    Humans like water more than most primates, and a diet rich in seafood would help support brain growth. Im not arguing for the full "aquatic ape" nonsense here, but a handful of minor adaptations to dabble in shoreline food collection goes a long way toward explaining some odd human morphologues.
    For the nose, thus would give us down-turned nostrils that would help prevent inhaling water when swimming.
    Worth noting that another primate with a similar nose, the proboscus monkey, lives on an island chain and swims much more often that most monkeys.

    We are also the only primates to feature a chin. The reason is: biophysics. Quick summary: chewing produces the highest pressure bones have to withstand in all of our body. Bones have to adapt their shape in order to withstand those pressures. So, chewing determines the shape of the face and the skull. Bonus feature: a bigger skull volume.

    I like this theory, but I'd also heard that it might also have something to do with us having evolved to live in drier environments so needed a longer nasal passage to allow the air to be humidified - apparently the baboon is similar to us in this respect. Contrast this to gorillas, chimps and orangutans who live in more humid areas so have far flatter noses.

    I kinda think that our protruding noses also protect the eyes a little bit. A few times in the past I've had shrapnel strike my nose on an angle and be blocked from entering my eyes. It would also work when slamming your face against something, your nose prevents your face to directly strike flat against the surface and keeps the eyes a little further back, combined with the brow ridge. I imagine this might have had the unintended side effect of preventing our ancestors from going blind during their hunting/fleeing/fighting and allowed them to live to reproduce
    I understand that this is highly unlikely but it might be part of it? I don't know.

    @SciShow I always thought that our noses are convergently evolved for the same reason for big olfactory chambers in grazers in desserts and tundras. Hominids first started to evolve around the global climate shift away from rainforest toward savanna and desserts. Ice age and Sahara expansion would mean dryer air. I thought our noses first protrude to compensate for Africa's and Asia's desserts which we would have to cross for first hominid migrations out of Africa. I theorize that wide noses appeared first to condition arid air without much moisture loss. Then more pointy noses may have evolved later in cold climates with greater internal surface area for heating cold air while inhaling. I wounder, do other apes' noses drip snot like ours do in dusty or cold conditions? Is there also a link with the evolution of buts/ ankles/ running too (linked to same climate transition too and coevolved)? Do our noses also allow a faster air flow rate for rapid breaths (associated with running and physical activity during more active persistence-hunting lifestyle)?

    Doing a somersault in the water fills the sinuses up and not fun, but maybe fishing for crabs or shellfish when you duck just under the water, those handy little "upside down cups" might help?
    Then dust.. or sand. Snow?

    I don't see why shoving different parts of the splanchnochranium around should have enlarged our nose. Indeed, the argument presented is that the human splanchnocranium got SMALLER, yet the nose cartilages got BIGGER compared to the homologous ones in large apes. And wouldn't whatever embryological growth restrictions keep our lower face and jaw from extending outward very likely apply equally to the schnoze, unless there was some good reason why it should protrude? Also, I believe that sensory-motor brain function is sufficiently well mapped that they could make pretty good estimates of how much of an increase was required to maintain upright posture, and don't forget, little Lucy, Australopithicus afarensis, was also a habitual upright walker. Sounds like time for more brainstorming....

I'd hope this would not unlock a new fear for people, but provide some thoughtful information about it.

We always get wildfires during summer, but that day the dry weather and wind made it spiral out of control. Whole ancient forests, villages, industrial areas, the whole country turned to hell. Firefighter captains were literally crying on TV because they were powerless to attend all the outbreaks and saw the distruction first hand. What saved the bigger villages and cities? Civilians being on prevention too and putting out any outbreak while still small. We were only saved because the next day it started raining.

Unfortunately, the Civil Protection/Firefighters communication system wasn't prepared for something that deployed every single one of them. Even with planning sometimes things still fail!
      Here, the larger the city the less threatened it felt, the way we build, the materials used (we hardly use wood), our experience since the 1775 earthquake followed by a tsunami and then fires that destroyed most of Lisbon, have made cities (especially the more recent constructions) safe enough.

    Read The Scars of Evolution by Elaine Morgan. Hydrodynamics explains it. We were semi aquatic 2 million years ago. Swimming explains all of our differences from other hominids and apes.

    or....there is also the water ape theory, where earlier versions from us lived a lot in/near the water. charateristics of such animals: nose holes going downwards (better for swimming), skin cannot be lifted away from the flesh. Not true for primates, but for humans. Ever asked yourself, why in hell people like to go to the beach and see this as the nicest place ever?

    My favourite evolutionary theory around how humans evolved is the Aquatic Ape Hypothesis (AAH).
    Which provides so many reasonable explanations as to many of the differences between our great ape cousins.
    The H. sapiens nose is excellent for diving under water.
    Also another factor to consider is how folks who live in colder climes appear to have bigger noses than those in the Tropics. So warming air may also be a benefit to big downwards facing noses.
    The only other primate that shares a similar nose is the Proboscis monkey which is both endowed with a large nose and the ability to swim in the swamps it inhabits in SE Asia.

      I feel like that theory is a solution looking for a problem.
      Like they saw the Proboscis Monkey, which is the only other monkey/ape with a big nose and thought "Well, they swim, and the others don't, therefor our noses are because of water".

    I wonder how much environmental dust effects how much the nose sticks out. in my dusty spanish town, a lot of migrant kids from africa and south america with flatter noses with larger nostrils always had problems with congestion. if the nostrils are pointing more downwards that horizontal, wouldnt that decrease how much dust enters the nose? more certain is that a larger nasal cavity would stop more dust from entering the throat and lungs. a larger nasal cavity also makes the air we breath more humid and warm, so ethnicities which evolved in dry, dusty or cold environments should have larger noses.

    It seems like most of the human nose is composed of cartilage and flesh as opposed to bone. If i were to guess, i'd say that the nose's function is to filter and warm incoming air. Is it possible that as our brains occupied more and more of our skulls that those functions, possibly once performed inside our skulls, were moved to a fleshy protuberance outside of the skull?

    Another hypothesis: early humans spend a lot of time in the water. That’s the reason we lost most of our body hair. A nose with downward nostrils could help to avoid water in their noses, while they are in an upward position in the water. Do a flip turn under water and you’ll see what I mean. For the downward position of the nostrils, the nose has to stick out.

    When I was very young, my underdeveloped mind had the genius idea to remove the object obstructing my vision. I tried to cut my own nose off with a pair of scissors. I ??fortunately?? botched the attempt. I do however have a smiling scar on my upper lip to this day. It taught me an important lesson at a young age to love and respect every aspect of my body, no matter how annoying some "features" are.

    I remember years ago, one idea had been that, amongst other things, your nose acts like a bumper on a car if you fall over or smack your face. It's more likely to get hit first and protect the other bits. Yes it's going to hurt like heck but it's better than losing your teeth etc.

  • @tfsheahan2265

    What about the hypothesis that our downward pointing nostrils evolved from a semi-aquatic lifestyle, because it made it easier for our ancestors to swim and harness the oceanic food web, even as is the case for much of the human race today?
