creationism<br />
explained these observations by appealing to epicycles, which<br />
are smaller revolutions within the larger revolution <strong>of</strong> the<br />
planets around the Earth. Copernicus realized that the calculations<br />
were much simpler if one assumed that the planets were<br />
circling the Sun, not the Earth. (Interestingly, Copernicus also<br />
had to appeal to epicycles, since he assumed planetary motions<br />
were circular. Physicist and astronomer Sir Isaac Newton was<br />
later to demonstrate that planetary orbits were elliptical.)<br />
Copernicus feared that such a view might be considered<br />
heretical. When he published his views in 1514, it was<br />
in a handwritten treatise (Little Commentary) circulated only<br />
among his friends. He stated basic axioms which became the<br />
basis <strong>of</strong> his major book, De Revolutionibus Orbium Coelestium<br />
(On the revolutions <strong>of</strong> the heavenly orbs), which he<br />
began writing the following year. Among the axioms were<br />
that the Earth is not the center <strong>of</strong> the universe; the distance<br />
from the Earth to the Sun is miniscule compared with its distance<br />
to the stars; the rotation <strong>of</strong> the Earth accounts for the<br />
apparent movement <strong>of</strong> stars across the sky each night; the revolution<br />
<strong>of</strong> the Earth accounts for the apparent movements <strong>of</strong><br />
the Sun and stars over the course <strong>of</strong> a year; and the apparent<br />
backward motion <strong>of</strong> the planets was caused by the movement<br />
<strong>of</strong> the observer, on the Earth. All <strong>of</strong> these things are understood<br />
by educated people today, but in Copernicus’s time the<br />
very concept that “the Earth moves” was revolutionary.<br />
Copernicus’s progress on his book was slow, partly<br />
because he hesitated to announce his theories, and partly<br />
because he spent a lot <strong>of</strong> time as a government administrator,<br />
attempting to prevent war between Poland and the Germans<br />
and then dealing with the consequences <strong>of</strong> war. The book was<br />
not published until immediately before his death. Copernicus<br />
left his manuscript with a Lutheran theologian, who without<br />
the author’s knowledge removed the preface and substituted his<br />
own, in which he claimed the work was not intended as literal<br />
truth but just as a simpler way <strong>of</strong> doing astronomical calculations.<br />
Although many scholars were and are appalled at this<br />
substitution, it may have prevented Copernicus’s work from<br />
being condemned outright. Had Copernicus lived to see what<br />
happened to other astronomers such as Galileo Galilei, who<br />
defended the view that the Earth moved around the Sun, he<br />
might have been even more hesitant about publishing his work.<br />
Copernicus’s revelation that the Earth revolved around<br />
the Sun is considered by many historians to be the decisive<br />
work that broke the unscientific medieval view <strong>of</strong> the world<br />
and opened the way for scientific research. Copernicus’s<br />
dedication to observation over theology made all subsequent<br />
scientific work, including the development <strong>of</strong> evolutionary<br />
science, possible. He died on May 24, 1543.<br />

creationism Creationism is the belief that evolutionary science<br />
is wrong and that the history <strong>of</strong> the Earth and life can<br />
be explained only by numerous miracles. There is a range <strong>of</strong><br />
beliefs ranging from the most extreme forms <strong>of</strong> creationism<br />
to evolutionary science:<br />
• Young-Earth creationists insist that the universe and all its<br />
components were created recently by God and the entire<br />
fossil record was produced by a single flood, the Deluge <strong>of</strong><br />
Noah.<br />
• Old-Earth creationists believe that the Earth is old but that<br />
life-forms were created miraculously throughout the history<br />
<strong>of</strong> the Earth.<br />
• Theistic evolutionists accept the general outline <strong>of</strong> the<br />
evolutionary history <strong>of</strong> life on Earth but believe that God<br />
intervened miraculously, perhaps subtly, in the evolutionary<br />
process.<br />
• Deists believe that God set the natural laws in motion at<br />
the beginning and has not physically acted upon the universe<br />
since that time. Deism, in terms <strong>of</strong> scientific evidence,<br />
cannot be distinguished from evolutionary science, except<br />
perhaps in cosmology (see universe, origin <strong>of</strong>).<br />
In the review that follows, the young-Earth definition is<br />
used. Creationism consists <strong>of</strong> a creationist theology, in which<br />
the Christian Bible is interpreted literalistically, and “creation<br />
science,” in which scientific information is presented to support<br />
those literalistic Bible interpretations.<br />
Although many evolutionary scientists believe in God<br />
(see essay, “Can an <strong>Evolution</strong>ary Scientist Be Religious?”),<br />
evolutionary science operates under the assumption that God,<br />
if God exists, has not influenced the processes that are being<br />
studied.<br />
The fundamental assumption <strong>of</strong> creationists is that creationism<br />
is the only alternative to a completely nontheistic<br />
evolutionary philosophy; most consider creationism to be<br />
the only alternative to atheism. For this reason, creationists<br />
spend a great deal <strong>of</strong> time attacking aspects, sometimes<br />
even details, <strong>of</strong> evolutionary science. They imply, but seldom<br />
directly state, that if evolutionary science has even one flaw,<br />
then any reasonable person must accept all <strong>of</strong> the tenets <strong>of</strong><br />
biblical literalism, from the six days <strong>of</strong> Genesis to the Flood<br />
<strong>of</strong> Noah. Most religious people, not only in mainstream but<br />
also in conservative Christian churches, accept at least some<br />
aspects <strong>of</strong> evolutionary science and have done so for more<br />
than a century (see “American Scientific Affiliation” and the<br />
book by Matsumura in Further <strong>Reading</strong>). Many prominent<br />
evolutionists have been religious (see Gray, Asa; Teilhard<br />
de Chardin, Pierre; Dobzhansky, Theodosius). Despite<br />
this, creationists attempt to increase their support base by<br />
presenting themselves as the only alternative to atheism.<br />
There is a limited amount <strong>of</strong> diversity in creationist<br />
beliefs. For example, many creationists do not believe that<br />
God created each species, as defined by modern science, separately;<br />
they believe instead that God created separate “kinds,”<br />
an undefined category that may refer to species, genus, family,<br />
or other level <strong>of</strong> taxonomic classification (see Linnaean<br />
system). Creationists have even invented a new taxonomic
