Sometimes when an elderly person falls and ends up with a broken hip, it’s actually the hip breaking that causes the fall.

Supposedly global warming will cause spiders to slowly get bigger overtime.

Pinky toes can auto amputate. It's exactly what it sounds like, and once it starts, you can't stop it.

The chainsaw was originally a medical tool used during birth. They cut your pelvis in half to help get the baby out. It was invented in the 1800s and was hand powered.

Spiders have exoskeletons that they shed. When you see a dead spider, it might not be a dead spider. It could just be it's old skin, and the spider is now somewhere else, and bigger.

On very rare occasions, a corpse can ‘give birth’. If a pregnant person dies, then certain results of decomposition, such as bloating, can force the fetus out of the womb, giving the illusion of Corpse Birth.

That the leading cause of death for a pregnant woman is m*rder.

Honey. Let's follow these highly territorial murder flies to their stronghold and eat their vomit.

That's easy, watch a bear. It's kind of a cliche now because of cartoons but bears LOVE honey, and will climb trees to get to the hive. Probably doesn't hurt that their skin is thicker and getting stung probably tickles, but they will go to some lengths to get it."

"Some enterprising caveman watched the bear go for the hive and probably decided to taste what was left. I wouldn't want to fight the bear for it but it probably was the first sweet thing ever tasted other than fruit, so it was valued."

The enigmatic durian – a fruit so pungent it could make a skunk blush. It's like someone stumbled upon this spikey orb, dared to take a bite, and thought, "Yes, let's create a culinary sensation that smells like a blend of rotten onions and gym socks." Truly, the mysteries of gastronomy know no bounds!

Artichokes.

I kinda feel like they're a specialization from a generalization though.
There are the more generalized Cardoon thistles where you more eat the stalk and stems which wouldn't be that big of a stretch to throw them on some coals, peel, and enjoy. Later someone found that the flower base was even better because you can use it as a bunch of tiny spoons to deliver copious amounts of butter to your cardoon hole.

Hakarl. I think it was probably starvation that led someone long, long ago to eat that rotten dead shark that had been fermenting in beach sand for months. Surely that could be the only reason someone would eat it because I have heard hakarl smells and tastes like p**s.

Maybe not quite food, but like tobacco and Marijuana. The amount of trial and error of just smoking random things to see what happens must have been an interesting time.

Steamed-Barley reply:
It's brewed from a combination of Chacruna leaves and the vines of Banisteriopsis caapi - two completely different plants. The leaves contain DMT, while the vines contain MAOIs, which inhibit enzymes and allow DMT to enter the bloodstream and reach the brain. Both are necessary for the potent psychoactive effects to occur, you can't take one without the other.
It's been used since at least 1000 years ago. How the hell they found the correct combination is just... wow.

Ever think about coffee beans? Hey, I'm gonna roast this seed, smash it up and drown it in hot water. Bet it tastes great.'.

TheFerricGenum reply:
This one is not that difficult to come by. The beans are edible when freshly picked, and actually contain more caffeine (caffeine is lost through baking). So I bet people were regularly drawing on these as a food source since they are an upper. Someone along the line probably realized cooking things can keep them from spoiling a bit longer and started roasting their beans. If food was scarce, it’s possible they boiled these beans at one point to try to stretch their food supply. They liked the taste, and realized grinding the beans helped draw out the flavor easier.

Fugu. To even be allowed to make it, you need a license to show that you can consistently make it in a way that won‘t kill your customer(not to mention the training required to get the license which IIRC can only be issued by the Japanese Government). How many tries were needed to figure out the propper way to make it and why did they keep trying after the first two or three tries?

SeiCalros reply:
Fugu fish aren't that lethal. Most people could eat a whole fish including the skin liver and ovaries which are the poisonous parts. One fugu fish COULD be fatal but most people who used to die from fugu liver had eaten several of them.

Our earliest ancestors in Africa likely ate a ton of yams, which were basically hard roots that I believe are also sometimes toxic. People were probably dead set on making the root vegetables where they ended up edible. Eating root vegetables as a staple might be the most engrained human tradition.

Almost every edible mushroom. Lots of trial and error there, I bet.
shadowa1ien reply:
Shiitake mushrooms are like this. They're not deathly poisonous, but if eaten raw in medium to large amounts can cause severe itching for up to several weeks. Now imagine my face as I read that little tidbit on Google... after I had popped a raw shiitake mushroom in my mouth and had already swallowed most of it. The moral of the story, if you aren't sure, google before taste testing. my logic was since there's no warning on the store packaging, it must be fine! I didn't get the severe itching thankfully.

The amount of effort you have to go through to make cashews edible

The f**k did someone figure that out.

Maleficent_Nobody_75 reply:
Yes. The shells that surround the cashews apparently contain very toxic oils and the extraction process they need to do can be hazardous to us humans if not handled correctly. The extraction process has to be done manually, hence why the process is difficult and time-consuming. Probably the reason why they are one of the most expensive nuts on the market when I think about it.

Chocolate. I mean don't get me wrong I get why they were playing around with the plant and all.

The sheer process of getting to Chocolate as a product is so weird and bizarre and kinda gross...and then it comes out as the lovely candy we know and love.
