Ap World Ggs: Prologue

Spacious Skies and Tilted Axes

- Food production spread at different rates on different continents due to the geological structure of any specific continent, like in America, the land structure did not allow the processes of farming and herding to reach Native America from the US southwest.

- Agricultural innovation spread more rapidly from east to west in Eurasia, simply because the travel was more easy. Traveling north would cause you to enter climate zones different from your own, however from east to west, you could likely travel thousands of miles without encountering a change in climate.

- This caused some societies, specifically those either east or west of socieities that first developed farming techniques, to develop more rapidly and successfully then those in different climate zones, or to the north and south.

I agree with all Diamond stated in this chapter, as it was all fact-based

I mostly agree with Diamond about his nstatement that the crops of Europe and India werte most likely obtained from Southwest Asia and were not locally domesticated, as his example that wild flax, which occurs west of Britain, and has a similar mutation that occurred in other areas as well, suggesting a common ancestor.

I also agree with Diamond about his reasoning as to why farming methods and domestication spread more rapidly throughout Eurasia then in America, which was because Eurasia lies on a mostly east-west axis, which is the ideal type of axis for spread of ideas, as there is little climate change while traveling east-west. However, America lies mostly on a north-south axis, which was not ideal for the spreading of crop cultivation.
