Researchers plotted a distribution curve for leg length in a population of birds, with length from short to long on the x-axis. The curve shifts to the right after a disturbance. Which statement is correct about natural selection in this population of birds?(1 point)

Question

Responses

Birds with medium-length legs were selected for.
Birds with medium-length legs were selected for.

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

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

Birds with short legs were selected for.

Answer 1

If the distribution curve for leg length in the population of birds shifts to the right after a disturbance, this indicates that the average leg length is increasing. In this context, it suggests that birds with longer legs are more successful in surviving and reproducing as a result of the disturbance.

Based on this information, the correct statement about natural selection in this population of birds is:

Birds with long legs were selected for.
