iso-propyl cyanide molecule Even more complex organic molecules have been found in space. A collaboration of German and US astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), in Chile, detected an iso-propyl cyanide molecule, i-C3H7CN (illustrated), with a branching structure, in a star-forming region 27,000 light years from Earth. Analysts are remarking that branched organic molecules must be easier to make, non-biologically, than previously suspected. However, the possibility that the molecules are post-biotic should not be ignored.

What are the genetic programs that distinguish monkeys, apes and humans from other mammals, and where did the programs come from? Answers to these questions are suggested in a report from three computational and systems biologists at the Genome Institute of Singapore. They identified 23,849 anthropoid-specific constrained (ASC) regions with "robust functional signatures," a large fraction of which "were highly enriched in loci associated with fetal brain development, motor coordination, neurotransmission, and vision." These ASCs were among 268,000 identified Anthropoid Constrained (AC) regions, but only the anthropoid-specific constrained (ASC) regions showed no constraint among non-primates. Their median length was 276 bp. Genomic Distribution of Constrained Elements

The Singapore team noted, "Of the ASC base pairs, 99.7% were noncoding, suggesting that novel anthropoid functional elements were overwhelmingly cis-regulatory." The importance of reguatory changes is already well-known, but this high fraction is still surprising.

They also observed, "Unexpectedly, transposable elements (TEs) contributed to >56% of ASCs...." We are not surprised by this, because, in cosmic ancestry, genetic elements that are imported, multiplied, relocated and tested, like TEs, are essential for evolutionary advances.

The most interesting part, to us however, goes unremarked by the Singapore research team. Consider the regulatory ASCs that enable the major advances, in anthropoid vision and nervous systems, for example. Many of them are present in non-primates as well. But there they are unconstrained — not in use. Why is programming for those anthropoid-specific features there at all?

Genetic programs that are available before they are deployed confound strict darwinism and confirm cosmic ancestry.

10 September 2014 What'sNEW about HGT |
Reconstruction of evolution in groups of closely related bacteria and archaea reveals extremely rapid and highly variable flux of genes in evolving microbial genomes, [and] demonstrates that extensive gene loss and horizontal gene transfer leading to innovation are the two dominant evolutionary processes....

...A quantitative assessment of the contributions of vertical inheritance and HGT [Horizontal Gene Transfer] to the evolution of prokaryotes based on the topological comparison of thousands of phylogenetic trees suggested that nearly two-third of evolutionary events originate from HGT. Furthermore, evidence has been presented that HGT rather than gene duplication is the principal contributor to the evolution of gene families in prokaryotes.

Gain and Loss of Genes ...Some groups appear to have vast, "open" supergenomes.

The analysis of prokaryotic genome dynamics described here unequivocally shows that rapid gene flux involving extensive loss of genes and families, partially balanced by gain of new gene families via HGT, is the principal mode of microbial evolution. Indeed, the estimated rates of gene family gain and loss in some groups of bacteria are such that multiple genes appear to come and go over the time required for a single nucleotide substitution to occur in an evolving gene.

Given that the great majority (typically, around 90%) of nucleotide substitutions in evolving microbial genomes are silent and even among those that affect protein sequences, many are effectively neutral, it seems indisputable that the rapid gene flux is the most important route of change in prokaryotic evolution. Notably, the present results show substantially greater rates of gene family loss and gain compared to family contraction and expansion rates. Thus, the gene flux is not only rapid and extensive but often leads to qualitative changes in the gene repertoires. In general terms, these results emphasize that prokaryotic evolution is largely driven not by small variations, such as single nucleotide substitutions, but by much more dramatic changes brought about by HGT and gene loss.

These words come from a new article by five recognized experts at NIH who conducted a comprehensive analysis of the genome dynamics in 35 groups ...of closely related microbial genomes. To us these observations reaffirm the case for a complete paradigm shift in the theory of evolution — for prokaryotes. No longer is the neo-darwinian process of mutation-and-selection expected to account for much: ...Extreme divergence of duplicated genes that could lead to the appearance of a new family is highly unlikely on the short evolutionary scale of an ATGC [Alignable Tight Genome Cluster]. Clearly, the mainstream account of new genetic programs among prokaryotes is awash. The apparent new source is HGT. But this paradigm shift is not getting the attention it deserves.

We expect a corresponding paradigm shift — for evolution among eukaryotes — also to emerge. There, too, the evidence favoring HGT is overwhelming and the paucity of evidence for neo-darwinan creation of new genes is scandalous. Meanwhile, in cosmic ancestry, HGT is the expected source for new genes.

