Answer 3

I'd say "two populations of finches that cannot produce viable offspring". This is an example of reproductive isolation because the differences in habitat or environment would prevent such interaction, and even cause one of the populations to evolve where-areas the others don't. The perfect example of this would be the ring-tailed lemurs on Madagascar.
