The findings are published in the journal Proceedings of the National Academy of Sciences (PNAS).
Variant A, most closely related to the virus found in both bats and pangolins, is described as the root of the outbreak by researchers. Type B is derived from A, separated by two mutations, then C is in turn a ‘daughter’ of B, the study suggests.
The phylogenetic network methods used by researchers – which looks at evolutionary relationships among biological entities – allowed the visualisation of hundreds of evolutionary trees simultaneously in one simplegraph.

这种时候建议LZ最好去读一下PNAS发表的原文，News通常断章取义。 论文里：There are two subclusters of A which are distinguished by the synonymous mutation T29095C. In the T-allele subcluster, four Chinese individuals (from the southern coastal Chinese province of Guangdong) carry the ancestral genome, while three Japanese and two American patients differ from it by a number of mutations. These American patients are reported to have had a history of residence in the presumed source of the outbreak in Wuhan. The C-allele subcluster sports relatively long mutational branches and includes five individuals from Wuhan, two of which are represented in the ancestral node, and eight other East Asians from China and adjacent countries. It is noteworthy that nearly half (15/33) of the types in this subcluster, however, are found outside East Asia, mainly in the United States and Australia. 给你翻译一下： A型有两个亚簇，由同义突变T29095C来区分。在T等位基因亚簇中，4名中国患者（来自中国南部沿海省份广东）携带始祖基因组，而3名日本患者和2名美国患者的基因组和来自中国的相比出现一些突变。这些美国患者曾有武汉旅行史。 A型中的C等位基因亚簇则具有相对较长的突变分支，包括来自武汉的5名患者（其中2个属于始祖基因组），以及另外8个来自中国和邻近国家、地区的东亚地区患者。值得注意的是，C等位基因亚簇中近一半（15/33）的类型是在东亚以外的地区发现的，主要在美国和澳大利亚。

以蝙蝠和穿山甲提取的病毒为基点来分析，Type A是爆发的根源。中国流行的Type B是A的衍生，有两次变异，C是B的子代。
