Wasn’t corn a New World plant that never originally grew in Africa?
Don't try to tell an afrocentric that though. He/she/it will assure you that you are racist.
I saw that happen when an anthropologist tried to explain that horses evolved in the New World, were hunted to eradication by prehistoric indigenous peoples and were unknown here when the Spaniards brought modern horses with them.
An "afrocentric scholar" who was present acted like he was a genocidal maniac, because you see everything worthwhile originated in Africa, including the first airplanes.
