"Nothing in Biology Makes Sence Except in the Light of Evolution" is a 1973 essay written by Theodosius Dobzhansky and published in American Biology Teacher. The essay was modified from one of Dobzhansky's previous papers, "Biology, Molecular and Organismic", pusblished in 1964 in American Zoologist.
Dobzhansky was a prominent evolutionary biology and also a Russian Orthodox Christian who believed in creating a clear separation between faith and science. This paper was his last publication, a synthesis of his carreer and a strong criticism to anti-evolution creationism.
Dobzhansky took the phrase "light of evolution" from Pierre Teilhard de Chardin, a Jesuit priest and paleontologist who in his book "The Phenomenon of Man" wrote:
[Evolution] general condition to which all theories, all hypotheses, all systems must bow and which must satisfy henceforward if they are to be thinkable and true. Evolution is a light which illuminates all facts, a curve that all lines must follow. p. 219.
This paper has become a clasic in biology literature and it is a "must read" for evolutionary and population biologists.
