Lemuria

Lemuria is the name of a proposed lost continent, held to have been situated in either the Indian or Pacific Ocean, formerly referenced as a hypothetical land bridge to explain fossil records during the mid-nineteenth century, and appropriated by the Theosophical Society and other orders in later years as a bygone home to a "root-race" of ancestors to modern humans.
