Nothing in Biology Makes Sense Except in the Light of Evolution.
These are the words of Theodosius Dobzhansky, one of the founding fathers of the quantitative study of evolution. He wrote an essay about why evolution is so important, and also discussed how he reconciled his Christian faith and the scientific theory of evolution.
The evidence for evolution is overwhelming, if you accept scientific reasoning. There is mathematically no way that evolution could not occur if just three things are true: more creatures are born than get to reproduce; they can vary in new ways; and that these variations are inherited. The first is trivially true as any look in the garden will show, as is the third: for example people take after their parents. The second is more difficult because although all individuals do vary, they mostly do so in an uncreative way by mixing up the traits of their parents. But it does occur: mutations are the source of these creative changes and it has been demonstrated many times that novel abilities (at the microscopic level) can arise.
There is a resurgence recently, particularly in America, to doubt evolution for religious reasons. However, this doesn’t have anything to do with the religion per se, but is a cultural phenomenon. Dobzhansky quite powerfully argues that to deny evolution on religious grounds is verging on blasphemous: it implies that the creator deliberately set out to deceive us. We have the ability to reason about the origins of fossils, or of finches in the Galapogos, and explain why they are there. There is no hole in the theory that has yet been found. To believe that this is some elaborate charade is absurd.
Dobzhansky believed in creation: that god created the world such that we would be here today. It is a matter of philosophy whether this happened by divine will or by chance. It is beyond science to answer the question of whether we were “created” in this way, or arose by chance, because there is only one universe from which to draw evidence. But in this Universe, we have surely evolved, and this is not evidencef or or against God in the slightest.
