So, in other words, these plankton evolved (randomly, so we are told) a highly successful genome that’s entirely different from the type that most life forms have. Well, if you are skeptical of Darwinian claims that it all happened randomly but just once, how about (at least) twice? Increasingly, Darwinism – or whatever it is that they want to call that stuff nowadays – is for true believers.
If a big survey of the giraffe genome can’t tell us the answers to the most puzzling questions about one of the most remarkable animals, where should we look for answers next?
Darwinism’s key strength is that it is much simpler and more straightforward than life forms are.
This is a problem, all right. But really, why do these, or any life/quasi-life forms, have a “genetic alphabet” (an alphabet of life, not learning) at all if everything happened by natural selection acting on random mutation, as the textbooks claim? Let alone an alphabet of life they can just substitute some other letters for? Is there anyone out there who can do the math?
Also: “The work revealed that the last surviving kākāpō population, isolated on an island off New Zealand for the last 10,000 years, has somehow purged deleterious mutations, despite the species’ low genetic diversity.” Hmm.
One senses that the reconstruction will be subject to considerable revision. It’s not entirely clear what “ancestry” means in a world of rampant horizontal gene transfer.
They were only discovered in 1977 and they get more unusual all the time: Microbes called archaea package their genetic material into flexible shapes that flop open in unusual ways, Howard Hughes Medical Institute (HHMI) Investigator Karolin Luger reports March 2, 2021, in the journal eLife. “Very much to our surprise, we found that these Read More…
U Buffalo: “Researchers analyzed the dog’s mitochondrial genome, and concluded that the animal belonged to a lineage of dogs whose evolutionary history diverged from that of Siberian dogs as early as 16,700 years ago.”
At The Conversation on junk DNA: Bewilderingly, scientists found that the non-coding genome was actually responsible for the majority of information that impacted disease development in humans. Such findings have made it clear that the non-coding genome is actually far more important than previously thought.
At Sapiens: Thanks to this work, we now know details about Neanderthals that the archaeological record alone could never have provided. For example, fragments of DNA from specimens found in Spain and Italy showed that at least some Neanderthals likely had pale skin and reddish hair—although, interestingly, the variations for this coloring are different from the variants found in modern humans. Apparently, redheads among Homo sapiens evolved separately…
Some of us remember when we were 99% chimpanzee… But that is so last decade … This type of finding makes more sense. If we were really 99% genetically similar to chimpanzees, the logical deduction is that the genome doesn’t tell us much about a life form. Would be nice if it did, right?
AI natural language processors analyze sentences in human languages but the human genome is a language with sentences too.
We remember when genetics was simple and determinist.
All of this attempted reconstruction depends on the assumption that the platypus is not just an oddity of nature but a manuscript of genetic changes. Well, we shall see.
Researchers: Achromatium is special in many respects: It is 30,000 times larger than its “normal” counterparts that live in water and owing to its calcite deposits it is visible to the naked eye. It has several hundred chromosomes, which are most likely not identical. This makes Achromatium the only known bacterium with several different genomes.
