Stabilizing selection is a type of natural selection. An example of stabilizing selection is birth weigh in humans. It has been proven that early mortality is highest for extreme birth weights.
Natural selection refers to the process that allows one species to better adapt to its environment than other species and allow it to survive. One example might be two grasshoppers, one green and one brown. In the same open green field, the brown grasshopper may be eaten more by birds or other animals due to its color not giving it as much camouflage and protection as the green grasshopper. The green grasshopper will reproduce more rapidly due to the larger numbers available compared to the brown grasshopper. The brown grasshopper will eventually die out because of this natural selection.
Human birth weight is an example of stabilizing selection for an average morphology. Not to small, so heat is lost rapidly and not too large so birth problems are avoided.

That is the definition of stabilizing selection.
Stabilizing selection results in less genetic diversity in a population.
Stabilizing selection.
The average, distributed normally, trait in phenotype of a population is selected for. Take height in humans as an example. We have variation there, but there are too few ten foot humans and too few 2 foot hymans in the human population because natural selection in it's stabilizing form makes such height extremes reproductively unsuccessful in all earth's immediate environments.
When the average, or mean of a population of organisms are selected for. The immediate environment admits of only one way a garnering resources, for instance. Thus, the extremes of the population have lesser chances of survival.
Directional selection
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
