Where Do New Viruses Come From? 4.5

While the origin of the new Coronavirus is not yet known, we do know where new viruses normally come from. Hint: Darwin's theory of evolution is full of clues!

In this animation you will get a crash course in virology. You'll learn how viruses differ from other microbes, why most viruses can only infect one type of host organism, and how viruses evolve to infect new hosts.

How we stopped the SARS coronavirus

Pangolins as a potential intermediate host

Corrections:
In the animation I call the virus COVID-19, but this is technically incorrect. COVID-19 is the name of the disease it causes. The virus itself is called SARS CoV 2. Thanks to YouTube user "Charles Starbuck" for pointing out the error.

Strange? I always believed that viruses were made in a super high tech lab founded by the elite that had 5g antennas were bats rested back in the 1300s.
