DNA AND SUB-SPECIES
CHANGE
Can
species change? To what degree can they change? This Is something of a
perplexing topic. It is puzzling to Me evolutionists and, to some
extent, to the creationists also. Throughout this sat of books many
questions have been discussed and the answer have shown that Creation is
the only valid explanation of the wonders In the sky above and In the
world around us. But there is a question remaining which It would be
well to address.
In
regard to species, it is clear that (1) the DNA code controls hereditary
traits, and (2) because of that code, it would be impossible for one species
to change into another one. Sub‑species variations can and do
occur, but the result is never more than a modification of the same basic
species.
In
addition, it is thought that traits passed on from one generation to
another are thought to occur only because of random hereditary gene shuffling,
in no way related to environmental effects during the life of the
individual.
Yet
certain puzzles remain. The present writer would like to suggest what may
be a new concept, yet which may provided needed solutions. Because this
present section is speculatory, it has been thought best to place it at
the back of the book, instead of at the end of chapter 15 (Species Evolution).
Three
primary explanations have been put forth for subspecies variations:
(1)
The DNA coding for a given species has limitations which cannot be
exceeded. Yet within that encircling barrier, variations can occur. These
always occur randomly, without any input from the environment. The
result is all the sub‑species variations observed everywhere on
earth. The first view (DNA) speaks of variations which cannot go beyond an
outer code barrier. R also assumes that DNA operates solely by random
operation and only through heredity. Environment has no effect on the code
arrangements produced.
(2)
Environmental effects on the organism produce all hereditary change.
There are no limitations as to what these changes may be. This view is
known as Lamarckism. h was
popularized by 'Jean de Lamarck (1744‑1829) over a century before
the DNA code was discovered. Characteristics acquired or developed
during a creature's lifetime can be passed on to its descendants.
Lamarckism teaches that hereditary changes are caused specifically and
probably solely by environmental factors.
There
are a number of flaws in this theory. Two special ones are the limitations
of the DNA code, and the fact that no traps‑species changes have
ever been known to occur.
(3)
'Alfred Russel Wallace and 'Charles Darwin suggested that random changes
occur in the organism, which they called "natural
selection." These changes were said to have produced every type
of organ and species in the works.
In
a later edition of his Origin of the Species,
Darwin forsook natural selection and changed over to Lamarckism. It
had become obvious to him that random changes would produce too many
negative results, and so few positive results that both organs and species
would rather quickly be destroyed rather than improved, if left to the
tender mercies of random variations. This total reliance on chance
actions (by so‑called "natural selection"), as the sole
means of evolution, later came to be known as "Darwinism. " Yet Darwin himself eventually abandoned the
theory.
(4)
Many later evolutionists likewise abandoned Darwinism and theorized that
random mutations‑rare and harmful though they may be‑must have
caused the changes, with only small modifications effected by natural
selection.
This
mutation (neo‑Darwinist) view imagines that it is rare, destructive
mutations which have produced all the astounding marvels we find in living
species. (Saltation, or monster mutation theory, is only a more
impossible variation of the basic mutation idea.)
Earlier
chapters detailed reasons why the Lamarckism, natural selection, and
mutation theories of evolution could not be correct. The errors in
Lamarckism are discussed in chapters 13 and 29. The error of natural
selection is covered in chapter 13. The errors basic to mutation theory
are dealt with in chapter 14, and the hopeful monster theory in chapters
14 and 29.
But
there are problems with the first view also. Consider the following:
(1)
It is very correct that, as with every code in the world, the DNA code has
limits. it only reaches out so far and can therefore include only so many
possibilities of change. All of those possibilities would be included
within a single "kind" or true species, and its modified
subspecies. Because of this, aces‑species changes cannot occur. Each
species code is so utterly complicated‑and so differentiated from
the others‑that there is no way that one code could change itself
into another one. And there is no way that any earthly
intelligence
could do it, much less chance. Evolution could never occur.
(2)
But there are factors about those modified sub‑species which do not
fit the other half of the definition: "DNA operates solely by random
operation and only through heredity. Environment has no effect on the
code arrangements produced."
A
classic example would be skin tone. The equation goes something like this:
The closer people live to the equator + the longer they live there = the
darker their skin color.
(1)
That is an environmental effect, not a hereditary one. (2) That is a
specifically-caused effect, not a random one.
