This is a good time to view part of National Geographic's Guns, Germs and Steel. This is a short series (available on Netflix) based on the groundbreaking work by Jared Diamond. I have mentioned the book several times. This link to the PBS is worth taking a look at.
The book is a good read, if a little overly technical in places. If you're interested in reading it, you can buy it here. I also have a copy if you want to (carefully and lovingly) borrow it.
