Evolution or Creation Theory
or
Man and surface culture
The latter would seem to be the title of a work devoted to
agricultural produces. Just that here it does not speak of
"crops" but of "culture."
The reference is obviously to the superficiality that often
characterises the approach of human sensibility towards things
which regard the world, which is, as said, superficial.
This superficiality does not often allow us to fully see the
aspects that surround us or, at least, relegates us to the
simple role of men who are satisfied by what we learn or what we
are told.
But science, just like faith, cannot grow (inside and outside of
us) if it does not continually doubt in order to verify, mature,
and assimilate better.
Returning therefore to the main title, we immediately have to
report a serious scientific gap that has distinguished itself,
above all in the last century, not so much as the result of a
free and unconditioned Enlightenment, but, it seems to us, as
the result of an exaggerated trust in the theory of evolution
which in some respects has led to the extreme consequences of
being scientifically (and mathematically) impossible.
In order to enter into the heart of the matter, not everyone
perhaps knows that the debate between supporters of the theories
of creation and of evolution, (which marked the beginning of the
scientific model) has never been resolved and which, above all
today, thanks to ever greater scientific knowledge and
discoveries, is more open than ever.
Above all, the debate between scientific affirmations and
theories is wide open.
In fact the discussion on the origins of life is not science in
a narrow sense. This is due to the fact that the origins cannot
be submitted to experimental verifications. When life began, or
when the different types of organisms started to exist,
scientific observatories did not exist. Besides these events no
longer happen in the present world. Therefore, from a scientific
point of view, the solution to the problem of the origins is
impossible. The philosophical point of view of modern biologists
with regards to the origins can be reduced to two: the doctrine
of evolution and the doctrine of creation. The first affirm that
life and its various forms have gradually appeared because of
natural processes over long periods of time. The second believe
that life in its principal forms instantly had its origin
through the creative actions of the Creator himself.
Both the evolutionists and the creationists agree on the facts
of present-day biology. The disagreement concerns the
interpretation of the origins and the meanings of these facts.
Scientists use models to explain natural phenomena. Every
proposed model is appraised according to its efficiency: how are
the available data inserted in the model proposed for explaining
a specific phenomenon?
In this way, even the two principal points of view which regard
the origins can be summarized in an "evolutionist model" and a
"creationist model". The model that better suits the available
data will also be the most efficient and reasonable.
At this point it is useful to remember that some researchers
have proposed a model that can be found half way between those
mentioned above, accepting both the theories of evolution and
creation. This position can be better understood after an
evaluation of the two basic models. In any case, many
scientists, both evolutionists and creationists, refuse this
idea.
The coherent evolutionist affirms that if enough evolutionary
processes exist to explain the data that we observe in nature -
and he believes that they do exist - it is not then necessary to
resort to creative processes. The creationist believes that it
is necessary to postulate creative actions to explain the data
coming from nature, and holds, therefore, that evolution is not
necessary.
The two models are not compatible, if not at a very superficial
level, since they diametrically represent two opposite points of
view on the origins.
1. The evolutionist model
According to the evolutionist model, the observable natural
processes are enough to explain the origins of the universe and
all the transformations necessary to produce the immense variety
and present complexity. Despite occasional regressions or
limited failures, the general effect of the evolutionary
processes has been that of diversification and of an increase in
complexity stemming from primordial simplicity.
According to this model, in fact, all living things are allied
by common descent (genealogical roots) and are slowly
transformed. Therefore it is possible to make certain
predictions that can serve for judging the validity of the
model:
- We should be able to observe innumerable similarities among
living beings, going from the simplest species to the most
complex, without there being discontinuity.
- The processes that have given origin to all the beings should,
if observed in the present, produce new beings and an ever
increasing complexity of species.
- If it were possible to decipher the history of the Earth, one
should be able to observe that the variety and the complexity of
living beings increasing through time.
Observing the data at our disposition we notice that the
predictions mentioned above are verified only in part. Comparing
different organisms we observe that there are indeed a lot of
similarities between them: for example in the anatomy, in the
embryonic development, in the biochemistry, in the genetics,
etcetera.
The data at our disposal do not show a continuity of
similarities without interruptions between different species.
There are - it is true - conjectures to explain the existence of
the numerous discontinuities, but these can not be
scientifically experimented, therefore they do not offer a
reasonable explanation for this evident lack in the evolutionist
model.
The study of various biological processes confirms the forecast
that many changes currently happen also in living organisms. It
is, for example, possible to produce new living species through
the mechanisms of hybridization (cross species), through induced
mutations and through selection. These phenomena can happen in
natural or artificial ways.
Again, however, the evidence at our disposal is not completely
convincing, since these changes are not transformations which
tend to increase the level of organization, as forecasts would
suggest. They can be divided into two groups:
- variations which are relatively limited and simply lead to new
variations of existing species;
- mutations which derive from casual changes in the DNA of the
germinal cells, with consequent diminution of the organization
of the individual, and never with the result of new physical
characteristics.
These two phenomena can be better used for sustaining the
principle of conservation and decay rather than that of the
formation of new species and the increase in complexity, as the
evolutionist model proposes.
Many evolutionist scientists affirm that through the study of
the small variations an understanding of the dynamics of
greater transformations can be reached,
even if the observations made up until today do not sustain
this theory .
The prediction that the complexity of organisms is increased
during the geological eras seems at first confirmed by fossils.
