How Snakes Lost Their Limbs

Penn State scientists have a story for how snakes, which presumably evolved from lizards, lost their legs.  They had to burrow through tight places.     Part of their story involved disproving that snakes evolved from sea-going reptiles, like mosasaurs, explains the press release from Penn State’s Eberly College of Science.  They compared genes from […]

Proof of Life in Martian Meteorite Alleged – Again

Some Aussies are trying to scoop the Mars prize, it seems from a headline in the down-under Daily Telegraph.  While two American rovers are busily sniffing about for evidence of water (as a prerequisite for life) on opposite sides of the surface of Mars, the Australians are saying, “No worries, mate,” they already found Martian […]

Georgia to Teach Evolution, but Avoid the E Word

It’s not “evolution,” it’s “biological changes over time,”  asserts Georgia Superintendent of Schools Kathy Cox.  But sometimes good intentions can make both sides of a dispute upset, reports MSNBC News.  Pro-evolutionists think the state is trying to water down the teaching of evolution, and anti-evolutionists think changing the word does not change the meaning.  Cox […]

For Complex Life, Just Add Oxygen

When you take in a breath of fresh air, you let in a lively but dangerous molecule that would kill you if it were not that your cells have elaborate controls to utilize its energy for good and avoid its damaging potential.  Oxygen makes forests burn to ashes but also powers your muscles.  Astrobiologists realize […]

The New Phrenology Ostracizes Neanderthals

Scientists contrasted different points on Neanderthal skulls to modern human skulls, and concluded Neanderthals were a separate species.  The New York Times report by John Noble Wilford says that not all scientists are convinced, however, by the analysis published by Katerina Harvati et al. in the Proceedings of the National Academy of Sciences1 Jan. 26 […]

Does Microevolution Add Up?

Do numerous small changes add up to big ones, like Darwin thought?  In the Jan. 15 issue of Nature,1 New Zealand kiwi David Penny (Allan Wilson Center for Molecular Ecology and Evolution, Massey University) is hopeful that the new chimp genome will prove it so: The fundamental issue here is Darwin’s bold claim that “numerous, […]

Your Bacteria Ancestors

Dr. Peter Antonelli thinks he has mathematically proven that all multicellular organisms, including plants and animals and human beings, came from two ancient bacteria that met and formed a stable, consistent relationship.  His boast is explained on a University of Alberta press release.  He thinks most biologists don’t comprehend his mathematical models yet, but EurekAlert […]

Did Borax Evolve Into 20-Mule Teams?

You’re dating yourself if you remember the old TV western Death Valley Days, and its commercials about 20-Mule Team Borax.  (Mule teams actually did pull loads of borax from Death Valley to Mojave, quite a feat in those days, but that’s another story.)  In modern times, though, borax has made science news as a possible […]

How Do Plants Know When to Bloom?

Scientists like to use big words to impress the rest of us, so they have a term for how a plant decides when to bloom: vernalization.  But making up a word for a phenomenon is not the same as explaining it.     Everybody observes that plants seem to just “know” that spring is here, […]

Your Accelerated Eyes

When a beam of light hits your eye, a chain of events is set off that is really quite amazing.  Kendall J. Blumer (Washington University School of Medicine) describes a little of it in the Jan. 1 issue of Nature.1  You don’t have to understand the following description; just be glad you don’t have to […]

Line Between Neanderthals and Modern Humans Blurs

There seems to have been an intergradation between big-boned Neanderthals and modern humans, according to the BBC News.  “Newly identified remains from Vindija in Croatia, which date to between 42,000 and 28,000 years ago, are more delicate than ‘classic’ Neanderthals,” writes Paul Rincon.  Not only that, stone tools found nearby look like those of modern […]

Life Runs on Waterwheels

The cells of every living thing are filled with molecular machines, and one of the most fascinating is a rotary motor called ATP synthase (see April 2002 back issue, opening paragraph).  This is a true mechanical/electrical motor, found in every living thing from bacteria to elephants and palm trees.  It is really two motors in […]

How Darwinism Produces Job Security

One thing Darwinism has going for it: it provides endless opportunities to research stories that are nearly impossible to prove.     A case in point was provided in the Dec. 18 issue of Nature.1  John R. Hutchinson (Royal Veterinary College, UK), in a News and Views article on bird evolution, reviewed the new angle […]

Tired of Old Gaia?  Try This: New Gaia

James Lovelock gets the stage without flying fruit (yet) in the December 18 issue of Nature.1  His 1970-ish “living earth” view of evolution, the Gaia hypothesis, in which life and the earth co-evolve together as one big living system, gets a new screening as what might be called neo-Gaia in an unrefuted Concepts piece in […]

Photosynthesis Began a Billion Years Earlier Than Thought

According to the BBC News, some scientists have pushed back the evolution of photosynthesis a billion years earlier than previously believed, to 3.9 billion years ago.  This is based on uranium-thorium ratios of rocks in Greenland that led Danish researchers to conclude that they were deposited under oxidizing conditions.  Others are not sure the data […]
