EVOLUTIONARY TALL TALES FROM THE BBC
-II-
The second
installment of the documentary, The Human Body, again consisted
of evolutionist propaganda devoid of any scientific credibility. The
errors in the documentary prepared by BBC are scientifically explained
below.
BBC's Tall Tale about "Fish Gills
Becoming Human Ears"
The BBC documentary maintained that human
beings and fish had a common ancestor, and that traces can still be
found in the human body which prove this. According to BBC, the human
ear is one example of such a trace, and its origin is to be found
in the bones beside the gills in the fish, with which we share (!)
a common ancestor.
This BBC claim rests on the theory of
"recapitulation," which has long since been discredited in the scientific
literature. Since this matter has already been dealt with in the article
"Evolutionary Tall Tales from BBC - I," there is no need to repeat
it here.
The subject to be considered here is that
the human ear possesses such a complex structure that it could never
have evolved from a fish bone.
The Human Ear Possesses Irreducible
Complexity
The significance of the irreducible complexity
possessed by the human ear is this: The human ear is made up of several
separate parts all coming together, and we are able to hear as a result
of all these parts' working in harmony together. If one of these components
is deficient, then we either become deaf or else our sense of hearing
suffers serious damage. It is impossible for an organ possessing irreducible
complexity to develop by stages, by chance, in a process of evolution.
A brief résumé of how hearing actually takes place will enable this
fact to be more clearly understood.
As is commonly
known, the hearing process begins with vibrations in the air. These
vibrations are enhanced in the external ear by about 17 decibels.1
a) The three separate regions of the ear,
the outer ear, middle ear and inner ear.
b) In this picture, which shows the middle and inner ear under
magnification, can be seen the eardrum, three ossicles and the
oval window connecting them. Sound waves striking the eardrum
cause these ossicles to vibrate, thus causing the fluid in the
next structure along, the cochlea, to move.
c) There are three areas in this cross section of the cochlea.
In the middle are the organ of Corti and sound receptors.
d) This magnified diagram shows the tiny hairs in the organ
of Corti. It is thanks to these hairs that sound signals reach
the brain. |
Sound intensified in this way enters
the external auditory canal. This is the passageway leading from the
external ear to the eardrum. One interesting feature of the auditory
canal, which is some three and a half centimeters long, is the wax
it constantly secretes. This liquid contains an antiseptic property
which keeps bacteria and insects out. Furthermore, the cells on the
surface of the auditory canal are aligned in a spiral form directed
towards the outside, so that the wax always flows towards the outside
of the ear as it is secreted.
The vibrations from an external noise
cause the liquid in the inner ear to vibrate. The movement of
this liquid sets the tiny hairs on the inner walls of the cochlea,
shown in this picture, in motion. The movements of these hairs
allow the sound of a violin, a television newsreader's voice
or the wailing of a cat in the street to reach the brain in
the form of electrical signals. Thanks to these flawless structures
we are able to distinguish between millions of different sounds.
Science has still not unravelled all the technical details of
this system, which has been functioning flawlessly ever since
the first human being. Here, we need to see the immaculate art
of God, our Creator, and give thanks for the blessings He has
bestowed upon us. |
Sound vibrations that pass down the auditory
canal in this way reach the eardrum. This membrane is so sensitive
that it can even perceive vibrations on the molecular level. Thanks
to the exquisite sensitivity of the eardrum, you can easily hear somebody
whispering from yards away. Another extraordinary feature of the eardrum
is that after receiving a vibration it returns to its normal state.
Calculations have revealed that, after perceiving the tiniest vibrations,
the eardrum becomes motionless again within up to four thousandths
of a second. If it did not become motionless again so quickly, every
sound we hear would echo in our ears.
The eardrum amplifies the vibrations
that come to it, and sends them on to the middle ear region. Here,
there are three bones in an extremely sensitive equilibrium with each
other. These three bones are known as the hammer, the anvil, and the
stirrup; their function is to amplify the vibrations that reach them
from the eardrum.
