What'sNEW January - March 2017

31 Mar 2017 What'sNEW about HGT |
All members of the Melainabacteria and Sericytochromatia lack photosynthetic machinery, indicating that phototrophy was not an ancestral feature of the Cyanobacteria and that Oxyphotobacteria acquired the genes for photosynthesis relatively late in cyanobacterial evolution. These words come from a collaboration of Australian and Californian scientists investigating the rise of atmospheric oxygen and the role of cyanobacteria in that process.

In the legend for the figure here they write, "...The three Cyanobacteria classes likely acquired aerobic respiration independently after the rise of oxygen (atmospheric oxygen is represented by the red shading). Squares and triangles indicate acquisitions of complex III, whereas circles and diamonds indicate acquisitions of complex IV. ...Square brackets denote operon fusions, and a red 'X' indicates putative loss of ETCs." The report continues, "If true, we expect that other phyla will exhibit the same pattern for aerobic respiration as the Cyanobacteria—a lack of aerobic respiration in their last common ancestor, with a later acquisition involving lateral gene transfer."
Evolution of photosynthesis and aerobic respiration in Cyanobacteria

The term "origin" appears in the article and title, but it seems to mean "first deployment." Certainly, coordination and testing must follow the acquisition of genes and other genetic components to complete the installation of programs for aerobic respiration, photosynthesis, or any comparable evolutionary innovation. But the "origin" of any complex functional genetic program remains unobserved and unexplained. Meanwhile, evidence for horizontal gene transfer (HGT) grows daily. We think the underlying assumptions about evolution need to be reconsidered.

Facts and Speculations in Cosmology The big bang theory has many committed advocates, but doubts remain among an informed minority. These doubts get a full hearing in Facts and Speculations in Cosmology by Jayant Narlikar and Geoffrey Burbidge (2008). A brief history of early cosmology introduces a more comprehensive story of recent developments, with frequent illustrations and no difficult equations. The authors expose key assumptions unsupported by direct observation (e.g. inflation, cold dark matter, dark energy) that big-bangers must make, and numerous observations (e.g. anomalous red shifts) they must ignore.

These distinguished cosmologists have witnessed the bias with which the story of modern cosmology is usually told. For one example: until 1998, the big bang theory confidently held that the expansion of the universe is decelerating. Then the very opposite, acceleration, was discovered. The shock was quickly swallowed with no mention of an interesting fact: acceleration was a basic prediction of the steady-state theory, the leading alternative. Although the original steady-state theory of Gold, Bondi and Hoyle is now abandoned, a newer "quasi-steady-state" cosmology (QSSC), which Fred Hoyle also helped to develop, is well-explained and supported in the book. Along the way we learn about the contributions of astronomers seldom noticed elsewhere, like Viktor Ambartsumian and Hans Arp, to name only two.

Burbidge and Narlikar confess that no theory today satisfactorily explains all the data, and since 2008, this situation has not improved. Meanwhile, dogmatic support for the big bang inhibits scientific imagination and hinders progress. The dogma also requires life to somehow originate, which, to us, looks forbiddingly improbable.

Landslide on comet 67P
24 Mar 2017
Rosetta saw a landslide on comet 67P. In July 2015, some 20,000 cubic meters of material collapsed from an escarpment that ESA scientists named Aswan cliff. The collapse coincided with outburst of material indicated by an arrow in the upper image, taken from the Rosetta orbiter 10 Jul 2015. (The usual jet activity occurring over the illuminated, bottom side of the comet is also visible.) Five days later, bright water ice exposed by the landslide was photographed. It ablated away, but some, indicated by an arrow in the lower image, was visible more than five months later. Concurrently, surface temperatures up to 340 K were measured. We note that surface overturning, water, warm temperatures and sunlight are hospitable to life.

...we obtained evidence that KZPFs [KRAB zinc-finger proteins] exploit evolutionarily conserved fragments of transposable elements as regulatory platforms long after the arms race against these genetic invaders has ended. Together, our results demonstrate that KZFPs partner with transposable elements to build a largely species-restricted layer of epigenetic regulation. These words come from a study by geneticists in Lausanne, Switzerland, who investigated the evolutionary emergence of KZFP genes in vertebrates and their targets in the human genome.

