Lemuria
The lost continent of Lemuria was first hypothesized during the 1860s to explain the geographic distribution of lemurs, which are found on the island of Madagascar off the eastern coast of Africa and in Southeast Asia but not in any of the lands in between. Scientists hypothesized that a land mass must have connected Africa to the Indian subcontinent some 250 to 65 million years ago; some suggested that it stretched all the way to Australia.[1] This theory fell out of favor in the scientific community as lemur-like fossils were discovered in other parts of the world and plate techtonics became better understood[2], but enthusiasm among the general public has long outlived scientific interest. Today, Lemuria figures prominently in the lore of Tamil nationalism in southern India as a lost homeland.[3]
