Fly Swiftly

The common swift is being eyed by aircraft engineers who want to go fast, high, and green.  Science Daily says these engineers are “inspired by nature.”     Calling Apus apus a common “swift” is like calling an orange an orange.  They are swift!  These incredible birds dart about effortlessly and spend their lives almost […]

Polishing Darwin’s Icons

Finch beaks, peppered moths, transitional forms – the standard props for evolution have been scrutinized ad infinitum for decades.  Can anything new be said about them?  Find out in these recent articles. Peppered moths:  The peppered-moth story just about collapsed when investigators realized that the famous pictures that adorn textbooks were staged, because the moths […]

Lizard Hair and Other Fables

In some science reports, it’s hard to tell where the data stops and the speculation begins.  In any case, evolutionary theory usually arrives in time to take credit for whatever happened in the unobservable past (cf. 08/24/2007). Bad hair joke:  Live Science wants you to blame your bad hair days on lizards.  Why?  Because according […]

Another Strange Chinese Fossil Found: Dinosaur or Bird?

Feathers and wings are among the most distinguishing characteristics of birds.  “Integumenary features” have been found on some dinosaur fossils, and true feathers have been found on some strange-looking extinct birds.  The news media often try to marry the two into a committed relationship using exaggerated artwork.  They have been found imagining feathers on fossils […]

Birds Need Beaver

Things go better with Beav around.  Science Daily has a delightful entry about the ecological benefits that beaver ponds provide for migratory birds.  It says that beaver are not just beneficial for our feathered friends; they are vital.  Because of the rich streamside habitat that grows around beaver ponds, the formula is simple: the more […]

Did This Dino Have Bird Breath?

Birds are the only vertebrates with a unique one-way, flow-through breathing system that includes hollow bones.  Their unique respiratory system is part of the set of features that allows flying with its need for rapid metabolism.  Science news outlets are clucking wildly about another putative missing link between dinosaurs and birds: “Meat-eating dinosaur from Argentina […]

Animals Got Rhythm; Scientists Don’t

Here’s a biological puzzle with plenty of room for young researchers to solve: the workings of biological rhythms.  All animals respond to rhythms in periods of hours, days, weeks, months, and years, but as George E. Bentley (UC Berkeley) wrote in Current Biology,1 how they do it is only partially understood.  “Sometimes the questions are […]

Flightlessness Evolved Four Times

An article on Science Daily claims that the famous flightless birds – African ostriches, Australian cassowaries and emus, New Zealand kiwis and South American rheas – are unrelated.  There was no flightless common ancestor.  They lost their ability to fly independently, scientists say, because of “parallel evolution.”     This would also mean that emus […]

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 […]

Feather Fossil Fallacy?

Imprints of melanocytes have been found in fossil feathers.  What does this mean?  The popular science news reports, like Science Daily, Live Science, PhysOrg and the BBC News seem convinced it can tell us something about how birds evolved from dinosaurs.  Understanding what was discovered requires sifting through claims that go far beyond the evidence. […]

Birds of Different Feathers Evolve Together

Are pigeons like parrots?  Are hummingbirds like hawks?  And are falcons unlike eagles?  Scientists are all a-flutter after results of a massive genetic comparison of birds has put some members in unlikely pigeonholes.  “The largest ever study of bird genetics has not only shaken up but completely redrawn the avian evolutionary tree,” said Science Daily.  […]

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 […]

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 […]

Itemized Deductions

Here are some free deductions to take the edge off Income Tax Day…. as long as one deduces correctly. Israel is picking a national bird.  So what feathered friend will represent the Holy Land?  “The nine finalists include the hoopoe, the owl, the spur-winged plover, and the griffin vulture, but no doves.”  Source: Science, Random […]

Peacocks Don’t Dress for Success

The male peacock’s fancy feather show: an icon of Darwin’s theory of sexual selection, right?  Then why did Japanese scientists tell Discovery News that the females pay them little attention?     The article claims that the male’s appearance fails to interest, much less excite, the females, who seem to pay more attention to his […]
