Coffee plant: *evolves caffeine* Safe at last

Humans: ( ͡° ͜ʖ ͡°)

Literally any strong flavors or effects that humans eat were evolved as protection.

Mint? Yep.
Mustard? Yep.
Cinnamon? Yep.
Caffeine? Yep.
Hot peppers? Yep.
Peppercorns? Yep.
Rosemary?

Yep.

Thyme?

Yep.

Basil?

Yep.

Garlic? Yep.
Onions? Yep.

Humans learned to like the flavor of plants that were supposed to be unpleasant to other animals because we constantly crave new experiences and get bored very easily.

Basically, we’ll eat anything that doesn’t kill us and call it food.
