Breakthrough Of The Year: Evolution In Action

30th December 2005

BREAKTHROUGH OF THE YEAR:
Evolution in Action
by Elizabeth Culotta and Elizabeth Pennisi

Excerpts:
Today evolution is the foundation of all biology, so basic and all-pervasive that scientists sometimes take its importance for granted. At some level every discovery in biology and medicine rests on it, in much the same way that all terrestrial vertebrates can trace their ancestry back to the first bold fishes to explore land. Each year, researchers worldwide discover enough extraordinary findings tied to evolutionary thinking to fill a book many times as thick as all of Darwin’s works put together.

Amid this outpouring of results, 2005 stands out as a banner year for uncovering the intricacies of how evolution actually proceeds. Concrete genome data allowed researchers to start pinning down the molecular modifications that drive evolutionary change in organisms from viruses to primates. Painstaking field observations shed new light on how populations diverge to form new species–the mystery of mysteries that baffled Darwin himself. Ironically, also this year some segments of American society fought to dilute the teaching of even the basic facts of evolution. With all this in mind, Science has decided to put Darwin in the spotlight by saluting several dramatic discoveries, each of which reveals the laws of evolution in action.

One of the most dramatic results came in September, when an international team published the genome of our closest relative, the chimpanzee. The genome data confirm our close kinship with chimps… the total difference in DNA between our two species [is] about 4%.

2005 was also a standout year for researchers studying the emergence of new species, or speciation. A new species can form when populations of an existing species begin to adapt in different ways and eventually stop interbreeding. . . . This year field biologists recorded compelling examples of that process, some of which featured surprisingly rapid evolution in organisms’ shape and behavior.

Such evolutionary breakthroughs are not just ivory-tower exercises; they hold huge promise for improving human well-being. . . . Humans are highly susceptible to AIDS, coronary heart disease, chronic viral hepatitis, and malignant malarial infections; chimps aren’t. Studying the differences between our species will help pin down the genetic aspects of many such diseases. . . . And in 2005, researchers stepped up to help defend against one of the world’s most urgent biomedical threats: avian influenza. . . . The possible evolution of [an ability to infect humans] in the bird flu now winging its way around the world is why officials worry about a pandemic today.

Evolution of the Immune System

30th December 2005

Immunology: Jawless Fish Have Form of Adaptive Immunity, Science Next Article
Excerpts:

Evolution doesn’t like to do things just once. It came up with flight three times, for example–in insects, birds, and bats. Now it appears that evolutionarily distinct immune systems have exploited a similar genetic trick to battle microbes. New research on page 1970 reveals that the immune defenses of jawless fish such as lampreys generate as much diversity as the immune system that organisms from sharks onward in evolution use. And both employ a similar technique: rearranging DNA.

The immune system in sharks, mammals, and other jawed vertebrates generates antibodies–proteins that recognize very specific molecular features of invading pathogens–by rearranging DNA segments and inducing random mutations to give rise to a hundred million million different possible proteins. This allows the immune system to adapt to each new infectious agent by boosting production of antibodies specific for the attacking microbe.

Researchers don’t yet know whether the lamprey’s immune system arose before our own or if it spun off from its own evolutionary tangent, but they’re impressed by its sophistication. “It’s just fascinating that there’s another adaptive immune system,” says David Davies of the National Institute of Diabetes and Digestive and Kidney Diseases in Bethesda, Maryland, who studies Toll-like receptors, other immune proteins that recognize pathogens.

Whether vertebrates started out with a [lamprey-like] system and later gave it up for the antibody-based immunity is anybody’s bet. The study authors are looking both in invertebrates–squid and octopus–and in bony fish for remnants of such a system. “It may well be that this exists in us because nature very rarely throws things away,” says Davies.

Judge Jones finds that “intelligent design” is not science

25th December 2005

Judge John E. Jones has issued his ruling in the Kitzmiller v Dover trial in Harrisburg, PA. It reads in part:

In the section concerning whether ID is Science:
After a searching review of the record and applicable caselaw, we find that while ID arguments may be true, a proposition on which the Court takes no position, ID is not science. We find that ID fails on three different levels, any one of which is sufficient to preclude a determination that ID is science. They are:
(1) ID violates the centuries-old ground rules of science by invoking and permitting supernatural causation;
(2) the argument of irreducible complexity, central to ID, employs the same flawed and illogical contrived dualism that doomed creation science in the 1980’s; and
(3) ID’s negative attacks on evolution have been refuted by the scientific community. As we will discuss in more detail below, it is additionally important to note that ID has failed to gain acceptance in the scientific community, it has not generated peer-reviewed publications, nor has it been the subject of testing and research.