The
problem is as simple as that. There is no need of accusing
someone‑including the present writer‑of being a
"Lamarckian;" what is needed is to solve the problem, wherever
it may lead us.
Yet,
after much, much thought, the present writer has developed a concept which
appears to nicely answer to the needs of the problem. You may accept it or
reject it; it matters not. At least a possible solution is available for
those who are interested.
This
view violates neither the facts of DNA as we know them, nor the species
barrier. As long as that barrier cannot be crossed, evolution cannot
occur; only sub-species changes.
Lamarckism
itself is definitely in error, for two special reasons: (1) It teaches
that in‑species changes can result from any kind of environmental
cause, and produce any kind of hereditary effect, (2) as well as
cross‑species change.
There
are thousands of men who would wish their heads into growing hair if they
could do so, but it cannot be done. There are those who have lost limbs
who would like to grow them back. Conversely, the descendants of those
who have lost limbs will not have theirs missing. Many other examples
could be cited. Lamarckism is in error.
It
is impossible to "will" new organs to grow, or push one's
thinking so hard that existing organs will decidedly change‑and
then bequeath those changes to one's offspring. Lamarck's classic
example was his suggestion that giraffes grew long necks because they kept
trying to reach up higher into the trees. Yet scientists today know that
such a changeover would be impossible. Far more than a longer neck would
be involved. Massive changes in the heart, blood vessels, as well as very
specialized organs would be required. Giraffes have highly technical
blood pumping equipment and circulatory shutoff and by‑pass
valves, which enable them to raise their heads 19 feet in the air to feed,
and then lower them to the ground to drink water.
But
why then do people living in the hottest, sunniest places of the earth
have the darkest skin? Obviously, they are the ones who needed extra
sun-screen, and, because of their location, their
environment-their skin color gradually, over the centuries changed
to a darker tone. The experts tell us that, since the United States is
hotter and sunnier than Europe, that within a few centuries the skin
color of Caucasian Americans would uniformly be darker.
We
know that Lamarckism is in error because it teaches that virtually any
kind of environmental effect will produce hereditary changes, and, ultimately,
cross-species changes.
So,
although we know that Lamarckism is an incorrect theory, yet there
definitely are instances in which creatures make sub‑species
changes because of interaction with their environment. Let us consider
some examples.
The
now-deceased Gordon R. Taylor spent a lifetime trying to figure out
this very problem. In his book, Great Evolution Mystery, this confirmed
evolutionist discussed several examples of environment‑producing
changes which were passed on via heredity to forthcoming generations.
Gordon
Taylor discusses several of these changes. As an evolutionist, he is
hoping that they may point the way toward means by which evolution could
occur. But you will notice that, in each instance, only sub‑species
changes occurred.
'Taylor
himself admits that, in spite of many unusual sub‑species
modifications, there is no evidence that one species has ever changed
into another.
"In
the seventeenth century the British naturalist
John Ray said that no species ever gave birth to another spaces, meaning
that rabbits do not give birth to hares, nor owls to pigeons. That
observation remains true. "‑'G. R. Taylor, Great Evolution
Mystery (1983). p. 79.
"In
all the thousands of fly-breading experiments
carried out all over the world for more than
fifty
years a distinct new species has never been
seen
to emerge."-'Op
cit.,
p 34.
But
he notes that some very unusual in-species changes have also
occurred: By switching altitudes, salamanders change the number of
offspring and where they are produced.
"In
the early part of this century a young Viennese investigator, Paul
Kammerer, was conducting painstaking experiments with salamanders which
seemed to some to show conclusively the existence of Lamardcian
inheritance [environment controls inheritance]. This was ironical, since
Kammerer was a Mendelian [genetics controls inheritance]. Kammerer used
two contrasting animals in his first series of
experiments: a black Alpine
salamander which bears two offspring at a time and does so on land,
and a spotted salamander which
produces from ten to fifty larval
offspring at a time and these in water. Kammerer brought up spotted
salamanders in an Alpine environment and black ones in a lowland
situation. They switched roles, the Alpine one producing numerous larvae
and the spotted one
two
live offspring. What was more astonishing, this pattern persisted in
subsequent generations."‑'Op. cit., pp. 42‑43.
Then *Kammerer used type of soil as the environmental factor:
"For
the next eleven years Kammerer continued his experiments, bringing up
black and yellow salamanders on yellow and black soil. You can guess
what happened: the black ones became yellow, when on yellow soil; the
yellow ones black. And this too persisted. His findings having been
confirmed by another worker, Kammerer received the prestigious Summering
prize."‑'Op. cit., p. 43.
