作为程序性自我分解研究的一部分，我们形成了一个假设，即原本不朽的陆地生物进化成程序性自主死亡的生物。然后，我们进行了进化模拟实验，在实验中，我们使用一个人工生态系统来检验这一假设，我们设计了一个类似于被赋予人工化学的陆地生态系统的人工生态系统。得到的显著结果证实了我们的假设：可死生物是由本地不朽生物通过突变产生的；这些必死的生物存活下来，并留下后代，尽管很少，而且，存活下来，毫无例外地超过了不朽的生物。在本文中，我们报告了上述发现的细节，并讨论了我们之前为接近利他主义构建的背景框架。
As part of our research on programmed self-decomposition, we formed the hypothesis that originally immortal terrestrial organisms evolve into ones that are programmed for autonomous death. We then conducted evolutionary simulation experiments in which we examined this hypothesis using an artificial ecosystem that we designed to resemble a terrestrial ecosystem endowed with artificial chemistry. Notable results corroborating our hypothesis were obtained, which showed that mortal organisms emerged from indigenous immortal organisms through mutation; such mortal organisms survived and left behind offspring, albeit very rarely, and, having survived, surpassed immortal organisms without exception. In this article, we report the details of the above findings and also discuss a background framework we previously constructed for approaching altruism.
