Did death evolve?

Discussion of the distribution and abundance of living organisms and how these properties are affected by interactions between the organisms and their environment

If this would be again connected with our relationship with God, it is more of God's love for us. He let us experience death.

I suppose the first organisms are immortal, accurately they are organic polymers but not organisms. Today they are still living inside of all of the creatures, from viruses to whales. They are RNA, protein and DNA. Whatever the time goes on, they will keep their form till eternity.

God just exists in our meme but not in our real life.

I believe that death is inevitable. The first organism where simple, single celled organism unlike the complexities of humans and animals. Like someone stated earlier, they had some form of death by division in which the initial cell (call it patient zero or whatever) split into two new cells which then also split into new cells as well. You do have some form of patient zero's existence in each new cell as it serves as a template during Mitosis but their type of death is completely different to us more complex organisms who grow by Meiosis.

Also, for any time of evolution to occur, one of five stabilizing conditiongs must occur:
1.) Genetic Drift
2.) Genetic Flow
3.) Mutation
4.) Equal Success
5.) Selective Mating

If life did not evolve from a simple organism to one that's complex, the reality as we know it would be filled with single celled organisms. Yet through their endless division and exposure to raw materials, evolution is inevitable and will always occur. I believe that life and death go hand in hand no matter what the organism.

Death is experienced so as to end man's fate to continue working and doing.

I don't remember who said this, but:

Life cannot exist without death, just as death cannot exist without life.

As soon as the first cell came into existence, it became susceptible to death by environmental factors. If you are talking about death by apoptosis, death did evolve (single cell organisms do not need it).
Most (if not all) multicellular organisms require apoptosis. In order to look like anything but a big formless blob of cell, multicellular organisms need some of their cells to die in an ordered fashion (by apoptosis). Any time cells lose their ability to undergo apoptosis (like in cancer), they lead to disruption organisms overall function and can cause death.

And as what I remember of cancerous cells--"immortal" as they may seem.
