Answer:

A. Some speculate that they were blown out to the islands by a massive storm

Explanation:

The common rosefinches are thought to have arrived on the Hawaii islands between 6 and 7 million years ago. As the common rosefinches are not big birds and they can not fly over very long distances, the scientists believe that it is a massive storm that blow some individuals to the Hawaii islands. This is nothing weird, as it has been witnessed numerous times how massive storms manage to carry some smaller birds to places where they are not able to fly on their own. Once there, the birds encountered suitable conditions for living and lot of open niches in the food chain. This resulted in quick diversification of the common rosefinches, with members of the species gradually adapting to a particular niche, experiencing changes to be more competent, and creating numerous new species after some time.

Answer:

Fossil fuels are produced by the same geological processes.

Fossil fuels form when organic matter which has been buried in the Earth over a long period of time is subjected to heat and pressure over a long period of time. Heat and pressure are both critical components for the formation of a fossil fuel. The process of the formation of fossil fuel is the same today as it was in the past. The geological processes are the same for the formation of fossils.
