描述了一组实验，测试的一般假设，同域物种形成是遗传上可行的生殖隔离时，间接演变为一个相关的字符。我们专门测试的假设，破坏性选择的栖息地偏好可能会导致同域物种形成时，个人在当地交配他们所选择的栖息地。以果蝇为模型系统。一个35代的实验，使用复杂的栖息地迷宫导致完全的生殖隔离亚群之间使用不同的时空栖息地。在实验过程中形成的生殖隔离是后代回到父母选择的栖息地类型交配的结果，即，栖息地之间迁徙的逐渐中断。
A set of experiments is described that tests the general hypothesis that sympatric speciation is genetically feasible whenever reproductive isolation evolves indirectly as a correlated character. We specifically test the hypothesis that disruptive selection on habitat preference can lead to sympatric speciation when individuals mate locally within their selected habitat. Drospophila melanogaster was used as a model system. A 35-generation experiment using a complex habitat maze led to complete reproductive isolation between subpopulations using different spatiotemporal habitats. The reproductive isolation that developed over the course of the experiment was a result of offspring returning to mate in the habitat type selected by their parents, i.e., a gradual breakdown in migration between habitats.
