“The Act does not grant teachers a flexibility that they did not already possess to supplant the present science curriculum with the presentation of theories, besides evolution, about the origin of life. Indeed, the Court of Appeals found that no law prohibited

Louisiana public schoolteachers from teaching any scientific theory... The Act provides Louisiana schoolteachers with no new

authority. Thus the stated purpose is not furthered by it.”

“We do not imply that a legislature could never require that scientific critiques of prevailing scientific theories be taught.

Indeed, the Court acknowledged in Stone that its decision forbidding the posting of the Ten Commandments did not

mean that no use could ever be made of the Ten Commandments, or that the Ten Commandments played an

exclusively religious role in the history of Western Civilization. In a similar way, teaching a variety of scientific theories about the origins of humankind might be validly done with the clear

secular intent of enhancing the effectiveness of science instruction.”

for various aspects of evolutionary theory. HS-ETS1-2 calls for students to “Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can

be solved through engineering.”

The origins controversy is an excellent tool to teach these standards.

IS INTELLIGENT DESIGN UNSCIENTIFIC?IS INTELLIGENT DESIGN UNSCIENTIFIC?Intelligent Design is a broad concept that allows for

the possibility of either direct creation or theistic evolution. Judges nationwide have bought into the

atheistic claim that since the presence of a designer cannot be tested, therefore I.D. is unscientific.

It is true that no scientific test can prove the existence of a designer. But the judges have overlooked an

obvious question: what sort of scientific test could prove there is NOT a designer?

In what way is teaching the IMPOSSIBILITY of intel-ligent design any more scientific than teaching the

POSSIBILITY of intelligent design?

to any religion’s concept of God. It does not tell us anything about the designer, so it does not

SPECIFIED IMPROBABILITYSPECIFIED IMPROBABILITYIn any collection of matter, no one arrangement is more or

less improbable than any other. (Somebody is probably going to win the lottery.)

However, this is not what the search for design is about. We are looking not just for improbability, but improba-

bility in a specific direction. (Is Mt. Rushmore an accident?

If the same person wins the lottery week after week, aren’t you going to get

suspicious?)In nature, most arrangements produce meaningless junk.

Only a few produce life. The question is, how improbable is it that those specific

arrangements could arise by chance?

Biologists often use statistical tests such as “chi-square” distribution and “t-tests” to determine whether a phenomenon seems to be random or non-random (e.g., location of ant hills along a levee). Yet many are unwilling to admit that

Intelligent Design is simply a reasonable application of probability testing to see if there are indications of non-randomness in nature.

The I.C. model does not make any predictions about the universe’s size. Since it started complex, it could be any age – some believe billions of years, others thousands. Either way, its steady deterioration means that it must

be young enough for stars not to have burned out, galaxies not to have flown apart, etc.

Students will understand that the universe’s size cannot be directly measured. They should know the steps used to calculate cosmic distances: parallax, Hertzsprung-Russell Diagram, Main Sequence method, Cepheid variable stars, Galactic Red Shifts, etc.

They should be made aware that these methods require 3-dimensional Euclidean geometry, while many big bang models require space to be 4-dimensional and non-Euclidean. (There is no center.)

They should understand that non-Euclidean space was introduced to deal with the observation that the Milky Way seems to be fairly near the center of the universe.

SIZE AND AGE OF THE UNVERSESIZE AND AGE OF THE UNVERSE

Students should understand what the red shift of starlight is, and be made aware that size calculations depend upon our being correct in interpreting red shifts as a Doppler effect.

They should learn that there are several alternate models as to what red shifts mean and why they exist, and learn the strengths and weaknesses of each model.

They should learn how astronomers deal with the quantization of red shifts, which some interpret to indicate that the Milky Way is fairly close to the center of the universe.

SIZE AND AGE OF THE UNVERSESIZE AND AGE OF THE UNVERSE

Students should learn what the terms “dark matter” and “dark energy” mean.

They should understand that these concepts were introduced because the distribution of matter and energy in the universe, galaxies, galaxy clusters and so on is not what it was expected to be for an extremely old universe.

If any evidence for dark matter or dark energy is ever discovered, students should learn what it is.

They should also learn of alternative models for the size and age of the universe that do not require these concepts.

Since life resulted from purely natural processes, we should find evidence that conditions on the early earth were suitable to produce life from lifeless chemicals - vastly different from the way things are now. We also expect that, under the right

conditions, life could again be produced from nonlife.

The first living things came into existence in a complex, fully functional condition. We expect to find evidence that from the

time these organisms first appeared, conditions on earth have been suitable to sustain life - probably not too dif-

ferent from the way things are now. We also expect to find life coming only from life.

Students should know the historical beliefs about spontaneous generation of life from decaying vegetation, rotting meat and the like (“abiogenesis”). They should be familiar with Pasteur’s and similar experiments disproving the spontaneous generation of life in this manner.

