Uncommon Descent Serving The Intelligent Design Community

Coffee!! So why can we domesticate some animals but not most of them?

Here’s an idea presented at YouTube that got kicked around at an ID-friendly online chips n’ gravy fest: The animal must be able to breed in captivity and must have a social structure in which a human can substitute for an animal. Domesticable animals are rare simply because the combination of necessary features is rare. A human can become the leader of a herd or pack. Note: Domestic cats, like Tom, Dick and Harry (UD editorial assistants) are not herd or pack animals; However, handled by humans early enough, cats tend to put the human in the role of Mommy Cat. That is, they never really grow up. But that hardly matters if they have found a human who will Read More ›

Does dark matter really exist?

From Don Lincoln, Fermi National Accelerator Laboratory, LiveScience: Dark matter remains a powerfully predictive theory for the structure of the universe. It is not complete and it needs validation by discovering the actual dark matter particle. So, there is still work still to do. But this most recent calculation is an important step toward the day where we will know once and for all if the universe really is dominated by the dark side.More. Dark matter could solve a lot of problems, in the same way that the primordial cell of origin of life studies or the ancestral human of evolutionary psychology could. If only they would exist, and make their existence known. Local bets are on dark matter to Read More ›

Evolution muddled human breastfeeding?

From Dean Burnett at the Guardian: There are competing theories about this, but the point is that most other species’ young can do a lot more of the work when it comes to feeding. Human babies can latch, but not much else, so the mother has to essentially do everything. Sometimes that’s totally fine. Other times it’s like trying to insert a water balloon into a wine bottle. A soft, constantly moving, unfathomably precious wine bottle that eventually grows teeth. And the water balloon is incredibly sensitive. And you have to do this a dozen times a day. Even when you’re meant to be sleeping. It may be natural, but breastfeeding isn’t as easy a process for humans as it Read More ›

Scientism hits the skids

From Nathan Cofnas at Weekly Standard: What is really disturbing, though, is that Hawking has flagrantly given up on even the pretense of engaging with actual science. He speaks entirely from authority: I am a scientist. Adopt this political policy that I favor or suffer fire and sulfuric acid. The threatened punishment for noncompliance substitutes sulfuric acid for the regular sulfur (brimstone) that features in old-fashioned religion. As far as the justification for the claim, there is no important difference between this and a religious statement that is supposed to be believed simply because it issues forth from a high priest. That can lead to awkward problems when the promoters of scientism turn out to be less than virtuous. Consider Read More ›

Rob Sheldon on the sun as an “ordinary star”

From Ian O’Neill at Space.com, we learn: Is our sun fundamentally different from other “sun-like” stars? This question highlights an ongoing controversy about whether our nearest star is unique or, in fact, an “ordinary star.” Now, an international collaboration of solar physicists thinks it has an answer. Although the sun is very special to Earth and all of the planets in the solar system, it isn’t unique; indeed, it is driven by the same internal mechanisms as other stars, the researchers said in a statement highlighting the findings of a new study. lMore. Our physics color commentator Rob Sheldon writes to say, This presser made me laugh. Here’s the punch line: “Although the sun is very special to Earth and all Read More ›

Snake sex determination dogma has fallen. Thank the boa and python

From Abby Olena at the Scientist: For more than 50 years, scientists have taken for granted that all snakes share a ZW sex determination system, in which males have two Z chromosomes and females have one Z and one W. But a study, published today (July 6) in Current Biology, reveals that the Central American boa (Boa imperator) and the Burmese python (Python bivittatus) use an XY sex determination system, which evolved independently in the two species. If a f fundamental change like that could evolve independently, something other than Darwin’s nature “hourly adding up” must be at work. But what? An internalized library of possible solutions, as Lee Spetner suggests? Gamble agrees that the next step is exploring other Read More ›

The obstetrical dilemma: Why are human infants helpless at birth?

From Chase Nelson at Inference Review: The typical human gestation times of 38 weeks is, in fact, longer than one would expect for a primate of similar body mass. Instead of arguing for an enlarged brain, then, one might as easily argue for a diminished body mass. Thus, it is in spite of similar periods of gestation that humans are more helpless than other great apes at birth; humans are not born early. Moreover, we wean infants earlier than expected for a primate of our body size, not later. The opposite should be the case if weaning time is a proxy for altriciality, and if the obstetrical hypothesis is correct that altriciality requires more intelligent parents. Fetal development provides additional Read More ›

So what IS this life form?

