Explain Adaptive Radiation
One species changes into many other species so that it can live in different places. This is called adaptive radiation. This happens when a group of creatures moves or their environment changes, causing them to develop new traits that help them stay alive in their new environment.
Darwin's finches on the Galápagos Islands are a well-known case. All of these birds are related to each other, but as they moved to different places, their beaks changed to fit the seeds, insects, or nectar that they found there. It's the same parent that led to many different animals, like kangaroos, koalas, and bandicoots, each of which evolved to live in a different environment. This is also true for cichlid fish in lakes in Africa. Hundreds of species have evolved from a single ancestor to play different parts in the ecosystem.
Basically, adaptive radiation is how nature helps living things change and stay alive in new places. This is how the wide range of life we see today came to be.
