Human Devolution, the sequel to Forbidden Archeology, presents a Vedic alternative to the currently dominant theory of human origins. Most scientists now believe that humans of the modern type emerged between one and two hundred thousand years ago, having evolved from more primitive apelike hominids. But there is a significant amount of archeological evidence, in the form of anatomically modern human skeletal remains, footprints, and artifacts, showing that humans of our type have existed in the very distant past, at times the current theory cannot accommodate. Furthermore, genetic evidence, although suggestive, has not definitively established humanity's evolutionary origin from ancient apes. Therefore there is a genuine need for an alternative explanation.

But before we ask the question "where did human beings come from?" we should first of all ask the question "what is a human being?" Today most scientists believe humans are simply combinations of ordinary matter. But if we consider all the evidence that comes to us from various fields of research, we shall see that it is more reasonable to say that a human being is a combination of three things: matter, mind, and consciousness (or spirit). Of the three, consciousness is primary. We do not evolve up from matter, but rather we devolve, or come down, from a realm of pure consciousness or spirit. During this devolutionary process, the conscious self is covered by mind and matter. But the process can be reversed, through spiritual re-evolution. And that is the primary purpose of human existence, which is now burdened by too much concentration on the exploitation of matter.
