Origin of viruses

Is it also possible that viruses evolved from a more developed organism like bacteria/fungi...i.e., an advanced form of spores/similar forms which are meant just for the survival of the organism and nothing else.(I am unable to put it in proper words but i hope u understand.)I am saying this because as I understand viruses, they only exist to survive and increase their population.

I actually meant it as a question. I will be careful from the next time.

Well, I take it that "magic" means the ability to over-ride the laws of nature by an act of will. Religious people for some reason prefer to use the word "miracle" when God does it, but this is a distinction without a difference.

Hi Kiddo, And how is this different to the reason for existence of any life form? Plants, fungi, bacteria, animals - they all exist to survive and propagate their species.

all other organisms tend to increase their functionality/complexity , like secreting enzymes, developing protective coats around them, etc. But in case of viruses, they became more simpler and lost their functions rather than gaining new ones.

But regardless of complexity of operation, all lifeforms have the basic function to make more copies of themselves. Unless you can think of another reason why a mushroom pops up out of the ground.

Viruses are developing new functions all the time. They're extremely refined replicators with some of the most remarkable adaptations.

Well, it really all depends on the environment. There does seem to be a tendancy towards complexity, but this is due to available niches in the environment allowing for it. If the environment exhibits pressure towards simplicity, then that will happen too. For example, fish in caves that lost their eyes: Presumably, the same goes for viruses.

I think the suggestion is that viruses could be descended from cellular life, which found a parasitic niche that allowed them to do away with the cellular mechanisms that they could steal from their hosts.The famous experiment by Sol Spiegelman, in which he supplied a simple virus with everything it needed to replicate itself for free, and then watched it's genome shrink to a tiny fraction of its previous size, could be an elaboration of the original process by which the first viruses evolved from prokaryotic ancestors.This is all just guessing, though.
