the world, such as that of Atlantis. The dispersal is also detected by the genetic studies." This was one of the most well-known examples of such abrupt change.1
Interestingly, the scenarios supports the claimed link between Sundaland and Plato’s Atlantis. The ancient Greek philosopher, describes Atlantis as a powerful and advanced kingdom that sank beneath the sea around 12,000 years ago. The time frame and size of the sunken Continent of Sundaland meets Plato’s description of Atlantis. Along with its topography, climate, flora and fauna together with aspects of local mythologies, all permit a convincing case to be made to support this idea.2
However, all we know is that climate change occurred and it marked the end of the Ice Age, and the accompanying rise in sea level would cause the Continent of Sundaland to sink below the Java Sea. Within this general time frame, the charts below depict the frequency and diversity in the population settlement history of the islands of Southeast Asia that were left behind when Sundaland sank below the sea.
I have yet another ancestray sub lineage to investigate O2a2b2a1a (Genetic Marker F1903). Doing so, I will consider several theories as to the destinations of my genetic ancestors beyond the immediate Southeast Asia.
For example, Historical Archaeologist, James Edward Sved suggests my Southeast Asian genetic ancestors may have island-hopped their way to South America sometime with the Ice Age glaciers meltdown and Pole shift. He explains, "Currently, Earth's poles wobble between approximately 22 and 24 degrees. When you consider the location of the North American glacier prior to the melting 20,000-12,000 years ago, it seems likely that the "North Pole" used to be almost 10 degrees closer to Canada. What would this do to Antarctica? It would put it more in the temperate locale of, say, New Zealand - not entirely and perpetually frozen, and not covered with Ice.
In my scenario, with sea levels considerably lower than they are today (120 Meters), the
aforementioned ancients could have paddled from island to island (There were many more
islands above-water then), walked across a section of Antarctica, and right onto South
As for that Most Recent Common Ancestor who is mentioned throughout these
pages, here is the take of Gordon Chang, a senior Yale scientist. "the most recent common
ancestor would have lived less than 1,000 years ago. He also introduced the "identical
ancestors point," the most recent time -- less than 2,000 years ago In the vein of full
disclosure, consideration should be given to the work of MIT scientists, Chang, Rohde,
and Olson who assert the most recent common ancestor of mankind lived as recently as about
3,000 years ago, and the identical ancestors point was as recent as several thousand years
ago. "No matter the languages we speak or the color of our skin, we share ancestors who
planted rice on the banks of the Yangtze, who first domesticated horses on the steppes of
the Ukraine, who hunted giant sloths in the forests of North and South America, and who
labored to build the Great Pyramid of Khufu." click

's more conservative IAP-- then 4 billion more people back to 10,000 BC. Using this model, a first estimate,
the queen has about 6 billion ancestors since the domestication of wheat, a bit less than the current population of
Earth, plus billions more in the Paleolithic past. a more complete answer than this requires a definition for the
beginning of humanity or a decision to count pre-human ancestors, not only Neanderthals and Denisovans,
Nature Science Update reported on a surprising find by Joseph Change (Yale) and Douglas Rohde (MIT).
They claim, based on computer modeling of human breeding and migration, that we are all related to
the same common ancestor, not millions, but just thousands of years ago, possibly just 1500 BC in
Asia, and that perhaps a couple of thousand years before that, everyone alive at that time was an
ancestor of all of us living today. The results are published in Nature Sept. 30.1

Jotun Hein (Oxford) cautions in the same issue2 that genealogical questions are “distinct from
questions about the history of our genetic material,” which are estimated by different methods:
“Universal common ancestry (in the pedigree sense) and genetic common ancestry thus occur on
different timescales,” he says. 2Jotun Hein, “Human evolution: Pedigrees for all humanity,”
