向学生提供进化变化的动态本质的实际演示是很困难的。我们提出了一种模拟微进化的方法，其中糕点猎物种群会根据自由放养鸟类的选择而“进化”。向鸟类提供已知频率的种群，例如，两种类型的猎物，允许它们进食，并且在吃掉指定数量后，计算幸存者中两种类型的频率。然后出现与第一代大小相同的新“一代”，其猎物类型与上一代中幸存的捕食频率相同。该过程根据需要重复几代。我们描述了使用此方法运行的六种不同类型的模拟，并提出了更多建议。
It is difficult to provide students with a practical demonstration of trie dynamic nature of evolutionary change. We suggest a method for simulating microevolution in which populations of pastry prey ‘evolve’ in response to selection by free-ranging birds. The birds are presented with a population with known frequencies of, for example, two types of prey, they are allowed to feed and after a specified number have been eaten the frequencies of the two types in the survivors are calculated. A new ‘generation’ of the same size as the first is then presented, with the prey types in the same frequencies as survived predation in the previous generation. This procedure is repeated for as many generations as are required. We describe six different types of simulation that we have run using this method and suggest several more.
