Death, aging, renewal (part 3) - nourishment

 

Aging

How did aging appeared?

If device of Death was selected by evolution, how was aging chosen?

Why for exemplar at a number of age animals do not die at once and just give the room for the next generation. Encouragement is one clarification at least for human society.

But lets say new cohort of young adults before now reached teenage years . Why would not old cohort die in an instant. Why do they age?

Actually there is naught impossible. Some butterflies grow combine years, mate, construct new cohort and die in one day. Some plants live 1 year, some live 2 years and then customarily die. Some live 1000 years. Lemmings, having overgrowth of population, just go and massively commit suicide in the sea. No questioned asked.

Why aging in other animals take quite a few years?

It might be select by cut-throat evolution all through an added catastrophe.

A more or less mild Catastrophe happened in the same time when all adults died involuntary to do so. Older animals would continue the disaster. But they died at once from in-house timer. Younger age group did not tolerate the mishap.

All species that did it - just disappeared. Younger animals were not adapted to new conditions. Only animals with machine of aging were selected. Maybe the aged animals are not so good as younger ones. They by now somewhat deteriorated. But it is change for the better than nothing.

Anyway. It makes sense why Death and Aging were preferred at some stage in the Evolution.
