Could it be more of a genetic thing to have straight teeth or are there outside factors involved too? Not to mention having crooked teeth can cause so many issues but it’s common.

I heard a podcast on this. An orthodontist was watching a documentary and noticed that the teeth on skulls in an ossuary were rarely crooked. His hypothesis is that our ancestors ate tougher foods earlier, expanding the palate naturally before it solidifies allowing all teeth to align almost perfectly. Even allowing space for the wisdom teeth. Due to a softer modern diet, that palate doesn’t expand as much causing crowding and additional crowding from impacted wisdom teeth. He went further back through the anthropological fossil record and solidified his hypothesis.
He posited that it’s not discussed because the orthodontics industry is a hugely profitable industry.
