Question

Quizplus · Accepted Answer

Stabilizing selection favors the average phenotype and reduces variation in a population. In this case, sparrows with average-sized wings are better adapted to survive severe storms, which means that individuals with longer or shorter wings are at a disadvantage and are less likely to survive and reproduce. This ultimately leads to stabilizing selection favoring the average-sized wings.
