Isn't it obvious?

"In short, Europe's colonization of Africa had nothing to do with differences between European and African people themselves, as white racists assume. Rather, it was due to accidents of geography and biogeography-in particular, to the continents' different areas, axes, and suites of wild plant and animal species. That is, the different historical trajectories of Africa and Europe stem ultimately from differences in real estate."(400-401)

Ultimately I believe that simply with the presentation of this quote a guilty verdict can be drawn in the case of determining whether Jared Diamond is guilty of geographical determinance or not. Second of all, I believed that that is what the book was meant to explain. Throughout the entire work, Diamond blames geography. He spends most of the book narrating the differences between the conditions within the different continents. The biggest and best example of geographical determinance that he gives is that of the different rates of advancement in the Polynesian islands. Here he spends an extensive amount of time describing the different geographical elements of each of the islands and the way those elements affected whether one society became more advanced and was the conquerer or the conquered. I believe there isn't much to discuss about this topic because Diamond is obviously a geographical determinist.