Palaeontology undoubtedly offers the greatest evidence in
support of evolution. However, such evidence is seriously
weakened through a circular way of reasoning: the geological
scale of eras is based on the hypothesis that evolution has
taken place.
The dating of geological formations is primarily determined by
the "fossils index" that they contain. In order to have exact
suppositions, the dating done through the use of radioactive
minerals is always corrected through palaeontological
criterions. In addition, there are a lot of places in which
fossils coming from different geological eras are found in the
same layers, just as there are sediments in which "old" fossils
are found above formations containing "young" fossils.
It has been seen that the greater part of the layers containing
fossils of great plants or animals must have been deposited very
quickly, perhaps even catastrophically, otherwise they would not
have been preserved. The study of the fossils does not
necessarily show that a slow and uniform evolution has happened
during the geological eras, but rather suggests that there has
been a sequence of catastrophic events at a planetary level.
It is true that some data can be interpreted according to an
evolutionist picture. This interpretation is, however, not at
all conclusive. Certainly everyone is free to believe through an
act of faith, but in this way we have to honestly admit that it
is no longer possible to call evolution "science".
2. The creationist model
The principal postulation of this model is that in the past
there has been a period in which all
things were created - that is to say, formed from nothing -
through the power of the Creator. All the physical and
biological entities were made perfectly, each with its specific
form and function.
The living biological forms in the present are preserved rather
than
created. The actual natural processes are therefore
conservative processes that serve to maintain the stability of
the living forms, and are not evolutionary processes.
This does not mean that variations or changes are not possible.
On the contrary: an important postulation of the creationist
model is that during the creation, the basic entities
contained an enormous potential of variability. However,
the action of these mutations will always be limited to within
the entities that were initially created. In the biological
field, for example, new varieties can quickly appear but no new
basic type.
According to the biblical version of the creationist model,
shortly after the period of the creation the universal principle
of
decay was introduced. In the end there was a cataclysmic
flood in all the world that radically changed the face of
the earth and the speed of many natural processes.
The characteristics of the creationist model mentioned above are
confirmed by most natural phenomena that we can observe, showing
therefore the validity of the creationist model at a scientific
level. We have, however, to remember that, with scientific
methods, any model of the origins can never be completely verified.
The two basic scientific principles, which
are also those that are most firmly established, are the
first and second law of thermodynamics. These two laws are
applied to all scientific disciplines without exception. They
can be interpreted
as predictions confirmed by the creationist model.
The first law (conservation of mass-energy) sustains the
prediction that, beginning from the moment in which the universe
was created and completed, nothing more is created or destroyed:
everything is preserved.
The second law of
thermodynamics (that of increasing entropy) is essentially also
a confirmation of the universal law of decay and death
postulated by the biblical version of the creationist model.
The stability of the biological species (the basic entities)
is sustained without exception by all the data observed
in biology. Therefore, a population of Biston betularia butterflies can change colour because of the
content of soot in the atmosphere and natural selection, but it will still remain a population of
Biston betularia butterflies. Thousands of consecutive
generations of
Drosophila melanogaster
can be exposed to radiation and other mutational agents,
producing an ample range of mutants, but they will still remain
Drosophila melanogasters.
In the creationist model ample discontinuities are also foreseen
among the basic species, since every species has been created
for a specific purpose, therefore it will have structures which
have been purposefully planned for that purpose. On the other
hand, a lot of similarities are also foreseen,
since it is to be expected that when similar functions must
be performed in similar environments, even by different species,
similar structures will be planned.
With regards to palaeontology, it is known that the
discontinuities among different species exist both in the
fossils found and in the present biological world. There are a
lot of extinct species, as there are extinct varieties (found in
fossils) of species which are currently still in existence. But
none of these can be considered as a transitional link between
two different biological entities.
Conclusive considerations
There are therefore two possible models to explain the origins:
the evolutionist model and the creationist model. Both have
important philosophical consequences and both cannot be proven
scientifically. On the other hand, both can be used as frames of
reference for developing forecasts on natural phenomena.
The creationist model offers an interpretative picture that is
at least as satisfactory as the evolutionist model. The two laws
of thermodynamics, the
apparent stability of the
basic “species”, the presence of discontinuity between the
species and the deteriorating nature of
mutations, are all
factors which better refer to a creationist model rather than to
an evolutionist one.
In addition, the
principles of
physics, chemistry and other physical sciences are easily
recognizable in a creationist frame rather than in an
evolutionist one.
Despite this, the majority of
modern biologists prefer to adopt the evolutionist point of view
for the origins as an explanation for the facts of
biology. In effect, many are so confident of this position
that they affirm that evolution is a scientific fact.
But this affirmation has never been proven, nor can it ever be.
There are today also a notable number of biologists and other
scientists convinced that the creationist model is more
reasonable and satisfactory in order to explain the origins.
Many of these men and women belong to the Creation Research
Society, an organization that brings together around 500
scientists who have at least a doctorate in a scientific
discipline. The society devotes itself to research and the
publication of
information which supports the creationist model.
The preponderant number of evolutionists in the scientific and
educational world has however conducted to a monopoly of
evolutionist opinions in modern text books. For this reason, it
is necessary to have a way of teaching which can simply
introduce the biological facts without any preconceptions with
regards to their interpretation, or a teaching in which the two
contrasting models are introduced
in order to be able interpret the facts. The present
article filler simply contributions (present also on Internet)
of the debate on the two theories, without to enter in personal
appraisals. Southernland does not have one official position on
the argument.
