1. What are the basic principles of
science that apply to the study of biological origins?
The
basis of scientific inquiry and the means by which science
establishes reliability in its findings is evidence derived from
observations and experiments made in the material world.
Observations and experiments provide the connection between
abstract scientific theories, principles, and laws and the actual
behavior of the natural world. Observation is what grounds
scientific findings in reality.
Science
seeks to discover natural causes to provide natural explanations
for what is observed in nature. However, to say that natural
causes are the only causes or to dogmatically assert that
everything about the material world can be explained through
material causes alone are philosophical statements and not
objective statements about scientific methodology.
Science makes no presuppositions about the existence or
non-existence of transcendent causes.
Neither does science make any presuppositions regarding the
influence or effect a transcendent cause might have in the
material world or the ability or inability of science, using the
methods of empirical science, to detect those influences or
effects. Consequently,
the impossibility of disproving the existence of a transcendent
cause precludes an assumption that all observable effects must be
due to natural causes and only natural causes.
Imposition of such an assumption can only be made on the
basis of ideology and within the context of public education, raises
First Amendment issues.
Evidence
bearing on a scientific question must be critically examined
from all sides and evaluated on the basis of scientific merit, not
religious or philosophical presuppositions.
While it may be true that science can only study material
effects in the natural world, there are some effects that cannot
be explained by the laws of physics and chemistry, chance and
time alone and point to the possibility of an intervening
intelligence, or, a previously undiscovered law that mimics the
actions of an intervening intelligence. To rule out the
possibility of an intervening intelligence can only be made on
the basis of ideology, not evidence.
The
mindset of the scientist is cautious skepticism...a willingness to
accept an idea but only when presented with reliable and
convincing evidence. No theory of science is exempted from
critique...including evolution. When critique stops,
science stops (Thomas Huxley).
Reproducibility
and repeatability of experiments are essential to the process of
formally adopting a proposed hypothesis as an accepted theory of science.
2. What is the
difference between microevolution and macroevolution?
Microevolution
is the variation commonly observed within species and is an
observed fact. Examples are the development of antibiotic
resistance by bacteria or variations in some physical
characteristic of a species. A popular example is the observation
that the average length of the beaks of finches of the Galapagos
Islands increased slightly when the islands experienced severe
drought conditions.
When
biologists use the term macroevolution they are referring to
large-scale biological adaptations and innovations such as
development of feathers, wings, avian lungs and all of the other
anatomical features necessary for flight from a earlier forms that
had no such features or capabilities.
Microevolution
addresses the question of why the length of finch beaks might
change while macroevolution addresses the question of where
finches and their beaks come from in the first place. Science teachers
must be careful to make that distinction.
Darwin
hypothesized that the microevolutionary process could be
extrapolated to account for macroevolutionary change.
Mainstream scientists now doubt this.
3. Has science shown
that macroevolution is fact?
Science
takes the position that macroevolution is undisputed fact and
insists that it be taught as such in public schools. However,
macroevolution has never been observed...not in the laboratory and
not in the wild...and scientists plainly admit in the mainstream
scientific literature that the microevolutionary processes
observed in living populations cannot explain the large scale
biological changes and adaptations hypothesized to have taken
place in the past.
In
addition, science has not identified even a remotely plausible
mechanism for explaining the diversity and complexity of life.
Many scientists are skeptical of the ability of natural
selection to account for the complexity and diversity of life.
Macroevolution
may have taken place in the past as claimed, however, it has never
been observed and because it has never been observed, there is no
basis for claiming that it is fact and it should not be presented
as such in public schools.
4. What is the difference
between the historical sciences and the experimental sciences?
The
development of modern theories of physics and chemistry are based
on experimental science where scientists can make direct
observations in nature of cause-and-effect relationships as they
take place and conduct experiments under controlled conditions to
test hypotheses proposed to explain their observations.
The
study of biological evolution is unique in some respects in that
present life, which is directly observable, is the result of an
unobserved history.
Thus,
the study of historical events and processes introduces special
problems for scientists because the events and processes
themselves cannot be directly observed and experiments cannot be
conducted to evaluate hypothesized cause-and-effect relationships.
In the historical sciences, scientists have to work with the
"scraps" of history...the "leftovers"...in
their attempts to reconstruct a historical narrative of unobserved
past events and processes. Evolution, because of its
historical nature, is inherently subjective, cannot in principle
be reliably established with a high degree of confidence
and is highly vulnerable to religious or philosophical bias.
5. Does the
fossil record support macroevolution?
In
Darwin's day it was well known that the fossil record presented
serious challenges to his ideas about slow gradual changes and
innumerable intermediates. Darwin expressed his hope that further
discovery would fill in the missing intermediates. After almost
150 years
of searching the rocks, the situation is worse, not better.
The
problems with the fossil record, such as the sudden appearance of
the great variety of Cambrian animals in the Burgess Shale
followed by progressive major extinction of most of the Burgess
animals, is not a prediction of evolution by natural selection.
Sudden appearance of fully formed species with no apparent
ancestors, followed by stasis and extinction are, according to
leading paleontologists such as Stephen J. Gould, Niles Eldredge,
Colin Patterson, and Robert Carroll, the dominant features of the
fossil record. Only by incorporating a superficial selective
examination of the data (as is typically done in high school
biology textbooks) can the fossil record be reconciled to Darwin's
predictions. (See Stephen J. Gould, Wonderful
Life, 1989, P. 59; Douglas Futuyma, Evolutionary
Biology, Third Edition, 1998, p. 710; and Robert Carroll,
Patterns and Processes of Vertebrate Evolution, Cambridge
Paleobiology Series, Cambridge University Press, 1998, p. 1-18).