From Laura Geggel at LiveScience: “Because of the animal’s decomposition, it is difficult to be certain what this animal may have been,” John Hyde, a program leader of fisheries genetics at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center in La Jolla, California, told Live Science in an email. “However, it does resemble a black sea hare (Aplysia vaccaria) that are fairly common in this area.” Sea hares, a group of sea slug species,fall within the class of gastropoda. If the strange animal were a black sea hare, that could explain its large size: A. vaccaria is the largest gastropod in the world — it can weigh as much as 30 lbs. (13.6 kg) and grow as long Read More ›

SJWs stream into science: Don’t cite white male geographers

From Carie Mott and Daniel Cockayne, “Citation matters: mobilizing the politics of citation toward a practice of ‘conscientious engagement’” at Journal Gender, Place & Culture: A Journal of Feminist Geography: Abstract: An increasing amount of scholarship in critical, feminist, and anti-racist geographies has recently focused self-reflexively on the topics of exclusion and discrimination within the discipline itself. In this article we contribute to this literature by considering citation as a problematic technology that contributes to the reproduction of the white heteromasculinity of geographical thought and scholarship, despite advances toward more inclusivity in the discipline in recent decades. Yet we also suggest, against citation counting and other related neoliberal technologies that imprecisely approximate measures of impact, influence, and academic excellence, citation Read More ›

Salvador Cordova Talks about DNA and Non-DNA Inheritance

These are a pair of videos from the AM-Nat Biology conference. I have had lots of other things going on so I’ve been slow getting these up, but Salvador’s talks became more relevant as Dan Graur doubles down to try to prove that the genome is mostly junk. You can get the rest of the talks from the AM-Nat Biology conference (that have been uploaded so far) from here.

Interesting proteins: DNA-binding proteins SATB1 and SATB2

With this OP, I am starting a series (I hope) of articles whose purpose is to present interesting proteins which can be of specific relevance to ID theory, for their functional context and evolutionary history. DNA-binding protein SATB1 SATB1 (accession number Q01826) is a very intriguing molecule. Let’s start with some information we can find at Uniprot, a fundamental protein database, about what is known of its function (in the human form): Crucial silencing factor contributing to the initiation of X inactivation mediated by Xist RNA that occurs during embryogenesis and in lymphoma And: Transcriptional repressor controlling nuclear and viral gene expression in a phosphorylated and acetylated status-dependent manner, by binding to matrix attachment regions (MARs) of DNA and inducing a Read More ›

The ongoing failure of supersymmetry

You know, string theory leads to a multiverse. As described by Columbia mathematician Peter Woit at Not Even Wrong: There’s an interview with Nima Arkani-Hamed here. His talk at the recent PASCOS 2017 conference (real title is second slide “What the Hell is Going On?”) gives his take on the current state of HEP, post failure of the LHC to find SUSY. He’s sticking with his 2004 “Split SUSY” as his “Best Bet”. I’d like to think his inspirational ending claiming that the negative LHC results are forcing people to rethink the foundations of the subject, asking again the question “What is QFT?” reflects reality, but not sure I see much of that. More. It has become a cult. It does not need to be Read More ›

A biologist’s deep wish for Darwinism to make sense

Re J. Scott Turner’s forthcoming Purpose and Desire: From David Klinghoffer at Evolution News & Views, His book, Purpose and Desire: What Makes Something “Alive” and Why Modern Darwinism Has Failed to Explain It, underlines that Turner is not an “anti-Darwinist.” On the contrary, he explains that “I want deeply for it” – meaning the modern theory of Darwinian evolution – “to make sense.” The reasons for his disillusion, which he outlines in this fascinating contribution to the evolution debate, turn upon long-ignored problems with the theory, and counterevidence from the mysterious nature of life itself. It is still a couple of months too early for reviews of Purpose and Desire, but Kirkus welcomes it with a pre-publication starred review Read More ›
