Introducing the Stretch & Squish Theory of Evolution
December 14, 2004
How do you squish an arm into a wing, or stretch a fin into a leg? This sounds like the silly putty theory of evolution.

Did Life Begin as “Failed Mineralogy” on the Seafloor?
December 3, 2004
A geologist with a lot of bluff and bluster makes the origin of life sound easy, but gets nailed by direct questions.
Origin-of-Life Expert Jokes about Becoming a Creationist

Chemist admits problems in chemical evolution are so hard, he is tempted to become a creationist.
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 […]
Homology for Dummies
May 5, 2004
Current Biology likes to give its readers primers on various concepts. The topic in the May 4 issue is homology.1 Caleb Webber and Chris P. Ponting explain this important evolutionary term for the rest of us. The Q&A format also introduces homology’s siblings: analogy, orthology, paralogy, xenology, and synteny. Some readers may not realize that […]
Origin-of-Life Researcher Leslie Orgel Interviewed
May 5, 2004
The May 4 issue of Current Biology1 contains an interview with organic chemist Leslie Orgel of the Salk Institute, who in 1974 published the book The Origin of Life on Earth with Stanley Miller of spark-discharge fame (see 05/02/2003 and 10/31/2002 headlines). He considers his biggest mistake not thinking of the RNA World scenario first […]
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 […]
Can Evolution Create Homologous Structures by Different Paths?
April 22, 2004
Günter Thebien (Friedrich Schuller U, Jena, Germany) is baffled about how two plants arrived at similar structures by different evolutionary pathways. In the April 22 issue of Nature,1 he asks, Structures that occur in closely related organisms and that look the same are usually considered to be homologous – their similarity is taken to arise […]
Rethinking the Geological Layers
March 5, 2004
One of the most formative ideas in Darwin’s intellectual journey was the concept of gradualism, the principle of “small agencies and their cumulative effects.” This idea became a dominant motif in his philosophy of life. Describing how the assumption of gradualism permeated his last book (on earthworms) shortly before his death, Janet Browne, in her […]
Happy Darwin Day?
February 13, 2004
Humanists hope to have a new international holiday by 2009: Darwin Day. (Feb. 12 was Darwin’s birthday as well as Abe Lincoln’s, so it’s already set aside as a holiday in America, but promoters want this to be an international event.) According to Robert Evans’ story in Reuters, the British Humanist Association believes such a […]
Why Darwin Is Like Yoda, and Darwinism Like Marxism
February 4, 2004
Homage for the master is palpable in John Vandermeer’s review (Science, Jan. 23)1 of a thick new book entitled Niche Construction: The Neglected Process in Evolution by Odling-Smee, Laland and Feldman (Princeton, 2004). Vandermeer seems almost worshipful in his opening lines: The nascent germ of many novel ideas in biology can be traced directly or […]

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 […]
The Why and How of Leopard Spots
October 20, 2002
51; A leopard may not be able to change its spots (Jeremiah 13:23), but maybe evolution can – if evolutionists – or Rudyard Kipling – can tell us how or why. A headline in the BBC News promised to tell us “how the leopard got its spots,” while PhysOrg promised to reveal, “Why the leopard […]
