Uncommon Descent Serving The Intelligent Design Community


Nachman’s Paradox Defeats Darwinism and Dawkins’ Weasel

The following is a crude 1-minute silent animation that I and members of the IDCS Network put together. God willing, there will be major improvements to the animation (including audio), but this is a start. Be sure to watch it in full screen mode to see the details.


The animation asserts that if harmful mutation rates are high enough, then there exists no form or mechanism of selection which can arrest genetic deterioration. Even if the harmful mutations do not reach population fixation, they can still damage the collective genome.

The animation starts off with healthy gingerbread men as parents. Each spawns ginger kids, and the red dots on the kids represent them having a mutation. The missing ginger limbs are suggestive of severe mutations, the more mild mutations are represented by ginger kids merely having a red dot and not severe phenotypic effects of their mutation. The exploding ginger kids represent Selection doing its thing and removing the less functionally fit from the population. The persistence of red dots on the ginger kids represents persistence of bad mutations despite any possible mechanism of selection.

Nobel Prize winner HJ Muller (of Muller’s ratchet fame) suggested that the human race can’t even cope with a harmful rate of 0.1 per new born. The actual rate has been speculated to be on the order of 100-300.

The animation uses a conservative harmful rate of 1 and argues (with some attempts at humor) that deterioration would thus be inevitable even with a harmful rate of 1 per new born.

I save discussion in the comment section the relevant but technical topics of truncation selection, sexual reproduction, recombination, synergistic epistasis, compensatory mutations, relief from Muller’s ratchet etc. These highly technical topics should be addressed and were not included in the animation. We can discuss them in the comment section.

However, the essential problem of mutation rates and deterioration is depicted by the animation. How this cartoon is illustrative of reality (when we consider the technicalities such as recombination, sexual reproduction, synergistic epistasis), can be discussed in the comment section.

Cambrian Explosion Caught on Film

New Cellular Animation: Journey Inside the Cell

Dr. Stephen Meyer, author of Signature in the Cell: DNA and the Evidence for Intelligent Design, narrates a new video illustrating evidence for intelligent design within the cell.  This excellent new video illustrates aspects of the role of information in the cell including protein synthesis. From Evolution News and Views: “This video is going to make things worse for critics of intelligent design,” Dr. Meyer explains. “They will have more difficulty convincing the public that their eyes are deceiving them when the evidence for design literally unfolds before them in this animation.” Narrated by Meyer, the video is a short tour of the molecular labyrinth, the cell’s sophisticated information-processing system, which not only produces machines, but also reproduces itself.
