The NIH Director's Blog has an interesting read. Suggest looking at it. He states:
The researchers went on to analyze genomic data related to the
overall molecular structure, or backbone, of the new coronavirus. Their
analysis showed that the backbone of the new coronavirus’s genome most
closely resembles that of a bat coronavirus discovered after the
COVID-19 pandemic began. However, the region that binds ACE2 resembles a
novel virus found in pangolins, a strange-looking animal sometimes
called a scaly anteater. This provides additional evidence that the
coronavirus that causes COVID-19 almost certainly originated in nature.
If the new coronavirus had been manufactured in a lab, scientists most
likely would have used the backbones of coronaviruses already known to
cause serious diseases in humans. So, what is the natural origin of the novel coronavirus responsible
for the COVID-19 pandemic? The researchers don’t yet have a precise
answer. But they do offer two possible scenarios. In the first scenario, as the new coronavirus evolved in its natural
hosts, possibly bats or pangolins, its spike proteins mutated to bind to
molecules similar in structure to the human ACE2 protein, thereby
enabling it to infect human cells. This scenario seems to fit other
recent outbreaks of coronavirus-caused disease in humans, such as SARS,
which arose from cat-like civets; and Middle East respiratory syndrome
(MERS), which arose from camels. The second scenario is that the new coronavirus crossed from animals
into humans before it became capable of causing human disease. Then, as a
result of gradual evolutionary changes over years or perhaps decades,
the virus eventually gained the ability to spread from human-to-human
and cause serious, often life-threatening disease.
The concern of many is that it was a man made variant with a gain of function insert.
