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, […]

Biology Now Includes Fluid Dynamic Construction
January 13, 2009
There’s an old legend that Tibetan monks built a wall by levitating heavy stones with sound by beating their drums and gongs.  Something not quite so fantastic but still amazing is done by cells in the embryo.  Scientists have filmed zebrafish embryos using beating cilia to build little stone structures that they use for balance.

Watch for Flying Giraffes (and Convergent Evolutionists)
January 9, 2009
Imagine giraffe-sized animals that could fly.  They lived.  National Geographic News has an illustration of an extinct pterosaur, tall as a giraffe, that was able to leap into the air and flap its wings for sustained powered flight.     Live Science discussed work by Michael Habib [Johns Hopkins U School of Medicine] on the […]

Nature Struts Darwin Gems
January 2, 2009
Like a showcase of pearl-handled revolvers, an armory of evidences Nature calls “Darwin’s Gems” have been exhibited to warn creationists that Darwin Day will be defended next month with a show of force.  The authors, Henry Gee (former editor of Nature), Rory Howlett and Philip Campbell have made their 15 Evolutionary Gems freely available “and […]

Handy Motor Found in Virus
December 30, 2008
Your job today is to stuff a delicate chain into a barrel without breaking it and make it wrap neatly inside.  A tiny virus does this with helping hands, reported Purdue University.  A research team uncovered the mechanism of a “powerful molecular motor” that crams the viral DNA tightly into the capsid with the help […]

Bat Evolution: The Play’s the Thing
December 23, 2008
According to the Darwinian script, each animal evolved its particular adaptations from an ancestor lacking those adaptations.  Take bats.  They must have evolved their wings and sonar from mouse-like ancestors that lived on the ground.  Is it enough to imagine these things, or should we expect science to provide evidence that is what really happened?

Blame Hiccups on Your Inner Fish
December 16, 2008
    Why do humans get hernias and hiccups? Neil Shubin says it’s because of your inner fish. In the Scientific American series on Darwin, the discoverer of Tiktaalik was trying to show how evolutionary theory sheds light on human anatomy. He looked back to fish and amphibians and found insight. “A glimpse inside the […]

Evolutionary Mutualism Flutters
December 12, 2008
A story on Science Daily is decorated with a butterfly collection.  Amazonian butterflies studied by an international team were chosen to test Darwin’s theory of mutualism – a kind of symbiosis in which two species benefit one another.  The test yielded a surprise.     The idea going in was that sister species would evolve […]

Fish and Reptiles Converge on Magnetic Navigation
December 11, 2008
Two very different kinds of animal both have outstanding ability to navigate by earth’s magnetic field: salmon and sea turtles.  A new hypothesis by scientists at University of North Carolina at Chapel Hill, published in PNAS,1 suggests that the young are “imprinted” with their local magnetic field signature at birth. From a navigational perspective, some […]

Thanks to Clam Design, Stronger Materials Are Coming
December 6, 2008
Scientists at Lawrence Berkeley National Labs have produced a lightweight composite material 300 times stronger than its constituents.  How?  By taking inspiration from clams.     The team, writing in Science,1 described nacre, the shiny mother-of-pearl found inside clam shells.  Because of the way it sandwiches crystalline aragonite with layers of protein (07/26/2004), nacre resists […]

Go to the Ant, Thou Farmer
November 30, 2008
We humans boast too much.  Agribusiness?  Ants have it down to a science.  “One of the most important developments in human civilisation was the practice of sustainable agriculture,” stated Science Daily.  “But we were not the first – ants have been doing it for over 50 million years.  Just as farming helped humans become a […]

An Evolutionary Fly in the Turtle Soup
November 29, 2008
A new fossil turtle was found.  Is it a missing link?  That depends on whether you believe the popular press or the scientists.     National Geographic News and Science Daily both led off with the missing link angle, complete with an artist reconstruction of the fossil turtle found in China named Odontochelys.  “Since the […]
