1. The Devonian period experienced the first significant adaptive radiation of terrestrial life. 2. Adaptive radiation of marsupials excluded competition with their terrestrial placental counterparts.3. The gradual spreading of organisms with adaptive radiation is known as divergent evolution. 4. Ants became dominant after adaptive radiation at the beginning of the Paleogene period. 5. Following this paper, Stebbins developed the first model of adaptive radiation . 6. Studies on the evolutionary trends and adaptive radiation in four genera of Lythraceae. 7. The subsequent adaptive radiation was spurred by a lack of niches. 8. The climatic changes of the late Jurassic and Cretaceous provided for further adaptive radiation . 9. Evolution of mouse lemurs is an example for adaptive radiation . 10. The first, adaptive radiation , is the result of a rapid divergence into new adaptive zones.
