New Research Continues to Point to a Super Progenitor

Everyone knows biology is full of complicated designs, but evolutionists think it arose spontaneously, as a result of the play of natural laws. In other words, it happened to happen. First there was nothing, then there was something, then that something became very complicated. All this just happened to happen.  Read more

The Book is not the Ink and Hardware is not the Software

  In this post the UD news desk quotes OOL researcher Jack Szostak:  “We think that a primitive cell has to have two parts. First, it has to have a cell membrane that can be a boundary between itself and the rest of the earth. And then there has to be some genetic material, which has to perform some function that’s useful for the cell and get replicated to be inherited.”   He believes they have the “membrane” part figured out, which leads him to suggest that they are about “halfway” to figuring it all out. Really?  Consider a computer in a paper sack.  If I figure out how to make a paper sack does that mean I am “halfway” toward Read More ›

Human genes use a dual strategy of “prevention and cure” to deal with a type of error

From “Preventing Dangerous Nonsense in Human Gene Expression” (ScienceDaily, Oct. 14, 2011), we learn: Human genes are preferentially encoded by codons that are less likely to be mistranscribed (or “misread”) into a STOP codon. This finding by Brian Cusack and colleagues from the Max Planck Institute for Molecular Genetics in Berlin and the CNRS in Lyon and Paris is published in the open-access journal PLoS Genetics. In biological systems, mistakes are made because the cellular machinery is complex and error prone. The errors made in copying DNA for transmission to offspring (genetic mutations) have so far been the primary focus of molecular evolution. But errors are much more frequent in the day-to-day task of gene expression, for example in the Read More ›

Two-Fold Fragile Codons and Amino Acids

If you read Brian Cusack’s paper (discussed here) you may have wondered why the evolutionists did not distinguish the two-fold fragile codons from the single-fold fragile codons. Perhaps I missed it, but I saw no mention of this distinction. The evolutionists define as “fragile” those codons that can be changed into a STOP codon with a single substitution. They are shaded gray in the table below (from Figure 1 in the paper):  Read more
