"Nothing in Biology Makes Sense Except in the Light of Evolution" is a 1973 essay by the evolutionary biologist Theodosius Dobzhansky, criticising anti-evolution creationism and espousing theistic evolution. The essay was first published in American Biology Teacher in 1973.Dobzhansky first used the title statement, in a slight variation, in a 1964 presidential address to the American Society of Zoologists, "Biology, Molecular and Organismic", to assert the importance of organismic biology in response to the challenge of the rising field of molecular biology. The term "light of evolution"—or sub specie evolutionis—had been used earlier by the Jesuit priest and paleontologist Pierre Teilhard de Chardin and then by the biologist Julian Huxley.
