Better evidence, especially from genetics. When Charles Darwin first proposed the theory of evolution by natural selection his mechanism of heredity was dead wrong. He posited a blending type of heredity. When Gregor Mendel's work was rediscovered in about 1900 particulate inheritance was brought to the forefront of evolutionary thinking and the synthesis of the 1930's and '40's cooperated this thinking with Darwinian though to give us modern evolutionary theory.
