Silbury Dawning

The book Silbury Dawning presents the unique theory that the 'missing link' in evolution was due to the arrival of an extra-terrestrial being or race of beings some 13,000 years ago that bred with, or somehow implanted its genetic material and educated our Homo sapiens ancestors. As per Darwin's theory, those Homo sapiens with the Alien Visitor gene had a significant advantage and began to replace those that didn't - resulting in the human race that quickly evolved from a single point.
