有关生命历史进化(繁殖和生存的时间表)的理论侧重于描述使健康最大化的生命历史。尽管生活史和健康之间存在着直观的联系，但实际上，健康的黑匣子概念有几个衡量标准。在生物数学文献中，关于内在增长率和净繁殖率R-0这两个最常用的指标之间的预测差异一直存在争议。尽管这两个衡量标准都旨在描述适合度，但使用其中一个衡量标准的模型可能会预测使用另一个衡量标准的类似模型的相反情况，这显然是不可取的。在这里，我回顾了这些健身指标在过去40年中的演变，这些指标之间的预测差异，以及由此导致的健身概念的转变。我特别关注最近的一些发展，这些发展通过明确承认生命历史进化的博弈论性质，解决了这些健康指标之间预测差异的困境。
Theory concerning the evolution of life history (the schedule of reproduction and survival) focuses on describing the life history which maximises fitness. Although there is an intuitive link between life history and fitness, there are in fact several measures of the 'black box' concept of fitness. There has been a debate in the bio-mathematical literature on the predictive difference between the two most commonly used measures; intrinsic rate of increase, and net reproductive ratio R-0. Although both measures aim to describe fitness, models using one of the measures may predict the opposite of similar models using the other measure, which is clearly undesirable. Here, I review the evolution of these fitness measures over the last four decades, the predictive differences between these measures and the resulting shift of the fitness concept. I focus in particular on some recent developments, which have solved the dilemma of predictive differences between these fitness measures by explicitly acknowledging the game-theoretical nature of life-history evolution.
