文献明天介绍,很有意思的是,男性颅骨和女性颅骨特征反应的人群混合程度并不一样,呵呵,女性几乎与新石器时代的原著人群类聚,而男性则可以看到外来成分的影响,谁说颅骨就不能折射父系和母系遗传的不同?:lol  突然,联想到远东的数据或许也是如此,我之前就提过,远东华北组人群,女性的阔面比例明显比男性高。

Population history and substructure of Anatolia and Turkey as evidenced by craniofacial diversity.


Anatolia, the Asian segment of Turkey, is an area of evolutionary importance for human groups who used this corridor as a bridge for migration between the Caucasus, Western Asia and Europe since Lower Paleolithic times. Historically, Anatolia has been occupied by diverse civilizations, including the Byzantine and Ottoman Empires. This study is an attempt to understand Turkish population substructure and history by examining craniofacial diversity through several temporal periods framed within a population genetic model. If the region of Anatolia has been used as a migratory corridor for peoples spanning disparate geographic areas (Balkans, Central Asia, and East Asia), then gradual craniofacial change is expected due to these migrations coupled with extensive admixture. Studies using mtDNA indicate a pre-Neolithic expansion resulting in extensive migration, while Y chromosome studies reveal haplogroup clustering and gene flow from the Caucus with less admixture from Central and East Asia. Overall, our results indicate minimal Turkish population substructure. When crania were separated into sex, our results are consistent with uniparental marker population history. Female crania show a distinctness with modern groups and are actually more similar to Neolithic European and Near Eastern populations. This would indicate a relatively stable female population in Anatolia since Neolithic times. Male crania are more heterogeneous and cluster within a larger geographic zone of Eurasia and the Near East consistent with greater male migration. There is little support for admixture from Central or East Asian groups. These results support the hypothesis for a Turkic language displacement with insignificant genetic exchange.
