Natural selection has some limits, which can include the fact that
Select one:
a. Organisms with short generation times are less responsive to environmental change.
b. Species cannot evolve quickly enough to explain the diversity we see today.
c. It can only select for stronger faster organisms, not for resilience in times of change.
d. There must be genetic variation in a population for natural selection to occur.
d. There must be genetic variation in a population for natural selection to occur.
