Ron Newby - Tribalism - An Existential Threat To Humanity (Lulu, 2020) *

"Tribalism" is a collection of insights on the broad topic of human evolution leading up to today's global challenges. It is bacly written, badly published, possibly not even corrected for mistakes ... and if you want to see the picture that illustrates the text, you get the full URL so you can check yourself on Wikipedia. 

The book goes into a lot of detail on irrelevant facts that have nothing to do with 'tribalism'. I can understand that Newby is shocked in a way by the upcoming nationalism and tribal ingroup behaviour, but his book does not shed light on the problem itself, let alone on the solutions. 

The topic obviously deserves better.
