An article in PLoS Biology makes an astounding claim which is not consistent with an non-thinking random process. No, they are not saying it’s creationism, which would give the likes of Dawkins who is an militant atheist a heart attack, but in fact what they are claiming is that evolutionary processes are bias.
“Genes that have experienced accelerated evolutionary rates on the human lineage during recent evolution are candidates for involvement in human-specific adaptations.
To determine the forces that cause increased evolutionary rates in certain genes, we analyzed alignments of 10,238 human genes to their orthologues in chimpanzee and macaque. Using a likelihood ratio test, we identified protein-coding sequences with an accelerated rate of base substitutions along the human lineage.”
“These genes also show evidence of clusters of weak-to-strong biased substitutions. These findings indicate that a recombination-associated process, such as biased gene conversion (BGC), is driving fixation of GC alleles in the human genome. This process can lead to accelerated evolution in coding sequences and excess amino acid replacement substitutions, thereby generating significant results for tests of positive selection.”
Does this mean evolution is not random anymore but now “biased?” We are talking about a process with no intelligence. We are talking about a process that merely uses random accidents.
“Regions of the human genome that appear to evolve rapidly may have been under strong positive selection and could contain the genetic changes responsible for the uniqueness of our species.”
Austin L. Hughes, an evolutionary biologist at the University of South Carolina has stated there is no “signature on the genome” and he is right about this aspect of evolution but wrong in other ways. Not one is detectable for positive selection, so this makes it mere speculation and so are all the thousands of scientific papers including this latest article in PLoS.
Evolution is full of gaps, often times these gaps are filled with more assumptions, and more speculations, not to mention more gaps. It’s not explanatory power as some would like to suggest, but just explanations that contains a lot of jargon at times. It’s what I call a maze trying to avoid an intelligent designer, namely God, as seen it’s claiming evolution is baised now. All this hypothesis does and it does it very well, is create dead ends.
