overbite

It is suggested that those with an overbite we able to survive/mate better in the presence utensils than those without an overbite?

The overbite is the direct result of humans developing/using eating utensils (this fact may have actually been from a recent HN front page post).

And is an overbite really such a disadvantage that it would select you right out of the gene pool?

Why can't the opposite be true; those without an overbite are able to survive/mate better in the absence of utensils?

So even if utensils over one's life caused a overbite, it would not be transmitted via genetics to one's offspring.

This is not about a genetic, evolutionary change from an underbite/edge-to-edge mastication back to overbite/up-down mastication.

Notice Neandethal-era skull has a perfect bite and the modern human skull has an overbite.

South Asians also have overbite, even in regions where people still eat with their hands.

What would an overbite even theoretically have to do with the ability to pronounce [s]?

Presumably there's jawline issues (overbite) and the teeth aren't properly aligned, besides the hygiene.

I still have overbite but I'm not sure it's really a problem especially compared with the risks of surgery.

Then the modern presence of overbite is easily explained as genetic drift.

I overheard some guy at a happy hour bragging about how easily he was able to automate his overbite by using a technique called "4 Handed Dentristry".

In hindsight, I really didn't mean to emphatically state: "The overbite is the direct result of humans developing/using eating utensils" I just meant to mention the theory and that I thought I first learned about the theory on the HN front page, but perhaps I read about it elsewhere anyway.

Overbite, and hence one of the main reasons for lower crowding, only came about once we invented cutlery.

Overbite has a list of plugins and clients that work on most platforms.
