The History and Science of Chili Peppers: Why Humans Love the Burn
TLDR Chili peppers evolved capsaicin to deter mammals from eating them, but birds are not affected by capsaicin and can eat the peppers, allowing the seeds to pass through their digestive system and grow into new plants. Early humans in South America were attracted to peppers because they made bland starchy food more flavorful and easier to digest, and evidence from the archaeological site of El Brujo in Peru suggests that people were eating spicy peppers as early as seven and a half thousand years ago.
