Question

Quizplus · Accepted Answer

Webbed feet on a bird are an evolutionary adaptation that help it swim in water and catch prey, thus increasing its chances of survival and reproduction. The other choices are not evolutionary adaptations as they do not involve changes in the genes of a population over time. Vaccination and ear clipping are individual interventions, while Dumpster opening is a learned behavior.
