[QUOTE="Jamdoc, post: 74806657, member: 423546"] Glad you understand that evolution is not necessarily making 'better' life forms but rather just hereditary change over time. Viruses as far as I know are descended from obligate intracellular parasitic bacteria, like [I]Chlamydia trachomatis[/I], a bacteria that acts much like a virus, cannot reproduce outside of a host cell, and has a small genome because it no longer codes for the parts that it would need to survive outside of a host cell. Replicating the DNA with errors it loses some of its genome over time, becoming less and less able to live on its own and eventually becoming an obligate parasite, then it starts losing the DNA needed to make the structures that compose its cells.. that's how you ultimately get a virus.. strip a lifeform down to the bare minimal DNA needed to reproduce, and it gets to a point where people think it is not even alive anymore. I think it still is life though, because it came from life. Life begets life. [/QUOTE]
