cardinals and blue jays are two species of birds that occupy the same habitat zone and breed at the same time of year. Which of the following best describes how these two species developed?

1 Temporal selection

2 Behavioral isolation

3 Stabilizing selection

4 Directional selection

1 Temporal selection

Based on the information provided, the best description for how these two species developed would be option 2: Behavioral isolation. Behavioral isolation refers to a mechanism of reproductive isolation in which two species develop different mating behaviors or rituals, preventing them from interbreeding even if they occupy the same habitat and breed at the same time of year. In this case, the cardinals and blue jays have likely developed distinct courtship behaviors or other behaviors that prevent them from mating with each other.
