自从J.B.S.霍尔丹提出这一想法以来，进化生物学家们意识到，个体水平的适应并不一定会导致最优的种群表现。一些来自不同系统的深度数学模型甚至预测，个体选择可能导致整个种群的灭绝，这一现象已被称为进化自杀。由于遵循适应和确定灭绝的确切原因都很复杂，进化性自杀仍然没有得到经验上的检验。然而，最近的三项实证研究表明，自杀是可能发生的，自杀应该被视为一种潜在的重要进化现象。在这里，我们简要回顾了理论和经验证据，询问是否会发生进化性自杀。我们进一步强调了可以用来测试个体水平选择是否会导致灭绝的系统。
Ever since J.B.S. Haldane proposed the idea, evolutionary biologists are aware that individual level adaptations do not necessarily lead to optimal population performance. A few deeply mathematical models, drawing from a diverse range of systems, even predict that individual selection can lead to the extinction of the whole population, a phenomenon which has become known as evolutionary suicide. Due to the complexity of both following adaptation and determining the exact cause of an extinction, evolutionary suicide has remained untested empirically. However, three recent empirical studies suggest that it may occur, and that suicide should be taken seriously as a potentially important evolutionary phenomenon. Here we ask whether or not evolutionary suicide can occur, briefly reviewing the theoretical and empirical evidence. We further highlight systems which may be used to test whether or not individual level selection can cause extinction.
