Andrew Collins' new book is out entitled "The Cygnus Key: The Denisovan Legacy, Göbekli Tepe, and the Birth of Egypt".

Wow there is a lot of information in this book. Note that there is also a lot of speculation. 

The good side of this book is to expose readers to much about the history of modern humans that has not been fully exposed before. Concepts concerning the origins of common myths and beliefs found around the world are traced back a possible single origin point. Precession and its impact on human psyche is examined in great detail. It presents an excellent summary of what is know of that area in Southern Siberia that is associated with the genetic mixing of the Homo Sapiens, Neanderthals and Denisovan. I very much like Collins' investigation of the pyramids of Giza and their alignment with the constellation Cygnus. As I said, there are lots of interesting themes presented.

The challenge of the book is to keep in mind that although Collins presents a very good story that links the many topics, many of the connections are by no means confirmed. Yes they might be true, but they are certainly not proven. In the best of worlds this will allow for more detailed investigation and exploration as we go forward. 

The discriminating reader should be able to make their way through the many points with a mind to become aware of, and to actively question, the many unknowns that remain about our development since the last glacial maximum - but it is not an easy read. Specifically if one is not aware of the many points of argument, there will be much information to be digested. 

I would have preferred the story laid out in time from start to finish instead of in the present form that tends to jump around in time from 10,000 BCE, to 5,000 BCE to 20,000 BCE.
