Jonathan Wells is interviewed about his new book on Junk DNA

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.

Brown University students attack pro-marriage sign at demonstration

Story from Christian Newswire.

Excerpt:

Volunteers from the American Society for the Defense of Tradition, Family, and Property (TFP) visited Brown University during their state-wide tour for traditional marriage in Rhode Island. While peacefully demonstrating on the Ivy League campus, their pro-family banner was vandalized and a volunteer was spat upon in the face.

“What we faced at Brown University, an Ivy League university, had the flavor of a religious persecution,” said TFP Student Action Director John Ritchie. “Dozens of pro-homosexual students screamed, spat, taunted, and even attempted to destroy our traditional marriage banner.”

“Suddenly, a loud thud-rip noise was heard. I looked up and saw a pro-homosexual student literally crashing through our traditional marriage banner, attempting to destroy it,” explained Ritchie. “Running at top speed, he flung himself into it and ripped one side loose. Some students watching from a distance approvingly cheered the act of violence,” he said.

“Brown University students recently held a protest against traditional marriage at the same location where we held ours and their signs included the word ‘equality,'” Ritchie said. “However, they clearly wanted to impede our right to equally assemble.”

“One of our youngest volunteers, age 17, was spat upon in the face,” explained Ritchie. During our peaceful demonstration for God’s marriage, he walked over and asked: ‘What do I do with this on my face?’ First, we told him to wipe the spittle off his face and then reported the incident to the police.”

“Seeing the violent attitude of the pro-homosexual students, the police wanted to escort us to our vans after the campaign was over to protect us,” stated Ritchie. “And thank God they did, because when we pulled away from the curb, many pro-homosexual students closed in to hit the sides of our vehicles with their fists or palms. A hard object, maybe a rock, was even thrown against one of the vans.”

I would link to the video, but Youtube has censored it. Youtube is not what you would call a pro-free speech web site.

I admire anyone who is willing to stand up for the rights of children to have a mother and a father to grow up with.

Obama covers 44 million more Americans under Disabilities Act

Excerpt:

Millions of Americans may be disabled and not even know it, according to some legal experts.

That’s because sweeping new regulations from the Equal Employment Opportunity Commission offer new guidelines on the issue of how to define “disability” under the Americans with Disabilities Act.

The ADA, originally passed in 1990 and updated by Congress in 2008, originally defined disability as “a physical or mental impairment that substantially limits a major life activity.”

When a worker satisfies the definition, employers must provide reasonable accommodations. For years, employers and employees have clashed over who truly qualifies for the sometimes-costly modifications to workplace duties and schedules. Attorney Condon McGlothlen says the new regulations could have a profound impact on that debate.

“Before, perhaps 40 million people were covered by the ADA. That number will increase significantly,” McGlothlen told Fox News. “Some people might even say that a majority of Americans are covered as disabled under the law.”

His solution to unpopularity due to excessive spending is more excessive spending. When will he learn?
