Here's a lesson for libtards: Viruses mutate. Like crazy. In fact, for viruses, mutation is their only means of long-term survival. Viruses that don't mutate well extinct themselves. So, yes, viruses CAN mutate to infect different species or types of animals. Bird to mammal, etc. The natural progression for most viruses is to mutate from being deadly to its host to being much less deadly to its host; and from being less communicable to being more communicable. When, say, a bird flu mutates to infect humans, its first human victims may get very sick and maybe die. But, soon enough, new mutants of the virus that are less deadly will overtake the more deadly ones . . . because viruses spread more readily when their hosts stay living. Understanding that, the whole COVID19 fiasco shows conclusively that the virus was artificially human-engineered to be both fairly lethal AND easily communicated--an unnatural progression. But, once released, it quickly succumbed to natural forces, and, over a relatively short time, became even more communicable but much less lethal. As for bird flu, I've endured talk about it infecting humans for over 40 years. There was a panic about a bird flu pandemic infecting humans back when I was in the livestock business in the 1970's. It's nothing "new."
You are aware that the human genome has bits of virus sequences in it, that viruses have been changing us as long as humans have been around. Viruses are one form of mutation, as well as radiation that allows any species to change, to mutate, to adapt to changing environments. Just think, if Covid might end up being a positive for the human genome in some fashion. Or polio, or Ebola, or Zika, or flu. Or the cold. Remember too that viruses have been proved to cause cancer, another indication of their ability to change DNA.
