Sexual Selection Discounted in Toucan Bill
July 28, 2009
Darwin thought that the large bill of the toucan might be an ornament produced by his theory of sexual selection.  A new study says, rather, that the bill serves as a heat radiator the bird uses to control body temperature.  National Geographic News summarized a paper in Science that explained the process.1  The authors studied […]

How the Animals Learned to Count
July 6, 2009
Any evolutionary article that begins with “How…” should be checked for Kipling-style just-so storytelling.  Characteristics to watch for include (1) fanciful speculation without evidence: i.e., “made-up” tales that provide an answer to a childish question without appeal to rigorous proof, and (2) statements made with dogmatic authority, like a parent would explain to a child […]

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 […]

Fighter Jet of the Animal World
June 10, 2009
A male hummingbird in its aerial display achieves speeds proportionally faster than a jet fighter with its afterburners on, reported the BBC News – and that’s on nectar and wings, without jet fuel.  The tiny birds even resemble top-gun fighter jets in the pictures accompanying the article.     It took a camera shooting 500 […]

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 […]

Another Crow Species Impresses Scientists with Tool-Making Skills
May 26, 2009
Who would have thought that crows rival chimpanzees in intelligence?  Members of the corvid group, which includes crows and ravens, are amazing researchers with their ability to make tools.     Previous studies with New Caledonian crows (08/09/2002, 10/07/2007, 02/23/2007) impressed researchers with the birds’ abilities to fashion simple tools out of available materials to […]

Cool Bird Tricks
May 19, 2009
Evidence continues to mount that a lot of capability is packed into a little bird’s brain.  We should use the phrase bird-brain to honor smart animals. I C U:  Mockingbirds can recognize individual humans.  Disturb a mockingbird nest, and the parents will single you out from a crowd and go into attack mode, researchers at […]

Is Darwinism Useful Explaining Cognition?
April 15, 2009
One would think the evolution of mind involves a straightforward account of improving cognition as one progresses up the evolutionary tree.  It’s not so simple, said two researchers in a Nature essay:1  Darwin’s theory of evolution by natural selection is broadly accepted among biologists, but its implications for the study of cognition are far from […]

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 […]

Amazing Fossils: Do They Help Darwin?
March 19, 2009
Some remarkable fossils have been found recently.  According to the reports, scientists are not sure what to make of them, even though evolutionary language is liberally applied to the interpretation. Octopus:  The earliest fossil octopus is 100% octopus.  A rare well-preserved octopus fossil, as unlikely as finding a fossilized sneeze according to Live Science, shows […]

Songbirds Sing on a Fast Wing
February 17, 2009
Purple martins and wood thrushes are common songbirds of the eastern United States.  Until recently, it has not been possible to follow their movements accurately.  Now, a team of biologists in Toronto, Erie and Cambridge was able to track them with tiny geolocators.  They found that the little birds fly farther and faster than previously […]

The Early Bird Gets the Just-So Story
February 3, 2009
If a catastrophic world event wiped out the dinosaurs, why did birds survive?  They’re smaller and more delicate, it seems.  National Geographic published a new hypothesis: they out-thought the doomed dinosaurs.  “Birds survived the global catastrophe that wiped out their dinosaur relatives due to superior brainpower, a new study suggests.”     A couple of […]

Is Natural Selection Losing its Appeal?
January 28, 2009
Some recent science reports sound like they are ready to cast Darwin’s key phrase natural selection overboard, or at least demote it from its leading role in evolution.  These articles each hint that long-held beliefs are being challenged. Make room:  Science Daily asked, “Natural Selection Not The Only Process That Drives Evolution?”  Scientists at Uppsala […]

Exploring the Malleability of Evolutionary Explanation

Is evolutionary theory just a very malleable and ductile idea, able to adapt to changing observations, or should it be described as a strong theory, powerful in its explanatory breadth?

Feather Evolution Proved?
January 21, 2009
Another claim of feather evolution was reported in PNAS.1  Creationists have long claimed that the evolution of feathers from reptilian scales is an intractable problem for Darwinists (example: 1994 article from Creation magazine).  Does the paper provide incontrovertible proof that feathers had evolved in dinosaurs before birds took flight in the air?     Beipiaosaurus, […]
