It's just relative. Most mammals don't pay rent, taxes, or have to deal with the TSA. Once you do those things, spicy plant chemicals become a frivolous game.
There's a book called The Botany of Desire, by Michael Pollan, which is about this. Looking from the plants eye view of things, they have manipulated us into growing them in a huge variety of environments. The book focuses on tulips, cannabis, apples, and potatoes, iirc. Fascinating book.
Two quick examples from the book:
Pot gets us high, now we grow it in closets, warehouses, yards, basements, attics, etc.
Apples don't reproduce true from seed, so Johnny Appleseed brought readily available cider to the Americas. (You need a cutting of an apple tree to grow that type of apple.)
Humans: I will now cultivate you, export you, protect you and make sure you're growing well so I can keep smoking you despite a 50% chance of dying from it.
It's funny if you think about it: Plant makes chemical (capsaicin) to help it thrive > humans love the painful spice, start growing and propagating peppers > Peppers spread grow like crazy. Evolution working exactly as it should
Sriracha is now completely random from bottle to bottle. It goes from Tabasco to Carolina Reaper with no visual indicator. Turns out fucking over your loyal farmers and having to constantly scrounge has negative consequences…
Is Tabasco delicious? I find the Sriracha from couple of years ago delicious (the current one is much worse), but Tabasco always tasted like a white vinegar mixed with capsaicin.
the only hot sauce i've yet to actually find appealing is sambal olek, somehow the heat in that just makes me salivate and kinda feels more like sourness, as opposed to everything else where it's just pain and like.. no real flavour? with sambal olek i can actually taste the flavour in it.
Does anyone have an explanation for why they would evolve to prevent being eaten by mammals? I would think having mammals help spread their seeds would be beneficial?
Adding to the other responses, birds have simple digestion systems and the seed makes it into the poop, which birds do in flight so the seed will spread. Mammals digestive systems would destroy the seeds before they can spread
Well, not all of you. We'll massacre and purge your more moderate siblings and cousins, but we really like YOU, so we're gonna clone you as much as we can.
Huy Fong branded Sriracha. It’s the worst option because they fucked over their pepper suppliers so the quality is terrible now. Get any other kind of Sriracha and it’ll be better.
