Today I learned that corn is alkaline and that some corn was selectively breed in Europe. I was under the USA-centric assumption that humans found corn in Mexico and was brought north then natives gave it to the pilgrims and thats how we got our corn for the 4th of July.😃😅😂
I had never really thought about seeds going from the "New World" back to Europe to be domesticated for mass production.
I actually don't know how corn was spread on the American continent, but the decription is found in one of the oldest history book from written by a member of the elite. The same was actually done to potato and the peasants didn't want to grow it and eat it because they didn't know how. At first they ate the upper parts of the plant, at least they say so. To me it looks like this is somehow done with practically everything, even nowadays.
