Why The West Rules For Now and Guns, Germs and Steel
Guns, Germs and Steel is such a really, really, really bad book
It doesn't offer a single source for anything it says, and almost anything it says of any significance is demonstrably incorrect:

And seriously, think about how absurd the premise of this book is:
Environmental differences in different parts of the world are large enough to explain why grand civilizations flourished in Europe and Asia but Australia and Sub-saharan Africa didn't progress beyond hunter gatherer societies....but these differences weren't large enough to result in ANY differences in selective pressures between these places other than for skin color etc.