From the conclusion:
The proper application of both the endorsement and Lemon tests to the facts of this case makes it abundantly clear that the Board’s ID Policy violates the Establishment Clause. In making this determination, we have addressed the seminal question of whether ID is science. We have concluded that it is not, and moreover that ID cannot uncouple itself from its creationist, and thus religious, antecedents.

Both Defendants and many of the leading proponents of ID make a bedrock assumption which is utterly false. Their presupposition is that evolutionary theory is antithetical to a belief in the existence of a supreme being and to religion in general. Repeatedly in this trial, Plaintiffs’ scientific experts testified that the theory of evolution represents good science, is overwhelmingly accepted by the scientific community, and that it in no way conflicts with, nor does it deny, the existence of a divine creator.

To be sure, Darwin’s theory of evolution is imperfect. However, the fact that a scientific theory cannot yet render an explanation on every point should not be used as a pretext to thrust an untestable alternative hypothesis grounded in religion into the science classroom or to misrepresent well-established scientific propositions.

The citizens of the Dover area were poorly served by the members of the Board who voted for the ID Policy. It is ironic that several of these individuals, who so staunchly and proudly touted their religious convictions in public, would time and again lie to cover their tracks and disguise the real purpose behind the ID Policy.

With that said, we do not question that many of the leading advocates of ID have bona fide and deeply held beliefs which drive their scholarly endeavors. Nor do we controvert that ID should continue to be studied, debated, and discussed. As stated, our conclusion today is that it is unconstitutional to teach ID as an alternative to evolution in a public school science classroom.

Those who disagree with our holding will likely mark it as the product of an activist judge. If so, they will have erred as this is manifestly not an activist Court. Rather, this case came to us as the result of the activism of an ill-informed faction on a school board, aided by a national public interest law firm eager to find a constitutional test case on ID, who in combination drove the Board to adopt an imprudent and ultimately unconstitutional policy. The breathtaking inanity of the Board’s decision is evident when considered against the factual backdrop which has now been fully revealed through this trial. The students, parents, and teachers of the Dover Area School District deserved better than to be dragged into this legal maelstrom, with its resulting utter waste of monetary and personal resources.

To preserve the separation of church and state mandated by the Establishment Clause of the First Amendment to the United States Constitution, and Art. I, § 3 of the Pennsylvania Constitution, we will enter an order permanently enjoining Defendants from maintaining the ID Policy in any school within the Dover Area School District, from requiring teachers to denigrate or disparage the scientific theory of evolution, and from requiring teachers to refer to a religious, alternative theory known as ID. We will also issue a declaratory judgment that Plaintiffs’ rights under the Constitutions of the United States and the Commonwealth of Pennsylvania have been violated by Defendants’ actions.

Defendants’ actions in violation of Plaintiffs’ civil rights as guaranteed to them by the Constitution of the United States and 42 U.S.C. § 1983 subject Defendants to liability with respect to injunctive and declaratory relief, but also for nominal damages and the reasonable value of Plaintiffs’ attorneys’ services and costs incurred in vindicating Plaintiffs’ constitutional rights.

NOW, THEREFORE, IT IS ORDERED THAT:
1. A declaratory judgment is hereby issued in favor of Plaintiffs pursuant
to 28 U.S.C. §§ 2201, 2202, and 42 U.S.C. § 1983 such that
Defendants’ ID Policy violates the Establishment Clause of the First
Amendment of the Constitution of the United States and Art. I, § 3 of
the Constitution of the Commonwealth of Pennsylvania.
2. Pursuant to Fed.R.Civ.P. 65, Defendants are permanently enjoined
from maintaining the ID Policy in any school within the Dover Area
School District.
3. Because Plaintiffs seek nominal damages, Plaintiffs shall file with the
Court and serve on Defendants, their claim for damages and a verified
statement of any fees and/or costs to which they claim entitlement.
Defendants shall have the right to object to any such fees and costs to
the extent provided in the applicable statutes and court rules.

