Researcher: “We’ve made incremental progress in understanding this fascinating machine,” says Liu. “We hope to continue to work on this for decades to solve how the flagella of different bacteria uniquely evolved. We’ve just touched the tip of the iceberg of understanding this beautiful structure.”
Schulz: This third paper (Part 3) concludes the three-part study with original observations. The observations include an ontology of the exceedingly specific protein binding relationships in the flagellum. … Finally, it is suggested that a motility organelle of this scope and scale seems profoundly unlikely to naturally evolve in the absence of foresight and mindful intent.
Pultz: Empirical evidence (from the world of engineering) supports the assumption that complex functional systems like motors do not arise via random changes to already existing systems. Empirical evidence, even from biology itself, also supports the common knowledge that random changes to functional systems disturb, disrupt, or destroy function.
The flagellum is a good example of what doesn’t work in purely naturalist explanations. None of it happened by chance unless you think masses of information can just suddenly pop into existence by chance. Wouldn’t that be magic? Miracle?
Question: If the last common ancestor of the bacterium had a flagellum, what do we really know about the evolution of the flagellum? Isn’t that a bit like finding a stone laptop in a Neanderthal cave? That said, it’s nice to see horizontal gene transfer getting proper recognition.
Darwinism’s key strength is that it is much simpler and more straightforward than life forms are.
As more of this type of information becomes available, expect the topic of irreducible complexity to be no longer discussable. When it can’t be debunked, it can be ruled undiscussable.
Now at last, courtesy a science preprint, we have a name that makes sense to us. The “irreducible complexity community” — the ICs.
Our universe seems fine-tuned for life to come into existence, as Michael Denton stresses. If so, life may indeed inhabit other planets. If people believe that there is intelligent life on other planets in the galaxy, the best theory to support it, absent evidence at present, is intelligent design.
Researchers: “To build the machinery that enables bacteria to swim, over 50 proteins have to be assembled according to a logic and well-defined order to form the flagellum, the cellular equivalent of an offshore engine of a boat.” They ADMIT this? It sounds like a Recovery Meeting.
In October 2006, Nick Matzke, a name not unfamiliar to denizens of UD, and Mark Pallen co-authored a review article for Nature Review of Microbiology regarding the status of research into the evolutionary origins of the bacterial flagellum. Matzke and Pallen felt the need to write such an article because since the publication of Michael Read More…
Here’s an example of what Michael Behe is (actually) talking about in Darwin Devolves The evolution strategy “Break or blunt any functional coded element whose loss would yield a net fitness gain”: Eleven authors writing in PLOS Biology found that “γ-proteobacteria eject their polar flagella under nutrient depletion, retaining flagellar motor relic structures.” When there’s Read More…
The world of Darwinian evolution features so many exceptionally clever animals that are nothing like the humdrum creatures we must tie down or tranquilize in order to help. And the profs just attribute it all to natural selection, as if that would explain anything in a situation where some prevision seems required.
This week’s post at Design Disquisitions is the first in a series of articles entitled ‘Critic’s Corner’ where I focus on a critic of ID. The main purpose of these posts is to document their work relevant to ID and also to document the direct responses to the particular critic in question, by those sympathetic to Read More…
