There are plenty of people who know a great deal about evolution, but because of conflicts with their worldview, they reject it outright. — Amanda Townley, new Executive Director, National Center for Science Education Amanda Townley, new Executive Director, NCSE
"Brought up in a creationist home, a scientist fights for evolution,"
Science, 29 Nov 2023.

I'm glad NCSE acknowledges that people who "know a great deal about evolution" may still reject the theory as it is taught in school. They do so because the explanatory mechanism, neo-darwinism, including its modern variants, is implausible and unproven. The actual evidence points elsewhere. NCSE hinders science by ignoring the evidence and demeaning the skeptics, as if they are all unscientific.

Whatever their inconsistencies, all molecular clock estimates published to date indicate that animals began to diversify much earlier than fossils suggest.

There are about 181,000 annotated exons within the approximately 20,000 known, protein-coding human genes. But "the human genome contains over a million autonomous exons" (including the annotated, coding ones.) They were identified using the 3' and 5' splice sites which characterize them. These findings reinforce speculation that much of the "dark matter" transcriptome may be a by-product, or even an expected component, of the regulation of known genes, as well as a source of novel genetic entities. If the extra exons contain potentially useful genetic programming, with no evidence of neo-darwinian trial-and-error, cosmic ancestry gains implicit support.

The Immense Journey by Loren Eisley
With the failure of these many efforts science was left in the somewhat embarrassing position of having to postulate theories of living organisms which it could not demonstrate. After having chided the theologian for his reliance on myth and miracle, science found itself in the unenviable position of having the create a mythology of its own: namely the assumption that what, after long effort, could not be proved to take place had, in truth, taken place in the primeval past.
Loren Eisley (1907-1977) was a respected anthropologist, ecologist and essayist. He drew deep satisfaction and wonder from the majesty of life, describing it in rich, resonant prose. When his collection of fourteen essays, The Immense Journey, was published in 1957, it became a surprise bestseller. The above quotation appears in the final one, "The Secret of Life." Another one, excerpted next, is titled "The Flow of the River."
...more delicate, elusive , quicker than fins in water, is that mysterious principle known as "organization," which leaves all other mysteries concerned with life stale and insignificant by comparison. For that without organization life does not persist is obvious. Yes this organization itself is not strictly the product of life, nor of selection. Like some dark and passing shadow within matter, it cups out the eyes' small windows or spaces the notes of a meadowlark's song in the interior of a mottled egg. That principle—I am beginning to suspect—was there before the living in the deeps of water.

SARS-CoV-2 RNA suddenly spiked and remained high in the sewage of Florianopolis, Brazil When and where did COVID-19 first infect people? A comprehensive review of this issue, looking at archived samples from around the world, indicates that human infections became widespread earlier and more rapidly than previously known. For example, in mid-November 2019, SARS-CoV-2 RNA suddenly spiked and remained high in the sewage of Florianópolis, Brazil (graph). Blood and tissue samples from France, Italy and the US Northwest tell a similar story. So the evidence is clear that the virus was circulating both in China and internationally by November 2019 at the latest. We can also say with strong confidence that it was not circulating prior to July 2019, and it may not have been around before October 2019....

Where did the coronavirus that caused the pandemic come from? The rapid worldwide detection indicates that it was spread by global winds, not strictly by personal contact. And remember, there was an airburst high over Northeast China, 11 Oct 2019 – likely the remains of a spent comet whose orbit Earth was crossing. These facts make cometary panspermia hard to dismiss as a possible source for the virus. Immunologist and panspermia affiliate Ted Steele comments:

Another new understanding of evolution comes from non-biologists. It begins, ...a new approach to understanding and quantifying selection is necessary. I notice the reluctant acknowledgment that the consensus theory of evolution doesn't work — that should be the headline. But, since anti-scientific creationists would also welcome that announcement, quieter is better. And the opening must be immediately filled. Hence, "Assembly Theory." ...By reimagining the concept of matter within assembly spaces, AT provides a powerful interface between physics and biology.

A new law of evolution is proposed by an interdisciplinary team including geochemist Robert Hazen of the Carnegie Institution for Science. We ...propose a time-asymmetric law that states that the functional information of a system will increase over time when subjected to selection for function(s). ...we propose a 'law of increasing functional information.' The PNAS paper was supported by research grants from the Templeton Foundation, NASA and Carnegie. Information theorist Stuart Kauffman was among those reviewing early drafts. Under "Results," the team makes clear that the new law pertains to everything including life. It's getting a lot of notice.

Viruses: A Natural History, by Marilyn J. Roossinck Viruses by Marilyn Roossinck is the best primer about them you are likely to find. The variety of viruses, in form and genetic system and capacity, is much more than most people realize. Roossinck pays attention to their effects on animals and plants; many individual species of viruses are featured in illustrated two-page chapters with territory world maps. Also discussed are vaccination, innate and acquired immunity, mosquitoes, control of host behavior, the Spanish flu, pioneering researchers like Rosalind Franklin and more. I especially like the colorful illustrations and charts on almost every page. Suitable for your coffee table!

Roossinck well knows that most viruses cause no harm, and that viruses are often endogenized. She even comments, "About 30% of the protein adaptations that make us human have been shaped by the viruses that infected our ancestors." She knows that viruses are everywhere, they are easily transferred, and the vast majority of them are completely unknown. But she makes no extrapolation from these facts, and her chapters on evolution are strictly conventional.

From my cosmic ancestry perspective, the implications are overwhelming. Given the ubiquity of viruses, we animals and plants must get new exposure every day. That gives macroevolution a ready and credible mechanism. I am susprised that mishaps like birth defects and disease aren't even more frequent. How do our systems safely cope with that genetic traffic? And what potential would lie in the vast store of unknown genes that viruses carry?
