Dental morphology of the Dawenkou Neolithic population in North China: implications for the origin and distribution of Sinodonty

Correlations between deciduous and permanent tooth morphology in a European American sample

“…V V C 2007 Many normally occurring occlusal and tooth crown morphological variables have been identified and quantified in human populations in both the deciduous and permanent dentitions (Dahlberg, 1951;Jørgensen, 1956;Hanihara, 1960Hanihara, , 1967Hanihara, , 1969Turner, 1990;Zubov, 1992;Irish, 1997). Anthropologists use expression frequencies of morphological characteristics of both the permanent (Scott, 1980;Kieser and Preston, 1981;Turner, 1990;Hanihara, 1992;Guatelli-Steinberg et al, 2001;Manabe et al, 2003;Irish, 2006) and deciduous teeth (Hanihara, 1960(Hanihara, , 1967(Hanihara, , 1969Grine, 1986;Kitagawa et al, 1995;Sciulli, 1998;Lease and Sciulli, 2005;Lukacs and Walimbe, 2005) to examine relationships between populations. This is possible because expression of these traits is genetically modulated (Garn et al, 1963(Garn et al, , 1966aBader, 1965;Sofaer, 1970;Goose and Lee, 1971;Biggerstaff, 1975;Corruccini et al, 1986;Scott and Turner, 1997).…”

Dental and oral nonmetric traits in a Coimbra reference sample: testing intrasample chronological and spatial variation

“…The MMD results in Table 6 reflect biodistances lower than, or similar to, significant MMDs of Christian-era Nubians (Irish 2005), Neolithic to Roman Egyptians (Irish 2006), North American Southwest indigenous tribes (Scott and Dahlberg 1982), early Christians from a Byzantine monastery and Near East samples (Ullinger 2002), Late Bronze-to-Early Iron Age transition southern Levantines (Ullinger et al 2005), circum-Caribbean samples (Coppa et al 2008), and Maharashtra Indians (Lukacs et al 1998), which are mostly biologically homogeneous samples. The MMD results reported by Manabe et al (2003) for a much wider and diverse region, Asia, show higher-occasionally much higherbiodistances. The low biodistances found in the present analysis underline the biological continuum found for this mostly Portuguese sample from Coimbra and of the late modern/early contemporary Portuguese population as a whole.…”

Population history of the northern and central Nansei Islands (Ryukyu island arc) based on dental morphological variations: gene flow from North Kyushu to Nansei Islands

“…During the analysis of variations in 36 Asian-derived populations, the Thai tribe (Manabe et al, 1997), the Northeast Chinese (Manabe, personal data), the Neolithic Northern Chinese (Manabe et al, 2003b), the Taiwan Yami tribe (Manabe, 1989), the Taiwan Bunun tribe (Manabe et al, 1991), the Taiwan Ami tribe , the preInca Peruvian , and 17 other East-Asian populations (Turner, 1987) were compared with the two modern Nansei islander groups in this study. Nichol and Turner (1986) discussed the interobserver error and suggested that when scoring is performed by different observers, sample comparisons are possible at various levels of confidence.…”

“…Nichol and Turner (1986) discussed the interobserver error and suggested that when scoring is performed by different observers, sample comparisons are possible at various levels of confidence. We have previously examined the positions of typical sinodonty and typical sundadonty in the MDS in order to observe interobserver concordance (Manabe et al, 2003b). We concluded that it was possible to analyze both Turner's and Manabe's data because of the approximate agreement between these two sets of observations.…”
