The latest entry in the hot-weather laziness debate, which started as, Did homo erectus die out because he was lazy and technologically conservative? A new large-data study of fossil and extant bivalves and gastropods in the Atlantic Ocean suggests laziness might be a fruitful strategy for survival of individuals, species and even communities of species. The results have just been published in the Proceedings of the Royal Society B by a research team based at the University of Kansas. Looking at a period of roughly 5 million years from the mid-Pliocene to the present, the researchers analyzed 299 species’ metabolic rates—or, the amount of energy the organisms need to live their daily lives—and found higher metabolic rates were a Read More ›

The imposition of evolutionary materialistic scientism (aka naturalism) is one of the key issues driving the march of folly in our civilisation. It is also very difficult to discuss as there are some very powerful rhetorical deflectors at work. Sometimes, then, the best thing we can do is to clip from one of UD’s exchanges and headline it so we can see what is going on from the horse’s mouth: _________________________ It is amusing at first (then on deeper reflection, quite saddening) to trace some of the onward discussion in the thread from which the OP comes: JDK, 94: >>Hi JAD. I don’t think there has been anything in this thread about purposelessness. The OP has been about teleological explanations Read More ›

An anthropologist asks: Now go even further back in time to the 17th or 18th century. The number of folks on average living then who could have contributed to your genetic endowment is so large (more than 1,000), and their possible genetic contribution so small (about 0.098 percent for 10 generations back), it would be smoke and mirrors to assert claims about who they were in person. In fact, most of these people left no trace of themselves in your genome. In short, while it can be hard to get your head around the statistics involved, go back more than a few thousand years and you are genealogically related to almost everyone on Earth. Genetically speaking, however, very few of these Read More ›

Though he helped develop it. Recently, a problem has arisen round efforts to create a synthetic cell.  Gerald Joyce, now of the Salk Institute, helped NASA come up with a very widely used definition of life, “Life is a self-sustained chemical system capable of undergoing Darwinian evolution.” But, as medicl historian Rebecca Wilbanks explains at Aeon, In 2009, after decades of work, Joyce’s group published a paper in which they described an RNA molecule that could catalyse its own synthesis reaction to make more copies of itself. This chemical system met Joyce’s definition of life. But nobody wanted to claim that it was alive. We’d certainly have heard about it if they had. But Joyce no longer seems satisfied with that definition. For Read More ›

From previous universe: In Penrose and similarly-inclined physicists’ history of space and time (which they call conformal cyclic cosmology, or CCC), universes bubble up, expand and die in sequence, with black holes from each leaving traces in the universes that follow. And in a new paper released Aug. 6 in the preprint journal arXiv—apparent evidence for Hawking points in the CMB sky— Penrose, along with State University of New York Maritime College mathematician Daniel An and University of Warsaw theoretical physicist Krzysztof Meissner, argued that those traces are visible in existing data from the CMB. Daniel An explained how these traces form and survive from one eon to the next. “If the universe goes on and on and the black Read More ›

For all practical purposes. From the author of Lost in Math: How Beauty Leads Physics Astray, at her blog BackRe(Action) According to Penrose’s conformal cyclic cosmology, the universe goes through an infinite series of “aeons,” each of which starts with a phase resembling a big bang, then forming galactic structures as usual, then cooling down as stars die. In the end the only thing that’s left are evaporating black holes and thinly dispersed radiation. Penrose then conjectures a slight change to particle physics that allows him to attach the end of one aeon to the beginning of another, and everything starts anew with the next bang. This match between one aeon’s end and another’s beginning necessitates the introduction of a new Read More ›

is our ruinous nightmare. This can be seen through a game, from the conspiracism thread: KF, 86: >> . . . there is a silly little mental game we can consider. [The Crooked Yardstick Effect:] Step one, define that a certain crooked yardstick, S, is the standard of straight, accurate and upright. Once that is done, no stick I that is genuinely so can ever conform to S: I != S. So on the S-standard I will always be rejected. This seems silly, until it is in place on an ideologically tainted matter, ask, how can we move from S to the incommensurable I. Only, by interposing a plumbline P that you are willing to accept is naturally upright and Read More ›

