Why was charles darwin able to offer a large amount of evidence for his theory of evolution by natural selection?

Answer 1

Charles Darwin was able to offer a large amount of evidence for his theory of evolution by natural selection because of his extensive research and observations. He spent five years on the HMS Beagle, traveling around the world and studying the different species of plants and animals he encountered. He also conducted experiments and collected specimens from around the world. He also studied the fossil record and the geographical distribution of species. All of this evidence helped him to develop his theory of evolution by natural selection.
