The book, On the Destiny of Species: by Means of Natural Selection, or the Elimination of Unfavoured Races in the Struggle for Life by Matthew Watkinson. Watkinson’s basic premise is this: Species that do badly in the “survival of the fittest” game should not be conserved. The Nazis have done this with people before; it’s call egugenics.
The book is for sale in Amazon.com but hmmm…, I wonder why the author is giving it away for free. Zero sales, perhaps?
