State

Adaptive radiation is the rapid formation of many new species from one ancestral species as its descendants adapt to distinct, isolated niches.

Show

Hawaiian honeycreepers radiated from one founder species into many species, each with a beak shaped for a different food source.

Watch for

Adaptive radiation is many speciation events from one founder species — not one species spreading unchanged into new territory.
