CHARLES DARWIN AND THE ORIGIN OF SPECIES<br />
Given the impact of Darwin’s theory, De Vries could have added<br />
another line: The origin of species is the subject of philosophical<br />
investigation.<br />
Science beyond Darwin<br />
The naturalistic approach to knowledge has had a significant<br />
impact on the development of human society. Investigating natural<br />
phenomena without reference to the supernatural has led to<br />
advances in science and technology that were inconceivable before<br />
the Modern Age. What person in Medieval Europe or Early Ming<br />
China would have thought it possible for humans to travel faster<br />
than the speed of sound or to walk on the moon?<br />
The ideas in The Origin of Species were an important component<br />
of the naturalistic revolution in the biological sciences: artificial insemination,<br />
Pre-implantation Genetic Diagnosis (PGD), cloning, the mapping<br />
of the human genome, genetically modified crops, and the use of<br />
stem cells—none of these developments would be possible without the<br />
foundation of the evolutionary theory of the origin of life.<br />
Furthermore, the naturalistic revolution in the sciences, particularly<br />
biology, shows no sign of abating. The quest to find which<br />
genes make a person more susceptible to cancer, for example, seems<br />
far too important to discontinue. Knowing about the origins of life<br />
has prompted the human race’s desire to cure, fix, or ameliorate the<br />
problems and difficulties of life. Humans living before Darwin and<br />
before 1500 wanted to prolong life or make it more comfortable, but<br />
the scientific tools available since the publication of The Origin of<br />
Species are far greater.<br />
The more important question concerning the theory of evolution<br />
may be what should humankind do with the power it seems to<br />
have over nature (rather than whether or not the theory of evolution<br />
is true). The potential problems are moral rather than scientific.<br />
Much seems possible. Even if the impossible is achievable, however,<br />
does humankind want to aim that high? It may be possible to produce<br />
‘‘designer babies’’ using PGD techniques, but is that a good<br />
idea? (Most people today find the ideas associated with the eugenics<br />
movement of the early twentieth century repulsive: making ‘‘designer<br />
babies’’ seems eerily similar.) Is it ethically sound to genetically modify<br />
food even if the process seems safe? Would humankind diminish<br />
or fundamentally alter its humanity if the advances derived from<br />
knowledge about the origins of life were used in these particular<br />
ways? What exactly is the place of humankind in the world and the
