The comprehensive
analysis of the chimpanzee genome
reveals a greater genetic difference from humans
The chimpanzee joins the group of animals whose
genomes have been deciphered by scientists. The data from
the chimp genome was compared to its human counterpart by
an international research consortium, whose studies have
been published in Nature. (1) According
to the findings of the consortium, humans shared many genes
with chimpanzees, but there were very important differences
as well. In fact, this first comprehensive genetic comparison
triples the percentage of differences suggested by previous
studies that relied on partial genome analysis. The latest
percentage of genetic similarity is 96% in comparison to
previous ones reported about 98.5%.
Chimps have been the fourth
mammal to be genetically sequenced after human, mouse and
rat - enriching the genomic treasure of scientists. 67
scientists have contributed to the consortium from countries
such as United States, Germany, Israel, Italy and Spain. "As we build upon the foundation
laid by the Human Genome Project, it's become clear that
comparing the human genome with the genomes of other organisms
is an enormously powerful tool for understanding our own
biology" says National Human Genome Research Institute
Director Francis S. Collins. (2)
An important reason of the decrease in genetic
similarity figure is that scientists have taken into account
various types of genetic difference. In previous studies
scientists picked only single nucleotide polymorphisms (SNPs)
as variations which gave figures such as 1.2% difference.
An SNP represents a single base pair difference between two
matched DNA sequences. In this latest study scientists considered
also other genetic differentiation types, such as indels
(insertions and deletions) that represent gaps corresponding
to unmatched nucleotide sequences between the human and chimp
sequences, which may be one to thousands nucleotide long.
The one shown below is a 3-nucleotide indel.
The %4 difference amounts to difference in 40
million base pairs, and represents 35 million SNPs and 5
million indels.
Obligatory reduction in propaganda
figures
Inclusion of indels in analysis has revealed how simplistic
and misleading previous analysis were. This is admitted in
a report by Nature News Service with comments from
Evan Eichler of the University of Washington School of Medicine
in Seattle, a member of the consortium:
…humans and chimps are not
quite the close cousins we thought. Crude past comparisons of our DNA showed
that our sequences were between 98.5% and 99% identical.
That is indeed the case when considering single-letter
differences in the DNA code, of which there are 35 million,
adding up to about 1.2% of the total sequence. But there
are other differences, Eichler says. The two sequences
are littered with duplicated segments that are scattered
in different ways in the two species, he reports in a
separate analysis. These regions add another 2.7% of
difference to the tally. "So the 1.2% figure
is woefully inaccurate," says Eichler. (3)
This is a very striking admission because for decades evolutionists
have mislead the public with 99% figure in their human-chimp
genetic similarity propaganda. Now that turns out to be founded
on simplistic and inaccurate interpretation.
Genetic similarity is not a proof of
common ancestry
Actually, whatever the genetic similarity, it constitutes
absolutely no contribution to the claim that humans and chimps
evolved from a common ancestor. Clearly, similarity between
genetic sequences does not prove common ancestry. Since chimps
and humans breathe the same atmosphere, have similar organs
and diets, it is of course natural for them to have similar
genetic sequences - that, for example, provide them with
the similar biochemistry. The existence of similar instructions
in the manuals of two similar devices is no proof that these
devices came into existence as a result of coincidences,
neither do the genetic similarities between organisms provide
any evidence for the claim that they evolved from a common
ancestor by chance. Genetic information contained in the
DNAs of living beings is staggeringly complex. A mathematical
analysis of this complexity demolishes the materialist/evolutionist
claims. The existence of genetic information and its revealing
similarities between organisms constitutes a concrete evidence
for the fact that living beings are created by God.
Behind the statistics
When we read headlines such as "scientists find man
and chimp are genetically 99.44% similar" we are led
to believe that these are fully objective and precise estimates.
It is hard to think of something else, when the number even
includes four tenth and four hundredth digits and "scientists"
are doing the estimates! However, this impression is deceptive
and merely supports the evolutionist bias of evolutionist
scientists.
To uncover the bias, let us consider the two sequences comprising
20 DNA bases of below (bases, or nucleotides, are like the
steps of the DNA ladder). They are from the same region of
DNA, first being from the baboon and the second from orangutan. (4) If
they are aligned in parallel rows, they reveal obvious differences.
(Colored bases in italics indicate where sequences are different.
A, T, G, C represent bases Adenine, Thymine, Guanine and
Cytosine respectively.)
If you are biased to express similarities, on taking a closer
look, you can see that although the sequences are different,
they include identical pieces. To make them look more similar,
you may invoke a hypothetical gap and align them like this:
Now the sequences are almost identical. You have made them
look as though the second sequence has lost (or the first
one has gained) one nucleotide at the site where C and the
gap reside. And if you make a calculation, you will find
that percentage of similarity has significantly increased.
But there's a serious problem. You have added an element
of subjective interpretation to the data.
And that is only a small amount compared to what you can
do with larger sequences. Long sequences from two organisms
almost never can be perfectly aligned in parallel rows, without
any breaks in the continuity of nucleotides. This opens the
door to interpreter to selectively align nucleotides, as
he would like to see them.
