First off I have to say that this is a very cool idea! I have never been part of a blog so this is going to be a great experience.
In Chapter One, the author talks about the Agricultural Revolution as the time when human civilizations began, but he also makes a point to say that some scholars believed this to be false and that some civilizations had developed years before. For me, I believe that no matter when human civilization began, the agricultural revolution was a major turning point for the way humans lived. It started the idea of land ownership and property value, which led to the different tribes defending the land and/or seeking out more land. This is the first example in human history when you start to see different human tribes fighting for land. This is important because this is the time when you start to see human behavior similar to what we see today. Wars over land still happen today just like they did when it started those thousands of years ago.
