A variety of theoretical models incorporate phenotypes expressed in the external environment, but a core question is whether such traits generate dynamics that alter evolution. This has proven to be a challenging and controversial proposition. However, several recent modelling frameworks provide insight: indirect genetic effect (IGE) models, niche construction models, and evolutionary feedback models. These distinct approaches converge upon the observation that gene action at a distance generates feedback that expands the range of trait values and evolutionary rates that we should expect to observe in empirical studies. Such conceptual replication provides solid evidence that traits with extended effects have important evolutionary consequences, but more empirical work is needed to evaluate the predictive power of different modelling approaches.
多种理论模型将表型纳入到外部环境中，但核心问题是这些特征是否会产生改变进化的动态。这被证明是一个具有挑战性和争议性的命题。然而，最近的几个建模框架提供了一些启示：间接遗传效应（IGE）模型、生态位构建模型和进化反馈模型。这些不同的方法都得出了一个观察结果，即远距离的基因作用会产生反馈，从而扩大了我们在实证研究中应该预期观察到的特征值和进化率的范围。这种概念复制提供了确凿的证据，表明具有扩展效应的特征具有重要的进化后果，但需要更多的实证工作来评估不同建模方法的预测能力。
