Click the blue words to correct the following summary of natural selection. Natural selection makes certain variations more common in a population over
many generations. These variations must be advantageous, which means they
make an individual more likely to survive and reproduce in its environment. These
variations must also be advantageous, or passed down to offspring.
A change in the population's environment may make different inherited variations
more advantageous. If this happens, the most common variation in the population
will likely stay the same due to natural selection.
