Paleofantasy: Brain Evolution Is Mere Storytelling

When it comes to explaining the brain, evolutionists are completely in the dark.  That was the surprising message in a presentation to the annual meeting of the American Association for the Advancement of Science by Harvard evolutionist Richard Lewontin.  James Randerson blogged the presentation in the UK Guardian, beginning, “We know nothing about brain evolution.  […]

Fast Protein Fine-Tunes the Ear

Remember prestin?  It’s a motor protein in the inner ear, discovered in 2001 (03/27/2001), that acts so fast – within millionths of a second – its discoverers named it after the word “presto!” (02/21/2002).  Scientists have been studying its role as a volume adjuster (07/31/2007) that allows it to amplify sound 10,000-fold (09/19/2002) .  New […]

Getting a Hand on Facts and Meanings

What could be more simple than pressing a button with your finger?  That “seemingly trivial action is the result of a complex neuro-motor-mechanical process orchestrated with precision timing by the brain, nervous system and muscles of the hand.”  So says a press release from University of Southern California posted on EurekAlert.     Simple, everyday […]

Humans Excel at… Please Wait… Patience

Here’s another thing that distinguishes humans from animals: patience.  Current Biology usually has a “Quick Guide” feature on some aspect of biology.  In the latest issue, patience was the patient.  First of all, what is it? Humans and other animals often make decisions that trade off present and future benefits.  Should a monkey eat an […]

The Evolutionary Inference

Today’s Darwinian Just-So Story comes from a paper in PNAS.1  Three Italian scientists did experiments on the perception of two-day old human infants.  They found that the babies tended to pay more attention to biological motion than non-biological motion, and looked longer at right-side-up displays than upside-down ones.  Their conclusion: “These data support the hypothesis […]

Your Body Says: Resolve to Exercise

Even moderate exercise can prevent health risks, an article in Science Daily says.  Want to keep the waist trim?  Reduce the bad cholesterol and triglycerides, and increase your HDLs?  Want to lower your risk of diabetes, heart attack and stroke?  Then get out and walk.  You don’t have to become a jogger or gym addict.  […]

What Keeps Skin Strong? Velcro!

Skin would fall to pieces were it not for velcro-like molecules that bind its cells together.  These molecules, called cadherins, make skin strong but also supple.  Their secret was explained by Ashraf Al-Amoudi of the European Molecular Biology Laboratory, quoted in Live Science.  “The trick is that each cadherin binds twice: once to a molecule […]

Dealing with Light at the Extremes

“Light is the most important variable in our environment,” wrote Edith Widder, a marine biologist.  The inhabitants of two different ecosystems have to deal with either too little or too much.  Let your light so shine:  A thousand meters below the sea surface, all sunlight is extinguished.  Yet for thousands of meters more, creatures live […]

The Brain Evolved!… Didn’t It?

Evolutionary neurologists are so absolutely sure the human brain is a product of evolution from lower primates over millions of years, they are able to talk openly and frankly about problems with the particulars.  But in reading some of their own reviews of current ideas, it is not clear which has been evolving: the brain […]

Developing Ear May Have Tuning Fork

What tunes up an embryo’s ears before it hears its first sound?  A new study suggests that support cells in the cochlea, long thought to be inert, have a role in tuning up the hair cells during development.  Experiments by Dr. Dwight Bergles and a team at Johns Hopkins suggest that cells in a tissue […]

Month-End Close-Out

Sometimes the creation-evolution news comes in too fast.  Here’s a baker’s dozen from the October shelf, lest they go stale; time to start a new batch for November. Charity begins at worldview:  David Cyranoski in Nature (450, 24-25, 10/31/2007) investigated why the level of charitable giving in prosperous Japan is a tenth of that in […]

Inner Ear More Complex than Thought

Another level of complexity has been added to the mystery of hearing.  Scientists at Massachusetts Institute of Technology (MIT) found that another membrane in the cochlea of the inner ear, once thought to be passive, is actively involved in transmitting sound waves to the hair cell receptors.  Their work was published in PNAS.1     […]

Appendix to the Vestigial Organs Story: Whoops, Function Found

The appendix is not just a useless organ left over from our evolutionary past, new research is showing.  According to an Associate Press article (see MSNBC News), this “seemingly useless organ may produce, protect good germs for your gut.”  Scientists at Duke University Medical School believe that the appendix can regenerate the normal bacterial flora […]

Don’t Just Sit There; Evolve

Have you ever wondered why your body doesn’t evolve?  After all, it is kind of like a population of trillions of organisms.  Why shouldn’t it follow the rules of natural selection?  Philip Ball asked this question in News@Nature recently.  “Evolution is usually thought of as something that happens to whole organisms,” he teased.  “But there’s […]

Are You a Glorified Ape?

Evolutionists seem in a bit of a quandary lately.  They are convinced that humans evolved from apes, but cannot deny the large cognitive gaps between humans and the alleged nearest ancestors, the great apes.  It’s not just a matter of IQ.  The social skills, language, reasoning, altruism and empathy humans express have no parallels in […]
