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. When the opposite, acceleration, was discovered in that year, 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.Facts and Speculations in Cosmology, by Jayant Narlikar and Geoffrey Burbidge, ISBN-13: 9780521865043, Cambridge University Press, 2008.

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 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:

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.

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.

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 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....Discovery overturns long-held genetic belief, The University of Chicago Medicine (+PhysOrg.com), 03 Jan 2017; re:

Macroevolutionary Progress Redefined... reconsiders the difference between micro- and macroevolution.
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?Splendor and misery of adaptation, or the importance of neutral null for understanding evolution, by Eugene V.

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.