CRUCIAL EVIDENCE LEFT OUT AT COBB COUNTY APPEAL, SAYS GEORGIA SCIENCE ADVOCACY GROUP

GCISE (Georgia Citizens for Integrity in Science Education) consists of parents, clergy members, K-12 faculty, higher education faculty, and other concerned citizens. GCISE is committed to improving science education in the state of Georgia, and therefore is deeply concerned about inaccuracies in the scientific information and legal evidence discussed at the 11th Circuit Federal Appeals Court today. We hope to educate the public on this matter in advance of the Courts ruling.

An erroneous conclusion was drawn in court today that the evolution disclaimer stickers were placed in Cobb science textbooks before parental complaints about the evolution content. As reported on 3/29/2002 by the Atlanta Journal Constitution however, the Cobb County School Board received complaints about new biology textbooks at a very contentious public school board meeting on 3/28/2002. During that meeting Cobb parent Marjorie Rogers informed the board that she had a petition signed by 2,300 people “dissatisfied with science texts that espouse ‘Darwinism, unchallenged.’” It was reported at that time that the Board would appease these parents by asking their lawyers to draft disclaimers “caution[ing] students that evolution is only a theory.” The Board testified in federal district court that they were addressing concerns from a group of conservative Christian parents with objections to teaching evolution.

To make matters worse, it was abundantly clear that confusion still reigns in Georgia about the meaning of the terms “theory” and “fact” as used by scientists. The National Academy of Sciences, organized by President Lincoln in 1863 to advise the nation on scientific matters, defines a scientific fact as “an observation that has been repeatedly confirmed.” Furthermore, they define a scientific theory as “a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.” With these definitions in mind, biological evolution can be considered both a fact and a theory. The readily observable “Fact” of Evolution is that populations of organisms change over time. Even creationist think tanks are on record accepting this idea. For example, no one denies that bacteria are rapidly evolving resistance to antibiotics and insects to pesticides. The “Theory” of Evolution uses several natural mechanisms including natural selection to explain quite well how the fact of evolution has occurred. Contrary to statements made in Court, evolution is probably our most thoroughly validated scientific theory, with hundred of years of supporting evidence.

Finally, the disclaimer sticker placed in Cobb textbooks calls evolution a theory about “the origin of life.” This is incorrect and makes the sticker extremely misleading to students. Evolution does not explain the origin of life on earth; it explains how that life has changed over the millennia since its origin. Thus the sticker is incorrectly representing scientific understanding.

Our children deserve complete, scientifically accurate textbooks, unadulterated by politically motivated, obfuscating messages. The success of Georgia students in college and in a global economy depends on science literacy. GCISE pledges our full support to parents and teachers wishing to provide the best possible education in modern science for their students.

Appeals judges skeptical about Cobb ruling

16th December 2005

AJC: Appeals judges skeptical about Cobb ruling

The 11th U.S. Circuit Court of Appeals is not expected to rule until next year, but the three judges’ skeptical questioning indicated they may be poised to side with the Cobb school board in the now-famous sticker case. Earlier this year, U.S. District Judge Clarence Cooper found that the stickers, which say evolution is a “theory, not a fact,” improperly endorsed religion.

Judge Ed Carnes, who dominated the questioning, said the three-sentence disclaimer seemed to him to be “literally accurate.”

Carnes took issue with Cooper’s finding that a petition with 2,300 names opposing the purchase of new biology textbooks with evolution instruction had been presented to the board before it agreed to place stickers on the books in March 2002. The court record indicates the petitions were presented to the board six months later, in September 2002, Carnes said.

At the end of the arguments, Carnes took the highly unusual step of calling Atlanta lawyer Jeffrey Bramlett, who argued on behalf of parents who filed suit against the stickers, back to the podium before the packed courtroom. Carnes suggested that Bramlett may have misled the court in his legal brief on exactly when the petitions where presented to the school board. Bramlett was told to write a letter to the court explaining how the confusion occurred.

But Carnes may have been misinformed by an incomplete trial record. On March 29, 2002, the day after the school board agreed to affix the stickers to science textbooks, The Atlanta Journal-Constitution reported Marjorie Rogers told the board she had collected petitions signed by 2,300 people who were dissatisfied with the new science texts.

In an interview after Thursday’s court hearing, Rogers, a self-avowed six-day biblical creationist, said she gave the petitions to the board before it decided to buy new science books with chapters on evolution.

“There wouldn’t have been any reason to give it to them in the fall,” she said. “They were done to try and persuade them not to buy the books.” One of the petition’s three options, she said, was for the board to put disclaimers in the new books.
