Tooth Evolution Theory Lacks Bite

The hardest substance in your body is your teeth.  The varieties of teeth among vertebrates is astounding, from the tiny incisors in a mole to the bone-crushing scimitars on a T. rex.  Many fossils are known only from their teeth.  One would think teeth are the best-studied objects in evolutionary theory, but a recent paper […]

A Turtle Missing Link: Are We Missing Something?

Everyone knows the iconic drawing of the parade of human evolution (see 09/23/2008 commentary); now, its turtle counterpart is making the rounds.  An article on New Scientist shows the march of progress from lizard to turtle.  The title says, “Fossil reveals how the turtle got its shell.”  Something is missing from the article, though: a […]

Ant What it Used to Be

A new species of subterranean ant discovered in Brazil is so weird, biologists have classified it as the sole representative of a new subfamily.  The alien creature has been whimsically named Martialis heureka: “the ant from Mars.”  An article about it in Nature News said, “It adds a new branch to the ant family tree […]

Butterfly Wings Xeroxed

If you can’t build it, copy it.  Scientists have had a hard time reconstructing the photonic crystals that make butterfly wings shimmer with light (01/29/2003), so they made, in effect, a carbon copy.  PhysOrg described how scientists at Penn State made impressions of the regularly-spaced geometric shapes from a butterfly wing and transferred it to […]

Fully Gecko 40 Million Years Earlier?

Amber, or fossilized tree sap, usually contains remnants of insect parts.  One piece, mined in the jungles of Myanmar, contained the foot of a gecko – alleged to be 100 million years old.  That’s 40 million years older than the previously claimed oldest gecko fossil.  This critter may have skittered under the feet of dinosaurs.  […]

Plant Perfume Manipulates Pollinator Behavior

You’re a plant, stuck in the ground.  Around you are organisms with wings flitting freely about.  You need to get them to land on your flowers, but not linger too long.  How do you do it?  Attract them with sweet smells, but send them away with a bitter aftertaste.  That’s how the tobacco plant manipulates […]

Can Worms Outsmart Humans?

Worms may seem creepy to some people, but they possess some amazing abilities.  How many of you had to struggle through calculus class, for instance?  Worms know it by heart, reported Greg Soltis at Live Science.  Their brains instinctively apply the logic of calculus to input signals from sensory inputs.  A University of Oregon biologist […]

Animal Patterning Keeps Scientists Puzzle-Solving

Here’s a fascinating area of research for a budding young scientist: the development of animal patterns.  Look at the dazzling wing patterns on butterflies in an illustration on Science Daily or consider a zebra’s stripes.  How do such patterns emerge from a single fertilized egg?  “Although this has been studied for years,” said a researcher […]

Asian Bees Speak European

Asian honeybees and European honeybees went their separate ways millions of years ago, say evolutionists.  Why, then, were Asian bees able to readily learn the European language?  An international team watched this happen.  They ran some affirmative-action integration experiments on the two species, and reported their results today in PLoS One.1     “The honeybee […]

An Evaluation of Evolution as an Explanatory Device

It is very common for scientists to claim this or that phenomenon “evolved.”  How well do such statements qualify as scientific explanations?  How much scientific heavy lifting is done by merely stating that things are the way they are because they evolved that way?  The following recent examples can be considered representative of the evolutionary […]

Fossil Frog-amander Claimed to Be Missing Link

It looks like a frog with four equal legs and a tail; is it the ancestor of frogs and amphibians?  It depends on whether you read the original paper or the popular press.     Live Science writer Jeanna Brynner is absolutely certain this puts a feather in Darwin’s cap: “the creature represents a transitional […]

Animals Outsmart Scientists

In science, long-standing beliefs are often challenged by new evidence.  Several recent findings not only show animals to be more remarkable than thought, they pose some new questions for evolutionists. Slothlessness:  Sleeping almost all day, the sloth is the epitome of laziness in the animal kingdom.  Or is it?  The BBC News now tells us […]

Sweet Solutions from Nature

Human engineers continue to look at plants and animals for inspiration.  Biomimetics – the imitation of biology for design technology – shows no sign of running out of ideas. Sweet gas:  A spoonful of sugar in the gas tank?  Science Daily reported on progress in converting plant sugars into clean-burning hydrogen – using biological enzymes.  […]

Evolution Revealed?

When the news reports evidence for evolution in the fossils or genes, it sounds like Darwinism has been all but proved, because scientists have observed its effects.  Can these stories withstand deeper scrutiny? Lungless frog:  Science Daily reported a frog without lungs in Borneo.  Lunglessness in tetrapods has been reported in salamanders and other amphibians, […]

Moths Navigate in the Dark Against the Wind

A moth weighs little more than a piece of paper, but it does things no paper blowing in the wind can do: it can navigate with and against the wind to get where it needs to go.     Science Daily reported on work by UK scientists who used “entomological radar” to monitor where the […]
