  • When individuals from one side of the curve has a better fitness,  so the direction of the curve will move to the side that has a better fitness.
  • Example : Fossil records show that during the ice age White bears had a better fitness so the curve would go into that direction and the population of black bears would decrease.

The ones in the middle have a lower chance of surviving. For example, a small fish can hide from predators and big fish can eat different types of fish that are smaller. But the medium sized fish is too big to hide and it is too small to eat fish bigger than its size.

For example In humans, birth weight is an example of stabilizing selection. Babies that are born too small can lose heat too easily and may die, whereas babies being born too large can lead to complications during childbirth and the death of the mother or the baby.
