Yam migration map

I created this map in Google maps to show where different types of yams originated and where they migrated to. Of course, you can find yams all over the world and with the internet you can have yams delivered right to your house without having to travel around the world.

What's really interesting about yams is that they are not only often confused with sweet potato, but also yuca aka cassava, taro, and other root vegetables.
