原標(biāo)題：科學(xué)家們?nèi)绾文艽_認(rèn)新冠病毒并非實(shí)驗(yàn)室產(chǎn)物,？

從疫情爆發(fā)至今，雖然世界各地的科學(xué)家們都反復(fù)強(qiáng)調(diào)這種初次被發(fā)現(xiàn)的病毒來(lái)源于自然界,，但是“新冠病毒是實(shí)驗(yàn)室產(chǎn)物”的陰謀論依然無(wú)休無(wú)止,。

那么，科學(xué)家們到底是如何知道病毒并非來(lái)自實(shí)驗(yàn)室,，而是起源于某種動(dòng)物的呢,？

威斯敏斯特大學(xué)一位寄生蟲(chóng)學(xué)與醫(yī)學(xué)微生物學(xué)講師，Polly Hayes,，本周發(fā)表的一篇文章,，引用多項(xiàng)研究對(duì)這個(gè)問(wèn)題作出了解釋。

The conspiracy theory that the novel coronavirus was created in a lab has been circulating since the beginning of the COVID-19 outbreak,， although scientists from different countries have refuted it over and again and stressed the natural origin of the virus,。

So how exactly do scientists know the virus SARS-CoV-2 originated from an animal,， most likely a bat， and was not lab-made,？

Polly Hayes,， a lecturer in Parasitology and Medical Microbiology at the University of Westminster， explained the question in an article published on British website The Conversation earlier this week,， citing multiple studies,。

基因物質(zhì)里并沒(méi)有人為操縱的跡象

No signs of manipulation in the genetic material of SARS-CoV-2

Hayes指出，如果病毒來(lái)自實(shí)驗(yàn)室里的基因工程,，那么它的基因序列數(shù)據(jù)一定存在人為操縱的跡象,。

但是，新冠病毒的基因序列已被全世界的科學(xué)家公開(kāi)分享了數(shù)千次,，而且從未發(fā)現(xiàn)過(guò)這樣的證據(jù),。

Hayes pointed out that if the virus had been genetically engineered in a lab， there would be signs of manipulation in the genome data,。

This would include evidence of an existing viral sequence as the backbone for the new virus,， and obvious targeted inserted （or deleted） genetic elements。

But the genetic sequence of SARS-CoV-2 has been publicly shared thousands of times by scientists all over the world,， and no such evidence has ever been found,。
