“He [Swamidass] is joined by atheist biologist Nathan Lents who has given his support to the book, believing that it may help Christians who hold to a traditional understanding of the Adam and Eve story, to also accept evolutionary science. “
“Deep phylogenetic incongruence” sounds like journalspeak for “our current phylogenetic tree is a hot mess.”
Layers on layers, systems on systems. Puts one in mind of Darwin’s Warm Little Pond, doesn’t it? Legacy science media should ramp up those Pond graphics. And keep the speculation about random events accidentally producing life coming. Speculate HARDER!
Glad we are talking about this… No need to believe us (though we did warn you). What’s this about “rampant” order in the genome? “Rampant” is a word we associate with disease; it’s not a word we commonly associate with “order.” On the other hand, an order that frustrates the outworkings of Darwinian evolution in favor of an orderly system that produces needed innovations must seem a lot like a disease to some. 😉
Challenging the belief that DNA “floats aimlessly.”
A reader writes: They have a mechanism by which they can mutate a specific part of the DNA, in a pattern and rate that’s different from random mutation.
Researchers: “This approach reveals an unprecedented level of fundamental genomic novelties in two nodes related to the origin of land plants: the first in the origin of streptophytes during the Ediacaran and another in the ancestor of land plants in the Ordovician.” Stuck for what to call this, some of us would call it creationism.
“‘For a long time, we thought that having a lot of protocadherins was only found in vertebrates, so we were really surprised when we found more than 160 of them in the octopus genome,’ said Albertin, in reference to her 2015 paper on the subject.”
One wants to ask, how distinct ARE the genomes of these species that all look the same?
Would it be like mapping a cat’s genome and finding a German Shepherd’s GATTACA in there? What that level of distinction really tells us goes well beyond cats and German Shepherds. Or do the researchers really mean something less highly distinct? What? We search for analogies here.
Those old Descent of Man charts were sometimes fun, showing a bacterium ending up as some poor slob hunched over a workstation. Some sort of moral was always pounded into us by these tales, usually not an uplifting one. But real history is always better and more interesting.
So 2/3 of the time, we have “ de novo emergence from ancestral non-genic sequences, such that homologues genuinely do not exist?” Okay. Somebody better go put their arm around the Selfish Gene. It’s tough being the Last Darwinian. Gene, we did not do this to you. Francis Collins and Craig Venter did this to you. Honest.
Remember the Selfish Gene? Aw, he was just playin’ you guys. You didn’t fall for that, did you?
Researchers: Even between chimps and humans, whose genomes are 99 per cent identical, there are dozens of TFs which recognize diverse motifs between the two species in a way that would affect expression of hundreds of different genes.

Researchers studied the thale cress (an Arabadopsis relative) which can have either a single or a double genome. Genome doubling is not good news: “It’s almost always a bad thing to have too much DNA, but we think that sometimes it makes for a ‘hopeful monster’ that just might flourish.” They seem to have found Read More…
