There are a few ideas about the origin of the name funny bone. One is that the weird sensation can make you laugh and cry at the same time-kinda like when you're being tickled. Another is that the ulnar nerve runs through your humerus bone (the bone in the top part of your arm). LOL. Humorous! Okay, that's about as funny as hitting your funny bone-but it makes sense.
It is a human invention, a plant that does not exist naturally in the wild. It can only survive if planted and protected by humans. Scientists believe people living in central Mexico developed corn at least 7000 years ago. It was started from a wild grass called teosinte. Teosinte looked very different from our corn today. The kernels were small and were not placed close together like kernels on the husked ear of modern corn.
Spinach comes from a central and southwestern Asian gene center where it may have originated from Spinacia tetranda, which is still gathered as a wild edible green in Anatolia.
