According to a new research, the advent of farming, especially dairy products, had a significant effect on the shape of human skulls.
According to the study published in the journal Proceedings of the National Academy of Sciences, the effect of agriculture on skull morphology was greatest in populations consuming the softest food – cheese.
A worldwide collection of 559 crania and 534 lower jaws from more than two dozen pre-industrial populations were used to model the influence of diet on the shape, form, and size of the human skull during the transition to agriculture.Katz, with Professor Tim Weaver and statistician Mark Grote from
Katz, with Professor Tim Weaver and statistician Mark Grote from the University of California, found modest changes in skull morphology for groups that consumed cereals, dairy, or both cereals and dairy.
He said that the main differences between forager and farmer skulls are where we would expect to find them, and change in ways we might expect them to if chewing demands decreased in farming groups
According to the study, the largest changes in skull morphology were observed in groups consuming dairy products.