But the middle ear also possesses a kind
of "buffer," to reduce exceedingly high levels of sound. This feature
is provided by two of the body's smallest muscles, which control the
hammer, anvil, and stirrup bones. These muscles enable exceptionally
loud noises to be reduced before they reach the inner ear. Thanks
to this mechanism, we hear sounds that are loud enough to shock the
system at a reduced volume. These muscles are involuntary, and come
into operation automatically.
The middle ear, which possesses such
a flawless design, needs to maintain an important equilibrium. The
air pressure inside the middle ear has to be the same as that beyond
the eardrum-in other words, the same as the surrounding atmospheric
air pressure. But this balance has been thought of, and a canal between
the middle ear and the outside world allowing an exchange of air has
been built in. This canal is the Eustachian tube, a hollow tube running
from the inner ear to the oral cavity.
The process whereby these mechanical
motions begin to be turned into sound begins in the area known as
the inner ear. In the inner ear is the cochlea, a spiral-shaped organ
filled with liquid. The cochlea is linked to the stirrup bone by a
membrane. By this connection, the mechanical vibrations in the middle
ear are sent on to the liquid in the cochlea.
The vibrations which reach the liquid
in the cochlea set up wave effects in it. The inner walls of the cochlea
are lined with small hair-like structures, called stereocilia, which
are affected by this wave effect. These tiny hairs move strictly in
accordance with the motion of the liquid. If a loud noise is emitted,
then more hairs bend in a more powerful way. Every different frequency
in the outside world sets up different effects in the hairs.
But what is the meaning of this movement
of the hairs? What can the movement of the tiny hairs in the cochlea
in the inner ear have to do with listening to a concert of classical
music, recognizing a friend's voice, hearing the sound of a car, or
distinguishing the millions of other kinds of sounds?
Not
even sound systems with the very highest technology can offer
us the sound quality we enjoy when listening to a piece of music.
The flesh and blood audio system in our ears is flawless. Scientists
have still not fully understood this extraordinary system. Believing
that such perfection could have come about by chance takes one
no further than believing in fairy stories.
|
The answer is most interesting, and once
more reveals the complexity of the design in the ear. Each of the
tiny hairs covering the inner walls of the cochlea is actually a mechanism
which lies on top of 16,000 cells. When these hairs sense a vibration,
they move and push each other, just like dominos. This motion opens
channels in the membranes of the cells lying beneath the hairs. And
this allows the inflow of ions into the cells. When the hairs move
in the opposite direction, these channels close again. Thus, this
constant motion of the hairs causes constant changes in the chemical
balance within the underlying cells, which in turn enables them to
produce electrical signals. These electrical signals are forwarded
to the brain by nerves, and the brain then processes them, turning
them into sound.
Science has not been able to explain
all the technical details of this system. While producing these electrical
signals, the cells in the inner ear also manage to transmit the frequencies,
strengths, and rhythms coming from the outside. This is such a complicated
process that science has so far been unable to determine whether the
frequency-distinguishing system takes place in the inner ear or in
the brain.
Everything we have examined so far has
shown us that the ear possesses an extraordinary design. On closer
examination, it becomes evident that this design is irreducibly complex,
since, in order for hearing to happen, it is necessary for all the
component parts of the auditory system to be present and in complete
working order.
Take away any one of these parts-for
instance, the hammer bone in the middle ear-or damage its structure,
and you will no longer be able to hear anything. In order for you
to hear, such different elements as the eardrum, the hammer, anvil,
and stirrup bones, the inner ear membrane, the cochlea, the liquid
inside the cochlea, the tiny hairs that transmit the vibrations from
the liquid to the underlying sensory cells, the sensory cells themselves,
the nerve network running from them to the brain, and the hearing
center in the brain-all of these parts must exist in complete working
order. The system cannot develop "by stages," because the intermediate
stages would serve no purpose.
The claim that an organ as complex as the
ear should have been constructed in stages by an unconscious process
dependent solely on random chance, such as evolution, is both unscientific
and irrational. BBC must be aware of this impossibility, since it frequently
repeats that this is a miracle that is very difficult to believe, and
says: "Evolution shapes our bodies. It is hard to believe that it could
bring all this about."
