The evolution of numerous species, such as Darwin's finches from a single ancestor is called adaptive radiation.

the beaks were different on every island
There are thousands of instances of direct evidence of evolution. The most well-known example is that of Darwin's Finches. These finches were observed through fossil records to have changed over time to adapt to their environment.
The Galapagos Finches are best known for the difference in their beaks and also because they were Charles Darwin's inspiration for the Theory of Evolution.
No, evolution has created different species of finches on the Galapagos Islands. There are 15 different species that are found on the Galapagos islands.
