An archipelago is basically a group of islands. Speciation according to the Biological Species Concept by Ernest Mayr, is -- populations whose members can interbreed and produce viable, fertile offspring. For example, the Galapagos finches studied by Charles Darwin. Some live on different parts of the archipelago and so have different features, adapting to their environment. These different feature obviously get passed down and are more frequent in future populations because those finches with this specific adaptation lived and reproduced better. So since there are different islands, there are different finch speciation and so the geographic isolation promotes speciation.

the formation of species
I will assume the word you are looking for is speciation. Perhaps adaptive speciation to be precise.
Sympatric Speciation
Speciation adds to biodiversity. Hence it affect the evolution of best suited forms to come up.
how is natural selection occurring in the pollenpeepers
Neutral variation and Diploidy.
Allopatric speciation.
what are the advantages of the archipelago?
sympatric , allopatric and parapatric speciation
The Malay Archipelago (or Indonesian Archipelago) is often referred to as the largest archipelago in the world.
Isolation Is necessary for speciation to occur.
Actually it is.

The noun archipelago is used for an archipelago of islands.
