zhuklara [117]

Answer:

The correct answer is the option - mating factor.

Answer:

The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.

It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.
