Query: A well argued review of the history of us all.

Mr. Diamond provides a thorough and enjoyable account of the origins of human society and the factors that determined the locations and natures of these societies.Although at points theoretical (as any work of this scope is destined to always be) I found the evidence presented both entirely compelling and interesting. While there are those who would readily question the author's reliance on geographical factors as the sole influence on the development of human societies, I personally find the theory quite applaudable and impressive.This timely work should play a great part in putting to rest the racist views long held by many who speculated on the factors influencing the development of human societies.Very, very well done. The only reason I have not given the full five stars was I would have liked to see the section on linguistics elaborated on a little more (although it is more likely than not my bias alone, being interested in the topic).
