Physics was “hiding its deepest mysteries” thousands of years ago too before anyone uncovered laws for how it works. There are still mysteries in physics, of course, but they are now more basic. The laws are now known. Let’s hope the same proves true for biology.
Puzzle: However, the researchers also found significant fragments of genetic material from another archaic species of human, Denisovans, in the DNA of the Icelanders, and this was something of a surprise. Up to now, Denisovan genes have primarily been found in Australian Aborigines, East Asians and people in Papua New Guinea. So how did these genes end up in Islanders’ DNA? And when?
Remember the guy who showed us a CD of his genome and said this is me? Naw, we didn’t think so at the time either, but read on…
Maybe viral “cold case” detective work will become a new specialty. Newman agree that seniors should be avoid public gatherings but doesn’t think mass quarantine of the entire population is the best strategy because it prevents the development of herd immunity.
SARS-CoV-2 (COVID-19) as a virus. Updated on an ongoing basis.
“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.
