The first COVIT 19
Mutations of four spike proteins from bats.
Two are derived from bats,
One is similar to the AIDS virus but half the length,
The remaining one is unknown.
It would not be possible to prove whether the spiked protein was genetically engineered.
The missing ring, an intermediate host, is probably not found.
Perhaps they used experimental animals such as mice and pigs that have human receptors, or humans themselves.
The intermediate host may have been a person with a specifically high affinity for standard deviation.
The singularity of the deviation may have repeatedly changed to S type and L type.
The final evolution from Lucy in Yunnan to the Delta type.
Sure someone pulled the trigger.
Could a scientist have stopped it somewhere?
