It takes foresight to make complex tools and procedures that can restore the functions of other tools. A blind process can only see the immediate present.
Even tissues have to deal with the dead, and like everything else they do, they excel at it. The number of players involved in cell death is truly astonishing.
No one knows how apoptosis came to be, although there are theories. Even the simplest of animals are programmed for it.
