最近发展起来的比较方法可以用来确定统计学上独立的生活史进化的实例。当生活史特征显示出相互之间或与生态差异相关的进化变化的证据时，通常可以挑出负责生活史多样性进化的权衡和选择力。生活史上的人物往往会在音乐会上进化，最近的最优模型纳入几个变量显示承诺解释进化的几个选择力。由于宿主为它们的寄生虫提供了明确的环境，当宿主-寄生虫的生殖一致时，就有可能测试关于特定生活史和大小相关性状进化的想法。
The comparative method as recently developed can be used to identify statistically independent instances of life-history evolution. When life-history traits show evidence for correlated evolutionary change with each other or with ecological differences, it is often possible to single out the trade-offs and selective forces responsible for the evolution of life-history diversity. Suites of life-history characters often evolve in concert, and recent optimality models incorporating few variables show promise for interpreting that evolution in terms of few selective forces. Because hosts provide well-defined environments for their parasites, when host-parasite phylogenies are congruent it is possible to test ideas about the evolution of particular life-history and size-related traits.
