Did pangolins spread the China coronavirus to people? Genetic sequences of viruses isolated from the scaly animals are 99% similar to that of the circulating virus — but the work is yet to be formally published. The identity of the animal source of the coronavirus, named nCoV-2019, has been one of the key questions that researchers have been racing to answer . Coronaviruses are known to circulate in mammals and birds, and scientists have already suggested that nCoV-2019 originally came from bats, a proposal based on the similarity of its genetic sequence to those of other known coronaviruses. But the virus was probably transmitted to humans by another animal. The coronavirus that caused severe acute respiratory syndrome, or SARS, spread from bats to civet cats to humans .
他是业界科研人士，华盛顿大学/Fred Hutch的。
可以查到他在学校的网站，发表文章， 教育背景，研究领域
（相比之下，网络推进阴谋论的所谓”专业人士“一般背景模糊）

这位是做病毒的，而且相当关注新冠。他的推特经常跟踪最新研究进展。他明确说新冠病毒的变异与natural evolution 一致。
最新的evolution tree， 实际上因为很多国家都有病例了，基因测序跟进很快。可以看到这些的同源性。
业界研究热点是从蝙蝠--中间宿主--人 的中间宿主究竟是什么动物。
比如这篇Nature 快讯说国内有研究机构认为穿山甲可能是，穿山甲分离出的冠状病毒，与新冠有很大相似性。但是目前不知道这个病毒基因序列究竟怎样，文章还没有正式发表，所以还不能肯定。bottom line, 这些信息公开透明，而且可以说很多做病毒研究的人都盯着，但是主流共识是 蝙蝠---中间宿主（另外一种野生动物）--人。

现在要问的是，这种能感染人的病毒是怎么来的？为什么现在可以识别人？
evolution tree 说明 新冠与原生宿主是蝙蝠的一些其他冠状病毒同源，可能通过某动物中间宿主的变异，感染到人。
SARS 也类似。
也许你有宣传材料，在这里有同事，而且人数还不少。而且您是不是天天在这守着啊，泼脏水手段娴熟，上来就是转移话题，人身攻击。
我在本版不认识任何人，也没兴趣认识。只不过看不过这里阴谋论泛滥，给点正常的，理性的材料来源而已。
这人专业好歹比那个印度码工，反疫苗民科科学家和不知道职业的武博士更靠谱。至于石正丽的论文，也有生物mm在隔壁详解。当然你和你同事们肯定看不懂那个mm的科普了