To put this into perspective let us see how 40 nucleotides
of human DNA and 54 nucleotides of orangutan DNA can selectively
be aligned. In the two alignments below, the first row represents
the human sequence while the second one represents the orangutan
sequence (5):
Note that the order of nucleotides are exactly the same
in the two alignments. But the number of indels and SNPs
change significantly between the two interpretations. And
while this example compares 40 and 54 nucleotide long chains,
the number of probabilities that may be interpreted other
than what they really are significantly increases in a comparison
between the complete human and chimp genomes, which comprise
billions of nucleotides.
Evolutionists' puzzle
With the advent of comparative genomic
analysis, it has been a cliché for evolutionists to say that the genetic
analyses will be able to provide the final answer to the
question "What makes us human?", or in other words,
that all features of a human being could be accounted for
at the DNA level. The first comprehensive comparison of the
human and chimp genomes is in hand but it does not seem to
be of a clue, let alone provide an answer. This can be observed
in news accounts reporting the study. Robert Waterston, director
of genome sciences at the University of Washington and a
member of the consortium says:
[Genetically] We're not that different. But we have language,
cars, espresso machines and psychotherapy. How could all
that result from just a comparatively small number of genetic
changes in the overall blueprint? (6)
True. How can a small number of genetic
differences place the chimpanzees in a forest while putting
scientists, on the other hand, in a research consortium
to study the chimpanzee genome? Obviously, human beings,
who possess reason and feelings, cannot be reduced to genes.
This leaves evolutionists unanswered. Svante Pääbo
of the Max Planck Institute of Evolutionary Anthropology
in Leipzig, Germany, a co-author on one Nature paper is
reported as saying:
We cannot see in this why we are phenotypically so different
from the chimps. Part of the secret is hidden in there,
but we don't understand it yet. (7)
Collins, of the National Human Genome
Research Institute, points out that it is erroneous to
seek the answer to the question "What makes us human?"
merely at the molecular level:
"The real question about what it takes to be human
is more than a biological question, it's also a theological
question," Collins said. DNA
"may not tell us 'How do we know what's right and
wrong?' and 'What's the human spirit, anyway?'" (8)
What to understand from the Chimpanzee
Genome Project?
There is long way to go for a comprehensive understanding
of the human and chimpanzee genetics. This latest comparison
study has merely provided the scientists with raw data. As
Ajit Varki of the University of California, San Diego, puts
it:
[A] genome is like the periodic table
of the elements… By
itself it doesn't tell you how things work--it's the first
step along a long road. (9)
First of all, as a general principle, data does not speak
for itself; it is interpreted. Suppose that you are
asked whether a given blue cube looks more like a blue pyramid
or a bigger blue cube. Your answer will differ based on which
criterion you will choose; color or size. The point that
should be remembered about this study is that genetic differences
are much more complex than what the evolution propagandists
would have us believe by such descriptions as "99% similarity." Once
other types of genetic variations are taken into account,
this percentage significantly decreases. Yet, still, this
last interpretation too seems to be overshadowed by evolutionist
bias. An internationally respected biochemist Fazale Rana,
PhD, denies even the 96% similarity as follows:
[W]hat we are seeing here is a scientific
shell game… Researchers
are manipulating the outcomes to try and show more similarities
between chimps and humans than are actually there by focusing
on a single type of genetic difference. When scientists
take into account all the types of genetic differences
and do a more global comparison, the similarities drop
from 96% to about 85%. (10)
Secondly, we see once again that as there
is gain in scientific knowledge, evolutionists experience
loss. This is how the claims of vestigial organs and junk
DNA were abandoned. These claims were based on an erroneous
reasoning:
"We don't know their functions, so they must be functionless." With
the advance in scientific understanding of them, however,
it was understood that the evolutionist claims were severe
errors based on ignorance. The genetic similarity propaganda
is going through the same process today. Scientists now see
that the previous interpretations on genetic similarity were
based on a superficial, hasty, clumsy and deceptive approach.
Thirdly, and most importantly, a difference of 40 million
bases would fill 10,000 pages, if each base represented a
letter. (11) Believing
that such genetic difference accumulated as a result of nature's
unconscious forces and coincidences is like believing that
tens of thousands of random changes on the electronic edition
of a medical encyclopedia would add new information, transforming
it into an encyclopedia of physics rather than turning it
into a meaningless mass of letters.
The myth of evolution
The tale of the ape-like creature which descended from the
trees, adapted to a new habitat, gradually acquired new biological
features and eventually turned into a perfect human being
is the greatest nonsense of the modern culture. Interestingly,
however, genetic researchers seek for the traces of this
myth in the human and chimpanzee genomes, believing that
their own scientific minds are a product of coincidences
and purposeless natural phenomena. What logical reason could
there be to believe in this false faith coming from a mind
which tries to account for itself as a product of chemical
processes?
None, of course.
The theory of evolution is a deception concocted to uncover
the fact of creation. Humans and chimpanzees did not evolve;
they are perfect beings created by God, the Creator of all.
