Definition: Disruptive selection is natural selection that favors individuals with extreme traits at both ends and selects against average traits.

Examples:
1) If a bird species feeds on only very small seeds or very large seeds, birds with very small or very large beaks survive best while medium-beaked birds do poorly.
2) In a landscape with dark rocks and light sand, very dark and very light mice are camouflaged and survive more often than medium-colored mice.

Short sentence using it (9th grade level): Disruptive selection can cause a population to split into two different forms when the middle type doesn't survive well.
