Programmed death theory revised with artificial evolution

In this we revise the Weismann`s idea of againg and death as adaptive traits. First, we analyse the adaptation process to changing environment of isolated populations (species) having different lifetime and show, that short lifetime may have adaptive value at a population level. Next, we use a Markov chain to model a competition between indyviduals in a finite population. We derive a condition for equilibrium in the population and explain why the long-lived indyviduals usually dominate the population, it would require an extraordinary environment for programmed death to be stable adaptive trait.
