How Did We All Come From Adam and Eve?
By Babu G. Ranganathan
Young people, and even adults, often wonder how all the varieties or
"races" of people could come from the same original human ancestors. Well, in
principle, that's no different than asking how children with different color
hair (i.e., blond, brunette, brown, red ) can come from the same parents who
both have black hair.
Just as some individuals today carry genes to produce descendants with
different color hair and eyes, humanity's first parents, Adam and Eve,
possessed genes to produce all the variety and races of men. You and I today
may not carry the genes to produce every variety or race of humans, but
humanity's first parents did possess such genes.
All varieties of humans carry genes for the same basic traits, but not
all humans carry every possible variation of those genes. For example, one
person may be carrying several variations of the gene for eye color ( i.e.,
brown, green, blue ) , but someone else may be carrying only one variation of
the gene for eye color ( i.e., brown ). Thus, both will have different
abilities to affect the eye color of their offspring.
Some parents with black hair, for example, are capable of producing
children with blond hair, but their blond children (because they inherit only
recessive genes) will not have the ability to produce children with black hair
unless they mate with someone else who has black hair. If the blond descendants
only mate with other blondes then the entire line and population will only be
blond even though the original ancestor was black-haired.
In reality there is only one race - the human race - within which exists
myriad variations and permutations.
The evidence from science shows that only microevolution (variations
within a biological "kind" such as the varieties of dogs, cats, horses, cows,
etc.) is possible but not macroevolution (variations across biological "kinds",
especially from simpler kinds to more complex ones). The only evolution that
occurs in Nature is microevolution (or horizontal evolution) but not
macroevolution (vertical evolution).
The genetic ability for microevolution exists in Nature but not the
genetic ability for macroevolution. The genes (chemical and genetic
instructions or programs) for microevolution exist in every species but not the
genes for macroevolution. Unless Nature has the intelligence and ability to
perform genetic engineering (to construct entirely new genes and not just to
produce variations and new combinations of already existing genes) then
macroevolution will never be possible in Nature.
We have varieties of dogs today that we didn't have a couple of hundred
years ago. All of this is just another example of microevolution (horizontal
evolution) in Nature. No matter how many varieties of dogs come into being they
will always remain dogs and not change or evolve into some other kind of
animal. Even the formation of an entirely new species of plant or animal from
hybridization will not support Darwinian evolution since such hybridization
does not involve any production of new genetic information but merely the
recombination of already existing genes.
Modifications and new combinations of already existing genes for already
existing traits have been shown to occur in nature but never the production of
entirely new genes or new traits. This is true even with genetic mutations. For
example, mutations in the genes for human hair may change the genes so that
another type of human hair develops, but the mutations won't change the genes
for human hair so that feathers, wings, or entirely new traits develop.
Mutations may even cause duplication of already existing traits (i.e. an extra
finger, toe, etc. even in another part of the body!), but none of these things
qualify as new traits.
Evolutionists believe that, if given enough time, random or chance
mutations in the genetic code caused by random environmental forces such as
radiation will produce entirely new genes for entirely new traits which natural
selection can act upon or preserve.
However, there is no scientific evidence whatsoever that random mutations
have the ability to generate entirely new genes which would program for the
development of entirely new traits in species. It would require genetic
engineering to accomplish such a feat. Random genetic mutations caused by the
environment will never qualify as genetic engineering!
Mutations are accidents in the sequential molecular structure of the
genetic code and they are almost always harmful, as would be expected from
accidents. Of course, just like some earthquakes that don't do any damage to
buildings, there are also mutations that don't do any biological harm. But,
even if a good mutation does occur for every good mutation there will be
hundreds of harmful ones with the net result over time being disastrous for the
species.
Furthermore, only those mutations produced in the genes of reproductive
cells, such as sperm in the male and ovum (or egg cell) in the female, are
passed on to offspring. Mutations and any changes produced in other body cells
are not transmitted. For example, if a woman were to lose a finger it would not
result in her baby being born with a missing finger. Similarly, even if an ape
ever learned to walk upright, it could not pass this characteristic on to its
descendants. Thus, modern biology has disproved the once-held theory that
acquired characteristics from the environment can be transmitted into the
genetic code of offspring.
