Researchers plotted a distribution curve 4 leg length in a population of birds, with length from short 2 long on da x-axis. Da curve shifts 2 da right after a disturbance. Which statement is correct abut natural selection in dis population of birds?

Question

A ) Birds with long legs were selected 4

B ) Birds with short legs were selected 4

C ) Birds with long legs n birds with short legs were selected 4

D ) Birds with medium-length legs were selected 4

Answer 1

If the distribution curve for leg length in the bird population shifts to the right after a disturbance, it indicates that the average leg length in the population has increased. This suggests that birds with longer legs have been favored or selected for in the population.

Therefore, the correct statement about natural selection in this population of birds is:

A) Birds with long legs were selected for.
