保护遗传学可以被看作是以增强种群持久性的方式影响进化过程的努力。许多已发表的研究在该领域应用遗传抽样技术来推断人口参数的变化模式在受威胁的人口。这些推论的有限分辨率似乎产生有限的信心，导致保守的政策建议。作为一种替代方案，我建议保护遗传学关注这些变量之间的关系，保护主义者可以控制，和理想的进化结果的概率。这项研究将包括三个阶段-更多地利用现有的进化理论;利用实验进化来测试管理方案;以及在适应性管理框架下进行“实地试验”。它将采取概率方法，承认进化变化中固有的随机性。这将允许一个更微妙的方法来保护政策比经验法则的指导方针。此外，它将利用进化论是生物学中的统一理论这一事实，并利用过去半个世纪建立起来的大量进化知识。
Conservation genetics can be seen as the effort to influence the evolutionary process in ways that enhance the persistence of populations. Much published research in the field applies genetic sampling techniques to infer population parameters from the patterns of variation in threatened populations. The limited resolution of these inferences seems to yield limited confidence which results in conservative policy recommendations. As an alternative, I suggest that conservation genetics focus on the relationships between those variables conservationists can control, and the probability of desirable evolutionary outcomes. This research would involve three phases – a greater use of existing evolutionary theory; testing management options using experimental evolution; and ‘field trials’ under an adaptive management framework. It would take a probabilistic approach that recognizes the stochasticity inherent in evolutionary change. This would allow a more nuanced approach to conservation policy than rule of thumb guidelines. Moreover, it would capitalize on the fact that evolution is a unifying theory in biology and draw on the substantial body of evolutionary knowledge that has been built up over the last half a century.
