The advent of agriculture is associated w~h the reduction of tooth size, crowding, increases in caries, and increased occurrence of periodontal disease. Archaeological evidence suggests that humans adopted new ways of processing food during the Neolithic which included the use of grinding stones and cooking in ceramic vessels (Larsen 2006; Meller et al. 2009). This is supported in Neolithic samples by a pattern of decreased skull size and shape and dental microwear evidence (Larsen 2006; Sardi et al. 2004). Bone responds to high amounts of physical activity and stress by increasing in mass (Larsen 2006: 16). Paleolithic hunter-gatherers likely had larger skulls than Neolithic peoples due to their more mobile and active lifestyle (Sardi et al. 2004). "It is accepted that masticatory forces regulate craniofacial growth and the stress is mainly due to the food consistency that causes variations in the mastication movement" (Sardi et al. 2004: 141). This means that facial structures are suited to individual chewing needs. When new preparation and processing methods were introduced, foods became softer and easier to chew. Over time this change in masticatory function contributed to an overall "gracilization" of the human skull and resulted in a smaller human face with reduced jaws and teeth (Larsen 1991, 2006; Sardi et al. 2004). Reduction of the face negatively affected human oral health because human teeth did not reduce proportionately to the jaw and crowding resulted (Larsen 2006).

This must be why people have trouble with their so called “Wisdom tooth”. I read that humans evolved to have this tooth specifically to eat meat.

There are a lot of weird conjectures about wisdom teeth floating around the internet. With wisdom teeth included, humans have the same number of teeth as most other apes and monkeys--i.e. it's a very old result of shared evolutionary history. Wisdom teeth erupt later than other teeth since the jaw basically is not big enough until the late teens/20s to accommodate them.

Indeed, smaller jaws cause problems accommodating an extra molar (I suspect more people will have problems on their lower jaw than upper jaw). Interestingly, some people don't grow wisdom teeth at all! I do not know if there have been any studies done on how this correlates to their jaw size.

The Neolithic Revolution fundamentally changed how humanity went about the business of surviving. With the rise of farming, humans no longer had to travel into inclement climates following the migration of animals, their former pervasive food source. Instead, fields of grain were cultivated, and, in turn, permanent settlements were created — civilization was established.

But while the social and economic effects of this revolution are apparent, other significant effects of switching to farming on our daily lives are more subtle. Among them is a minor change in our anatomy that allows us to make the "f" and "v" sounds.
...
F and V are labiodentals, which means to make their sounds you have to raise your lower lip to your top teeth. This is easy enough with a slight overbite, but if your teeth are closer to being even, as the skulls of our ancient ancestors suggest was once more common, the sounds become harder to make.

In a society where none of the food is softened by processing, most people are going to end up with no overbite at all by the time they're adults. In a society with softer, processed foods, such as grains, an overbite as an adult becomes possible and eventually the standard. This, more than anything, makes a language that uses labiodentals practical.

When looking at pics of certain groups I've noticed that vegetarian/vegan groups have similar skull shapes (oval/strawberry) for the most part. Same, with the opposition (wide, broad).

The headline is wrong, should be 7400:

www.ancient-origins.net/news-evolution-human-origins/4700-year-old-tooth-provides-insight-first-farmers-iberian-peninsula-020516

Eight thousand years ago, the first farmer groups from the Middle East crossed the area currently known as Turkey and entered into Europe before branching out to follow two different routes: one headed for Central Europe through the Danube, and the other for the Iberian Peninsula, following the path marked by the Mediterranean Sea. Some human groups in Europe implemented a new and revolutionary way of life, characteristic of the Neolithic period.

The Neolithic was a time that agriculture spread with unprecedented speed, causing fundamental changes in the lives of human beings, from hunters and gatherers to farmers. This fact in turn led to nomads becoming sedentary, settling in fixed locations and the creating the first residential villages. These settlements allowed the increase in population when there was a surplus of some products; they also led to the emergence rudimentary trade in the form of bartering.

The current study of the tooth found in the cave, Cova Bonica Vallirana, in Catalonia, has revealed information on one of the early European Neolithic farmers as well as showing us that the Neolithic farmers of Central Europe and the Mediterranean may have shared the same common origin.
...
A team of Spanish and Danish scientists have succeeded in sequencing the genome of one of the first farmers who lived in the Mediterranean area of ​​the Iberian Peninsula. The study of DNA from the tooth revealed that this ancient farmer was actually a woman; with light skin, dark hair, and brown eyes that lived about 7,400 years ago in what is now Catalonia.

This prehistoric woman, which we also know was lactose intolerant, belonged to the group of farmers who settled in the Mediterranean, developing their own culture, which has characteristically been called Ceramica Cardial ( Cardial pottery). This pottery is noted for the decorative incisions on the handcrafted pieces with the edges of bivalve shells, such as some pottery shards found in the same level as the tooth from the farmer woman found at Cova Bonica.

Lactose tolerance came later from Turanian diffusion.

I may actually have way more Neolithic genes expressing themselves than I originally gave myself credit for. Certainly do still have some Paleolithic traits. Interestingly, I can pin-point accurately which side of my family those came from. I have small teeth, and dentists have always told me I have a lot of free space in my mouth. I also have a gap in my upper front teeth.

I just ate oatmeal again for the first time in a long time, and remembered how much I absolutely fucken love oatmeal! I did corrupt it though with a little piece of butter....

"butter"

en.wikipedia.org/wiki/Butter#History

The ancient Greeks and Romans seemed to have considered butter a food fit more for the northern barbarians. A play by the Greek comic poet Anaxandrides refers to Thracians as boutyrophagoi, "butter-eaters".[17] In his Natural History, Pliny the Elder calls butter "the most delicate of food among barbarous nations"

en.wikipedia.org/wiki/Thracians

In Greek mythology, Thrax (by his name simply the quintessential Thracian) was regarded as one of the reputed sons of the god Ares.[5]
...
The origins of the Thracians remain obscure, in the absence of written historical records. Evidence of proto-Thracians in the prehistoric period depends on artifacts of material culture. Leo Klejn identifies proto-Thracians with the multi-cordoned ware culture that was pushed away from Ukraine by the advancing timber grave culture or Srubnaya.

en.wikipedia.org/wiki/Multi-cordoned_ware_culture

KMK tribes practiced herding and made widespread use of chariots.

"Ares, exceeding in strength, chariot-rider

We knew all this already, of course.

More correlations with Aryan teeth:

The unexpected finding showed slender faces correlated with a 25 per cent increase in the likeliness of a person favouring their left hand.
...
They also discovered that slender faces and jaws were associated with an overbite.
...
The researchers believe that the finding suggests that the genetics that shape facial features and tuberculosis susceptibility also linked to the increased the likelihood of being a leftie.
...
'The low body weight of this slender physique is still today recognised by the Centres for Disease Control and Prevention as a marker for TB susceptibility.'

In the early 20th century, slender individuals were described as 'ectomorphs', a term that persists in popular culture a reference to dieting and bodybuilding.

en.wikipedia.org/wiki/Tuberculosis_in_human_culture

The disease was for centuries associated with poetic and artistic qualities in its sufferers, and was known as "the romantic disease".[2]
...
A widespread belief was that tuberculosis assisted artistic talent, as witness the number of great artists who were affected. Physical mechanisms proposed for this effect included the slight fever and the toxaemia caused by the disease, which allegedly helped them to see life more clearly and to act decisively.

Without discounting the effects of tuberculosis itself on the mind, perhaps the ectomorphic physiology contributes both to susceptibility to tuberculosis and to artistic sense?
