    There are fossils of viruses, of sorts, preserved in the DNA of the hosts that they’ve infected. Including you. This molecular fossil trail can help us understand where viruses came from, how they evolved and it can even help us tackle the biggest question of all: Are viruses alive?

              Is there any thought to the idea that maybe viruses are their own tree of life? A second biogenesis?

                              Viruses probably help living cells to evolve quickly.

                                  Can you create a virus? maybe by collecting dna/rna of different organisms and cover them with protein and place them in a capsule?

                                                Maybe I'm interpreting something wrong, but the virus first hypothesis doesn't make sense to me. Viruses need other cells to reproduce, so how could they have been first?

                                                              Mitochondria could be looked at as a precursor to bacteria but after viruses; Simply because the mitochondrion has it's own DNA Chromosome being however small that it is, and having it's own ribosomes to reproduce it's Genetic material, as well as producing proteins necessary for function?

He states: It's not alive because it can't reproduce on its own or control its internal environment. 😏 yeah, well I cant reproduce without a woman and i can't control the the weather or nature nor my outer or inner environments. I can't tell my stomic to digest faster or slower. But im alive. If you put me in space: I'll fu(king die, I'm quite sure of that. So if you take a virus out of a person and put it in a Petri dish. I'm sure it will die too. Im going to opt for it is alive.

                                                                                    What I'd like to know is on some very minute level is a virus a Sentient Being. Or just programed for simple tasks? I'm thinking programed. I can't see them hurting when they die. But what if they do 😳 we are at war people 😏

And if a virus can infect different species in the same lifetime than this means you dont need a commen ancester for this gene to be passed on to different species they could just have gotten the virus at the same time when this virus was active wich means ther is no effidence at all for a virus being millions of years old