The chart shows the number of KZFP-like genetic units (including pseudogenes) in indicated genomes, ordered by taxonomic class. To us, the study provides another example of evolutionary progress made possible by pre-existing genetic programs that have been imported into the genomes of receptive species, perhaps in pieces, perhaps long ago.

...the origin of viral replicative modules seems likely to hark all the way back to the precellular era. So say Mart Krupovic and Eugene V. Koonin in another study that compares and classifies conserved protein structures. This time the focus is on the capsid proteins that encase the viral genome. Many of them have homologs that are ubiquitous across life's domains. The conclusion, consistent with others, is that the proteins may be older than cellular life. Viral and cellular SJR proteins

To make sense of this apparent absurdity within a strictly darwinian paradigm, Krupovic and Koonin ultimately imagine unexplained, unobserved "origins." But we endorse their fully-grounded observations: These findings reveal a stronger connection between the virosphere and cellular life forms than previously suspected. ...this view is compatible with the scenario of multiple recruitment events occurring throughout the course of evolution of life.

These words come from an article by an international multi-disciplinary team analysing sediments apparently from ancient hydrothermal vents. If correct, it would mean that life on Earth may have begun even earlier than we thought. It also strengthens that case that life could thrive near hydrothermal vents on ocean worlds like Europa, Enceladus and others.

More and more studies are concluding that life's earliest ancestors were more complex than bacteria. Lately, these conclusions come from research that compares and classifies protein domains, said to be better conserved than genes. Traditionally, it was assumed that the ancestor of the modern tree of life is a minimalist first cell that evolved by accumulating increasingly numerous and diverse coding sequences to reach the complexities of modern genomes. In fact, the root of the modern tree of life seems to be quite complex. ...The only sure thing now is that the common ancestor ...did encode many of the protein domains of all three super-kingdoms.
Evolution of Cells, Genomes and Proteins, a conference at Nanyang Technological University, 1-3 Feb 2016. SCP superfamilies

The distribution of recognized protein superfamilies shows extensive overlap among the 3 domains of life (diagram). The "complexity early" which this distribution reconfirms is a jarring surprise for darwinists. We wish the surprise would prompt them to notice cosmic ancestry, which predicts, "Life can only descend from ancestors at least as highly evolved as itself." Meanwhile, mainstream speculations about the origin of life and the tree of life must be wrong. Two experts in "the structural classification of proteins" (SCOP), discuss its use and implications in a recent interview:

ESPs that have been identified in Asgard archaea Archeae contain many eukaryotic signature proteins (ESPs). Some of them previously identified are GTPases, actin homologues, ubiquitin modifier system components and homologues of eukaryotic protein translocation and glycosylation pathways.

Now more ESPs are seen among a newly-designated clade of archae named Asgard. They include a subunit of eukaryotic DNA polymerase, a eukaryotic ribosomal protein, key components of the eukaryotic cytoskeleton and membrane trafficking proteins. The schematic representation of a eukaryotic cell (right) highlights ESPs that have been identified in Asgard archaea, with colored tables indicating their distribution among those species.

The overall picture indicates that the archaeal ancestor of eukaryotes already contained many key components underlying the emergence of cellular complexity that is characteristic of eukaryotes, this research team says in summary. As darwinists, they suppose that an archaeal ancestor must have had some use for the ESPs after all. But in cosmic ancestry, genes always come first. If they weren't often found in species preceding the need for them, we would be surprised.

...giant viruses present an astonishing arsenal of genes not widespread in the virosphere, some of them related to important steps of the translational process.... This remark comes from a team of French and Brazilian virologists who are especially interested in mimiviruses. These viruses (example pictured) have a genome that resides in a single linear dsDNA molecule of up to ~1,250 Kb that may have ~1,000 open reading frames. Some of the ORFs are genes related to protein synthesis, tRNAs, and translation factors, a complete surprise. Mimivirus FROM

The researchers are specifically interested in the phylogeny and ultimate origin of the mimiviruses. Were their [viral?] ancestors even more complex, or less complex? Despite many theories, the origin and evolution of mimiviruses remains a breathtaking mystery. It is not yet possible to exclude any specific scenario of giant viruses' evolution.

