No internal organs can be regrown except the liver True but all our organs are continually being replaced with new cells, and when injured, they heal.
There is no reason whatsoever for a cell to die other than an enzyme
I remember hearing a series of lectures on longevity by medical reasearchers and biochemist working on the problem. One of them's statement stayed with me. She said the fundamental problem they face is that on the cellular level, the processes of aging is the same as the processes of living.Kind of like natural curing addiction with addiction.
There are good, bad, good/bad and neutral mutations. Of course, you would point out that these qualifiers are man-made or at least from man's perspective. In the long run, we don't know.
Procreation problems could have been naturally adjusted by adjusting reproductive periods and estrus duration, sharply reducing offspring numbers.
That occurs, or similar adjustments, already. Predators and resource depletion also contribute. This means cataclysm for the species involved, with man it would be approaching Armageddon.That doesn't strike me as an intelligent design but a reactive design.
I think you likely don't see "design" in the picture, but life eating life to live is IMHO more than reactive. It's the way the whole system works, everything is part of many cycles, interdependent. Not only food, but oxygen, nitrogen, water, minerals, etc. etc.
At some point radiation and other factors damage our cells leading to breakdown.
Radiation also causes mutations - ones that help us survive as well.
So, all this seems to be adaptive.
I don't think you mean adaptive here, unless you're saying the underlying process of creation is adaptive and designing.
When longevity becomes an essential survival tool the body will turn on telomerase and prolong cell-life.
Just a personal opinion, I doubt this factor will affect unless/until reproduction occurs in old age.
For a changing world
That's the key, we live in a world of constant change, nothing stays the same. You can't build a once-and-for-all system. It must incorporate change. It seems to be teleological. From matter to one cell life, to multi-cell, to intelligence, to consciousness, to... ?
Thanks again for your reply.
True but all our organs are continually being replaced with new cells, and when injured, they heal. Not heart cells, not brain cells. You can't regrow limbs, eyes, lungs, kidneys, etc. These organs are formed during cell differentiation (organogensis) by stem cells.
Some organs, such as bones, skin, hair, blood vessels, etc. can repair and even enlarge, as needed, but these are maintenance and band-aid repair corrections.
This means cataclysm for the species involved, with man it would be approaching Armageddon
I wouldn't call it that. It happens in the universe all the time, just different places and times. We could just as easily cause it ourselves with a nuclear war. Species don't matter. Life is consequential to conditions.
This world existed long before we did, and so did many species. We see species appear and disappear in front of our eyes without cataclysms,

and something else fills the void to maintain the balance. The creation is not about us, for us or by us. We only believe it is. The world would not end if humans disappeared. Just us and our man-made things. We are not as big or important as we think we are.