Our analyses revealed that the set of known underground reactions has a significant potential both to increase fitness in existing environments and to exploit new nutrient sources. These words come from a study by a mostly European interdisciplinary team who catalogued and analyzed the known, unexpressed catalytic activities available to E. coli. They go on to conclude:

...Our in silico results suggest that the known underground repertoire of E. coli enzymes can substantially increase the range of utilizable carbon sources available to this organism.... We speculate that the contribution of underground metabolism to adaptation to new environments might be even more pronounced in eukaryotes, where metabolic network expansion by means of horizontal gene transfer has a less prevalent role compared with bacteria.

The analysts are puzzled to note that the studied "underground reactions" apparently have not been exploited so far. They guess that the environments where the reactions might be helpful have simply not been encountered. And they found "no evidence" that the unexploited reactions might be harmful, lest that might be supressing their expression. They do not ask how the helpful catalysts might have evolved by darwinian trial-and-error if there were no trials. But for several hundred, only-beneficial catalysts, isn't that an obvious question?

In cosmic ancestry, all genetic programs are very old, and they must be installed, virtually complete, before they can be activated for testing and, if deployed, optimization. We think this analysis of underground reactions supports our view.

Evolution by subfunctionalization is a related What'sNEW item, 23 Oct 2012.

We also suggest that this study may further explain the 2008 announcement that cloned, quarantined E. coli had evolved aerobic citrate metabolism. Links about that long-running experiment are at > Lenski et al. on the webpage "In Real or Artificial Life, Is Evolutionary Progress in a Closed System Possible?"

CORRECTION, 18 Aug: In this posting we ask "how the helpful catalysts might have evolved by darwinian trial-and-error if there were no trials." We mistakenly thought that the underground reactions were encoded by DNA strands different from the ones encoding the primary catalysts (as in common examples of subfunctionalization following gene duplication.) No. The underground reactions in this in silico analysis are, in most cases, among the capabilities of the primary catalysts, which were expressed. However, all of these reactions are confined to narrow ranges, close to the primary activity, in our observation. An occasional apparent exception is not sufficient to generalize this phenomenon as broadly as darwinists do. If the phenomenon were so broadly capable, it should be be possible to demonstrate in quarantined experiments. So far it isn't. Of course, we regret our misunderstanding.

Third Way Logo The vast majority of people believe that there are only two alternative ways to explain the origins of biological diversity. One way is Creationism that depends upon supernatural intervention by a divine Creator. The other way is Neo-Darwinism, which has elevated Natural Selection into a unique creative force that solves all the difficult evolutionary problems. Both views are inconsistent with significant bodies of empirical evidence and have evolved into hard-line ideologies. There is a need for a more open "third way" of discussing evolutionary change based on empirical observations.

7 July 2014 What'sNEW about HGT |
There is also compelling evidence that not only may mutations be non-random but horizontal gene transfer too need not be random. Enterococcus faecalis, a gutdwelling bacterium, can be resistant to certain antibiotics if it contains [a specific] plasmid.... This plasmid can be horizontally transferred from a donor with the plasmid to a recipient initially without it, through the process of conjugation (bacterial sex). The remarkable feature of this organism, however, is that the transfer is controlled by and initiated by signals sent from the recipient.

These words come from a 2010 essay, by Nigel Goldenfeld (pictured) and Carl Woese, that argues for a new, physics-based perspective on biology. We think their dissatisfaction with the Modern Synthesis — its very foundation is questionable — is not overstated. We note that one problem they highlight, the speed of evolution, is easily solved with horizontal gene transfer (HGT).

Thanks Thanks, Philip Cunningham, for pointing to the quoted article in discussion at Horizontal gene transfer more common than thought, Uncommon Descent, 2 Jul 2014.

Goldenfeld and Woese also comment: Experiments on digital oganisms are an accurate and informative methodology for understanding the process of evolution because the entire phylogenetic history of a population can be tracked, something that is much more difficult–but not impossible–to do with natural organisms. Experiments on digital organisms can be performed over time scales relevant for evolution, and can capture universal aspects of evolutionary processes.... If the physics-based perspective is to prove fruitful, evidence might first appear in digital experiments. We will continue to watch for that. The essay is well-written and thought-provoking.

2 July 2014 What'sNEW about HGT |
Our results show that effective inter-domain transfers and subsequent adaptation of a prokaryotic gene in eukaryotic cells can happen at an unprecedented magnitude. ...Indubitably, HGT can enable acquisition of entirely novel functions, which is more drastic than the gradual evolutionary processes that rely on modification of pre-existing genes and may enhance ecological opportunities. In this context, the prokaryotic gene pool can serve as a large reservoir of potential functions for eukaryotes. Indeed, it appears that prokaryote-to-eukaryote inter-domain HGT events are more prevalent than eukaryote-to-eukaryote ones.
