By analyzing the morphological and genetic differences among populations of species of frogs in the high Andes in Peru by cladistic methods, it will be possible to determine the evolutionary relationships of five lineages of frogs. Once this has been accomplished, repetitive patterns of species formation and biogeography will be compared with existing data on historic patterns of climatic and geologic changes. The results will provide an interpretation of how such changes affected the speciation and distributions of the frogs and will provide a basis for comparison with other groups of organisms.

通过对秘鲁高海拔安第斯山脉蛙类种群的形态学和遗传学差异的分析，可以确定蛙类5个谱系的进化关系。一旦完成这项工作，将把物种形成和地理分布的重复模式与气候和地质变化历史模式的现有数据进行比较。这些结果将解释这些变化如何影响青蛙的物种形成和分布，并将为与其他生物群体进行比较提供基础。
