Today, billions of people around the world start their day with caffeine. But how and why did the ability to produce this molecule independently evolve in multiple, distantly-related lineages of flowering plants, again and again?

What gets me about the cacao plant is that it generally is poisonous to most animals but one day, a human looked at it and said, “I’m gonna eat it.” And then didn’t die!

@jamesdeininger3759 Год назад

I’d be willing to bet that, throughout history, humans have tried consuming every single plant, fungal, and animal species they came in contact with.

The Maya and cacao are basically one in the same, they probably engineered it to be edible like maize.

@LithmusEarth Год назад

Tons of these plants, hot peppers, coffee, etc. are design evolutionarily to like kill the insects from eating them, a pesticide. BUT we are an insane species, who is like, Habaneros hurt... must eat more. I also like that our meat preservation habits, depend on what the average temperature & weather is, which determined the level of spice tolerance/use that that sector of the world required for that culture, so you get really heavy spicy food in india one of the hottest large ancient cultures, but relatively mild spice use in Germanic area.

My favorite little tidbit I discovered when researching the history of the cacao was finding out about a tribe in South America that became a huge "empire", for lack of a better word, by diplomacy with a lot of smaller tribes. Archaeologists found pottery that had traces of a cacao mixture laced with another chemical that could induce hallucinations. Basically, these guys were inviting their rivals over, drinking this hallucinogenic hot cocoa and then making a deal while they're all friendly and high.

I then cut the bare branches off for firewood but leave the canopy there for the bees. Everyone is happy - slowly the woods is being cleared so I will have paths and areas for new treevgrowth, goats think it is candy, I get firewood and the bees get both nectar and pollen from yaupon.

I love how plants produce chemicals entirely for their own benefit that end up creating an entirely different chemical reaction in humans. We then cultivate these plants, making them grow and proliferate more than the chemical's intended purpose ever could. And this isn't just for caffeine-bearing plants, too. Capsaicin in chili was made to deter all pests but birds, where the seeds pass through their digestive tracts unharmed. We said "nah, we like the burn", and proceeded to spread the chili further than any bird could. And it's not just plants we cultivate for food, either. There's cannabis and tobacco, which are billion-dollar industries.

@carolinacoreas7716 Год назад

Something I find interesting is how caffeine affects individuals with ADHD. I have ADHD and caffeine has never really given me an energy boost after the first time I tried it as a kid. I rarely ever drink soda, so I got my caffeine from coffee. I can usually sleep easily even when having drank more than my usual amount of caffeine. However, I still get the side effects of it such as an elevated heart rate, the laxative effect, and anxiety. I can be tired, but I get extreme anxiety if I drink too much coffee. Coffee has always been a sort of luxury drink for me because it tastes so good with creamer and sugar, and it's most likely for its stimulant effect of helping us produce more dopamine, which is something ADHD inhibits.

@adriennefloreen Год назад

That's interesting. I wake up shaking with my heart racing in the morning and drink coffee to feel calm and awake. And energy drinks like Red Bull don't get me very wired. Actually a few nights ago I woke up around 3am, couldn't find anything to drink but a Red Bull, so I drank one and went back to bed for a few more hours. Do I have ADHD? Probably I guess, I am quite a hyper person.

@carolinacoreas7716 Год назад

@@adriennefloreen so, the thing is, not all people with ADHD fit the stereotypical image of a hyper person. In fact, the most common subtype of ADHD in women is the inattentive subtype. However, some things affect most people with ADHD in similar ways regardless of which subtype they have. The condition itself has to do with the low production of dopamine and epinephrine, but mostly dopamine, which impacts one's executive function. The fact that you wake up shaking and the only thing that can calm you down and be awake is caffeine sounds more like symptoms of withdrawal. So it has less to do with the probability that you have ADHD and more with the probability that you're addicted to caffeine and your body undergoes moderate withdrawal symptoms when your caffeine levels run low.

There at least 2 identified genes related to that. One is like a resistance to caffeine's effect and the other makes some metabolize it more quickly (this lessening the effect).

@TheKaneECO Год назад

According to some research it's apparently much better to drink coffee about 90 minutes after you wake up opposed to right away. This was you avoid a crash later. The reason is that in the morning you have a lot of adenosine in your brain so by blocking the receptors all of it just sits there waiting to bind to the receptors when the caffine wears off. Giving yourself an hour or so allows the left over adenosine to bind and wear off so you don't crash super hard when it kicks in later all at once.

In school, we had a chapter in our Hindi literature subject on The Shepard's story discovering coffee berries. It was elaborate and beautiful. I remember the smile on our teacher's face when she came to the part of the Shepard discovering the smell of the roasting coffee. Teachers are our one of the first storytellers indeed.

What I find most fascinating is the plants you mention are all bitter tasting. In general it makes sense to avoid anything naturally bitter because it's a sign of danger/poison (obviously not all the time, but it could be argued caffeine is dangerous due to preventing the body feeling tired, as well as addiction), yet humans choose foods like coffee and chocolate, often adding a lot of dairy and sugar to make it palatable. I would love to see a video about how and why we learned to prepare certain foods in different ways.

@CatFish107 3 месяца назад

Caffeine in a dose equivalent to filling your stomach with chewed tea leaves would probably have some severe negative effects on a human, or other mammals. It is quite interesting how we've adapted various plants and preparation methods to make them edible.

@gregorysagegreene Год назад

Fascinating. The fact that 'chemical evolution' can separately evolve alternate convergent pathways to the same end, which then gets 'selected' at the macro-eukaryote organism level, is a strong indicator of the sheer vastness of 'deep time'. On the underpinning molecular drivers, Darwin's mind would be blown.

This makes me think about the "plants are poison" people who claim eating any plants is toxic to humans. The most ironic thing about them is the vast majority of them depend on caffeine to get through the day.

Hi Eons team, I'd love to see a video on the evolution of dingoes. I'm curious to learn more about where they came from and whether they were domesticated by the Aboriginal and Torres Strait Islander peoples. It would also be interesting to see an episode on thylacines and Tasmanian devils

@EricRoberts2112 Год назад

And why they steal babies lol

@theairstig9164 Год назад

Wild dogs ate all the devils and Tasmanian tigers on the mainland. The dingo is genetically related to the Asiatic wolf and has lived in Australia for about 4000 years. Therefore they did not arrive by land bridge. They arrived by boat with people. The 4000 years comes from measuring the genetic mutations from the Asiatic wolf then dividing these by the average breeding age of the animal

Weird how there aren’t any caffeine producing mushrooms (so far as I know - correct me if wrong). Alkaloids are pretty common in the fungus world, so you’d have thought one would’ve hit on caffeine.

@juanausensi499 Год назад

Probably they don't have the same chemical precursors as plants. But they have they own version of everything, so probably there is a mushroom out there that doesn't make caffeine but something that acts similar.

@regorflora7915 Год назад

@saferugdev8975 Год назад

not sure if its just me, but taking small amounts of magic mushrooms has a very very similar effect on my brain as coffee. the effect being a clear mind and high concentration. besides that i am very sure that there has been, at least at some point, a mushroom producing caffeine, as there are literally millions of mushroom subspecies, of which we have only discovered around 1%

@Hyenalowena Год назад

Ultra simplistic version: it's because caffeine is a stimulant, and stimulants affect the production of dopamine, which helps control focus and calmness. People with ADHD have dopamine regulation problems. So instead of making you more peppy, caffeine is helping to level things out to make you feel more chill.
