Evolution concerns continuity beyond individual lifetimes.
The persistence of life is not confined to organisms existing at a single moment. Organisational achievements can extend across generations through inheritance, reproduction, development, and historical continuity.
This continuity is never exact repetition.
Inheritance preserves aspects of previous organisation while variation introduces novelty and change.
Evolution therefore combines continuity and transformation within a single historical process.
The living world exists because continuity has been maintained across billions of years despite continual modification.
Evolution is the continuity architecture through which organised persistence becomes historical.
