Dobzhansky on evolution theory

“Let me try to make crystal clear what is established beyond reasonable doubt, and what needs further study, about evolution. Evolution as a process that has always gone on in the history of the earth can be doubted only by those who are ignorant of the evidence or are resistant to evidence, owing to emotional blocks or to plain bigotry. By contrast, the mechanisms that bring evolution about certainly need study and clarification. There are no alternatives to evolution as history that can withstand critical examination. Yet we are constantly learning new and important facts about evolutionary mechanisms.”

Theodosius Dobzhansky, “Nothing in Biology Makes Sense Except in the Light of Evolution,” American Biology Teacher vol. 35 (March 1973); reprinted in Evolution versus Creationism, J. Peter Zetterberg, ed., ORYX Press, Phoenix, Arizona, 1983
