Republican lawmaker introduces bill to protect questioners of Darwinism

Excerpt:

An Arlington lawmaker has filed a bill aimed at protecting Texas college professors and students from discrimination because they question evolution.

The measure from Republican state Rep. Bill Zedler would block higher education institutions from discriminating against or penalizing teachers or students based on their research into intelligent design or other theories that disagree with evolution.

Zedler said he filed the bill because of cases in which colleges had been hostile to those who believe that certain features of life-forms are so complex that they must have originated from a higher power.

“We can have the academic freedom to have all kinds of ideas and philosophies but, lo and behold, even mention intelligent design and there are people that want to run you out of town on a rail,” Zedler said.

Zedler said fear of workplace discrimination is preventing evolution critics in colleges from speaking their minds.

“I do believe there are people that want to say something but … they’re afraid to because there are people around the country that have been discriminated against,” Zedler said.

Secular leftists place a great premium on getting “consensus” for whatever ideas provide maximum autonomy from moral obligations, whether the ideas are true or not. They don’t care whether the consensus is true, just that everyone agrees on it and that it produces good feelings. They just don’t handle differing points of view well… it confuses them and makes them anxious and frustrated. They are uncomfortable with concepts like being judged, or being punished. The don’t want anyone to disagree with their religion of materialism, which allows them to pursue pleasure apart from any objective moral obligations. Since the religion of materialism, which is so popular on the left, does away with morality, we have to be very careful to enshrine into the law protections for those who would dissent from this denial of objective morality. Otherwise you end up with cases like the Guillermo Gonzalez case or the Richard Sternberg case. There are no limits to what a materialist will do in order to keep up the illusion that no one is there to hold them accountable. They’ll believe anything. They’ll do anything. There isn’t anything in their materialism to stop them from committing atrocities. That’s why we need laws to contain their abuse of power.

A quotation from Martin Luther King, Jr. illustrates the point:

“It may be true that the law cannot make a man love me, but it can keep him from lynching me, and I think that’s pretty important.”

Until the time where those on the secular left learn to accept dissent, and allow debate, without resorting to insults and personal attacks, laws that protect dissenters will be necessary.

Jonathan Wells is interviewed about his new book on Junk DNA

1 Comment

Note to regular readers – don’t forget that the William Lane Craig vs. Lawrence Krauss debate is tonight at 7 PM Eastern time. And you can watch it online here. It is also being live-blogged here.

From Uncommon Descent. The interviewer is science journalist Denyse O’Leary.

Excerpt:

What caused the change of view about junk DNA? Can you suggest a couple of key findings?

In a word, evidence. The first to emerge was the fact that almost all of an organism’s DNA is transcribed into RNA. (So although most of it may be non-protein-coding, it codes for RNA.) From a Darwinian perspective, this is surprising: Why would an organism struggling to survive devote so many of its internal resources to producing supposedly useless RNA? Indeed, since 2003 it has become clear that non-protein-coding RNAs perform many essential functions in living cells.

Pseudogenes constitute one type of so-called “junk DNA.” These are segments of DNA that resemble segments that elsewhere (or in other organisms) code for protein. Yet RNAs transcribed from some pseudogenes have been found to function in regulating how much protein is produced by the DNA segments they resemble. Repetitive DNA, in which a non-protein-coding sequence is repeated many times, is another type of so-called “junk DNA.” Yet repetitive DNA is now known to regulate many essential functions, including embryo implantation in mammals.

There is also growing evidence that non-protein-coding DNA can perform functions that are independent of its sequence. One example is the region of a chromosome (called a “centromere”) that attaches it to other structures in the cell. Another example is the retina in the eyes of nocturnal mammals, in which non-protein-coding DNA acts like a liquid crystal to focus scarce rays of light.

Some claim that ID theorists predicted the finding and others claim they didn’t. What’s your take?

The literature doesn’t lie. Design theorist William A. Dembski wrote in 2004, “For years now evolutionary biologists have told us that the bulk of genomes is junk and that this is due to the sloppiness of the evolutionary process. That is now changing. For instance, researchers at the University of California at San Diego are finding that long stretches of seemingly barren DNA sequences may form a new class of noncoding RNA genes scattered, perhaps densely, throughout animal genomes. Design theorists should be at the forefront in unpacking the information contained within biological systems.” (The Design Revolution, p. 317.) At the time, biologists such as Dawkins, Coyne, Avise and Collins were still claiming that most of our DNA is junk.

