Q: Darwin was not the first person to talk about species changing over time. What made his work endure and come to be supported by such a large body of evidence?

Flexi Says: There are several possible reasons for this. Darwin's theory was the first of its kind which was backed by enormous amount of information gathered by the scientist and the theory was written in very appealing language. Discoveries in the field of evolutionary biology that were made after Darwin's theory were in agreement with the idea of Natural Selection and provided further evidence for the theory.
