Today, chilis are the most widely cultivated spice crop in the world - grown everywhere from their native home in the Americas to Europe, Africa, and Asia. But how and why did chilis evolve this weird, fiery trick in the first place? And why did we learn to love that spicy burn?

    I make a range of fresh produce range of jalapeno,chilly and habanero sauces. I would have to disagree with the illusionary notion mentioned in this video. I have physically prepared thousands of hot peppers so far ,transient rashes and inflamation of the skin is more than just an illusion its an actual interaction between the chemical of the pepper and skin. Touch enough hot peppers without gloves and you may even lose skin on your finger tips!

    Definitely addicting. I started my spice journey with a Slim Jim (Mild) at around 4 years old. My love for spicy foods grew from there. From that point on, I just worked my way up the spice ladder, eventually growing my own peppers in my teen years (jalapeno, banana, cayenne, tabasco, and habanero peppers). I used to make salsa with them. Through adulthood I have enjoyed the wide range of extra hot peppers, ghost, scorpion, and so on. Great video!

    Chilis aren't the only genus that has benefited greatly from humans' eating habits. There are currently more chickens than people in the world -- pretty good for a domesticated version of the red jungle fowl. Ruminants like cows, sheep, and goats are doing well, too. When vat or 3D printed meat becomes cheaper than regular meat, the population of those meat animals will plummet. Hopefully, someone will keep at least some around so that they don't go extinct.
