Answering DiEb: Just what is “search” in a sense relevant to ID?

For some time now, objector DiEb has been raising the question, what do we mean by speaking of “search” in the context of evolutionary search. At 311 in the parody thread, she [IIRC] remarks: >>Search is a central term in the work of Dr. Dr. William Dembski jr, Dr. Winston Ewert, and Dr. Robert Marks Read More…

Recent paper: A serious consideration of pathway complexity in life forms

Abstract: (public access)One thing that discriminates living things from inanimate matter is their ability to generate similarly complex or non-random structures in a large abundance. From DNA sequences to folded protein structures, living cells, microbial communities and multicellular structures, the material configurations in biology can easily be distinguished from nonliving material assemblies. Many complex artefacts, from Read More…

Another axe lying at the root of the Tree of Life

A brand new early eukaryote (“its own eukaryotic lineage”) From Katarina Zimmer at The Scientist: From an aquarium at the Scripps Institution of Oceanography in San Diego, California, scientists have identified a unicellular species that could shed light on how eukaryotes evolved, they report in Current Biology this week (November 22). The tiny organism—named Ancoracysta Read More…

Evolution as a Ralph’s Supermarket Store

Over at the The Skeptical Zone there’s a reference to a post from Larry Moran’s blogsite. The question of irreducible complexity is revisited, and, torn to shreds in the eyes of evolutionary thinkers. For them it seems sufficient to simply announce the “presence” of some needed ingredient of the putative IC system of proteins in Read More…

Flagellum gives bacteria a sense of touch. Behe is right.

Irreducible complexity. From ScienceDaily: Although bacteria have no sensory organs in the classical sense, they are still masters in perceiving their environment. … Swimming Caulobacter bacteria have a rotating motor in their cell envelope with a long protrusion, the flagellum. The rotation of the flagellum enables the bacteria to move in liquids. Much to the Read More…

What is the term “surprisingly complex” doing in science PRs about life forms these days?

From ScienceDaily: Cell signals that trigger wound healing are surprisingly complex The researchers were testing two prevailing hypotheses for the wound-response trigger. One is that damaged and dying cells release proteins into the extracellular fluid which surrounding cells sense, causing them to boost their internal calcium levels. This increased calcium concentration, in turn, triggers their Read More…

New paper: A Complex Lens for a Complex Eye

Abstract: A key innovation for high resolution eyes is a sophisticated lens that precisely focuses light onto photoreceptors. The eyes of holometabolous larvae range from very simple eyes that merely detect light to eyes that are capable of high spatial resolution. Particularly interesting are the bifocal lenses of Thermonectus marmoratus larvae, which differentially focus light Read More…

How can we measure specified complexity?

A friend asked about this common intelligent design concept. Specified complexity, also called complex specified information (CSI): Life shows evidence of complex, aperiodic, and specified information in its key functional macromolecules, and the only other example we know of such function-specifying complex information are artifacts designed by intelligent agents. A chance origin of life would exceed Read More…

Design Disquisitions: Peter S. Williams on Intelligent Design

In the latest post at Design Disquisitions I focus on the excellent work on ID by British philosopher Peter S. Williams. He has published several papers, and has many high quality articles and media presentations on the subject. His work was instrumental in initiating my change of mind from theistic neo-Darwinism to design. Highly recommended stuff! Peter Read More…

From ScienceDaily: How nature engineered the original rotary motor The bacterial flagellum is one of nature’s smallest motors, rotating at up to 60,000 revolutions per minute. To function properly and propel the bacterium, the flagellum requires all of its components to fit together to exacting measurements. In a study published in Science, University of Utah Read More…