Darwinian logic does exclude the scenario we prefer. In cosmic ancestry, viruses are the main vector for the horizontal transfer (HGT) of cellular genes into species that can use them. We are not surprised if mimiviruses contain genes for tRNAs, protein synthesis, translation factors and more.

Sedimentary organic carbon is oxidized with little recycling. Atmospheric oxygen is controlled by feedbacks on carbon burial.
02 Feb 2017
Earth's atmosphere contained only 2% to 4% oxygen for a billion years, before the arrival of land plants about 470 million years ago. Then photosynthesis doubled. Forty million years later, land animals began to emerge.

We take this synopsis from a comprehensive new study by geographers at the University of Exeter, UK, who modeled the processes in the biosphere that produce and consume oxygen. Its history, including the long stasis, is puzzling. With isotope data, they make a plausible case that mineral, tectonic, biological, climatic, weathering and sedimentary processes with feedback loops can explain it. The study also supports our belief that slow Gaian processes can make a planet habitable, and then more advanced life can develop and flourish without delay.

The mechanism we describe provides a potential explanation for the overall stepwise evolution of atmospheric oxygen on Earth. Recycling of sedimentary organic carbon and its kinetically limited oxidation could have sustained low Proterozoic atmospheric oxygen levels.... The rise of oxygen to present levels simply required an increase in organic carbon burial rate, which may have begun in the Neoproterozoic Era, but in our model was not completed until the mid-Palaeozoic Era with the colonization of the land by plants and fungi, liberating nutrient phosphorus from rocks and producing high C/P material for burial.

Scientists at the University of Chicago have created the first genetically modified animals containing reconstructed ancient genes, which they used to test the evolutionary effects of genetic changes that happened in the deep past on the animals' biology and fitness. ...The specific findings, involving the fruit fly's ability to break down alcohol in rotting fruit, overturn a widely-held hypothesis about the molecular causes of one of evolutionary biology's classic cases of adaptation. University of Chicago

The new method, pioneered in Joe Thornton's lab, apparently opens a new way to study adaptation. In our understanding, adaptation on the scale examined here would be categorized as microevolution. Macroevolution, by contrast, requires wholly new genetic programs that have not been shown to come from adaptive mutations of one or a few nucleotides. Therefore, the same method cannot be simply extended for studying macroevolution. Nevertheless, we are intrigued. ...because of technical and conceptual advances, it should now be possible to experimentally assess the causal predictions of many previously untested or weakly tested hypotheses of historical molecular adaptation....

The population genetic theory replaces adaptationist just-so stories with testable predictions, and research aimed at falsification of these can improve our understanding of evolution. Just-So stories

In a new, wide-ranging essay, Eugene V. Koonin of the National Center for Biotechnology Information, National Library of Medicine, National Institutes of Health, considers the fitness landscapes of prokaryotes (large populations) versus eukaryotes (small populations). The latter allow for greater inventiveness, he concludes. To cope with this inescapable burden [introns], eukaryotes have evolved a global solution, the highly efficient splicing machinery. ...The nucleus itself may have evolved as a damage-control device that prevents the exit of unprocessed transcript to the cytoplasm. (How are these not more "Just-So" stories?)

Koonin is well aware of horizontal gene transfer (HGT) and de novo gene origination: mobile genetic elements (MGE) ...genes have been recruited for essential functions at key stages of eukaryotic evolution. But where the programming for these functions comes from is not a concern to him. If he wants a theory of evolution with testable predictions, may we suggest testing his predictions with quarantined experiments in biology or computer models?

You can see rapid evolution in retroviruses over short time frames, but this is new evidence that they've been around for hundreds of millions of years — Michael Worobey, evolutionary virologist, University of Arizona.

New research provides another example of genetic systems older than standard darwinism expects them to be. The report also confirms that the subject retroviruses can be transferred across diverse species and become permanently installed into their genomes. Genetic programs that look too old, and horizontal gene transfer (HGT) by viruses are phenomena that surprise darwinism and support cosmic ancestry.
