Answer :
The correct answer is A. Environmental conditions allowed finches with certain beak shapes to obtain more food, survive longer, and reproduce more.
According to Darwin's theory of evolution by natural selection, organisms that possess advantageous traits in a given environment are more likely to survive, reproduce, and pass on those traits to the next generation. In the case of the finches in the Galapagos Islands, their beak shapes have diversified due to variations in environmental conditions and food availability on different islands.
Different types of food sources require different beak shapes for efficient feeding. For example, finches with long, narrow beaks are better suited for extracting insects from tree bark, while those with short, stout beaks are more adept at cracking seeds. When environmental conditions favored certain types of food, finches with beak shapes that allowed them to access and exploit those resources more effectively had a survival advantage. Over time, these advantageous traits were passed down to subsequent generations, leading to the diversification of finch beak shapes.

Answer:
A. Environmental conditions allowed finches with certain beak shapes to obtain more food, survive longer, and reproduce more.
Explanation:
Darwin's Theory derives from evolution, which can take thousands of years to become apparent. This automatically eliminates B as an answer choice. Since it asks about Darwin's theory, D cannot be correct because it has no content from the actual theory. C can be correct, but it makes no mention of Darwin's theory and doesn't specify why the beaks changed. The correct answer is A.
