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)

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

1 answer

• Birds with long legs were selected for.

Explanation: The shift to the right in the distribution curve indicates that birds with longer legs were favored by natural selection after the disturbance. This suggests that there may be an advantage to having longer legs in the population.
