The overal point of the article cited being Darwin Evolution is about as useful in a practical sense as a fifth person on a double date.<quoted text>Dobzhansky's quote doesn't say that science can't be done without knowing, understanding or even need the theory of evolution. It simply states that evolution brings sense to the many facets of biology that we have discovered. It is the basis of modern biology, because it explains what is discovered, and can be used to guide further inquiry and discovery. It is not some essential parameter without which experiments cannot be conducted and research pursued.
Theodosius Dobzhansky's dictum that 'nothing in biology makes sense except in the light of evolution,' most can conduct their work quite happily without particular reference to evolutionary ideas," A.S. Wilkins, editor of the journal BioEssays, wrote in 2000.1 "Evolution would appear to be the indispensable unifying idea and, at the same time, a highly superfluous one."
I would tend to agree. Certainly, my own research with antibiotics during World War II received no guidance from insights provided by Darwinian evolution. Nor did Alexander Fleming's discovery of bacterial inhibition by penicillin. I recently asked more than 70 eminent researchers if they would have done their work differently if they had thought Darwin's theory was wrong. The responses were all the same: No.
I also examined the outstanding biodiscoveries of the past century: the discovery of the double helix; the characterization of the ribosome; the mapping of genomes; research on medications and drug reactions; improvements in food production and sanitation; the development of new surgeries; and others. I even queried biologists working in areas where one would expect the Darwinian paradigm to have most benefited research, such as the emergence of resistance to antibiotics and pesticides. Here, as elsewhere, I found that Darwin's theory had provided no discernible guidance, but was brought in, after the breakthroughs, as an interesting narrative gloss.
