Answer:
The correct answer will be option-D.
Explanation:
Darwin is best known for his theory of evolution which he proposes after collecting the specimens of plants and animals on his voyage.
He observed the similarity and differences of the morphological pattern as well as the species present in the area. On the basis of his conclusions, he suggested that organism get traits from their parents and species to change over time also called descent with modification.
One of the evidence that supported his concept is that he observed plant species in South America and found that these species closely resembled the species of the tropical regions of South America rather than species of the temperate region of Europe as the habitat was same.
Thus, option-D is the correct answer.
