Chimpanzee Genome Published: Is There a Monkey in Your Genes?
September 1, 2005
Nature’s cover story September 1 is about the publication of the chimpanzee genome.  Evolutionists are digging through the data for evidence of human common ancestry.  Have they found it?  The results, as usual, are mixed: MSNBC News states the situation concisely: “Genome comparison reveals many similarities – and crucial differences.”  Here is the gist of […]

What Do You Get When You Cross a Lion with a Tiger?
August 10, 2005
A liger, that’s what.  No kidding: you get a big cat with a mane and faint stripes that likes to play in the water.  National Geographic News has a special article, with photos, about ligers. This is offered without much comment, just for those who want to learn about something unusual in the animal kingdom, […]

What Is Really Known About the Genetic Basis of Evolution?
July 25, 2005
Now that the genomes of a variety of plants and animals have been published, is there a clear picture of evolution emerging?  Sean Carroll (Howard Hughes Medical Institute) wrote a review in PLoS Biology,1 in which he explored the current thinking about the evolution of anatomy at the genetic level.  The thing to watch for […]

More Evidence the Molecular Clock is Broken
July 15, 2005
“We live in interesting times,” grinned David Penny in Nature,1 reporting on how estimates of evolutionary past based on comparative genomics (the molecular clock) is producing confusing results.  Apparently, evolutionary geneticists are going to have to make use of the theory of relativity – i.e., that how fast the clock ticks depends on the viewpoint […]

The Death of the Concept of “Junk DNA”
July 15, 2005
“God don’t make no junk” has been a slogan for the self-esteem movement, and now no less than Science Now is providing support at the genetic level.  “Don’t call it junk” the article announces, indicating that stretches of non-coding DNA are apparently not useless regions of material as previously believed, but vital to the regulation […]

Cell Wonders Accelerate
June 14, 2005
Scientific papers on cell biology continue to uncover amazing things as techniques improve to peer into the workings of these units of life.  Here are our Top Ten from the last few weeks: Immunity Tunes:  A press release from Johns Hopkins talked about how, unlike other cells, immune cells undergo a “dizzying loop of activity” […]

Descendants Can Overcome Parental Mutations
March 28, 2005
Bad genes from both parents may not spell doom in all cases.  Scientists at Purdue University found that if two parents have bad mutations, the child can sometimes reconstruct the correct gene from the grandparents.  “Our genetic training tells us that’s just not possible,” said Bob Pruitt, co-researcher on the team that ran the experiment […]

Astrobiology: Follow the Money
January 7, 2005
To date, astrobiology remains, as George Gaylord Simpson once quipped, “an area of study without a known subject.” Yet it is one of the hottest research areas within NASA. A renowned origin-of-life researcher from Scripps Institution of Oceanography, Dr. Jeffrey Bada, found out why when he read the new book The Living Universe: NASA and […]

Darwin’s Finches: Researchers Tweak the Beak
September 3, 2004
Every once in awhile, a new angle on Darwin’s finches (an icon of evolution) appears in print. Peter and Rosemary Grant, who have devoted their life to studying everything possible about these related species of birds that inhabit the Galápagos Islands – only to find that evolutionary changes are reversible (see 04/26/2002 headline) – have […]

Eugenics Documentary Opens at Holocaust Museum
April 22, 2004
Michael Ollove at the Baltimore Sun reports on a new exhibit at the U.S. Holocaust Museum entitled Deadly Medicine: Creating the Master Race.  The exhibit shows a 1937 Nazi propaganda film that invokes the law of natural selection as support for weeding out the unfit.  Ollove writes, The narrator declares that “we humans have sinned […]

Evolution As Assumption
December 20, 2002
51; Reasoning requires premises: axioms or truths taken for granted.  Notice the premise of reasoning stated in a recent article on Science Daily: “Because all living organisms inherit their genomes from ancestral genomes, computational biologists at MIT reasoned that they could use modern-day genomes to reconstruct the evolution of ancient microbes.”  They used an evolutionary […]

Human-Ape Gap Quadruples
December 20, 2002
Remember that old truism that humans and chimpanzees share 98.5% of their genes?  Try 94% instead.  That’s a new estimate by Matthew Hahn (Indiana U) and a team who published in a new online journal, PLoS One.1  J.R. Minkel, writing for Scientific American, said “The 6 percent difference is considerably larger than the commonly cited […]
