Which is the first step that occurred in the speciation of the galapagos finches?

The first step that occurred in the speciation of the Galapagos Finches was the appearance of the founder species as it was completely devoid of the plants and animal life when it appeared above the water for the first time.

Then the members of this founder species were separated into sub-groups when the islands were separated due to tectonic movements.

The isolated groups develop different beaks and other traits as an adaptation towards the food and conditions available in different islands.

Over the period of million of years, the sub-groups evolved into different species.
