Darwin observed how farmers and breeders produced many kinds of farm animals and plants. These plants and animals had traits that were desired by the farmers and breeders. He also noticed how the study of similar body structures and vestigial organs could add to the evidence of evolution. After performing several breeding experiments, he came to certain conclusions and formulated some theories. His theory of evolution and natural selection is the most accepted one. What is the reason behind the acceptance of Darwin's theory?

Answers

Natural selection was actually accepted by a lot of people who knew what Darwin was talking about (e.g. Scientists and biologists..and other scientist relative to science were called).
 Darwin  was the first to realize the mechanisms that fundamentally drive this change: variation and natural selection. His theory caused controversy among his contemporaries but were  gradually accepted. Darwin's theory earned general scientific acceptance after he published his "On the Origin of Species" in 1859.
