4.5 stars 
 As the title says this is an extremely BRIEF history of Humankind, starting all the way back with the rise of the Sapiens species. It focuses on the Cognitive, Agricultural and Scientific revolutions and how they contributed to the dominance of Humankind. 
 The book is very intriguing, eye-opening, informative and definitely changes your viewpoint of the world. It got my attention right away with the different species of Humans and what made the Sapiens so special. It was fascinating to see how so many different cultures, societies, religions and ideologies affected and helped each other get the human race to where we are today. 
 The last few chapters of the book are thrilling, exciting, scary and very thought-provoking about the future of mankind. 
 I felt the writer was trying to convince me of his opinion in certain aspects rather than letting the truth/history speak for itself. Still I admire the great amount of research he went through to create this book.
