New use for “junk DNA”: Controlling fear

Okay, why, until recently, did researchers think that “the majority of our genes were made up of junk DNA, which essentially didn’t do anything”? Because that vast sunken library of dead information (sheer randomness and waste) was a slam dunk for Darwinism, as politically powerful theistic evolutionist Francis Collins was quick to point out in The Language of God. (2007). If that’s not true, an argument for Darwinism is disconfirmed.

Researchers think they know how chromosomes came to exist

At Quanta: “Now, in a paper appearing today in Science Advances, an international team of researchers led by Daniel Rokhsar, a professor of biological sciences at the University of California, Berkeley, has tracked changes in chromosomes that occurred as much as 800 million years ago. They identified 29 big blocks of genes that remained recognizable as they passed into three of the earliest subdivisions of multicellular animal life.” Okay, but all this information exploding such a long time ago… ?

At Scientific American: Salamander “junk DNA” challenges long-held view of evolution

Douglas Fox at SciAm: The salamanders would be on death’s door if they were human. “Everything about having a large genome is costly,” Wake told me in 2020. Yet salamanders have survived for 200 million years. “So there must be some benefit,” he said. The hunt for those benefits has led to some heretical surprises, potentially turning our understanding of evolution on its head.

Tim Standish on those five new alternate genetic codes in bacteria: It’s way more complicated than they are making out.

Standish: Changing codon meaning isn’t merely a tweak. As one of the authors notes, “It’s just mind-boggling that an organism could survive that.” But he is dead wrong when he says, “Stop codon shifts are considerably less ‘dramatic’”. Changing a stop codon seems significantly more challenging than changing any other codon meaning because the mechanism for stop codon recognition is totally different and involves more than RNA-RNA interactions.