As robotics engineer Ken Goldberg explains, What has working with robots taught you about being human? It has taught me to have a huge appreciation for the nuances of human behavior and the inconsistencies of humans. There are so many aspects of human unpredictability that we don’t have a model for. When you watch a ballet or a dance or see a great athlete and realize the amazing abilities, you start to appreciate those things that are uniquely human. The ability to have an emotional response, to be compelling, to be able to pick up on subtle emotional signals from others, those are all things that we haven’t made any progress on with robots. What’s the most creative thing a Read More ›

The Progressive’ war on science reality continues apace.  From healthline.com: Many individuals don’t see body parts as having a gender — people have a gender. And as a result, the notion that a penis is exclusively a male body part and a vulva is exclusively a female body part is inaccurate.

Recently, we reported on one of those Darwinian morality tales, according to which homo erectus died out because he was lazy, compared to the rest of us. Ann Gauger, pointed out that the broader picture (timelines, for example) does not suggest that Homo erectus was lazy. And now we learn, “The inference that laziness typifies Homo erectus and that such a failing might have hastened their extinction is moronic,” says Neil Roach, a biological anthropologist at Harvard University. “This is a solid study with interesting results that do contribute significantly to our field, and unfortunately, the press release does exactly the opposite.” Roach makes his point emphatically, and with good reason—there’s a lot of evidence pointing to H. erectus as Read More ›

From ScienceDaily: There are a couple of key features that make a turtle a turtle: its shell, for one, but also its toothless beak. A newly-discovered fossil turtle that lived 228 million years ago is shedding light on how modern turtles developed these traits. It had a beak, but while its body was Frisbee-shaped, its wide ribs hadn’t grown to form a shell like we see in turtles today. “This creature was over six feet long, it had a strange disc-like body and a long tail, and the anterior part of its jaws developed into this strange beak,” says Olivier Rieppel, a paleontologist at Chicago’s Field Museum and one of the authors of a new paper in Nature. “It probably Read More ›

From ScienceDaily: Together with their sister group the Neanderthals, Denisovans are the closest extinct relatives of currently living humans. “We knew from previous studies that Neanderthals and Denisovans must have occasionally had children together,” says Viviane Slon, researcher at the MPI-EVA and one of three first authors of the study. “But I never thought we would be so lucky as to find an actual offspring of the two groups.” Well, it’s lucky for sure, but it’s the sort of thing we might expect to exist. We just want our team, institution, or country to get the credit. Analyses of the genome also revealed that the Denisovan father had at least one Neanderthal ancestor further back in his family tree. “So Read More ›

ID is a proposition that, first, it is reasonable to inquire scientifically as to whether certain features of the world of life and/or the physical cosmos can or do show observable signs of design. To which, the answer has long since been given, e.g. by the well known OoL researcher Orgel in a significant 1973 book: >>living organisms are distinguished by their specified complexity. Crystals are usually taken as the prototypes of simple well-specified structures, because they consist of a very large number of identical molecules packed together in a uniform way. Lumps of granite or random mixtures of polymers are examples of structures that are complex but not specified. The crystals fail to qualify as living because they lack Read More ›

Last year, David Klinghoffer offered some thoughts on fake news about controversies in evolution in popular media that bear repeating: The supposedly objective investigative news site ProPublica hit all of them — codes, creationism, Kitzmiller v. Dover — in a recent article, going after then-Education Secretary nominee Betsy DeVos, who had mentioned “critical thinking” in her appointment hearing. When a colleague and I challenged their reporting, focusing on a distortion of our education policy that could be verified by published documents on our website, an editor brushed us off, claiming it came down to a “matter of opinion and debate, not fact.” I’ve documented my correspondence with the editor, which I found very revealing. I might have let it drop Read More ›

Historian of science Jessia Riskin wonders if a mechanistic view of life is due for a revival: Today, the tension between active and passive mechanism is still evident, for example, in evolutionary biology. While evolutionary theorists reject creationism, of course, concepts such as adaptation and fitness are in fact grounded in a passive-mechanist view of living structures. That view has traditionally banned any talk of evolutionary agency within living organisms, and instead ascribed their forms and structures to forces acting from outside them. At the same time, evolutionary theory retains an important inheritance from the active mechanist tradition; indeed, active mechanist ideas seem currently to be in the ascendant. Recent work on ‘niche construction’ for example attends to the ways Read More ›
