The Elephant Explosion
June 30, 2009
The title is not intended to suggest pieces of pachyderm flying all over the place, but rather one paleontologist’s theory about the rapid pace of elephant evolution 60 million years ago.  He bases his ideas on a small fossil he found in Morocco.  According to him, the primitive ancestor of all elephants (order Proboscidea) lived […]

Dino Fossils Generate Overblown Claims
June 18, 2009
04/10/2006), inventing feathers out of thin air.  This time, it was justified on the basis of a new paper in Nature that claims to remove an obstacle in the dinosaur-bird evolution story.1  Doubters had pointed to differences in the three forward-pointing toes.  With dinosaurs, it was toes 1, 2 and 3 that were retained; while […]

Plants Use the Perfect Propeller
June 16, 2009
What kid hasn’t played with maple seeds to watch them spin in the air like helicopters?  Scientists watch them, too.  A team from the Netherlands and California found out how they stay in the air for so long without engines to drive them.  One would think in an era of advanced aeronautical engineering the physics […]

Birds Didn’t Evolve from Dinosaurs
June 9, 2009
June 9, 2009 — “The findings add to a growing body of evidence in the past two decades that challenge some of the most widely-held beliefs about animal evolution.”  That statement is not being made by creationists, but by science reporters describing work at Oregon State University that cast new doubt on the idea that […]

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 […]

Hominids, Homonyms, and Homo sapiens
May 27, 2009
How’s the story of human evolution hanging together these days?  There’s no better place to look than the Annual Review of Earth and Planetary Sciences.  In the yearly issue released this month, Ian Tattersall and Jeffrey Schwartz gave a pretty thorough overview of the “Evolution of the Genus Homo.”1  Their account is fraught with controversy, […]

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, […]

Survival of the Slowest
May 11, 2009
Without stopping to think, the BBC News claimed that evolution is slowing snails down.  “Natural selection is favouring snails with reduced metabolic rates, researchers in Chile have discovered.”  Why would evolution do such a thing?  Isn’t the proverbial slowest of beasts already at risk of predators?  Not necessarily.  Look on the positive side: “Snails with […]

High School Biology Teachers Have Clout
May 8, 2009
Two professors at Minnesota State surveyed a thousand students on the impact of their high school biology teachers when it comes to the subject of evolution or creation: Students whose high school biology class included creationism (with or without evolution) were more likely to accept creationist views as entering college students.  Similarly, students exposed to […]

The Long Precambrian Fuse Gets Longer
April 28, 2009
Why did complex multicellular life explode on the scene some 550 million years ago?  That’s mystery enough, but finding complex single-celled life a billion years earlier makes it worse.  A new paper evaluated claims of Cambrian-like fossils from India dated 1.6 billion years old in the evolutionary timeline.  It did not explain the Cambrian explosion, […]

How Valid Is Computerized Dinosaur Reconstruction?
April 18, 2009
Can you reconstruct a dinosaur on a computer?  Of course you can.  The question is how accurate it reflects something no one has ever seen.  Live Science told about Peter Falkingham at the University of Manchester who is using “genetic algorithms” and simulating evolution to figure out how dinosaurs walked.     A dinosaur’s gait […]

Is Horizontal Gene Transfer a Force for Evolution?
April 13, 2009
Two more genomes were published last week: the information libraries of two tiny microbes.  They are members of Micromonas, green algae less than two microns across.  The original paper and summary both bragged about how the genetic information is helping shed light on evolution, but did the data really contain any light?  If so, the […]

Animal Flight Control: Where’s the Evolution?
April 12, 2009
A couple of articles in Science last week discussed the marvels of flight control in birds.  “Being earthbound save for the ability to fly airplanes and helicopters, humans stand in awe of animals that power their own movement through the air by flapping their wings, and of the spectacular maneuvers that some of these animals […]

Can Evolution Be Programmed?
April 6, 2009
Some researchers are employing “evolutionary computing” as an algorithm to solve problems.  But is it really evolution? Evolved machines:  A company called Evolved Machines in Palo Alto announced a 40-teraflop machine that will be used for the “artificial evolution of neural circuitry” (see press release on United Business Media).  “It is self-evident that in biological […]

Evolutionists Tell Us What Nature Intended
April 3, 2009
Can nature intend anything?  A true materialist lacks access to the concept of purpose and intentionality.  Whatever is, is.  Nevertheless, some staunch evolutionists avail themselves of the purpose-driven life by telling us what evolution intended.     Meredith Small tells us on Live Science, for instance, that nature did not intend single parents.  Having become […]
