I'm not familiar with the author and his works as this was gifted to me and well, this was honestly not what I expected. 

I didn't find the book interesting much, it felt like a bunch of facts and number glued together with no real sense to them, also the only part that really felt like it belonged to the book was the last third that seemed to be exactly what I thought this was supposed to talk about. 

From what I gathered from other readers, the two thirds of it is just repeating Homo Sapiens, that kind of makes sense considering how it was done and articulated. 

Honestly was disappointed.
