O-okay.

Anyway, I'm not the OP but it's worth noting that I've basically never seen other animals with fucked up teeth/dental arches like humans get on the regular. Also looking at skeles from some time ago would probably be instructive also.

More because diets change significantly. Also, that was directly after WWII so food probably wasn't in the optimum quantities or of the right quality

>directly after WWII
1939 is like the start of WWII, and it was published then so likely the research was conducted prior. Also fairly sure people today get plenty of retarded tooth problems with ample food.

I knew that, I-I was just pretending

The incidence of retarded tooth problems is lower now

So what do you think causes this? Sugars?

>The incidence of retarded tooth problems is lower now
Possible, though many people make use of dentistry and dental hygiene which could mask the problem; at any rate if incidence was still lower in these primitive people that's pretty funny given how much effort we put into dental health.

>So what do you think causes this? Sugars?
The hypothesis I believe was that lack of physical strain from chewing tough foodstuffs, much like how a baby born in space would probably have a poorly developed skeleton.

not a matter of nutrition, it's the density of the diet

70+% of america/uk have some degree of malocclusion
