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 […]

How Floppy Feet Produced Marathoners
November 26, 2008
A picture of a muscle-bound furry gibbon adorns a story on Science Daily that claims, “Floppy-footed Gibbons Help Us Understand How Early Humans May Have Walked.”  The story describes how two European researchers photographed the footwork of wild gibbons to find connections to human evolution.  It turned out that gibbon footfalls are very different from […]

Far-Out Science
November 25, 2008
The following list of bizarre stories coming from science news outlets is jarring on two fronts: it shows how little scientists understand, and calls into question what counts as science these days.  Some stories illustrate one or the other; some both. Roar of the aurora aura:  Both Saturn and Mars turned up auroras that are […]

Lizard Hair and Other Fables
November 12, 2008
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 […]

Snails Walk on Water
October 27, 2008
Why is that scientist staring at a snail?  He’s watching a miracle: walking on water.  This is not our exaggeration: Matt Kaplan on National Geographic News entitled his article, “How Snails Walk on Water Is a Small Miracle.”  If we can figure out the trick, we might be able to make little robots do it […]

Another Strange Chinese Fossil Found: Dinosaur or Bird?
October 22, 2008
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 […]

Tooth Evolution Theory Lacks Bite
October 14, 2008
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 […]

Deep Life Is Right at Home in Total Darkness
October 10, 2008
It seems every year scientists find organisms thriving in environments thought too inhospitable for life.  A new word was coined for these organisms: extremophiles – lovers of the extreme.  Two recent discoveries push the envelope of extreme environments almost to the deep limit. Pressurized fish:  The bottoms of the deep ocean trenches of the Pacific […]

A Turtle Missing Link: Are We Missing Something?
October 9, 2008
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 […]

Living Better Bioelectrically
October 4, 2008
Electric eels are inspiring a new generation of fuel cells.  Science Daily reported that a remarkable fusion of engineering and biology may lead to tiny electronic devices that run on biology’s own energy currency, ATP.  “Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers at […]

How the Evolution Story Became Like Jellyfish
September 30, 2008
“How the [blank] got its [blank]” is the template for story titles imitating Rudyard Kipling’s Just-So Stories: i.e., How the Camel Got His Hump and How the Leopard Got His Spots.  Kipling wrote these as silly stories to entertain children, not to be taken seriously by scientists.  Knowing that creationists often criticize Darwinian explanations as […]