But
then ' Kammerer began working with Proteus, and discovered that in some
environments it developed eyes, while in others it did null Environment
can produce eyes!
"These
were not the only startling observations bearing on inheritance made by
Kammerer. He turned to the blind newt, Proteus. If Proteus is brought up
in the light, it remains blind. But Kammerer tried raising them in red
light, whereupon they developed eyes, showing shat the hereditary
infatuation for creating eyes had not been lost, only
suppressed."‑ 'tap. cit., p. 43.
That
small newt probably had eyes at any earlier time, but then, under the
environmental stress of continual darkness, the eyes disappeared. Yet they
were still in the DNA code. When the environment changed back‑the
eyes reappeared..
*Schroeder
partially changed the setting in which willow moth caterpillars prepared
for pupation. The caterpillars adapted to this environmental
change‑and some immediately passed the new trait on to the very next
generations
"Filly
years ago, for instance, one Harry Schroeder conducted an intriguing
experiment with the wilfovwrnorth caterpillar. This caterpillar places
itself on a leaf and rolls the leaf round itself before pupating,
fastening it down with a web. Normally, it starts by drawing the tip of
the leaf over itself, but Schroeder, with fiendish cunning,
systematically cut off the tips of all the leaves on which caterpillars
had taken up position. Sensibly enough, they responded by drawing the
side of the WO over instead. When these caterpillars had produced another
generation, Schroeder found that, of nineteen offspring. four drew the
side of the leaf over, not the tip, when their time to pupate came around.
It may be said that this was inheritance of an acquired behaviour, not a
structure."‑'Op. cit., p. 48‑49.
'Taylor
also wonders why creatures are born with what they will not need until
later in life.
..Very
conveniently the ostrich is born with calluses on its rump, breast and
pubis, just where it will later press upon the ground where it sits. These
callosities are well defined in the unhatched Chick."‑'Op,
cit., p. 3T.
The
environmentally‑caused factor of calluses passed on to future
generations through the DNA code. It is likely that provision for the
calluses were keyed into the code from the beginning. It is also possible
that the calluses were actively present at birth in the very first
generation when ostriches were first created.
*Taylor
was searching for answers. According to ' Darwin's theory, a creature
developed features it needed for survival, yet Taylor expresses his
dissatisfaction. He questions how that could be true since species can
have so many varied features and yet all survive very nicely. For example,
some sheep have home, some do not, yet all do equally well; some grazers
are short‑necked and others are long‑necked; yet all obtain
enough food.
In
addition, Taylor asks why should characteristics continue in creatures
which are not seemingly needed?
"Again,
within one square metre of ground a score of species of snail may be
found. What advantage can any one of them have? Persistence of unneeded
characters is hard b explain.
Op.
cit., p. 181.
Why
do some armadillos have a fur coat while others do not? How can this be
explained by evolutionary theory?
"Another
puzzling aspect of the question is why some creatures make an adaptation
which seams, on the face d it, helpful, while other mernbers of the
genus nwnape perfectly well without it. For instance. one spades of
Peruvian wma diuo, which lives high up, has evolved a fur coat, but other
species living equally high have not. So where was the
advantage?"‑ 'Qp. cit., p. 180.
Evolutionists
declare that jawless fishes were not very capable, so they changed into
jawed fishes. But *Taylor wonders how that idea can be true since the
jawless fishes have a survival rate equal to that of the jawed fishes:
"Why,
then, do we still find lampreys, which are jawless fishes, doing very well
today? If possessing jaws was such a wonderful advantage, why did not
the jawless fishes realise how backward they were and succumb?
"These
primitive vertebrates take us back to 500 million years ago; but a still
more extraordinary example of failure to evolve is found in the
bacteria. Since they reproduce themselves, in favourable conditions,
every twenty minutes, they might be expected b evolve faster than other
organisrns‑but fossil bacteria going back three and a half billion
years, to the threshhold of life itself, have been recovered and are
virtually identical with modern forms.
"There
are really two problems here. First, why did some species fail to give
rise to superior forms? Second, why, when they did give rise to superior
forms, did not the inferior fame die out, worsted in the evolutionary
straggle?"‑'Op. at, pp. 227.
