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

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

Answer 1

The correct statement is:

• Birds with long legs were selected for.

A shift to the right in the distribution curve for leg length indicates that the average leg length in the population has increased, suggesting that birds with longer legs were favored by natural selection following the disturbance.
