I'd like to read the full paper. But It is not available online.

The spike glycoprotein of the new coronavirus 2019-nCoV contains a furin-like cleavage site absent in CoV of the same clade

 

The above paper is referred by the following article. I am skeptical to any theory at this point.

CONFIRMED: CoVid-19 coronavirus found to contain unique “gain-of-function” property “for efficient spreading in the human population” … exact quote from science paper just published in Antiviral Research

(Natural News) We now have bombshell, smoking gun evidence that the CoVid-19 “Wuhan” coronavirus was specifically engineered as an offensive biological warfare weapon, designed to target to exterminate human beings.

A new study published in the peer-reviewed journal Antiviral Research (Vol. 16, April 2020) is entitled, “The spike glycoprotein of the new coronavirus 2019-nCoV contains a furin-like cleavage site absent in CoV of the same clade.”

It reveals that the CoVid-19 coronavirus contains unique features that allow it to function as a more efficient weapon system for human-to-human transmission, which helps explain why the virus has been impossible to contain (even under “quarantine” conditions, which have universally failed in China, Japan, Korea and elsewhere).

As the science authors of the paper explain in the full text, “This furin-like cleavage site… may provide a gain-of-function to the 2019-nCoV for efficient spreading in the human population.” (Emphasis added)

Further, the science paper finds that there is no known viral ancestry to the CoVid-19 coronavirus, meaning it did not evolve from nature. It was engineered, and the science paper authors also state that the virus contains elements from MERS, stating, “Before the emergence of the 2019-nCoV, this important feature was not observed in the lineage b of betacoronaviruses.”
