Evolution As Catch-All Explanation
June 3, 2009
If you were taught a precise definition of neo-Darwinism in school, it doesn’t seem to matter to many evolutionists in the media.  In practice, the word “Evolution” seems to act as a catch-all category for explaining anything and everything – whether or not random mutation and natural selection were involved.  Some purpose and design can […]

Milankovitch Cycles Indistinguishable from Randomness
June 2, 2009
A claim has often been made by geologists that the rock sediments record cyclical changes in Earth’s orbit.  Milankovitch cycles, named for the man who analyzed them, are a set of regular periodic changes to the orbital eccentricity, obliquity, and axial precession of the Earth over tens and hundreds of thousands of years.  These subtle […]

Grasses Ratchet Their Seeds Into Distance Travelers
June 2, 2009
John Muir said we should not pity plants as prisoners to one spot.  In their own ways, they travel the world as we humans do.  Anyone who has walked through wild dry grass may have been annoyed at how many foxtails get buried in their socks and how hard it is to get them out.  […]

You Can Trust a Scientist – Can’t You?
May 31, 2009
After the flap over the “missing link” Ida last week (05/19/2009), paleontologist Christopher Beard warned about how such stunts damage scientific credibility.  “The only thing we have going for us that Hollywood and politicians don’t is objectivity,” he told Science magazine.1  Can the public trust the objectivity of scientists as a class?  Do they get […]

Is Theistic Evolution Intelligently Designed?
May 29, 2009
A battle of websites is rising, and New Scientist is gloating.  Francis Collins, former head of the Human Genome Project (and a candidate to lead the National Institutes of Health) has launched a website promoting theistic evolution called Biologos.org.  The intelligent-design think tank Discovery Institute has offered a counter-site called FaithAndEvolution.org.     Amanda Gefter […]

Who Gets the Blame for This Oil Spill?
May 22, 2009
Who could forget the Exxon Valdez oil spill in 1989, that leaked 10.8 million gallons of oil into Alaska’s pristine coastal waters?  That mistake cost Exxon a billion dollars in damages for the ecological disaster it caused and sparked one of the biggest cleanup operations in history.  Imagine 80 times as much.  That’s how much […]

Building Planets: Can’t Make Them, But Hurry
May 21, 2009
Constructing planets is a delicate business.  Trying to get tiny bits of dust to join up into balls has never been found to work.  It has to work fast, though, because unless the whole planet clears its dust lane, it will be dragged into the star in short order.  It seems you can’t get there […]

Junk-DNA Stock Tumbles
May 18, 2009
Those investing credibility in the concept of “junk DNA” suffered more losses this week.  Repeated hits to the paradigm that portions of non-coding DNA are useless leftovers of evolution make a recovery unlikely.     In Science,1 researchers from Princeton and Indiana University reported a function for transposons and the genes that act on them, […]
