This sounds like stupid shit I'd assign majors to get rid of them. Is this homework or what?
don't get your point? Are you saying this is not a valid topic to discuss?
Some people were arguing that our food turning soft after the invention of agriculture has reduced our palate size, leading to crowded teeth. So the thinking is that evolutionary remains found of early humans usually have straight teeth because they ate hard foods like meat.
Additionally, there is a doctor online I follow, Mike Mew, who states that childhood habits of mouth breathing lead to a recessed jaw and that the proper breathing technique can have a significant effect on our facial structures. This guy has had his trouble with governing bodies, but he has a jaw made of steel (it makes you ask whether his advice is legit).
My observation is that existing hunter-gatherer uncontacted populations that still follow a traditional diet don't show consistent dominant facial features. Additionally, some mouth breathers I know still have well-defined facial structures.
My question is there any solid science providing an answer to this question? If so, is it correlation or causation? And to what extent are the above factors determinants of facial outcomes?
I attach here some of the research showing a correlation between jaw development and chewing hard foods: link1 and link2.

I saw something recently that suggested humans head/jaws have been getting smaller over the last 30ish thousand years and our teeth have stayed the same size, as well as retaining our wisdom teeth, hence the crowding we see now, not sure how linked to diet it was but still interesting
ok, it might just not be related to diet and maybe only to genetics.....
Mike Mew? As in mewing? The pseudoscience behind making your jaw chiseled?
Yeah, his father invented mewing, and he was doing that since he was a kid. He has a chiseled jaw, even though his brothers don't have the same result. I don't know if mewing is scientific, though; that's why I am asking. But I heard resting your tongue on the top of your palate is a natural posture, and other forms are deemed disordered.
I never thought I would see mewing mentioned on this sub (to clarify, yes, it's pseudoscientific) He is indeed the son of John Mew & was struck from the dental register
Mewing is named after a person? Why did I think it was named after a cat.
The fact that chronic allergies cause changes in facial structure is actually well established; thought to be in large part because of the increase in mouth breathing. This review article describes it a bit more: https://www.frontiersin.org/journals/allergy/articles/10.3389/falgy.2025.1650119/full
Yeah, I guessed the same thing. But some people are also mouth breathers and still have great facial structures, and I was guessing if it is one of the environmental factors contributing to genetics.
I just wanted to add - The idea of chewing soft food influencing jaw structure is at all controversial in the developmental world. People tend to think of musculature as completely malleable and skeletal structure as completely rigid, neither of which are true. Both muscles and bones are organs in their own right. Muscle growth is heavily impacted by genetics and overall health in addition to use; and any environment or actions that impact muscle growth are also going to impact skeletal structure - just at a slower pace. Obviously, chewing hard foods affects jaw muscles. Ergo, it's also going to impact skeletal development.