But,
back again to our main point, 'Taylor notes another acquired
characteristic that was passed on to descendants, although, again, the
species itself did not change.
"Frederick
Griffiths placed rats on slowly revolving turn tables for periods of up
to one and a half years. When the wretched animals were freed their heads
constantly flicked in the direction in which they had been rotated, and
their eyes flicked also. This flicking automatism reappeared in their
progeny."‑'Op. cit., p. 49.
Flagellella
are long, whiplike projections that help small creatures push themselves
through the fluid surrounding them. But there is a microscopic worm which
may or may not have a flagella, according to the environment it is in:
"If
the little worm Naeqleria is placed in a strong salt solution it develops
flagella; in a weak one it does not. So form is certainly dependent on
external factors, at least in some cases."'Op. cit., p. 243.
Modifications
were made in plants by changing the soil they were in. But these changes
were then passed on to their descendants. As usual, no cross‑species
changes had occurred.
"Some
of the most convincing experiments have been done with plants. For
instance in 1962 Alan Durrant at the University College of Wales,
Aberystwyth, induced changes in the flax plant by cultivating it with
different types of fertiliser. Same plants became heavier and larger,
others lighter and smaller. Astonishingly, these trends persisted for
several generations. A few years later, J. Hill, at the Welsh Plant
Breeding station, got rather similar results with tobacco plants, the
flowering time also being affected. Durrant's work was carried forward by
Chris Cullis and these lines of plants are still being propagated as I
write, almost twenty years later."‑'Op. cit., p. 49.
The
plants were probably pre‑coded for different reactions to
different environmental conditions. When placed in the different
environment, a message was sent to the cell which was read into the DNA,
and the offspring expressed the same modifications.
*Waddington
used an environmental factor to produce an effect which was inherited by
later generations. Once again, no traps‑species change occurred.
"Perhaps
the most convincing, or anyway puzzling, expedrrentii; were carried out by
Con• rod Waddington, of Edinburgh University, about 1940. He exposed
fruit‑flies b heat‑shock and produced some mutant flies which
lacked the usual cross‑veins in their wings. When he heatshocked
the next generation this mutation appeared more frequently, and as he
continued with subsequent generations finally aces‑veinless flies
were appearing even when no heat‑shock was administered. This looked
so uncommonly like i‑amarckian inheritance that Waddington, as a
highly orthodox biologist, was disturbed."'Op. cit., pp.
49‑50.
*Waddington
did not use mutation‑producing radiation or chemicals. He only used
heat. Yet traps‑generation changes were produced. The more typical
breeding experiment is keyed
to
breeding for genetic variations, apart from environmental factors:
"An
experiment with plants that is often held
up
as being particularly convincing was launched
in
1903 at the Illinois Agricultural Experiment Station
and continued until 1927. A population of
corn
was grown, the parent for the next generation
always being the plants with ears closest: to
the
ground. At the start, the average height of
ears
above the ground ranged from 43 to 56
inches.
At the end of twenty‑four years, the average
had become a mere eight inches, and this
trait
bred true. As a check, plants with the highest
ears were also selected and bred; in this case
the
average height rose to 120 inches‑10 feet
by
the end of the experiment."‑'Op. cit., p. 34.
The
corn experiment is more like what we are used to hearing about. This could
be a simple selecting out from among a variety of genetic factors,
rather than the shock of a sudden new environment which affects later
descendants, as we find in the newt, willow‑moth caterpillar, and
turn‑table rats.
How
should we relate all this what we already know about genetics and the DNA
code?
First,
can a new species originate, or can one species change into different
species? No, it can never be done. The DNA code must be there in place to
begin with, and only a super‑intelligent Person could have placed
that code there to begin with. The limitations of the code forbid any
cross‑species changes.
Second,
can any species change its DNA? No, it cannot. Every last zillionth of a
characteristic change possible to a given species had to be in the DNA
code BEFORE the change could be made. The possibility of every possible
change had to already be in the DNA. Whatever the possible change may
have been, the possibility of it had to be pre‑coded into the DNA
before it was expressed.
Third,
can a given species change its features and habits? Yes, it can. We have
already considered examples of that.
Fourth,
could some of those changes be environmentally‑caused? (That is,
during the lifetime of the creature, something happened which caused a
change which it then passed on to its descendants.) Yes, earlier in this
chapter we have already viewed some instances. More will be cited below.