BBC's Time Error
One of the claims frequently repeated
on BBC's documentary is that minute changes combined over time to
bring about major transformations, and that this is how evolution,
which looks to be impossible at first sight, actually happens.
At the root of this argument, which is
one of BBC's and other evolutionists' fundamental refuges, lies the
assumption that time is a force that can do the impossible. According
to this view, it is impossible for a chemical mixture to randomly
produce amino acids, proteins, DNA, RNA, and other cell components,
and thus a living cell-or, alternatively, for a reptile to turn into
a bird-in a short space of time. As time goes on, however, for instance
over millions of years, the impossible suddenly becomes possible.
Evolutionists describe this time factor
as "the accumulation of advantageous coincidences." In other words,
a structure will gain a positive feature by means of an advantageous
coincidence, another such coincidence will be added to it a few thousand
years later, yet another one will happen a few thousand years after
that, and at the end, over the course of millions of years, these
advantageous coincidences will combine to bring about a major and
positive transformation.
Many people may accept this logic without
examining it too closely. Yet, it contains a simple but fundamental
error. This lies in the concept of "advantageous coincidences being
added on to one another." The fact is that there is no mechanism in
nature that might be expected to select advantageous coincidences
and hold on to them in order to add them to one another.
We can clarify what
this means with an example that evolutionists also resort to. Some
scientists say that the possibility of a protein being synthesized
by chance is "less than the probability of a monkey typing out the
history of mankind without any mistakes."2
According to Ali Demirsoy, a Turkish biologist,
the probability of a coincidental formation of cytochrome-C,
an essential protein for life, is "as unlikely as the possibility
of a monkey writing the history of humanity on a typewriter
without making any mistakes." There is no doubt that to accept
such a possibility is actually to reject the basic principles
of reason and common sense. |
Yet evolutionists still hide behind the
idea of time in the face of such inconsistencies. This is the kind
of claim they make: "Every time the monkey touches the keyboard it
has a one-in-26 chance of hitting the right key. Once it has pressed
the right key, this is chosen as the right letter by natural selection.
The errors it will commit over the next letter are again chosen by
natural selection. In this way, over a period lasting millions of
years, a monkey can indeed write a history of mankind."
This is the logic that underlies all
the time-related claims made by evolutionists.
The fact is, however, that, as we have
already stated, there is a simple error in this position: There is
no mechanism in nature to identify and select which of the keys pressed
by the monkey is the right one! There is no consciousness which can
say, "OK. This letter is right, let's hold on to it and move on to
the next stage."
Moreover, neither is there any monkey
to touch the keys in nature. That requires consciousness. The evolutionists'
argument must be that natural effects such as wind, rain, and earthquakes
cause the typewriter keys to move.
When we examine the scenario that the
cell and all living structures have come about by chance in this more
realistic light, we see that we are actually dealing with nonsense.
The idea that a single cell emerged by chance-that is, that the millions
of tiny coincidences that form the building blocks of the cell occurred
at random in an ordered sequence-can be compared to the claim that
a giant city emerging solely by natural means, with no constructive
force behind it. Rain, earth, and heat would have to combine by chance
to form millions of bricks. Then these bricks would have to line up
side by side and one on top of the other, under the effects of such
things as wind, flood, and earthquake, to make houses, roads, and
pavements, as a result of which a whole giant city would eventually
emerge by chance.
If someone suggested such a thing to
you, you would seriously doubt that person's sanity. Would anything
change if that person then suggested that this happened not in a short
space of time but over millions of years?
Of course not. Nonsense is nonsense, and
the impossible is impossible, no matter how long a time it is allowed
for it. That is why the BBC's invocation of "time" as a savior does
not actually validate its claims.
Conclusion
There are unscientific claims and evolutionist
propaganda in the BBC documentary. We hope that those who broadcast
this documentary will have another look at its contents, will see
that no scientific evidence for the evolutionary scenarios recounted
in it like fairy tales has been put forward, and will cease showing
it.