In
the preface and first chapter of his book,
Patterns and Processes of Vertebrate Evolution, Carroll makes
some extraordinary statements about pervasive problems in the
history of life constructed from examination of the fossil record
compared to the history predicted by Darwin. He even criticizes
textbooks for perpetuating this false history. Here is Carroll..
Instead
of showing gradual and consistent change through time, the major
lineages appear suddenly in the fossil record, already exhibiting
many of the features by which their modern representatives are
organized.
Few fossils are yet known of plausible
intermediates between the invertebrate phyla, and there is no
evidence for the gradual evolution of the major features by
which the individual phyla or classes are characterized.
Progressive increase in knowledge of the
fossil record over the past hundred years emphasizes how wrong
Darwin was in extrapolating the pattern of long-term evolution
from that observed within populations and species.
Biology
text books will usually say little about the fossil record but
what is said will skirt these issues while being careful to leave
the impression that macroevolution is supported by the fossil
evidence.
Whatever
may have happened in the past, the history of life revealed in the
dominant features of the fossil record does not reflect Darwin's
universal common ancestry descent model of that history or
natural selection as a dominant - rather than incidental -
mechanism for change.
6. Can Creation
Science be taught in public schools? What about intelligent
design?
The two most important cases
concerning the teaching of origins science were the Supreme Court
cases of Epperson v. Arkansas, 393 U.S. 97 (1968) and Edwards v.
Aguillard, 482 U.S. 578 (1987). There are perhaps a dozen or more
other lower court cases that also bear on origins science
education. Edwards is probably the principal case for determining
current legal precedent regarding the First Amendment and public
education. (This commentary does not consider the 2005
Kitzmiller case.)
In
Edwards the 7-2 majority struck down a Louisiana statute calling
for balanced treatment of Creation Science and Evolution Science
in public education. The essence of the Louisiana statute was that
no school was required to teach either theory but if one was
taught, both had to be taught. The rationale supporting the Court
findings is tangled and complex but the end result was that the
statute was struck down on the basis that it was in violation of
the Establishment Clause of the First Amendment. Basically, the
Court concluded that teaching of any theory of science in public
schools that is rooted in a religious source or doctrine
constitutes promotion of religion.
The
principle findings of Edwards were important and viewed as a great
victory for evolution in that the ruling was accompanied by the
perception that evolutionary theory had in effect been endorsed by
the highest court in the land. However, in the process of throwing
out the Louisiana statute, the Court also elaborated extensively
on its opinion regarding the meaning and intended effect of First
Amendment Law for public education.
Two
important findings of the courts that bear on the current issues
in science education in New Mexico are summarized as follows:
(1)
With respect to religious and philosophical views, strict
neutrality must be enforced in public education.
"
Government in our democracy, state and nation, must be neutral in
matters of religious theory, doctrine, and practice. It may not be
hostile to any religion or to the advocacy of no-religion; and it
may not aid, or foster or promote one religion or religious theory
against another or even against the militant opposite. The First
Amendment mandates government neutrality between religion and
religion, and between religion and non-religion." ( Epperson
v. Arkansas )
The
requirement for constitutional neutrality prohibits a
state-sponsored ideology of any kind... religious or otherwise.
(2)
The religious or philosophical implications of a theory of
biological origins are irrelevant to its legal status under the
First Amendment.
"
...a decision respecting the subject matter to be taught in public
schools does not violate the Establishment clause simply because
the material to be taught 'happens to coincide or harmonize with
the tenets of some or all religions.' " ( Edwards quoting
lower court rulings).
Thus
it appears that the religious implications of intelligent design
simply do not bear upon its constitutionality. And the
anti-religious implications of evolution do not bear upon
evolution's constitutionality. With regard to implication, it
appears that it is constitutionally permissible to teach both in
public education.
Because
Creation Science in rooted in a religious source and doctrine, it
has been declared unconstitutional. Perhaps one day a future court
will discover that evolution is rooted in ideology and declare
that it is unconstitutional as well. Intelligent design was
recently tested in the 2005 Kitzmiller case which ruled that
Intelligent Design was religion and to teach it in public
schools would be in violation of the Establishment Clause of the
First Amendment. For commentary on Kitzmiller, go
[here].
Legal scholars have found nothing in
Edwards v. Aguillard that would prohibit its teaching in public
education.

7. Can chemical
evolution account for the origin of life?
While
official science tells the public an optimistic story about origin
of life research, the truth is that 50 years of research is at a
dead end. No one knows how the first living cell came into
existence. Appropriately, "origin of life" is not
addressed in the New Mexico 2003 Revised Science Standards.
8. Can Darwin's
theory of natural selection account for the diversity of life?
There
is no convincing evidence that it can and there are no
observations that have been made in the natural world of large
scale biological changes or undisputed speciation events above the
species level. While the scientific establishment will generally
tell students and the public that natural selection, along with
"other mechanisms", can account for the diversity of
life and all of the biological adaptations observed in nature, the
mainstream scientific literature admits that science does not have
a naturalistic explanation for macroevolutionary change and
adaptation.