Last week there was a paper in the peer-reviewed journal Science that discussed the problem of genetic similarities in different organisms that do not share a common inheritance. Evolution News talked about that here.

Stephen C. Meyer in FOUR John Ankerberg online videos

From Evolution News. (H/T Stephen C. Meyer)

Excerpt:

In four television episodes of the John Ankerberg Show broadcast across the US and over 200 nations worldwide, Dr. John Ankerberg interviewed Dr. Stephen C. Meyer, author of the groundbreaking book Signature in the Cell: DNA and the Evidence for Intelligent Design. The series will begin broadcasting on April 3 at 5:30pm EDT on the Daystar Network and on April 10 at 9:30pm EDT on the INSP Network.

In the interviews Dr. Meyer explains how even Charles Darwin, in his book The Origin of Species, admitted he did not know how the first cell came into being, or how life came to be.

Scientists in Darwin’s day thought the cell was a simple glob of plasm, but today we have discovered that the cell is an almost unimaginably complex system of molecular machines and rich in digital code.

Where did this high-tech in low life come from? Ankerberg and Meyer explore the mystery surrounding this question, which Meyer calls the DNA enigma. Click on the links below to watch full episodes of the show online!

  • Week 1: Every person’s body consists of over a trillion cells. Almost every one of these cells includes a DNA molecule. What is DNA? Why is it so special? What does it do? Where did the digital code embedded in DNA originate? Why does the specified information in DNA point to a designing intelligence?
  • Week 2: As scientific technology has progressed, scientists have realized the cell is more and more complex. According to Microsoft’s Bill Gates, the DNA within each cell is far more complex than any computer software ever created. Where did the coded information within DNA come from? What naturalistic theories have been proposed? What is the possibility of the precise genetic information in DNA evolving by chance?
  • Week 3: In addition to chance, scientists have offered other answers to the origin of the precise genetic information found in DNA. Why is it that natural selection, self-organizing natural laws, or some combination of these with chance cannot explain where the information originated? We’ll also see why DNA exhibits signs of a designing intelligence.
  • Week 4: What is the scientific theory of Intelligent Design (ID)? Is ID true science or just religion masquerading as science? We’ll also answer the objections to ID such as, “Is ID just an argument from ignorance?” (“We don’t know what the naturalistic causes are right now for the origin of life.”) We’ll also see why ID is based on scientific reasoning but may have larger religious implications.

And Meyer is not making this up. This is the state of science today.

Excerpt:

As recently as the middle of the 20th century, many scientists thought that the first organisms were made of self-replicating proteins. After Francis Crick and James Watson showed that DNA is the basis for genetic transmission in the 1950s, many researchers began to favor nucleic acids over proteins as the ur-molecules. But there was a major hitch in this scenario. DNA can make neither proteins nor copies of itself without the help of catalytic proteins called enzymes. This fact turned the origin of life into a classic chicken-or-egg puzzle: Which came first, proteins or DNA?

RNA, DNA’s helpmate, remains the most popular answer to this conundrum, just as it was when I wrote “In the Beginning…” Certain forms of RNA can act as their own enzymes, snipping themselves in two and splicing themselves back together again. If RNA could act as an enzyme, then it might be able to replicate itself without help from proteins. RNA could serve as gene and catalyst, egg and chicken.

But the “RNA-world” hypothesis remains problematic. RNA and its components are difficult to synthesize under the best of circumstances, in a laboratory, let alone under plausible prebiotic conditions. Once RNA is synthesized, it can make new copies of itself only with a great deal of chemical coaxing from the scientist. Overbye notes that “even if RNA did appear naturally, the odds that it would happen in the right sequence to drive Darwinian evolution seem small.”

The RNA world is so dissatisfying that some frustrated scientists are resorting to much more far out—literally—speculation. The most startling revelation in Overbye’s article is that scientists have resuscitated a proposal once floated by Crick. Dissatisfied with conventional theories of life’s beginning, Crick conjectured that aliens came to Earth in a spaceship and planted the seeds of life here billions of years ago. This notion is called directed panspermia. In less dramatic versions of panspermia, microbes arrived on our planet via asteroids, comets or meteorites, or drifted down like confetti.

John Horgan is not a Christian, nor even a theist. The origin of life is not explainable on the basis on unintelligent causes. But it is perfectly explainable as the result of intelligent causes. Just like the sequence of letters arranged in this blog post to have meaning are best explained as the result of an intelligence.
