How did the artificial selection practiced by pigeon breeders influence Darwin's theory of evolution by natural selection? A. Darwin concluded that if breeders could select for certain traits in pigeons, they could also select for certain traits in saddleback tortoises. B. Darwin concluded that if traits in captive pigeons could be selectively passed on to offspring, the selection of traits could also happen in nature. C. Darwin concluded that if pigeons could choose their own traits, then animals in the wild could also choose their own traits. D. Darwin concluded that if artificial selection could change a population over time, it could change a population instantly as well.