An example would be one of the descendants of the first finches to the
Galapagos Islands which began biting off a cactus spine, and then using it
as a needle to poke into holes and pull out grubs which it then swallowed.
That environmentally‑caused tool‑using trait was passed on to
its descendants.
How
can ve combine together those four points into a sensible, coherent,
workable pattern? Basically, how could all the changes be potentially in
the DNA to begin with, and yet some of them be environmentally produced?
The
answer is just that. All of the possible variations within a species were
beforehand accounted for within the limitations of the DNA coding. The
changes were all potententially in the DNA code to begin with. But the
code provided for some of the changes to be influenced by environmental
factors! That sentence is the single addition to the standard concepts
we have reviewed
throughout these three books, in regard to DNA, its coding, and
sub‑species changes.
On
an adjacent page is an outstanding example of this principle in action:
The Hawaiian sicklebill is a small bird which is only found on the
Hawaiian Islands. At some earlier time those Islands were colonized by
birds, probably, finches from
America. Because there were so many unfilled feeding niches available on
the islands, these birds adapted over a period of time to a variety of
foraging habits. Ultimately 22 sub‑species (8 of which are now
extinct) developed. The surviving 14 are shown in the accompanying
illustration.
HAWAIIAN
HONEYCREEPER
At
some earlier time, American finches migrated to the Hawaiian Islands..
Gradually, in accordance with variation ranges already in its DNA, this
species of bird produced a variety of sub‑species to fill various
empty ecological niches. Eventually 22 sub‑species were formed, of
which 8 are now extinct. Illustrated below are the surviving 14. The bills
are adapted to everything from nectar‑sipping and nutcracking to
grubbing beetles from trees.
These
birds are essentially identical in feet, legs, wings, body shape, and
eyes. Their heads show slight variations, and their bodies vary slightly
in size,‑but it is in their bills that the most striking differences
are to be found.
These
bills have adapted for everything from long, narrow bills for
nectar‑sipping, heavy beaks for nut‑cracking, to bills adapted
to grubbing beetles from trees. Different feeding habits led to changes
in bill shapes.
Applying
the new principle, we can more easily understand what happened here. The
DNA of these birds was coded, not only for random variational
changes,‑but also for environmental input data which triggered the
DNA to make other variational changes.
In
other words, if this new view be correct, the DNA is coded not only to
send data out into the cell‑but also to receive information from the
cell. But inherent within the code of each species, only certain
environmental factors can trigger DNA variations that will cant' through
to posterity. _
This
is vividly shown in the Hawaiian sicklebill illustration. Look at it
again. The DNA was primarily coded to accept environmental change data
in regard to the bill, and not the rest of the bird. Some of those birds
could surely have used different shaped bodies, wings, legs, or feet. But
no changes occurred there; only bill changes were possible.
In
this way, changes in the environment could affect the DNA‑and thus
be passed on to the next generation‑only to the extent that the DNA
had earlier been coded to accept such changemaking input data. All those
Hawaiian sicklebill patterns were already in the DNA gene‑pool
before the parent birds ever flew to the Hawaiian Islands. The genetic
pool of those finch bills was much larger than, for example, the genetic
pool for their legs and feet. Yet the changed feeding habits could well
use different legs and feet, as DNA in the nucleus are sent out to other
cell particles so that various things can be done. It is also known that
messages are sent to the DNA to issue orders (information packets) that
will enable more raw materials to be manufactured, assembled, or made
into additional structures. So, although relatively little is known
about how it is done, yet it is known that information is both sent to the
DNA and from the DNA.
Because
of this, not only can a given species be coded for summer and winter
(brown coat in summer and white in winter), but also for various
altitudes, light and darkness, and a variety of other changed
environmental conditions.
Such
a concept is a far cry from Lamarkism, which teaches that any kind of
in‑species hereditary change can be made by any kind of environmental
activity or effect, and that those environmental changes eventually result
in new species.
The
new view suggested here Is that environment
can only affect heredity to the extent that precoded DNA permits it to happen. In
addition, all the alternate possibilities were already pre‑coded Into the DNA helix
This
revised definition‑which offers a wider range of DNA
functions‑appears able to solve a variety of otherwise puzzling
facts, while agreeing with genetic knowledge.
Scientists
generally accept the assumption that hereditary changes based on
environmental factors are theoretically impossible. Yet they occur
anyway.
