Recommend a book: Guns, Germs and Steel (Jared Diamond)

Introduces the origin and development of civilizations in different areas around the world.
This book is fairly justicial in my opinion, though is a bit way too Geographic-political and lack of the data related to ancient India. Anyways, it is written in a style not so serious and is kind enough. Good to read and easy to enjoy.

Here, you can get, and ah, you'd better delete in 24 hours, and buy a legal copy anyway.
