Here is an author with an inquisitive mind. He searches, not how human races are different, but how they got there. What are the mechanisms that drove their various civilizations in such different trajectories? There exist only a limited number of plants and mammals that lend themselves to domestication and their availability determines the chances of hunter-gatherers to turn into a settled society and to progress in further advancement. In ancient times, if those essential domesticates were not present on your continent, you were indeed a have-not. In these pages you travel around the world and witness, how such factors have favored some sections of humanity more than others. This book is a wellspring of information about where we come from and the author distributes it out of a basket of abundant knowledge. You witness the changing face of humanity, usually under the passionate hand of brutality, from Khoisans to Bantus in Africa, from Negritos to Austro-Asians and Austronesians in the Far East, from the Ainus to Japanese, and then of course in that collision of the white man with the Redskins. The incredible judgment dispensed by Francisco Pizarro upon the Incas, supposedly in honor of the Church and the Holy Roman Emperor, will make you shake your head for a long time. In contrast to such scholarly research, it is hard to stomach the tasteless comments in some of the one-star reviews of this book. They remind you of what the Bible says about pearls and where you are not to cast them.
