right
Since Darwin found many species of plants he found many species of finches. Those species, just like the warbler finch, were found on the Galapagos Islands.
By adaptive radiation. The original finch emigrated to the Galapagos Islands and found many different environments and feeding opportunities per individual Island. So, under this new selection pressure and the random mutational variation all species have, many new species of finch arose on all the various Islands of the Galapagos.

There are 10 recognized species of Galapagos giant tortoises.

Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.
