The entire history of Kettlewell’s Peppered Moth experiment is littered with problems: doctored photographs, wrong assumptions and slim evidence, followed by genetic analysis revealing that the protein exons coding for color were not changed, but, rather, a transposon (non-random) was inserted in an intron (“junk DNA”). And now there’s this paper. It seems that the […]
From a PNAS article: The conditions of methane (CH4) formation in olivine-hosted secondary fluid inclusions and their prevalence in peridotite and gabbroic rocks from a wide range of geological settings were assessed using confocal Raman spectroscopy, optical and scanning electron microscopy, electron microprobe analysis, and thermodynamic modeling. Detailed examination of 160 samples from ultraslow- to […]
The Cambrian Explosion, demonstrated time and again to be an ‘explosion,’ is a problem for Darwinian theory. Darwin postulated gradualsim; in fact, he insisted upon it when pressed by supporters to modulate this position of his. The problem is that multiple life forms are required to “build” new life forms. You need lots of species […]
Scientistsdiscover the biggest seaweed bloom in the world: From Phys.Org:(https://phys.org/news/2019-07-scientists-biggest-seaweed-bloom-world.html) [N.B. I find the newest version of WordPress almost impossible to work with. There is no correlation between the commands they tell you to use and what actually happens. This might be the last post I post here. There’s no way I can set up […]
Termite nests are a unique example of architectural perfection by insects.
The study shows how comb jellies evolved from ancestors with an organic skeleton.
The main thesis of Behe’s new book, Darwin Devolves, surrounds what Behe calls “poison-pill” mutations, which gives an organism a quick fix, but which can run the risk of being rendered incapable of utilizing future needed adaptations. IOW, breaking and blunting genes to adapt to new environments become changes that get locked in due to […]
In a previous post, I indicated that Dr. Frances Arnold’s Nobel Prize in Chemistry points out that Artificial Selection is more powerful a force than Natural Selection. In a new paper, the authors show that the idea of the ‘gradual’ evolution of foraminifera turns out to be wrong and that what actually happens is an […]
There’s been quite a lot of conversation about our three newest recepients of the Nobel Prize in chemistry, partially, if not principally, because one of the three was a woman, Dr. Francis Arnold. We’ve also read that Dr. Arnold, having gotten nowhere using “rational design” then turned to “evolution,” and with this switch in methodology […]
Here’s a new paper form Nature Communications describing a discovery of a new geometric shape that is apparently found only in curved epithelial cells. I find it intriguing that this shape is entirely new, not found elsewhere in nature, but now coined “scutoids” by the authors, and is proposed as making “possible the minimization of […]
There’s a paper out in Nature Genetics discussing “chromatin topology.” Here’s the abstract: A long-standing question in gene regulation is how remote enhancers communicate with their target promoters, and specifically how chromatin topology dynamically relates to gene activation. Here, we combine genome editing and multi-color live imaging to simultaneously visualize physical enhancer–promoter interaction and transcription […]
From PhysOrg this morning, in a study using “DNA bar-codes” (mitochondrial DNA, using a specific gene COI) and conducted around the world, here’s the verdict: The study’s most startling result, perhaps, is that nine out of 10 species on Earth today, including humans, came into being 100,000 to 200,000 years ago. “This conclusion is very […]
Here’s a recent paper dealing with the deadly and devastating hurricane Harvey which hit the Gulf last year. I haven’t looked at very much of the paper; however, their basic take on it is that the ferocious effects of Harvey can be explained by the OHC (Ocean Heat Content) of the Gulf’s surface waters. And, […]
At Phys.Org there’s a press release that talks about how “information” can be “hidden” in plain text. They use some kind of ‘perturbation’ method, which, I suspect is linked to some kind of set of statistics. Here’s what they say: Computer scientists at Columbia Engineering have invented FontCode, a new way to embed hidden information […]
I wonder what you make of this “Keeling Curve.” I especially wonder what you make of the inset–which can be seen to oscillate on the actual graph of this ‘curve’ below the inset. This might be a very teachable moment. I await your brilliant responses.