As
mentioned earlier, when people move loser to the poles, their skin becomes
lighter. They need less sun‑shade. When people move closer to the
hot, bright areas near the equator, their skin gradually becomes darker.
Those who have lived in such areas the longest have become almost black.
The same with the eyes; northern Europeans have tinted irises, and those
in Africa have nearly black irises, for their environment requires more
shading of the retina. They have built‑in surr glasses! Hair also
becomes darker near the brightest areas of the globe. The top of the head
thus is given better protection from sun‑stroke. What about the
Eskimos, and other peoples living in Arctic areas, who have dark hair
and eyes? Anthropologists recognize that they have moved there more
recently. Eskimos have the appearance of Mongolians and migrated
northward in more recent times, and from there went south and populated
North, Central, and South America.
There
is a far greater range of possibilities within the DNA than we had before
imagined. Recall to mind Kammerer's salamanders which changed their
hereditary manner of bearing young, because of environmental changes; and
the willow‑moth caterpillar, which so fully adapts to a new
environmental pattern‑forced on it by experimenters‑that it
bequeaths the new pattern to its offspring!
(1)
In each of these instances, the gene pool within the DNA could permit
these traits to be passed on to progeny. But the changes never involve
more than slight modifications, which is far from a trans‑species
change.
Likewise
with the turn‑table rats and the blind newts which developed eyes;
in each instance, it could be done because the DNA coding permitted it
to be done.
Dogs
trained as sheep dogs for generations will show a herding instinct which
other canines do not have.
There
are not only limits to the code of each species, there is also a range to
that code. The
first
is breadth and the second depth. The limits to the side keep new species
from being formed. But the rich quantities of potential code combinations
within those limits provide for large numbers of sub‑species
changes. Exploring the full range of the code produces mathematical geniuses
in people and nectar‑sipping bills in finches.
Over
the years, Persian cats have been bred with shorter and shorter noses
until many have noses so short the end is right between the eyes. But it
would be useless to try to breed Persians with wings or three eyes. (1) If
it is not in the DNA, it cannot be produced. (2) Only that amount of
change for a given trait which is in the DNA for that species can be
produced.
This
range of code possibilities can make two types of variations: (1) the kind
of usual geneshuffling changes which make you a little different than
your parents and your children, and (2) codes already in place which await
triggering by environmental factors to_ be set in place.
The
most remarkable example cited by 'Taylor was the blind newt, Proteus,
which developed eyes when brought up in red light. Within the DNA of the
Proteus were the trait factors for perfectly functioning eyed Normally,
that newt never had eyes, but the coding for eyes were there anyway.
Please do not imagine that the codes for complete, functioning eyes is
any small thingl Those eyes were not MADE by the environment; they were
already there in the DNA, even though not expressed in the head until
needed.
The
coding dictated that, when red a infrared light was present, the newt
would develop seeing eyes. Thousands of generations of blind, noeyed
newts might live and die, but the coding was there waiting for certain
environmental condttions‑and then the eyes appeared!
But
M all the observations and experiments,there is always, always, no hint
of a changeover from one species to another. Evolution never occurs. The
DNA prohibits it. Evolution is something which has no real existence
outside the imagination of certain men.
What
we have here is not "inheritance of acquired characteristics,"
but Inheritance of expressed
characterlstksl The characteristics were already in the DNA, and when a
need arose for them to be expressed, then they could gradually enter the
active inheritance factors. But they do not enter immediately.
Such
an occurrence would take place if a Scandinavian moved to central Africa
and he and his descendants remained there permanently. If, the same time,
an African moved to Scandinavia and remained there permanently,‑two
or three thousand years later, the skin color would be totally
switchedl
In
his book, 'Taylor also mentioned plants and animals that changed feather
and leaf cokx, as well as other features, when moved from one climate to
another. This could help explain why species
in one locality appear somewhat different than related species elsewhere
in the works. No cross‑species change occurred; it was only a plant
or animal expressing enough other facets within its DNA that it appeared
to be a different sub‑species.
'Taylor
mentions a bird which, when moved from one South Pacific island to
another, changed colors. But then we know that when canaries are fed
special diets, they change from yellow to orange, and when hydrangias are
placed in acid soil they have blue flowers, while in alkaline soil pink
flowers. Environmental factors, yes, but species change, no.
This
concept would permit sub‑species environmental changes, if the
traits for those changes have always been in the gene pool range of the
DNA of that particular species.
