Dusty belongs to mtDNA Haplogroup B2, one of four major haplogroups that’s prevalent among Native Americans. Haplogroup B2 is unusual amongst Native American haplogroups because there is very little evidence that they crossed the land bridge between Russia and Alaska.
Most haplogroups spread from the north to the south, as you would expect from a land bridge crossing. Strangely, mtDNA haplogroup B2 spread from the South to the North, and it is most commonly found in Peru. This evidence suggests that Crawford’s ancestors crossed the Pacific Ocean sometime during the last Ice Age. This is bolstered by the fact that many native Pacific Islanders only belong to mtDNA haplogroup B2. Additionally, their closest mtDNA haplogroup, B4b1, is found in Southeast Asia.

扩散一直都有。南岛人还种植红薯。
末次冰盛期颇有可能发展出过原始农业。

C的印第安人在北美
C—M130是棕种人基因,海洋居民,C—M130走的路线大概就是沿着海岸出发,从阿拉伯半岛—伊朗—印度—中南半岛,此后,这批C—M130的子孙分为两支系,NO.1支系向北进入西伯利亚,并最终进入了北美地区;NO.2支系向南进入澳大利亚,并扩散到整个太平洋诸岛。
今天C—M130的后代主要分布在印度南部、北亚东部、日本、北美西部、澳大利亚、太平洋诸岛。在东亚地区,外蒙地区比例非常高,达到58%,还有哈萨克人、吉尔吉斯人、布里亚特人、比例都在60%以上,这些人群的类型(包括北美地区)都是C3—M217;M130的其他类型还有,日本的阿伊努人90%以上是C1—M8,另外,现代日本人(6.5%)、朝鲜人、满州人、阿穆尔人中,也有一定数量的C1。C2—M38,主要分布在澳大利亚和太平洋诸岛屿,C4、C5主要分布在南印度地区,在当地民族中能达到20%。在汉族人中几乎没有C-M130基因的分布。

工具机谈智商, 犹如妓女谈贞操, 哪壶不开提哪壶
呼叫鸡谈造谣, 犹如站街女谈卖淫, 那是行家里手
