The Novel Coronavirus that has caused the pandemic is a product of natural evolution not artificial made a study says by ending rumours that virus have been made in a lab.

Nature medicine journal published that researchers analysed the genome sequence data of SARS CoV-92, Coronavirus. The researchers including researchers from The scripps research institute said they didn't find any prove that the virus was engineered or made in any laboratory.

Kristian Anderson from the Scrips Research Institute said , they have compared the genome sequence data of Coronavirus strains, and they conclude that SARS CoV-92 originated through nature.

They also made it clear that sequence data has already shown that the number of COVID19 cases have been increasing because of human to human interaction after a single introduction of the virus to human population.

The researchers traced the evolution and origin of SARS-CoV-2 by pivoting on the tell-tale feature of it, using sequence data.

To trace it researchers said they examined the genetic template for spike proteins -armatures on the outside of the Coronavirus that it uses it to penetrate into the outer wall of the human cells.

The study focused on mainly two major feature of the spike protein -the RBD , one kind of grappling hook which grips on the host cell and the Cleaver site , a kind of molecular opener which allows virus to crack or open to enter the host cell.

According to research the RBD part of the SARS Cov2 spike proteins which has evolved so effectively to target human cells outside layer called as ACE2 .

The novel Coronavirus's spike protein was very effective at binding human cells that the scientists said it was the product of natural selection not any kind of genetic engineering.

They also said if it was engineered as a pathogen it must have been constructed through a backbone of virus capable of causing illness. But SARS CoV2's backbone is different than that of other Coronavirus's , and mostly resembled viruses found in pangolins and bats .