ORIGIN OF LIFEORIGIN OF LIFE

They should understand the Oparin-Haldane hypothesis, the most widely accepted scenar-io for the origin of life. It says the early atmo-sphere was made of hydrogen, methane, am-monia, and water vapor. This formed the “pri-mordial soup,” which was struck by energy sources such as lightning, ultraviolet, heat, or Stanley Miller’s apparatus used to test

the Oparin-Haldane Hypothesis (Denver Museum of Science – photo by the author)

shock waves. The chemical action formed amino acids, then proteins, and finally living cells.

Visual #53

Students should be aware of an alternative model known as “Directed Panspermia,” proposed by Nobel Prize winner Dr. Francis Crick. He believes that life began elsewhere in the universe, then came to earth. His reasoning will be very informative to their understanding of biological processes.

They should know that the chemical reactions of the Oparin-Haldane scenario do not occur in the presence of free oxygen. (Hence, it is excluded from experiments.)

They should know that oxidized deposits have been found in every layer of the earth’s geologic column, all the way down to basement rock. This indicates the presence of free oxygen on the early earth. Students should learn how adherents of the Oparin-Haldane hypothesis deal with this evidence.

the sun produces mainly long-wave, which is deadly to living cells. They should realize that the ozone layer, which filters out most of the long-wave UV before it can reach the earth’s surface, would not have existed at the beginning.

Amino acids make up proteins, which in turn compose cells. In lab experiments, they occur as a roughly even mixture of right-handed and left-handed forms. Students should learn how to use probability techniques to calculate the odds that every single one of the 24,000 or so amino acids in a cell would come out right-handed while every one of the 3 billion or so sugars in DNA is right-handed.

They should learn about any efforts of biologists to overcome the natural randomizing effects of chemical action, which prevent complex biological molecules from forming spontaneously apart from DNA.

DNA is needed to form enzymes and enzymes are needed to form DNA (a seemingly irreducibly complex system). Students should learn about any efforts of biologists to determine how DNA could have come into existence apart from enzymes.

Students should go beyond exploring the Oparin-Haldane Hypothesis to the next logical steps. If a cell could form, what would protect it from the environment? They should learn that a phospholipid membrane can form spontaneously because it is thermodynamically favorable.

They should understand that such a membrane does too good a job of protection, cutting off the cell from absorbing necessary nutrients such as phosphates from the surroundings.

They should learn that ion channels or permeasesallow needed substances in and out.

They should learn that these channels are placedexactly where needed, because of preexisting in-formation in DNA. They should understand that this is an irreducibly complex mechanism: ion channels are needed to form DNA, and DNA is needed to form ion channels.

The first living thing was a single cell that was far simpler than any known today. As it and its descendants reproduced, they experienced many copying mistakes (mutations) in their DNA. Many of these must have been beneficial. They created all the

genetic information found in every type of organism that has ever lived.

INITIAL DISORGANIZATION:INITIAL DISORGANIZATION:

INITIAL COMPLEXITY:INITIAL COMPLEXITY:There were many types of living things at the beginning. They began in a complex, fully functional condition. Changes would damage genetic information rather than adding to it. Mutations should be harmful, so there should be mechanisms to minimize

them. No new major types should have come into existence since the beginning, but many may have gone extinct.

Lamarckianism – use and disuse of body parts (e.g., the giraffe’s neck)

Industrial melanism – the Peppered Moth So-called vestigial organs Haeckel’s “embryonic recapitulation” fraud

Besides learning about what should not be part of the origins discussion, they will learn about what should. For example:

•They will learn about any proposed mechanisms for the multiple levels of error checking and correcting in the cell.•They will learn about the effects of mutations on DNA as well as proposed mechanisms that might have created new genetic information.

• The earth’s geologic features accumulated slowly and gradually. The great majority of fossils were produced by presently observed pro-cesses operating slowly and gradually over vast expanses of time.

• Most fossils form when an animal or plant dies near water, falls in, and is gradually covered by sediment.

INITIAL DISORGANIZATION:INITIAL DISORGANIZATION:

INITIAL COMPLEXITY:INITIAL COMPLEXITY:• Though natural processes usually proceed slowly and gradually, there may

have been times when they operated much faster. One or more catastrophic events may have accelerated the development of geologic features.

• Living things can turn into fossils rapidly after catastrophic events such as volcanic eruptions and floods. This and the fact that most fossils are found encased in water-laid sediment lead us to believe that much of the fossil record was produced in the aftermath of catastrophic events.

EDUCATIONAL ENHANCEMENT:EDUCATIONAL ENHANCEMENT: Students should learn about experiments that have produced

simulated fossils in a short time. They should become familiar with vast fossil graveyards found

around the world, as well as proposed uniformitarian explanations for them.

They should learn of modifications in geologic models that allow for the possibility of catastrophism.

They should study the phenomenon of strata occurring in a different order than predicted by uniformitarianism, and learn mechanisms (e.g., overthrusting) proposed to explain those exceptions.

They should study uniformitarian and catastrophic mechanisms proposed to explain orogenesis (mountain building).

From an educational perspective, it is not necessary for students to make up their

minds about whether creation or evolution makes more sense.

Instead, by stimulating their natural curiosity about this emotional topic, we teachers can help them develop the skills necessary to evaluate all sides of a controversial issue.

Isn’t that what good education is all about?
