Question

Use evidence from the Grants’ research to explain how natural selection leads to evolution. (10 points)

Answer 1

Answer:

The correct answer is - Grant's research on finches on the Galapagos islands.

Explanation:

Grant's research was made on medium-sized finches on the Galapagos islands showed evolutionary processes in real-time. He showed that due to the drought there is a decrease in the number of small and soft seeds that were finches major food source.

It is known that there are different beak sizes in this finch species, the finches with larger beaks could feed on tough and large seeds and survive in such case of the drought-induced decrease in food availability. Due to this natural selection and adaption the number of larger beaks in finches is increased over the real time.