Most biological variations within a biological kind (i.e. varieties of
humans, dogs, cats, horses, mice, etc.) are the result of new combinations of
already existing genes and not because of mutations.
For those who are not read-up on their biology, a little information on
genes would be helpful here. What we call "genes" are actually segments of the
DNA molecule. DNA, or the genetic code, is composed of a molecular string of
various nucleic acids (chemical letters) which are arranged in a sequence just
like the letters found in the words and sentences of a book. It is this
sequence of nucleic acids in DNA that tells the cells of our body how to
construct (or build) various proteins, tissues, and organs such as nose, eyes,
brain, etc. If the nucleic acids in the genetic code are not in the correct
sequence then malfunctioning, or even worse, harmful proteins may form causing
serious health problems and even death.
There is no law in science that nucleic acids have to come together in a
particular sequence. Any nucleic acid can just as easily bond with any other.
The only reason for why nucleic acids are found in a particular sequence in the
DNA of the cells of our bodies is because they are directed to do so by
previously existing DNA. When new cells form in our bodies the DNA of the old
cells direct the formation of the DNA in the new cells.
The common belief among evolutionists is that, if given millions of
years, radiation and other environmental forces will cause enough random
changes (mutations) to occur in the sequential structure of the genetic code of
a species so that entirely new sequences for entirely new genes will develop
which in turn will program for the formation of entirely new biological traits,
organs, and structures that natural selection can then act upon.
Would it be rational to believe that by randomly changing the sequence of
letters in a cookbook that you will eventually get a book on astronomy? Of
course not! And if the book were a living being it would have died in the
process of such random changes.
Such changes, as transforming one book into another or the DNA of one
species into the DNA of another, especially one more complex, simply cannot
occur by random or chance alterations. It would require intelligent planning
and design to change one book into another or to change the DNA of a simpler
species into the DNA of a more complex one.
Yes, it is true that the raw biological materials and chemicals to make
entirely new genes exist in every species, but the problem is that the random
forces of nature (i.e. radiation, etc.) simply have no ability to rearrange
those chemicals and biological materials into entirely new genes programming
for entirely new traits. Again, mutations only have the ability to produce
variations of already existing traits. It would require intelligent
manipulation of genetic material (genetic engineering) to turn a fish into a
human being. The random forces of the environment cannot perform such genetic
engineering!
If the environment doesn't possess the ability to perform genetic
engineering and if macro-evolution really did not occur then how else can one
explain the genetic and biological similarities which exist between various
species and, indeed, all of life. Although it cannot be scientifically proven,
creationists believe that the only rational explanation for the genetic and
biological similarities between all forms of life is due to a common Designer
who designed and created similar functions for similar purposes and different
functions for different purposes in all of the various forms of life from the
simplest to the most complex. Even humans employ this principle of common
design in planning the varied architecture of buildings!
If humans must use intelligence to perform genetic engineering, to
meaningfully manipulate the genetic code, then what does that say about the
origin of the genetic code itself!
Many have confused natural selection with evolution itself. Yes, Charles
Darwin did show that natural selection occurs in nature, but what many don't
understand is that natural selection itself does not produce biological traits
or variations.
Natural selection can only "select" from biological variations that are
produced and which have survival value. The real issue is what biological
variations can be naturally produced. What biological variations are naturally
possible? When a biological change or variation occurs within a species and
this new variation (such as a change in skin color, etc.) helps that species to
survive in its environment then that variation will be preserved ("selected")
and be passed on to offspring. That is called "natural selection" or "survival
of the fittest". But, neither "natural selection" nor "survival of the fittest"
has anything to do with producing biological traits and variations.
The term "natural selection" is simply a figure of speech. Nature, of
course, does not do any active or conscious selecting. It is an entirely
passive process. Darwin did not realize what produced biological variations.
Darwin simply assumed that any kind of biological change or variation was
possible in life. However, we now know that biological traits and variations
are determined by the genetic code.
Natural selection works with evolution but it is not evolution itself.
Again, since natural selection can only "select" from biological variations
that are possible, the real question to be asking is what kind of biological
variations are naturally possible. How much biological variation (or how much
evolution) is naturally possible in Nature? As we have seen all biological
variation or evolution is limited to within plant and animal kinds.
