Birds with long legs and birds with short legs were selected for.

Birds with long legs were selected for.
Birds with long legs were selected for.

Birds with short legs were selected for.

Birds with medium-length legs were selected for.

Answer 1

When the distribution curve for leg length in a population of birds shifts to the right after a disturbance, it indicates that individuals with longer leg lengths are becoming more prevalent in the population. This suggests that the environmental changes favored birds with longer legs.

Based on this interpretation, the correct statement regarding natural selection in this population of birds is:

Birds with long legs were selected for.
