National Geographic's Genographic Project uses the term 'Coastal Clan' to describe the initial human groups of Y-DNA haplogroup C who expanded eastwards out from Africa along the coastal route around 50 kybp. Roger Blench discusses the theory in relation to language families.〔http://www.rogerblench.info/Archaeology%20data/World/Manila%202006/Indian%20Ocean%20settlement%20paper%202006.pdf The Pleistocene settlement of the rim of the Indian Ocean〕 Many centuries later, the ancestors of the Malagasy people are believed to have migrated coast-wise along the same route, but in the opposite direction (viz. westward along the shores of the Indian Ocean). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coastal migration」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
