Why Don’t Humans Have Whiskers?

  • You might have a beard, or a moustache, or even a soul patch. What you don't have are whiskers.

    Does it not have anything to do with the fact that most animals that do have whiskers seem to travel head first as it were, whereas because we stand upright the most extended part of a human in the same direction that we typically travel is the finger tips?

    When you think of whiskers most people probably think of rodents, cats and dogs etc. But what many people might not now is that even horses have whiskers. They use them to feel what they have under their noses when they eat or drink, something they need to do because they have a blind spot right in front of their faces (they can't see the grass they're eating when they graze, they can't see an obstacle in the middle of the jump etc.) So for my fellow horse people out there, please don't trim your horse's whiskers!

    I've had what seemed like true whiskers, including the extra sensitivity, occasionally sprout from my eyebrows and earlobes since about the time I turned forty. They are annoying as well as unsightly, so I pluck them out as soon as I notice them. In recent years this has become an uncommon occurrence, so maybe I've already pulled out the follicles that were susceptible to this transformation.

    Humans lost a piece of a chromosome cause other apes to have:

    1. Whiskers: We use the brain space for touch in our fingers.

    2.Penile: spines which are really spikes that rub against the vagina and causes males to come instantly. Copulation only last seconds and the males move on. It seems only human females have orgasms.

    3. Kills brain cells. Mammals make too many brain cells and kill most of them in the womb. Humans make use of those extra brain cells.

    Humans pretty much use eyelashes as whiskers.
    They are what lets us shield our eyes with eyelids as soon as something suddenly comes anywhere close to our eyes. But their effectiveness is limited by our slow reaction time.

  • TheHelleri
    TheHelleri 3 months ago

    I think being bipedal is probably a big part of why the change occurred. We don't interact with the world physically head first. Other primates still do to some degree. So them having at least small whiskers makes sense. While it's true that animals sometimes hold onto useless traits just because those traits are benign (i.e. not effecting their ability to pass on their genes). In general form follows function. That are fingertips are so sensitive to touch is evidence of it. That's how we encounter the world physically. So it makes sense that our fingers function as whiskers.

    Tells us about the parietal eye now, Hank. Why don't humans have three eyes like our ancestors did.

    Or just talk about the parietal eye and the pineal gland if you haven't yet. I think it would be a good topic.

    Nothing labelled as vestigial is actually vestigial. Never has been, never will be. Just because some people don't know what something is used for, doesn't mean it doesn't have a use. Without looking it up, close to 100% of people have no idea what hydrodilatation is. I learnt the hard way.

    Hank, your rapidly successing facial hair styles terrified me momentarily. Do you think you could do a supplementary video on the topic of convergent evolutionary traits? I loved viewing content explaining the genetic expression of whiskers in mammals, but I am dying to know more about catfish's whiskers; as they are bottomfeedeers in what we humans would describe as "zero visibility conditions."