There
are several hundred sub‑species of cichlids inhabiting several
African lakes. Each subspecies has different feeding and nesting habits.
Some are remarkably different in those habitsl Yet all are clearly
cichlids, with only slight differences in size, color, teeth, etc. The
DNA permitted certain sub‑species changes so they could adapt to the
various feeding and nesting niches in those lakes, but not many other
changes.
A
single species was brought into an isolated area, where there were many
unfilled life niches. Sub‑species proliferated, and eventually there
were many sub‑species, each living and doing things a little
differently than the others. In the procase, some actual alterations in
size, body structure, and function occurred. Inherited differences in
memory patterns even took place.
More
examples of species change will be found in chapter 15.
(You
have probably read about the remarkable experiment involving hydra. Under
a microscope this microscopic worm‑like creature looks like a black
arrow. It inhabits fresh‑water ponds. These small creatures were
taught certain information, and then chopped up and fed to other hydras.
By so doing, information in the brains of the choppedup hydras was
transferred to the other hydra which ate theml)
Factual,
habitual patterns were actually transferred by eating!
As
a result of special breeding, dogs, pigeons, cats, and chrysanthemums come
in a wide variety of sub‑species. Plant breeders have tried to
produce a wide variety of every flower, but the mum was found to have a
larger gene pool than most flowers, and so it has been transformed into a
startling number of varieties.
Another
example of changes in structure as a result of environmental demands would
be the unusually large chests and lungs of the inhabitants of Nepal. The
Nepalese live on the roof of the world, thousands of feet above the rest
of us. Mount Everest is in Nepal. A lack
of oxygen at that high elevation causes them to spend their lives
breathing
deeply.
(In
contrast, there are examples of changed patterns through instruction
rather than heredity: Japanese scientists spent years studying a certain
ape native to a northern island in the Japanese island chain. The
scientists threw rice on the sand. Most of the apes spent hours carefully
picking rice out of the sand, but one adult female scooped it up and
tossed it into the ocean. The sand quickly dropped to the bottom and the
rice floated at the top. She then scooped it back up and swallowed it.
(Trying
to teach the other apes, she was successful with the young ones. Soon
the other adult females adopted the new feeding pattern also. But the old
males refused to be taught by women and children. They kept laboriously
picking rice grains out of the sand.)
This
concept of environmental adaptation of species in accordance with gene
pool limitations, may also help in explaining changes in species after the
Fall (Genesis 3). Most American bears eat bees, honey, fish, animals, and
whatever else they might find. Yet the ancestral bear would have been a
vegetarian, with capacity in its gene pool for a carnivorous diet. The
panda bear in China has continued down to the present time as a total
vegetarian. Yet in every other way, ft
is bearlike.
In
anticipation of the Fall, the Creator could have placed within the various
creatures DNA coding factors needed to later survive under the radically
changed environment they wouki encounter after sin entered. That later
changed environment could then have brought forth the changes in the
creatures.
An
example of this would be the shark which can smell even the minutest
quantity of blood in the water, the dolphin which can echo-locate, using
underwater radar (sonar) to locate fish to eat, and the many fish which,
sensing sideways water pressure, are alerted to instantly flee the
approach of dangerous creatures coming toward them.
Why
does the tiger have those large fleshripping teeth, when he was
originally a vegetarian? In an earlier chapter, we mentioned a mammal
which had a tooth which in earlier times disappeared,—and later
reappeared! In foreknowledge of the Fall, the tiger could have had its
DNA pre-coded so it could later adapt to larger teeth, a shorter gut, needed for a carnivorous
diet.
Knowing
ahead of time that man would fall into sin, and the terrible consequences
that would ensue, the DNA of the tiger could have been pre-coded for
such an eventuality when it was first made. (It is also possible that
later modifications in its DNA could have been made afterward by the
Master Codemaker.) Either possibility would explain many things we see
about us.
Fortunately,
life as we now know ft will not continue on much longer. Satan claimed
that God's laws could not be obeyed, but Christ died to forgive and enable
men to do so. Erelong, the violence will be no longer exist. All of God's
children throughout the universe will then be a peaceful, happy family.
The lion will dwell with the lamb and misery and suffering will forever be
ended.
We
might here mention that there is only one creature mentioned in the Bible
which apparently had its DNA changed after the fall: the serpent. A major
physical change occurred, for prior to the fall it would have had another
means of locomotion: legs, or legs and wings; but afterward it could
only crawl. At the Scopes Trial in 1925, Clarence Darrow asked William
Jennings Bryan in ridicule, "How did the snake walk; on its
tail?"
