进化变化是否可以通过遗传同化或更普遍的遗传适应发生，仍然存在争议。在这里，我们研究了这两种现象的一些实验证据。在果蝇中进行的几项实验表明，同化是可能的，一篇新论文（1）表明，烟草天蛾（Manduca sexta）的颜色多型性可以通过遗传适应进化。我们认为，遗传适应，包括同化，是一个合理的机制在进化中，然而，需要更多的工作来测试这种机制是如何发挥作用，以及它是如何经常参与进化的变化。
Whether evolutionary change can occur by genetic assimilation, or more generally by genetic accommodation, remains controversial. Here we examine some of the experimental evidence for both phenomena. Several experiments in Drosophila suggest that assimilation is possible, and a new paper((1)) shows that a color polyphenism in the tobacco hornworm, Manduca sexta, can evolve by genetic accommodation. We argue that genetic accommodation, including assimilation, is a plausible mechanism in evolution; however, more work is required to test how this mechanism acts and how often it is involved in evolutionary change.