Another reason for why macroevolution is not possible in Nature is
because a half-evolved and useless organ waiting millions of years to be
completed by random mutations would be a liability and hindrance to a species -
not exactly a prime candidate for natural selection. In fact, how could species
have survived over, supposedly, millions of years while their vital (or
necessary) organs were still in the process of evolving!
How, for example, were animals breathing, eating, and reproducing if
their respiratory, digestive, and reproductive organs were still incomplete and
evolving? How were species fighting off possibly life-threatening germs if
their immune system hadn't fully evolved yet?
Scientist and creationist Dr. Walt Brown, in his fantastic book "In The
Beginning", makes this point by saying, "All species appear fully developed,
not partially developed. They show design. There are no examples of
half-developed feathers, eyes, skin, tubes (arteries, veins, intestines, etc.),
or any of thousands of other vital organs. Tubes that are not 100% complete are
a liability; so are partially developed organs and some body parts. For
example, if a leg of a reptile were to evolve into a wing of a bird, it would
become a bad leg long before it became a good wing."
Usually what is meant by the term "biological kind" is a natural species
but this may not always be the case. The key to keep in mind here is that in
order for evolution in nature to occur from one biological "kind" to another
biological "kind" entirely new genes would have to be generated and not just
merely modifications and/or recombination of already existing genes. If, for
example, offspring are produced which cannot be crossed back with the original
stock then there is, indeed, a new species but if no new genes or traits
developed then there is no macro-evolution (variation across biological kinds)
and the two distinct species would continue to belong to the same "kind".
Science cannot prove we're here by creation, but neither can science
prove we're here by chance or macro-evolution. No one has observed either. They
are both accepted on faith. The issue is which faith, Darwinian
macro-evolutionary theory or creation, has better scientific support.
If some astronauts from Earth discovered figures of persons similar to
Mt. Rushmore on an uninhabited planet there would be no way to scientifically
prove the carved figures originated by design or by chance processes of
erosion. Neither position is science, but scientific arguments may be made to
support one or the other.
What we believe about life's origins does influence our philosophy and
value of life as well as our view of ourselves and others. This is no small
issue!
Just because the laws of science can explain how life and the universe
operate and work doesn't mean there is no Maker. Would it be rational to
believe that there's no designer behind airplanes because the laws of science
can explain how airplanes operate and work?
Natural laws are adequate to explain how the order in life, the universe,
and even a microwave oven operates, but mere undirected natural laws can never
fully explain the origin of such order.
Of course, once there is a complete and living cell then the genetic
program and biological mechanisms exist to direct and organize molecules to
form into more cells. The question is how did life come into being when there
was no directing mechanism in Nature. An excellent article to read by scientist
and biochemist Dr. Duane T. Gish is "A Few Reasons An Evolutionary Origin of
Life Is Impossible" .
There is, of course, much more to be said on this subject. Scientist,
creationist, debater, writer, and lecturer, Dr. Walt Brown covers various
scientific issues ( i.e. fossils, so-called transitional links, biological
variation and diversity, the origin of life, comparative anatomy and
embryology, the issue of vestigial organs, the age of the Earth, etc. ) at
greater depth on his website at http://www.creationscience.com .
On his website, Dr. Brown even discusses the possibility of any remains
of life on Mars as having originated from the Earth due to great geological
disturbances in the Earth's past which easily could have spewed thousands of
tons of rock and dirt containing microbes into space. In fact, A Newsweek
article of September 21, 1998, p.12 mentions exactly this possibility.
An excellent source of information from highly qualified scientists who
are creationists is the Institute for Creation Research (http://www.icr.org) in
San Diego, California. Also, the reader may find answers to many difficult
questions concerning the Bible (including questions on creation and evolution,
Noah's Ark, how dinosaurs fit into the Bible, etc.)at
http://www.ChristianAnswers.net.
It is only fair that evidence supporting intelligent design or creation
be presented to students alongside of evolutionary theory, especially in public
schools which receive funding from taxpayers who are on both sides of the
issue. Also, no one is being forced to believe in God or adopt a particular
religion so there is no true violation of separation of church and state. As a
religion and science writer, I encourage all to read my Internet article "The
Natural Limits of Evolution" at my website http://www.religionscience.com for
more in-depth study of the issue.
