One of the major discoveries in the study of DNA across species, as pointed out by Michael Behe is loss of information is what drives evolution. This is now being confirmed i9n recent studies. This implies that all the information for evolution was present at the beginning of life and with removal of some of it evolution advances, the exact opposite of what one would expect: - http://www.nature.com/nrg/journal/v17/n7/full/nrg.2016.39.html - Abstract: "The recent increase in genomic data is revealing an unexpected perspective of gene loss as a pervasive source of genetic variation that can cause adaptive phenotypic diversity. This novel perspective of gene loss is raising new fundamental questions. How relevant has gene loss been in the divergence of phyla? How do genes change from being essential to dispensable and finally to being lost? Is gene loss mostly neutral, or can it be an effective way of adaptation? These questions are addressed, and insights are discussed from genomic studies of gene loss in populations and their relevance in evolutionary biology and biomedicine." - This is how the ID group views this: - http://www.uncommondescent.com/intelligent-design/the-war-is-over-we-won/ - "Many years ago, I predicted that modern genome sequencing would eventually prove one side of the argument to be right. This review article indicates that ID is the correct side of the argument. What they describe is essentially what ID scientist, Michael Behe, has termed the “First Principle of Adaptation.” (Which says that the organism will basicaly ‘break something' or remove something in order to adapt) This paper ought to be the death-knell of Darwinism, and, of course, “neo-Darwinism,” but, even the authors who report this new “perspective” have not changed their Darwinian perspective. Somehow, they will find a way to tell us that the Darwinian ‘narrative' always had room in it for this kind of discovery. - *** - From the paper: - "However, genomic data, which is accumulating as a result of recent technological and methodological advances, such as next-generation sequencing, is revealing a new perspective of gene loss as a pervasive source of genetic change that has great potential to cause adaptive phenotypic diversity." - Author interview: " The genome sequencing of very different organisms has shown that gene loss has been a usual phenomenon during evolution in all life cycles. In some cases, it has been proven that this loss might mean an adaptive response towards stressful situations when facing sudden environmental changes” says Professor Cristian Cañestro." - “In other cases, there are genetic losses -says Cañestro- which even though they are neutral per se, have contributed to the genetic and reproductive isolation among lineages, and thus, to speciation, or have rather participated in the sexual differentiation in contributing to the creation of a new Y chromosome. The fact that genetic loss patterns are not stochastic but rather biased in the lost genes[pav: IOW, this is where you're going to find the genomic differences between species you compare] (depending on the kind of function of the gen or its situation in the genome in different organism groups) stresses the importance of the genetic loss in the evolution of the species." - Comment: Perhaps God did start life front end loaded!
