Recently I came across an article The Lost Continent of Kumari Kandam in which I found this map:
I had never heard about Kumari Kandam and had to check Wikipedia: Kumari Kandam, “a mythical continent, believed to be lost with an ancient Tamil civilization” The Wikipedia article is interesting and worth reading.
Kumari Kandam never existed. The concept of a lost continent with a Tamil civilisation is the result of Tamil Nationalism . As I want to avoid this sensitive topic, I will give in this blog only some background information, starting with Lemuria.
In 1864 the English zoologist Philip Sclater explained the presence of lemur fossils in Madagascar and India, but not in Africa and Arabia by assuming that in the past Madagascar and India were connected by a landmass , which later was submerged by the ocean., He named this lost continent Lemuria.
A couple of years later this idea of a lost continent was picked up by the German scientist Ernst Haeckel, a staunch defender of Darwinian evolution. He suggested that this lost continent could have been the cradle of human evolution. Here is a map drawn by Haeckel.
Here is a detail. Notice the alternate name Paradise for Lemuria!
The “Out of Asia”” theory of human evolution was quite popular in those days.
We know now that Lemuria never existed and have a much more fascinating explanation: continental drift. I will write a separate blog about this topic. Continents (tectonic plates) have not a fixed location ,but move slowly. Here is a video of the continental drift the last 100 million years. India was still connected to Madagascar, but moved north until it collided with Asia (the collision caused the Himalayas). Also notice how at the start of the video Australia is still connected to Antarctica.
The classical Tamil literature (Sangam) mentions the occurrence of flooding, resulting in the loss of land. At the end of the 19th century Tamil scholars and nationalists suggested that Lemuria was the center of Tamil civilisation and named it Kumari Kandam. After its submersion Tamils had to migrate to other parts of the world, bringing there civilisation and language.
The submersion is often explained by the rise in sea levels after the last Ice Age. More than 100 meter. In itself that makes sense, as you can see in the Google image below where I have roughly indicated a contour line 120 m below sea level. Considerable amounts of land were lost to the sea during the past ~ 20.000 years.
But not a continent.
