Denticija Eskima Aleuta: morfologija krune i korijena
Svrha rada: Rad daje pregled morfologije krune i korijena u populaciji Eskima Aleuta s američkog Arktika. U tom kontekstu uspoređuju se dentalne varijacije Eskima Aleuta s blisko povezanim američkim Indijancima i daljnje povezanim Europljanima. Materijali i metode: Karakterizacija varijacije učestal...

Svrha rada: Rad daje pregled morfologije krune i korijena u populaciji Eskima Aleuta s američkog Arktika. U tom kontekstu uspoređuju se dentalne varijacije Eskima Aleuta s blisko povezanim američkim Indijancima i daljnje povezanim Europljanima. Materijali i metode: Karakterizacija varijacije učestalosti zubnih obilježja temelji se na opažanjima pokojnog Christyija G. Turnera II. i autora provedenima na približno 10 000 denticija. Šesnaest obilježja krune i pet obilježja korijena analizirano je prema smjernicama Dentoantropološkog sustava Državnoga sveučilišta u Arizoni. Rezultati: Od 21 razmatranog dentalnog obilježja samo su tri pokazala neznatne razlike između Eskima Aleuta, američkih Indijanaca i Europljana (peta kvržica na UM1, fisurni crtež na LM2, broj korijena na LM2). Za preostala je zabilježena drastična razlika između dviju populacija Novoga svijeta i Europljana. Iako općenito slični, Eskimi Aleuti i američki Indijanci razlikuju se u frekvencijama bilateralne meziopalatinalne rotacije (krilni Vpostav) na UI1, lopatastim i labijalno lopatastim sjekutićima, Carabellijevu svojstvu na UM1, tri kvržice na UM2, trokorijenskom UM2 i posebno trokorijenskom LM1. Zaključak: Razlike između triju skupina vjerojatno su rezultat genskoga odljeva i efekta osnivača, iako nedavno istraživanje alela EDAR V370A sugerira da neke dentalne varijable, poput lopatastog oblika i broja kvržica na donjim kutnjacima, mogu posredno odražavati prirodnu selekciju koja djeluje na druge varijable pod utjecajem toga alela. Objective of work: This paper provides an overview of crown and root morphology in Eskimo-Aleut populations of the American Arctic. For context, Eskimo-Aleut dental variation is compared to closely related American Indians and distantly related Europeans. Materials and methods: The characterization of dental trait frequency variation is based on observations made on approximately 10,000 dentitions scored by the late Christy G. Turner II and the author. Sixteen crown and five root traits were scored following the conventions outlined in the Arizona State University Dental Anthropology System. Results: Of the 21 dental traits considered, only three showed slight differences among Eskimo- Aleuts, American Indians, and Europeans (UM1 cusp 5, LM2 groove pattern, LM2 root number). For the remaining traits, there was typically a dramatic contrast between the two New World populations and Europeans. While generally similar, Eskimo-Aleuts and American Indians showed differences in UI1 winging, shoveling, and double shoveling, UM1 Carabelli trait, 2-cusped UM2, 3-rooted UM2, and especially 3-rooted LM1. Conclusion: The differences between the three groups are likely a product of genetic drift and founder effect although recent work on the EDAR V370A allele suggests some dental variables like shoveling and lower molar cusp number may indirectly reflect natural selection operating on other variables influenced by this allele. |
