Evolutionary Inferences: Are They Incontrovertible?
February 23, 2010
No matter what is found in plants or animals, it finds its way into an evolutionary explanation eventually.  Are these explanations driven by the data, or forced into a belief system?  Are other explanations possible?  Some recent reports might inform these questions. Your inner plant:  Get in touch with your inner plant with a report […]

Is Your Bod Flawed by God?
February 14, 2010
Are your body’s imperfections reasons for you to reject intelligent design and embrace evolution?  Professor John Avise (UC Irvine) thinks so.  His new book Inside the Human Genome was given good press by PhysOrg: “Distinguished Professor of ecology & evolutionary biology at UC Irvine, Avise also makes the case that overwhelming scientific evidence of genomic […]

For His Birthday, Darwin Gets a Scrambled Arthropod Tree
February 12, 2010
If Darwin lost his tree last year (01/22/2009), it would seem any corrections or rearrangements would be academic.  Nevertheless, eight evolutionary biologists at Duke University tried rearranging one of the biggest branches on Darwin’s tree of common ancestry – the highly diverse group known as arthropods (animals with jointed appendages).  Arthropods comprise the largest number […]

More Surprises for Darwin
February 11, 2010
It’s not uncommon for theories to have to deal with anomalies, but Darwinism sure seems to get more than its share.  Here are some recent examples. Fossils lie:  Fossils preserve unmistakable clues about past life, right?  Not so fast.  Nature reported that “Non-random decay of chordate characters causes bias in fossil interpretation.”1  The way early […]

Building a Cell: Staggering Complexity
February 2, 2010
“The living cell is a self-organizing, self-replicating, environmentally responsive machine of staggering complexity.”  Thus began a special section on “Building a Cell” in Nature last week.1  The section with five papers explores what is known about gene regulation, cell organization and signalling.  It’s an opportunity, as well, to see what scientists think about what they […]

Woese Slays Darwin
January 28, 2010
The king is dead!  Long live the king!  Such were the oxymoronic cries of olden times when royal succession took place.  Has Charles Darwin been dethroned?  One would think so, after reading Mark Buchanan’s article, “Horizontal and vertical: the evolution of evolution” in New Scientist.  Buchanan sets the stage: Just suppose that Darwin’s ideas were […]

Convergence: Explanation or Rescue Device?
January 26, 2010
The news media are telling us that bats and dolphins both hit on the same genetic pathway to evolve echolocation – even though they are on vastly different evolutionary lineages and use echolocation differently (one in air, one in water).  Since it is inconceivable that a putative shrew-like common ancestor of these very different animals […]

Molecular Machines Use Moving Parts
January 19, 2010
Research papers into the processes of molecular machines continue to reveal moving parts: “fingers” that open and close, ratchets that lock into place, and feet that move along tracks.  Here are a few samples from the voluminous literature that continues to pour from biophysics labs. DNA Polymerase I:  Scientific papers tend to be reserved in […]

What Value Do Evolutionary Explanations Provide?
January 13, 2010
We want value for our science dollars.  We know artists are into self-expression, but scientists need to offer more than just artistic prose: they are supposed to be in the knowledge generation business.  So we expect to gain one of two things from their scientific explanations.  One, we would like to gain practical knowledge that […]

Evolutionists Caught in the Act – of Exaggerating
January 4, 2010
A headline on Science Daily and PhysOrg announced breathlessly, suggested that mistakes are a gold mine for creative Darwinian power: “Mutations are the raw material of evolution.”     The press release went on to glorify Darwin: “Charles Darwin already recognized that evolution depends on heritable differences between individuals: those who are better adapted to […]

DNA Repair Requires Teamwork
January 3, 2010
As if the genetic code itself was’t incredible enough, researchers have been finding systems that repair it.  There are numerous pathways the cell can embark on to fix DNA errors.  Two key players were recently described in more detail in the journal Science.1     A damaged genetic code is worse than a book with […]

Simplest Microbes More Complex than Thought
December 29, 2009
The smallest, simplest cells are prokaryotes.  These are the bacteria and archaea that lack a nucleus and are usually considered primitive.  Scientists are finding, though, that they know many of the same tricks as the more complex nucleus-bearing eukaryotes.     PhysOrg reported that a species of Mycoplasma, among the smallest independent-living bacteria, is more […]

“Messy” Genomes: Did They Evolve?
December 14, 2009
The genomes of most eukaryotes are riddled with introns – intragenic regions – that have to be cut out by sophisticated DNA-transcribing machinery so that the true gene sections (called exons) can be spliced together.  Introns can vary from 20 base pairs to over 500,000 – significantly impacting the energy required to duplicate the genome.  […]

How One Bright Young Scientist Challenged the Junk-DNA Paradigm
December 5, 2009
A young snowboarder turned to science and turned the consensus on its head.  PhysOrg, in “Turning trash to treasure,” told the story of John Rinn (Harvard Medical School), who challenged the paradigm of “junk DNA” and discovered a new class of functional molecules: lincRNAs (large intervening non-coding RNA).  He found important functional molecules “in a […]

Polar Bears and Grizzlies Hybridize
November 4, 2009
What do you get when you cross a polar bear with a grizzly bear?  It’s not a joke; look at the BBC News and see.  You get bears with mixed shades of fur and a blend of characteristics.  Live Science also commented on the BBC report.     Scientists have known that these species can […]
