So, Alu elements are mobile DNA modules that can exert diverse influences on genomes and the organisms harboring them. They can affect genome function in constructive ways, by altering gene expression or supporting chromosome structure. And they can be damaging, even deadly. There are more than a million of them in the human genome, and we don't know what each one does.

Christian unity is not something to take lightly. Famous biblical proof texts urge us to pursue it. Basic theological commitments establish it as a primary goal of believers. Basic human nature would seem to drive us to seek solidarity with those who share fundamental beliefs.

Last month, I read that Biologos (a Christian "think tank" that advances evolutionary creation) and Reasons To Believe (a Christian "think tank" that advances old-earth creationism) were reporting on a dialogue between their two organizations that was intended "to discuss areas of agreement and disagreement" with a particular focus on "the biological record of the past 700 million years." This is very interesting to me. My position

Wow, lots going on lately.1. So, what is a species? The concept is much abused by creationists, so that an already-challenging topic is turned into an abyss of confusion and obfuscation. John Wilkins is a philosopher of science who runs a superb blog over at ScienceBlogs, Evolving Thoughts.

Months ago, I was worrying about how to characterize creationist statements that are untrue or misleading. The claims in question are not merely false (mistakes of various kinds can generate falsehood) and are not statements of opinion with which I disagree. They are claims that are demonstrably false but have been asserted by people who are certain (or likely) to know this. In other words, they bear the marks of duplicity.

The sun came out this week and the temperature soared to almost 50. In Phoenix, such a temperature is called 'cold'; here, it inspired us to have a cookout, though it didn't happen because the snow and ice on the deck precluded access to the blessed Weber kettle. But tomorrow, we're there.And I've been back on my bike this week, dodging cell-phone-wielding buffoons driving alone in SUVs.

That's Tom de Kay, editor of the Home & Garden section of the New York Times. Last week Thursday, that section ran a story, "A Refugee from Gangland," describing the life of Margaret B. Jones, the author of a just-released "heart-wrenching memoir" set in gangland L.A. The Times piece is fascinating, and the memoir probably is too. One little problem: the memoir has just been revealed to be a fraud.

Can you tell which of the authors quoted above won a Pulitzer? Heh.Back to the big lie about "junk DNA" as told by anti-evolution propagandists. The first theme in this cesspool of creationist folk science, as I described in the first installment of this series on "junk DNA", is this: that "junk DNA" is functional and therefore that evolutionary claims regarding its origin are mistaken.

Now this is interesting. I can think of plenty of interesting Shakespearean scenes involving conflict and disputation. [Takes a bow] But I couldn't recall the word 'disagree' anywhere in, say, Hamlet or Romeo and Juliet, or even Macbeth.
