So - how did this virus spread through the population? 20 kyrs ago people didn't live in cities but in small bands of a few dozen people. It's easy to see how an epidemic might spread through a village but how would it move between isolated groups?

#12Look at the infection/death rate in Southeast Asia. It strongly suggests past community transmissions of past coronaviruses.

#13> The finding could have dire implications for the Covid-19 pandemic if it’s not brought under control soon through vaccination. > “What is going on right now might be going on for generations and generations.” > Covid-19, SARS and MERS. Studies on each of these coronaviruses indicate that they jumped into our species from bats or other mammals. Hard to take seriously an article having such an obvious agenda.
Agenda of science - how dare they talk about vaccines or viruses jumping between spices.
I read on Facebook while I was pooping, that vaccines are evil and don't work, and viruses only exists in our world, because people are engineering them! That's the truth, that has no agenda behind it! /s

I’m not an expert but scientists have found that coronaviruses are aerosolized. So i think the process of aerosolization probably played a part.

Groups interacted with each other. A large reason that humans are found more or less everywhere on the planet was pressure from interacting with other humans.

Maybe the virus was not a pandemic 20k years ago. Small tribes that carried genes that are resistant to the coronaviruses spread later on as they established larger communities/cities.

Human civilization was probably much more developed back then than 'experts' believe. Look at a satellite map, most of that light blue you see was land during that time. The East China sea was mostly land. You think people, like the majority of people, weren't living there?
Just look at the gobekli tepe story.

Yes, people seem to miss this. There are several mild endemic coronavirus diseases in humans, usually called "common cold" along with many others.

Yes. They've also caused three major epidemics in the past two decades - there's no reason they shouldn't have emerged historically from time to time.
