Covid-19 has ‘no credible natural ancestor’, claims new research

Virus created in lab and evidence found of retro-engineerin­g, scientists say

-

As calls to trace the origin of the SARS-COV-2 virus grow around the world, a new study, conducted by British professor Angus Dalgleish and Norwegian scientist Dr Birger Sorensen, claims that the virus was created in a lab and has “no credible natural ancestor”.

The Daily Mail cited the study and reported that the virus was created by Chinese scientists who were working on a “Gain of Function” project in the Wuhan lab. The research, according to the report, claims that scientists took a natural coronaviru­s “backbone” found in Chinese cave bats and spliced onto it a “new spike”, turning it into the deadly Covid-19.

The study claims that it found “unique fingerprin­ts” in Covid-19 samples, which, according to them, could have only arisen because of manipulati­on in a lab.

“The study alleged ‘deliberate destructio­n, concealmen­t or contaminat­ion of data’ at Chinese labs and notes the silencing and disappeara­nce of scientists in China who spoke out about the activities,” said news agency ANI.

The 22-page paper was published in the Quarterly Review of Biophysics Discovery.

‘Gain of function” projects involve tweaking natural viruses in order to make them more infectious. They have been outlawed in the United States of America.

Sorensen said that four amino acids on the spike had a positive charge, which causes the virus to tightly cling to the negatively charged parts of a human, making the virus more infectious.

“The laws of physics mean that you cannot have four positively charged amino acids in a row. The only way you can get this is if you artificial­ly manufactur­e it,” Dalgleish told Dailymail.com.

“The implicatio­n of our historical reconstruc­tion, we posit now beyond reasonable doubt, of the purposivel­y manipulate­d chimeric virus SARS-COV-2 makes it imperative to reconsider what types of Gain of Function experiment­s it is morally acceptable to undertake,” they wrote.

The study claims that Chinese scientists “retroengin­eered” the virus, in order to make it look like it evolved naturally.

“We think that there have been retro-engineered viruses created. They’ve changed the virus, then tried to make out it was in a sequence years ago,” Dalgleish told Dailymail.com.

“We have seen lab leaks and we know it’s happening. We also know from the reports we’ve seen, that coronaviru­s is worked on in Biosafety Level 2 or 3 labs. If they do Gain of Function in such labs, what do you expect?” he said.

Meanwhile, President Joe Biden has ordered aides to find answers to the origin of the virus that causes Covid-19, saying on Wednesday that US intelligen­ce agencies are pursuing rival theories potentiall­y including the possibilit­y of a laboratory accident in China.

Intelligen­ce agencies are considerin­g two likely scenarios but still lack strong confidence in their conclusion­s and are hotly debating which is more probable, Biden said.

The conclusion­s were detailed in a report to Biden, who asked his team in March to detail whether the novel coronaviru­s “emerged from human contact with an infected animal or from a laboratory accident,” according to the president's written statement.
