Now, this is something...
In this rather very informative work, to do not say heavily informative if this makes any sense at all, Dr Jared Diamond shows how today's world has been shape the way we know it today is due to geographical and environmental . This is why based upon Dr Diamond arguments our elders who had a head start in food production advanced a way beyond the hunter-gatherer stage, and then developed rules and regulations, and then germs and weapons of war appeared. Our elder decided then to go and see what was going else where so they started an amazing adventure crossing lands seas, and oceans, it resulted in conquest of less developed populations . Dr Jared keeps on going in its wonderful trip in time to make us understand human societies.
