they evolve to fill new niches
The general term for the formation of a new species is speciation.
Over billions and billions of years, an entire species slowly develops characteristics that they need to adapt to current conditions. If this is repeated enough times, a new species completely different from the original can "form". Or if you're really religious, your God makes new species or whatever.
For a new species to form, there must be a long string of mutations and developments based on some environmental need. Eventually enough changes will occur that the organisms that have made the change are no longer recognizable as their original species.
That process is called Speciation!
They can be formed by evolution: A species can't survive in it's environment so it evolves into a more adapted species Two different species can mate: A new species can appear from the offspring of two different species.

Islands are relatively isolated environments, so there it is less likely that an existing species will move in and outcompete a developing one, and also easier for an existing species to die out since there aren't external populations to replace them. This instability means that the environment can change more quickly, and therefore species must adapt more quickly, compared to the relatively stable environment on the mainland.
he noticed that there were different species of animals on different islands which he concluded was from speciation. the geologic form of the different islands led him to the conclusion that they were once a single species on one island.

There is not 13 different species of finches, there are one species. There are variations, but still one species. There are 250 different breeds of dogs, but still dog species

Solomon Islands is a part of Melanesia since Melanesia includes the islands of New Guinea, Vanuatu (the former New Hebrides), New Caledonia, the Solomon Islands, and some smaller neighboring islands.
The Chatham Islands are located in the Pacific Ocean south of the country of New Zealand. The Chatham Islands are composed of 10 islands and form an archipelago.
