The cataclysmic destruction of a race of Lemurian progenitors was lent further credence by recent genetic studies which indicated that sometime in the past there was an environmental catastrophe that greatly reduced the population and available gene pool, which produced a population bottleneck that significantly curtailed genetic variability. When the Sumatran, Mount Toba erupted 71,000 years ago, gigantic tidal waves swept over the oceans. It has also been speculated that asteroids that either passed dangerously close to the Earth or actually impacted the planet might have been the cause of the intense vulcanity, glacial meltdown, and the rise of the sea levels.

There are differing viewpoints about locations, timelines, what the people looked like, how they lived their lives, and what their spiritual beliefs were. Some say that Lemuria was located near India, while, most place it in the Pacific Ocean. Some say that the Lemurians predated the Atlanteans, while, others think they existed at around the same time or that their timelines overlapped during critical timeframes. Some say that the Lemurians were artistically and spiritually inclined, while, the Atlanteans were rational scientists who caused the destruction of both civilizations with their scientific experiments.

The general consensus, however, is that the Lemurians were a race of peaceful and environmentally conscious, Shamanic vegetarians who focused their time and energies on spiritual growth and the development of their psychic abilities. Since they were able to communicate telepathically and to travell both by astral projection and teleportation, the Lemurians had little need for the scientific technologies of the Atlanteans. They did, however, discover how to use the spiritual technologies of crystal, solar, and sonic energetics for healing. The Lemurians also used their dreaming, imaginative, interspecies communication, meditative, and storytelling faculties to cultivate inner realization and enhance their intuitive willpower
