You have to remember that evolution doesn't occure due to a need, or for any intelligent reason. It's totally random, and if the trait increases the chance of the creature surviving it gets passed on. Since aging gives no immediate advantage that would help a creature survive (quite the opposite actually), it's unlikely that it would be passed on.
You also have to consider that aging is an inherent by-product of our cell's designs. It would be almost impossible for creatures who have cells that are similar to our own at even the most basic level to not age.
Actually need is exactly why evolution occurs. A cuckoo will lay its eggs in a nest of one specific species of bird. If the bird realizes that the egg it got in its nest is not of its own species it wont put any effort into hatching the egg. Is it random that the cuckoo got mimicry that makes the egg look as much like the egg of its victim?
Take the fly orchid. It resembles a female fly to the point of having pheromones to attract male flies to pollinate it. I don't think that's something that just happen to occur by chance. The flower even blossoms before the female flies of that species are ready to mate so the male flies will try to mate with the flower because there is no female flies at all to mate with. There's a need and it evolved to it.
Sure, mutations are random and you can't predict them, but if a mutation isn't beneficial or if it's downright a negative thing it's not evolution. It's a character that will most likely disappear. A peacock is a product of evolution. An albino peacock is a random mutation.
its not need, and what you just said doesnt prove it at all, infact im not sure how your trying to prove you're point
its just random mutation, if it works then there is a good chance it will get passed on, simple as that, eventually the things with the new traits succeed very well and the ones without it die off
and if its not beneficial its not evolution? take a single celled organism, its just one cell but it has mutations every time it reproduces and the one cell still dies, now take one of your skin cells, every time you reproduce there is a chance your child's skin my have some better quality, however you skin cell, along with any cell in your body will die and be replaced
considering that cells die, and most of the time the cells in your body dont last that much longer than microbes anyway, is there any "benefit" for that single cell organism to turn into a multicellular organism? not really but it was still evolution
