Guns Germs and Steel

<p>Has anyone read Guns, Germs, and Steel by Jared Diamond?</p>

<p>If so, can you give a short summary of what kinds of things he talks about? Like are there any recurring themes?</p>

<p>I have an assignment due tomorrow (not these questions, I have to respond to a couple of quotations).</p>

<p>Thanks :).</p>
