DID YOU KNOW?
Ever wonder why chili peppers are so spicy? There’s a fascinating story of evolution behind that fiery flavor!
Chili peppers evolved capsaicin, the chemical responsible for their heat, as a natural defense against many mammals that might eat their fruits and destroy their seeds. But birds? They’re not bothered by capsaicin the way mammals are!
That’s good news for the pepper plant because birds can eat the spicy fruit, carry the seeds to new locations, and help the plant spread.
It’s a clever partnership:
The pepper provides the food, the bird spreads the seeds, and the plant gets a chance to grow somewhere new!
Next time you bite into a hot pepper, remember—you may be experiencing the result of millions of years of plant-and-animal evolution!
