Lemuria & Mu

Lemuria began as a legitimate but mistaken scientific conjecture. In 1864 the zoologist Philip Sclater proposed a sunken land bridge he named ‘Lemuria’ to explain why lemur fossils appeared in both India and Madagascar — a reasonable idea before plate tectonics provided the real explanation. Once tectonics was confirmed, the hypothetical continent was abandoned by science. A parallel idea, ‘Mu,’ was promoted by Augustus Le Plongeon and especially James Churchward in the early 20th century as a vanished Pacific motherland of civilization, with no evidentiary basis.

The occultist Helena Blavatsky and later Theosophists absorbed Lemuria into a mythology of ‘root races’ and ancient spiritual masters, and from there it entered New Age and the ancient-astronaut hypothesis lore. On Ancient Aliens and in related traditions, Lemuria and Mu are presented as lost advanced or extraterrestrial-linked civilizations, and a distinctively American strand holds that surviving Lemurians dwell inside Mount Shasta in northern California.

There is no geological or archaeological support for Lemuria or Mu. Plate tectonics shows no sunken continent in the Indian or Pacific Oceans, the biogeographic puzzle Sclater addressed is fully explained by drifting continents, and the Mount Shasta material is demonstrably modern folklore and fiction rather than ancient tradition. Lemuria is a textbook case of a superseded scientific idea being kept alive as mysticism and pseudo-history.
