Applying the Scientific Method to Prehistory
December 10, 2008
What could be more scientific than the scientific method?  A scientist observes an unexplained phenomenon.  He or she gathers data, analyzes it, proposes a hypothesis to explain it, and tests it.  The results are published in a peer-reviewed journal.  Mission accomplished, right?  Here are two papers on very different phenomena – one dealing with the […]

Unique “Orphan Genes” Are Widespread; Have No Evolutionary Explanation
November 19, 2008
We often hear about the similarities between genomes, but what about the differences?  There’s a growing realization that groups of animals have genetic orphans – genes that are unique to that line (see 01/02/2003).  These genes have no evolutionary homology or kinship to genes from other lineages.  How did they arise?  And what do they […]

Biological Complexity Continues to Astound
November 3, 2008
There’s more going on in your thinking apparatus than you think.  New scientific discoveries continue to unfold new layers of complexity and control.  Here are a few examples: Meta-code:  Your body has codes directing codes.  Geneticists were initially dismayed to find only 20,000 to 30,000 genes in the human genome.  “We were expecting that something […]

Plants Have Thermostats
October 13, 2008
Plants, being stuck in the ground, have few options when it gets hot.  They may not be able to move into the shade like animals, but they know how to cope.  They have a built-in thermostat that acts like a fire prevention department.  Science Daily tells the story.     Researchers at Michigan State identified […]

It’s Fun Seeing Evolution Falsified
October 8, 2008
“Mysterious Snippets Of DNA Withstand Eons Of Evolution” is the strange title of an article on Science Daily.  Gill Bejerano and Cory McLean from Stanford are wondering why large non-coding sections of DNA are very similar, or “ultraconserved,” from mice to man (see 08/18/2007).  Evolutionary theory would expect that non-functional genetic material would mutate more […]

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 […]

Leaves Don’t Fall; They’re Pushed
September 22, 2008
Rocks may fall (thus the need for warning signs on highways), but leaves are pushed off of trees by a genetic program.  The process, called abscission, has been mysterious for a long time.  A team from the University of Missouri has mapped out, for the first time, the abscission pathway in one plant.  Being this […]

Flightlessness Evolved Four Times
September 10, 2008
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 […]

How Not to Prove Positive Selection
September 5, 2008
Erase all that evidence for positive natural selection in the genes you’ve read about.  It’s all misleading confusion based on “certain poorly conceived statistical methods,” argues Austin L. Hughes, an evolutionary biologist at the University of South Carolina.  Writing a commentary in PNAS,1 he accused, “Thousands of papers are published every year claiming evidence of […]

How Chromosomes Pack Without Exploding
August 24, 2008
When preparing to divide, a cell has to copy all its DNA accurately and pack it into chromosomes.  A professor at U Chicago told Science Daily this is “like compacting your entire wardrobe into a shoebox.”  The cell has another difficulty in this compaction process, though: DNA, being negatively charged, resists packing.     Eukaryotes […]

Flatlife Has More Genes Than It Needs
August 23, 2008
The genome of a placozoan (“flat animal”) shows more complexity than one would expect for a simple life form.  According to evolutionists, it shows that even a barely-differentiated animal presumably ancestral to complex animals had the genetic toolkit of its more-advanced descendents.     Trichoplax adhaerens is a slimy-looking thing that sticks to aquarium walls.  […]

Admissions of Ignorance in Evolutionary Theory
August 11, 2008
For a scientific idea some have proclaimed as a fact no longer in need of proof, and as well-established as gravity, Darwin’s theory of evolution still reveals surprising weaknesses when its defenders speak about the details.  Detecting these weaknesses requires tuning out the media hype, and tuning into scientific papers and pro-evolution journals where evolutionary […]

Tree of Life in the Genes? Not Yet
July 23, 2008
Now that we have hundreds of animal genomes in the bank (the GenBank), is Darwin’s tree of life becoming visible?  If the image is present, it is extremely weak, said Michael J. Sanderson of the Department of Ecology and Evolutionary Biology at University of Arizona.  Writing for Science,1 he showed that only a small fraction […]

Mangrove as Metaphor
July 22, 2008
The mangrove – that shoreline tree with the salt-tolerant roots that grows into dense thickets – is the fulcrum of two unrelated news stories.  It never met a force it couldn’t handle.  It also provides metaphors for evolution and creation.     PhysOrg reported that the mangrove is a key to saving lives.  “The replanting […]

The Cro-Magnon Were Europeans
July 16, 2008
There’s no genetic difference between Cro-Magnon Man and modern Europeans, a genetic study reported by Science Daily.  Researchers took extra care to avoid contamination of bones found in southern Italy, they said.  They claimed Cro-Magnon people were able to maintain genealogical continuity for 28,000 years, remaining distinct from Neanderthals, whom they said lived in Europe […]
