As the search for the origin of Covid-19 continues, biologists have now found evidence suggesting the virus was "pre-adapted to human transmission", reported by the Daily Mail news.

The study raises the possibility that the virus may have escaped from a lab in Wuhan, which was known to be studying coronavirus like diseases in bats.

Biologists Yujia Alina Chan and Benjamin Deverman from the Broad Institute carried out the new research alongside Shing Hei Zhan from the University of British Columbia.

For their study, they compared the genetic samples from Covid-19 patients with those from the coronavirus of the 2002-04 SARS epidemic - which was also transmitted from bats to humans. They wrote that they were surprised to find that the new coronavirus "resembles SARS-CoV in the late phase of the 2003 epidemic".

But this similarity raised their suspicions, as while SARS-CoV had evolved as it spread across the world, the new coronavirus arrived in a "highly infectious" form that seemed "pre-adapted to human transmission".

The scientists also genetically examined four samples containing the virus from the animal market to those taken from a patient in Wuhan in December. In doing so, they found the two were "99.9 percent identical", and stated this pointed towards the theory that "Sars-CoV-2 had been imported into the market by humans".

But the suggestion that the coronavirus may have originated in a lab has also been challenged before by scientists, with the WHO calling the theory "speculative".

China's Centre for Disease Control and Prevention still says on its website: "The virus was successfully isolated from positive environmental specimens, suggesting that the virus originated from wild animals sold in the South China Seafood Market."

Well,a very sad news indeed. The cost of biological experiments ,of just one of them,and the world is paying such a heavy price.

Why these types of studies are carried on without any preventive measures and studies are conducted without any broad spectrum antivirals available? It' s like MASS SUICIDE AND MURDERS
