Shape and size changes in the human skull: the effect of dietary transitions
We evaluate different skull subregions to detect if changes in food consistency have an effect on size and shape variation. Three population economic transitions and three non-transitional populations were analyzed. Ninety 3D landmark coordinates were digitized in a sample of 459 skulls and analyzed...

I28-R145-10668_oai2022-09-23 Paschetta, Carolina González-José, Rolando 2022-05-19 We evaluate different skull subregions to detect if changes in food consistency have an effect on size and shape variation. Three population economic transitions and three non-transitional populations were analyzed. Ninety 3D landmark coordinates were digitized in a sample of 459 skulls and analyzed using geometric morphometry. Additionally, the bite force was estimated for each group. Our results indicate size differences between transitions and cranial regions. The shape changes are concentrated in the temporal and masseter muscles insertion, which show an anteroposterior lengthening in the hard diet groups in relation to the soft diet groups. Other important changes occur in the zygomatic arch, which is wider in the hard diet groups. The bite force is overall higher in the groups representing the toughest diets. Evaluamos diferentes subregiones del cráneo para detectar si los cambios en la consistencia de los alimentos producen un efecto en la variación de tamaño y forma. Se analizaron tres transiciones económicas poblacionales y tres poblaciones no transicionales. Se digitalizaron noventa coordenadas de landmarks en 3D en una muestra de 459 cráneos y se analizaron mediante morfometría geométrica. Adicionalmente se estimo la fuerza de mordida para cada grupo. Nuestros resultados indican diferencias de tamaño entre las transiciones y las regiones craneales. Los cambios de forma se concentran en la inserción de los músculos temporal y masetero, que muestran un alargamiento anteroposterior en los grupos de dieta dura en relación con los grupos de dieta blanda. Otros cambios importantes ocurren en el arco cigomático, que es más ancho en los grupos de dieta dura. La fuerza de mordida en general es mayor en los grupos que representan las dietas más duras. application/pdf text/html http://revistascientificas.filo.uba.ar/index.php/runa/article/view/10668 10.34096/runa.v43i2.10668 spa Instituto de Ciencias Antropológicas, Facultad de Filosofía y Letras, UBA http://revistascientificas.filo.uba.ar/index.php/runa/article/view/10668/10255 http://revistascientificas.filo.uba.ar/index.php/runa/article/view/10668/10383 Derechos de autor 2022 Carolina Paschetta https://creativecommons.org/licenses/by/4.0 RUNA, archivo para las ciencias del hombre; Vol. 43 Núm. 2 (2022): Dossier: Antropología Biológica; 87-116 RUNA, archivo para las ciencias del hombre; Vol 43 No 2 (2022): Dossier: Antropología Biológica; 87-116 RUNA, archivo para las ciencias del hombre; v. 43 n. 2 (2022): Dossier: Antropología Biológica; 87-116 1851-9628 0325-1217 Geometric morphometry; Size and shape variation; Economic transitions; Skull; Biomechanics.
