When a related species adapts to a different environment?

When a related species adapts to a different environment, it undergoes a process called adaptive radiation. This occurs when species evolve distinct traits that enhance their survival and reproduction in varied habitats, often leading to morphological, behavioral, or physiological changes. For example, Darwin's finches adapted to different islands in the Galápagos by developing different beak shapes suited for available food sources. These adaptations illustrate how environmental pressures can drive evolutionary change within related species.