But
the Bible clearly states that a genetic change was made in the serpent.
Before then, it must have had wings and legs, or legs alone. It is of
interest that ancient legends from around the world speak, not only of a
worldwide Flood, an Ark with eight people, and the Fall beforehand, but
also of a tree of life and a flying serpent.
There
is yet another intriguing aspect to this: A divine hand not only provided
the gene pool for each species, but, in foreknowledge of what postFall
conditions would bring, also provided that that gene pool be wide enough
to provide adaptive ability for each species under the dramatically
changed conditions that would later bring oceans, deserts, tundra, swamps,
etc.
Marine
fish were given cleaner fish to protect them from parasites. The late '
Conrad Limbaugh of the Scripps Institute of Oceanography was the first to
study them. A cleaner fish selects a place in the ocean to carry on its
work, and then waits. Soon it watches as large, dangerous fish swim up and
patiently wait in line for it to clean their sides, faces, and even inside
their mouthsl
There
are multiplied thousands of instances in which living creatures do wiser
things than they could possibly have the native sense to do.
Why
do the various cleaner fish, Pedersen's shrimp, and the La Senorita wrasse clean parasites from immense fish able to swallow
them in one gulp? Why do the big fish not hurt them? Why do they know
these little creatures will help them?
In
the design chapters of this book (chapters 8, 12, 16, 20, 24, 28, 32, 36
and 40), you have found hundreds of astounding facts about the earth,
plants, animals, and man which defy any explanation other than divine
wisdom at work. There simply is no other answer.
What
about the little frog, mentioned in chapter 20, which has the markings of
a dangerous rat on its back? That frog never, ever sees its backs How does
ft know to instantly turn its back on its predator‑and position
itself in such as way as to frighten him off? There can only be one answer:
God did it.
We
have here no "watchmaker god," who created and then departed. We
see here the hand of the Creator, who made His creatures and then Is
continually guiding His vast creation. "For in Him we live, and move,
and have our being." Acts 17:28.
There
is the crab which keeps a small stone resting on sensitive hairs, enabling
it to balance. If it loses that stone, it quickly picks up another, or, in
some cases, secretes stony material to replace it. How does the crab
know to do that? How did it know to do it to begin with?
There
is the bola spider which, instead of weaving a web, swings a tiny rope
of spider thread around its head‑and then hurls it after its prey.
How does it know to do that? Why does it keep doing it, over and over,
even when it may not succeed in accomplishing anything by doing so?
'De
Witt discovered that orb‑weaving spiders never run out of raw
material, nor end up with a surplus. They first figure out how much they
will need for the circular web‑and then manufacture that amount of
fluid. Then they begin work on the web.
Why
does the Birgus latro crab climb out of the ocean, crawl over to a coconut
tree, laborously climb it-saw through a hard coconut stem, drop the nut to
the ground,-then climb back down, retrieve and enjoy it for lunch? How can
it have the brains to carry out such a complicated operation?
Why
does the larva of the caddis fly build a case for itself? If destroyed, it
replaces it; if given too large a case by the experimenter, it adjusts it
to the right size. It inherently knows just what to do.
Where
did that wisdom come from? It did not come from the caddis fly.
Why
do baby bees, as soon as they emerge from the egg, know exactly what to do
in the hive? At several different stages of their lives, they will have to
perform different functions, yet they always know what to do at the
right time. Where did they obtain this wisdom, since none of the other
bees spent a moment of time instructing the newborn?
Why
can so many creatures know they must molt or die? How do they do it? Why
is there such remarkable examples of protective coloration and
"mimicry"? How can the birds know to track their flight over
vast oceans, guided only by the stars and earth's electromagnetic field?
It
was Infinite Wisdom --the hand of God which placed the knowledge
needed by those birds within their DNA. There can be no other answer.
On
and on it goes, lessons calling us to acknowledge our Creator,
convictions pleading with us to worship and serve Him.
In
conclusion, what name shall we give to this new concept introduced here?
We could call it Pre‑coded
adaptations, or the Inheritance
of expressed characteristics. Perhaps
this view will be thought to be incorrect and discarded. If so, the
puzzles remain and a theory agreeing with scientific facts is needed to
explain them.
