Evolution or Creation? (In evaluating a scientific theory)
¡¡
Introduction
The
history of science is a history of conflict.
No new idea has ever been developed without challenging an old idea.
Evolution
or Creation? A question that has caused much controversy since the first
evolutionary
The
creationists claim to be creationism scientists, and creationism is said to be
scientific
What
is a Scientific Theory?
¡°Science
What exactly is considered a scientific theory? To make it simple: theory is a hypothesis that stands up to vigorous testing without being falsified. Moreover, a valid theory has to meet the following three main types of criteria. 1)logical criteria, 2)empirical criteria, and 3) historical criteria.
Theories are built to explain the mechanisms behind facts, as the gravitational theory explains the fact that the apple falls downwards. However, scientific theories themselves need to be constantly evolving. For instance, when an old theory, or part of the theory, is proven invalid through scientific testing, a new, usually more accurate theory must be built to replace it. So, are evolution and creationism scientific theories? And does the theory of evolution need to be replaced?
What
is the Theory of Evolution?
¡°The
secrets of evolution are time and death. Time
for the slow accumulations of favorable mutations, and death to make room for
new species.¡±
Common descent: All living things originated from a common ancestor.
Gradualism:
Species evolve slowly and gradually through a
long period of time, which would suggest a relatively old earth.
Multiplication
of species: The number of species increase
as new species arisen from the old.
Natural
selection: Only the ¡°fittest¡± can
survive, and the weaker are eliminated through generations.
Mutation:
Mutation works with natural selection and the
environmentally favorable mutations are
What
is the Theory of Scientific Creation?
¡°And
God made the beasts of the earth after their kind, and the cattle after their
kind, and everything that creeps on the ground after its kind; and God saw that
it was good.¡± (Genesis 1:25)
Relatively
new earth: The universe, including the
earth and all its life forms are only about 6000 to
Creator:
The universe and life are created through
supernatural powers possessed by the Christian God.
Creation:
The sudden and one creation of the universe and
life from nothing, through steps recorded in the book of Genesis.
Catastrophe:
The earth is dominated by catastrophes
created by God, such as the Noahic flood recorded in Genesis.
Are
They Logical?
I compared the two ¡°theories¡± under the three logical criteria of a valid theory. They are
a) simple, unifying idea that is logically consistent internally
b) logically falsifiable
c) limited my explicitly stated boundaries.
Referring to the evolution theory stated earlier, it is definitely simple, unifying idea that is logically consistent internally. It is also logically falsifiable, because it can be imagined to be invalid. The theory is also limited by explicitly stated boundaries: it applies explicitly to all living organisms (including ones that are extinct) that has naturally brought to life on earth. Therefore, for example, scientists would know not to look at artificial breeding for relevant observations.
Clearly,
Scientific Creationism is also a simple unifying idea, it is the simple idea of
a God¡¯s creation of everything imaginable and more, as stated in the book of
Genesis. However, whether it is
stated in a consistent, logical manner is debatable.
One can argue, that he does not interpret the Bible as literally true,
symbolic, or mythical, therefore whether creationism is logical or not really
depends on one¡¯s religious beliefs. Creationism
cannot be logically falsified, since it is stated as the simple ¡°Truth¡±. ¡°The
Are
They Empirically Verified?
Baring in mind that all scientific theories have to empirically tested, I compared evolution with scientific creationism. The empirical criteria are
a empirically testable
b) make verified predictions and/or retrodictions
c) reproducible results
Clearly,
a theory has to be empirically testable, and the tests must verify the theory in
order to give it validity. However, in the case of Scientific Creation, it cannot be,
and does not need to be tested. It cannot be tested, because it is base on
unbounded supernatural powers which is impossible to observe.
It need not to
be tested, because according to the creationists,
¡°faith¡± simply makes it a fact.
¡°The Creator¡used
On the other hand, the theory of evolution is widely tested and verified. This does not mean we have to observe the birth of a new species to prove its validity, (Neither do we have to see an actual atom to test the atomic theory) because the process is to long and slow to be observed. However, a theory can lead to predictions or retrodictions that are testable (as in the case of the atomic theory, the directions of refracted electrons in the gold foil experiment give rise to the atomic structure ). Ever since the evolution theory is first proposed, geologists, archeologists, biochemists, paleontologists and zoologists have done numerous tests that have never invalidated the theory.
Fossil record: Fossils are perhaps the most useful materials when studying evolution, they have captured billion years of the process in action. The fact that the oldest fossils appear to be the simplest best supports evolution.
Radioactive dating: The approximate age of each fossils are calculated by the usage of radio activedating, the age of the earth is also determined in the same way.
Geographic variation: the marsupials are endemic to Australia, and the pandas are endemic to China. Endemism give evidence for natural selection, as different environments give rise to different species, or variations within a species.
Biochemistry: In the early 1950s, H.C. Urey and S.L. Miller made an imitation of the earth¡¯s environment as predicted 4.6 billion years ago in a flask, several days later, organic compounds formed in the flask suggesting the first sign of life arising from inorganic substances.
A lot of misunderstanding exists regarding the verification of the evolution theory. Note a theory is proven invalid only when it is empirically falsified. Which means the remaining ¡°missing pieces of the puzzle¡± in the ¡°evolution tree¡± does not falsify it and therefore does not invalidate the theory.
Are
They Supported Historically?
Lastly, two historical criteria are considered
a) able to explain all data gathered under previous relevant theories
b) consistent with preexisting ancillary theories
To further proof the validity of the evolution theory, it also meets the historical criteria. No relevant data collected before nor after the development of the evolution theory has ever falsified the theory. Also, the theory is consistent with, even developed with the aid of the preexisting ancillary theories. Some of these ancillary theories are: sedimentation, fossilization, chemical affinity/reaction rates and so on.
Once again, Scientific Creation is proven unscientific. It cannot explain all the data collected by the evolutionists through scientific reasoning. Similarly, it is inconsistent with the preexisting ancillary theories establish through many generations in various fields. Besides sedimentation and so on, Scientific Creation also denies radioactive decay (used to date the fossils), the speed of light (used to date the universe), and the Law of Thermodynamics (stating energy cannot be created in the universe).
Conclusion
It has many times been proven that creationism is not at all scientific, though the creationists have been placing the word ¡°science¡± in front of it. However, the theory of evolution remains a valid scientific theory, which does not need to be replaced by a new one. So it is reasonable to be put amongst all the other well-established theories such as the theories of gravity and relativity. The big controversy between Evolution and Creation exists because both the evolutionists and creationists are defending their cases as if it is a scientific one.
Thoughts
What, then, is creationism? And why is it said to be scientific? Perhaps these questions can be answered in another essay. Of course, questions still remain for the details of how exactly evolution was carried out, such as how life originated or who the human ancestor was. But these questions can only involve more specialists to the studying and investigation of this field, and therefore makes the theory even more powerful. In the main while, the theory of evolution exists as the more important theory in biology, as it seeks to explain all the characteristics of living organisms, and it also keeps on making contribution to other basic sciences, such as psychology and anthropology.
