>"Hard to find" is not the same as "vanished".

Which is strange for a virus as you stated. "found to have jumped to quite a few other animals; cats, dogs, hippos, anteaters, manatees; it's clearly not picky". So why is it so hard to find the virus that spilled over into humans, this virus would have been better adapted towards their own species and would have not been replaced by the human variants. We find SARS circulating in animals all the time, but they all descend from the human variant.

It is the Immaculate Infection!

It looks like you've been posting about this single flamewar topic and almost nothing else for years now. That's not ok - we don't allow single purpose accounts on HN, and ban them when they show up, because pre-existing agendas aren't compatible with the curiosity we're trying to optimize for.

I'm not going to ban you right now because if I scroll back far enough, your account used to be more in keeping with the intended spirit of the site. But please go back to that so we won't have to.

Or, more mundanely, whatever mutation allowed it to be not-very-picky might be recent. The Black Death likely came about when Yersinia pestis went aerosolized, for example, despite the bacteria probably being around at least back to Roman times.
