State

Stabilizing selection favors individuals near a population's average phenotype and selects against both extremes, reducing overall phenotypic variation over time.

Show

Mice whose fur color most closely matches the forest floor's average shade survive better than noticeably lighter or darker mice.

Watch for

Stabilizing selection decreases variation around a stable average — it does not shift the average phenotype in any new direction.
