The northern red-legged frog, or *Rana aurora*, is found along the western coast from British Columbia to Northern California. Their typical breeding season lasts from January to March. The foothill yellow-legged frog, or *Rana boylii*, is found along the western coast from northern Oregon to central California. Their typical breeding season lasts from April to July. What mechanism might keep *Rana aurora* and *Rana boylii* from mating?- ❍ anatomical isolation- ❍ temporal isolation- ❍ geographic isolation- ❍ behavioral isolation ### Darwin's Experiment on SpeciationDarwin hypothesized that new species could appear gradually through small changes in an ancestral species. What experiment did he conduct to test this hypothesis?- ⭘ the breeding of finches- ⭘ the breeding of pigeons- ⭘ the observation of humans- ⭘ the observation of dog breeds**Explanation:**This text is a multiple-choice question about Charles Darwin's research methods concerning the development of new species through incremental changes. The question specifically inquires which experiment Darwin conducted to test his hypothesis. The options provided include breeding experiments and observational studies on different organisms.
