Have humans evolved pheromones?

Pheromones are trace amounts of chemical substances secreted by organisms. They can be sensed by individuals of the same species, thereby precisely regulating their specific behaviors or physiological states. For example, insects use them for courtship, and ants use them for navigation.

Simply put, it's like a "silent chemical language" between organisms; it doesn't transmit ordinary information, but rather "command signals" that can directly trigger a response from the other party.

Currently, there is no scientific evidence to confirm the existence of pheromones in humans—that is, "chemical command signals" like those in insects and mice that can precisely trigger specific behaviors (such as courtship and following) within the same species.

However, humans secrete some chemicals (such as compounds in sweat) that may indirectly affect the mood or preferences of others, but the effect is very weak and lacks clear "directive" properties, unlike pheromones in the traditional sense.

[Fun fact: Rubbing your hands together for ten seconds like you're making a flower gesture can help you tell what you smell like (if it smells burnt, it means you're healthy)]

"After rubbing my wrists, they smelled like body lotion. I didn't shower today, so they must have really absorbed the smell [facepalm]"

"I also feel that everyone has their own scent, a scent that won't change even if you change your shampoo and shower gel. In high school, I could tell whose uniform it was just by smelling it [laughing and crying emoji], provided I had actually smelled that person before."

"It's true, everyone has a unique scent. My younger sister smells like wisteria, my middle school deskmate smells like milk, my cousin smells like pine, and my older cousin smells similar to my cousin. And every family has its own unique scent."

"Why does rubbing my hands smell like firecrackers? Are we trying to rub them together and create sparks?"

"When I'm with Crush, I always feel like he has a certain scent, maybe it's laundry detergent or a body odor, but it's not smelly, and I really like the smell, it's comforting [petrified]. I wonder if it's hormones [petrified]"

"A mother's scent is like a mother's scent; it's as if lovers can also smell that special fragrance between them."

"My boyfriend smells the strongest I've ever seen (not unpleasant, just very strong of his). Every time he comes to visit, my room is filled with his scent, and even after he leaves, my clothes still smell strongly of him, it feels like I'm wearing his clothes [laughing and crying emoji]"

"I guess it's the smell of hormones. When I first met my husband, if I spent a little time with him, I could smell his strong scent on my clothes and hair when I got home. But now it's gone after a while [laughing and crying emoji]"

"Oh, every family has its own unique flavor."

A person carries the scent of home, and home carries the scent of that person. Everyone has a different scent, but it is not static.

Some people's scent changes along with their personality. Some people smell really good, and I know I'll get along with them. Conversely, if someone's scent makes me uncomfortable, it's easy for things to go wrong.

"Yes, everyone's home smells different. The method is to be able to smell your own home the moment you return home after traveling for many days."

"Yes, and for example, when you come home wearing a mask and take it off, you can notice a unique smell in your house."

Lovers under the sky, spending all their time together whispering sweet nothings and pouring out their hearts to each other:

My friend always says that my Cheng Lang has a strange, pungent smell, which makes Cheng Lang very embarrassed every time he sees my friend.

I often have to bathe and burn incense before meeting my friends, which is more solemn than picking up a Buddha statue at a temple. I scolded my picky sister for this for a long time.

Cheng Lang is so handsome and refined. Even if he really does smell, bathing and changing clothes every three to five days is nothing like what she said. She's just nitpicking and making a fuss over nothing. She's finding fault where there is none.

Why is it that other people's noses aren't sensitive, but yours is? You can smell that there's a strange smell on him. I'm often with him, but I never smelled it.

You are my friend, that's true, but he is someone I like after all. Don't be too hard on him. (′△｀)

My friend with a sensitive sense of smell: That sly fox tries to seduce my sister You with his slutty scent all day long, and he doesn't even look very decent.

Sister You couldn't even smell it, and she scolded me. Did that vixen ruin her nose?

We clearly promised each other a sisterhood for life, but now she's heartbroken over a slutty guy who betrayed her sisters. I'm so ????﹏???????

If people really do have a smell, then the smell on me must be the bitter smell of copious herbs soaked in tears.

We've been playing together since we were little, we're even neighbors. And now you're saying these things about me because of a man? From now on, you can't come to me for sisterly love anymore!

During the Qin Dynasty.

As usual, Wang Ben was attending court when he once again encountered Prime Minister Li Si passing by.

Wang Ben scratched his head: I don't know why, but every time I see the Prime Minister walking over in the court, I can smell a scent of ink.

People say ink smells like ink, but it doesn't smell very good to me. Is there something wrong with my nose? Maybe I've been fighting for so long that I can't tell the difference between good and bad smells?

Li Si, who stayed up all night every day compiling laws and regulations: ...

Forget the scent of ink, this is the smell of cattle and horses of the sophisticated working class.

Want the secret recipe? If you switch to a civil service job, you can have it too. [The sinister intentions of a seasoned employee]

A senior student who often shared a dormitory with his juniors in a private school: Who understands the smell of feet among classmates?

Aside from initial resistance to taking off their shoes, they became increasingly enamored with the smell.

Now, it's not enough for me to just smell them in the classroom. After class, I have to stay in the house and sleep with them, secretly smelling them.

Ah, this scent, it's truly addictive! (?′w`?)

The more fragrant it is, the more stinky it becomes; the more fragrant it is, the more stinky it becomes; the more fragrant it is, the more stinky it becomes. Sometimes I really wish I could lie down at their feet and slurp it when they're half asleep. That feeling is indescribable.

You can understand, right? I really couldn't resist. If I weren't a scholar, upright and refined, and unwilling to lose face, I would have really gone up to properly appreciate the sweaty feet of my juniors.

How could there be such an irresistible flavor in the world!

Ancient rhinitis sufferers: What pheromone smell? Why can't I smell anything?

Could this be some random thing that Tianmu made up just to amuse people and deceive them? ╭(°A°`)╮

This situation is rare, but it has happened before.

Only with mutton and pork can I taste the distinct muttony smell of mutton and the gamey odor of pork. Oh, and some wild game from the mountains—I can smell the gamey odor of those too.

As for the rest, is it possible that humans, besides beasts, have a taste? Are humans the same as or different from beasts?
