The above examples are just a sample of the benefits to society that flow directly from the creative power of Charles Darwin’s theory of evolution by means of natural selection (for more about Darwin’s legacy, refer to Charles Darwin: The concise story of an extraordinary man19). The publication of On the Origin of Species, on 24 November 1859, precipitated one of those rare events in the history of science—a paradigm shift. Philosopher Thomas Kuhn used this term to refer to the replacement of one world view by another.20 Examples of a paradigm shift in science include the replacement of the earth-centered Ptolemaic system by the sun-centered Copernican system; and the replacement of Newtonian physics by relativity and quantum physics. The paradigm shift instigated by Darwin’s legacy has made obvious the superiority of this scientific method as a means of understanding the world around us.

Evolutionary thinking explains the arms race waged by pathogens and hosts that prevents either from being eliminated completely. Darwinian reasoning easily explains the development of antibiotic-resistant bacteria through the flagrant overuse of antibiotics. A drug kills the susceptible bacteria leaving bacteria with a pre-existing resistant mutation to build up the next generation. Then when you actually need the antibiotic for a bacterial infection, patients and doctors find that the drug is ineffective. This is evolution, pure and simple.

Darwinian or evolutionary medicine6 explains how some disease symptoms, such as fever, may be a response favored by natural selection as a defense against pathogens. Some genetic diseases such as sickle cell anemia may allow differential survival of its victims in malarial zones—a phenomenon called a balanced polymorphism (genetic variation, e.g., blood types).4 This results in a deleterious gene (sickle cell) being maintained at a relatively high frequency in a population, even though it can be lethal in a double dose (homozygous), because it protects its carriers against malaria when present in a single dose (heterozygous).

Darwin’s explanation of evolution via natural selection is the basis of all of biology and its applied sub-disciplines of medicine, agriculture, and biotechnology. No other biologist in the history of our species has had an impact of this magnitude. In the words of the eminent geneticist Theodosius Dobzhansky, “Nothing in biology makes sense except in the light of evolution.”5 The paradigm shift from creation to evolution has moved intellectual endeavors from an untestable beliefs to a rational understanding that flows from the scientific method. This, in turn, has allowed a vast array of advances in knowledge.

Darwin borrowed the expression “survival of the fittest” from economist Herbert Spencer (1820-1903). Evolutionary fitness means reproductive fitness. In modern terms, the fittest is the one who gets the most genes into the next generation—not necessarily the biggest or strongest individual.
