True that “common cold” includes other virus types in addition to the coronavirus. I didn’t word my statement quite right, but meant every common cold caused by a coronavirus was once a novel coronavirus.
On the predator thing, have to agree to disagree. Viruses live and die, so are a type of living entity. And a predator is any living entity in nature that can and does kill another living entity to further it’s ability to live and reproduce. Choice only applies to human predators, most animal predators act out of involuntary instinct. And just because some predators hunt, doesn’t mean all predators do. After all, most of our prey we do not hunt but domesticate and essentially farm meat. Other great apes farm termites to eat. Even the lowly ants farm meat prey by having domesticated aphid farms.
Nature doesn’t really have any way to kill humans other than by infectious diseases. So they’re quite literally our primary predator. Teeny tiny but powerful.
