Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one.  Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.
