Excuse me for jumping in here Sapiens, but I couldn't resist.
Actually, the climate is the same for all 21 islands. Variations in weather only present where there is an appreciable change in elevation: The highlands have significantly more rain than the lowlands.
Whether or not they're
becoming something new, as in new species, is impossible to say. That's something only the future can reveal. However, they
did become something new. They
became new species.
And your point?
What methods are these?

Are they still finches?
How many different breeds of dogs exist? are they all still dogs?
inbreeding creates many 'mongrels' , but how many are called 'new species'?
If humans inbreed enough, and look different from 'the norm', and upon first blush it may be difficult to distinguish their 'race' or 'nationality', do you call that a 'new species'? Hardly
Does natural selection really create an entirely new species?
Finches are still finches. not a new species.

Adaption and Natural Selection, by George C. Williams, 1966, p. 54.
There is no end to attempts to mislead people and turn them away from the reality that there IS A Creator, and hold them responsible for their own actions, rather than blowing it all off with the fake Big Bang and other God dishonoring 'theories'.
If that is what people desire in their hearts, then go for it. Any thinking persons who are sincere in their hearts when seeking the knowledge that saves lives, as per John 17:3, will be able to determine the aggressive fake attempts to discredit the Creator and find refreshment for their souls in the Bible truths that lead to everlasting life.
Peace to you
