1953年在伯明翰工业区附近进行的一系列实验（凯特韦尔，遗传学9：第3部分）在英格兰多塞特郡未受污染的乡村进行。1955年12月）。在每一个，已知数量的黑色和浅色形式的比斯顿betularia（胡椒蛾）被标记和释放到当地人口和一部分随后被重新捕获。在目前的实验中，984个标记的个人被释放在一个严重的地衣木材，黑色形式carbonaria通常不会发生; 96随后被重新捕获。这代表了典型的浅色形式的12.5%的回归，但只有黑色碳质形式的6.3%。这种差异被证明是由于鸟类的选择性捕食，与工业区的情况相反。伯明翰实验的重复也被记录下来。|| 摘要：H. B。D.凯特韦尔
A companion series of experiments was undertaken in the unpolluted countryside of Dorset, England, to that undertaken near the industrial area of Birmingham in 1953 (Kettlewell, Heredity 9 : Part 3. December 1955). In each, known numbers of the black and light form of Biston betularia (the peppered moth) were marked and released into the local population and a portion was subsequently recaptured. In the current experiments, 984 marked individuals were set free in a heavily lichened wood where the black form carbonaria does not normally occur; 96 were recaptured subsequently. This represented a return of 12.5% of the typical light form, but only 6.3% of the black carbonaria form. The difference was shown to be due to selective predation by birds, and is the reverse of what was found in an industrial area. A repetition of the Birmingham experiments is also recorded. || ABSTRACT AUTHORS: H. B. D. Kettlewell
