An analysis of the interpopulational differences observed between four European and four Chilean stocks of Drosophila subobscura, with regard to wing size, egg-to-adult development time and preadult viability, shows highly significant differences between the eight stocks irrespective of the continent from which the flies are derived. The divergence of the local populations with regard to the quantitative traits described here, supplements other evidence of interpopulational differences in mating activity, chromosomal and enzyme polymorphisms. These together indicate that the evolutionary process that promotes race formation is relatively rapid, bearing in mind that D. subobscura was detected for the first time in South America in 1978.
对四个欧洲果蝇和四个智利果蝇亚暗果蝇种群之间观察到的种群间差异进行分析，涉及翅大小、卵到成虫发育时间和成虫前期活力，结果表明，无论果蝇来自哪个大陆，这八个种群之间都存在高度显著的差异。当地种群在本文所述数量性状方面的差异，补充了交配活动、染色体和酶多态性方面种群间差异的其他证据。考虑到1978年在南美洲首次发现亚暗果蝇，这些共同表明促进种族形成的进化过程相对较快。
