This book, Milton Brener's third on the subject of UFOs and extraterrestrials, is a giant leap. He delves into an analysis of much current scientific evidence that appears to add credence to claims of early hybridization of the human race. It is an entirely new and novel approach, but a very readable and one. It is a challenge to readers to think constructively of the new and novel. It revolves around the coalescence beginning about fifty thousand years ago of several significant and scientifically proven occurrences. One is the beginning of the pale skin tone of Europeans. Brener systematically dismantles the accepted scientific explanation for it and drives home the fact that the only other living creatures with similar skin tone are the extraterrestrials, often known to many witnesses of high credibility as Nordics. Unlike other ETs, these Nordics look like us, though some are said to be remarkably tall and, also unlike others, leave the contactees with very positive feelings. Another major occurrence, the great transition, was the relatively sudden appearance of modern behavior, including artistic genius, timekeeping, and creation of musical instruments. The book is truly a tour de force.
