In Central and Northern California, the Red-legged Frog (Rana aurora) breeds from January to March. The closely related Yellow-legged Frog (Rana boylii) bre through May. Based on this information, which of the following is a scientist most likely to observe if these two species of frog are studied for multiple generation The two species may experience convergent evolution due to differences in the timing of sexual activity. The two species may expenence divergent evolution due to differences in the timing of sexual activity. The two species may expenence adaptive radiation due to differences in the timing of sexual activity. The two species may expenence coevolution due to differences in the timing of sexual activity.

## Step 1<br />The problem presents two species of frogs, the Red-legged Frog (Rana aurora) and the Yellow-legged Frog (Rana boylii), which have different breeding seasons. The Red-legged Frog breeds from January to March, while the Yellow-legged Frog breeds through May.<br /><br />## Step 2<br />The question asks us to determine the type of evolution that these two species may experience due to their differences in breeding seasons. The options provided are convergent evolution, divergent evolution, adaptive radiation, and coevolution.<br /><br />## Step 3<br />Convergent evolution refers to the process where unrelated species independently evolve similar traits as they adapt to similar environments or ecological niches. This doesn't apply here as the two species are closely related and have different breeding seasons.<br /><br />## Step 4<br />Divergent evolution refers to the process where a species evolves into two or more descendant or different forms, leading to diversity. This seems to fit the scenario as the two species have different breeding seasons, which could lead to different evolutionary paths.<br /><br />## Step 5<br />Adaptive radiation refers to the process where a single species diversifies into multiple different forms to fill different ecological niches. This doesn't apply here as the two species are already different and have different breeding seasons.<br /><br />## Step 6<br />Coevolution refers to the process where two or more species reciprocally affect each other's evolution. This doesn't apply here as the two species have different breeding seasons and there's no indication of mutual influence on each other's evolution.
