If nothing makes sense except in the light of evolution, the light sometimes is shining away from Darwin.Bird stripes: Some evolutionists thought that sexual selection led to color bands in zebra finches. “One of the most replicated experiments in behavioral ecology is the presumed manipulation of male attractiveness in zebra finches by adding red or green color bands,” authors in PLoS ONE said ( Seguin A, Forstmeier W (2012) No Band Color Effects on Male Courtship Rate or Body Mass in the Zebra Finch: Four Experiments and a Meta-Analysis. PLoS ONE 7(6): e37785. doi:10.1371/journal.pone.0037785). Well, Seguin and Forstmeier replicated the experiment and couldn’t confirm any evidence for evolution. “Combining this new experimental data with all the published evidence in a meta-analysis shows that color bands seem to affect neither male courtship rate (average effect size d = 0.02) nor male body mass (d = −0.07),” they said. “…The present case is a reminder that replication of experiments lies at the heart of distinguishing between real effects and false positive findings.”Living fossil fish: past fail, future hope and change: “Living fossils reveal secrets of evolution,” a headline on PhysOrg promised, but alas, no evolution was found in the article. Bichirs are African fish that “posses a number of archaic characteristics that are otherwise found only in fossil fish,” another PhysOrg article stated. A molecular clock analysis of bichirs only offered a possibility to start to begin to commence to “get a better understanding” of how these living fossils might have evolved, despite little change from the fossil record. The project “therefore provided scientists with an important basis for future studies of the anatomical and genetic development of early vertebrates,” the article stated hopefully.Cooperation of the fittest: By PhysOrg‘s own admission, cooperative species are an evolutionary enigma that shouldn’t be:Evolution by definition is cold and merciless: it selects for success and weeds out failure. It seems only natural to expect that such a process would simply favour genes that help themselves and not others. Yet cooperative behaviour can be observed in many areas, and humans helping each other are a common phenomenon. Thus, one of the major questions in science today is how cooperative behaviour could evolve.A new “theoretical model” sounds promising in the article, but allows for opposite outcomes in the computer depending on how multiple factors are tweaked. Natural populations have ways of defeating computer software, so without field work, the model seems a post-hoc rationalization for something Darwin didn’t expect.Youth in Asia: How long have evolutionists postulated humans originated in Africa? Answer: at least since Darwin. Now, however, a new primate fossil is causing some to think the Asians beat the Africans to the punch line. To rescue the textbook story, according to Live Science, “This migration from Asia ultimately helps set the stage for the later evolution of apes and humans in Africa.” Out of Asia, then Out of Africa. Get it?Slim-o-saurs: All the Godzilla movies will have to be re-done. Dinosaurs weren’t the big, lumbering beasts long portrayed in movies. According to PhysOrg, a new study by University of Manchester comparing skeletons living mammals with dinosaur bones, and then calculating the body mass to skin wrapping volume, shows that previous calculations of body mass of large dinosaurs such as brachiosaurs were overestimated by almost 350%.Cave campfires: Wrong again. Evolutionary dating of continuous fire use by human ancestors is off by 250%, according to Nature (485, 31 May 2012, pp. 586–587, doi:10.1038/nature11195). “An analysis of microscopic and spectroscopic features of sediments deposited in a South African cave one million years ago suggests that human ancestors were using fire much earlier than had been thought.”With these upsets in evolutionary theory, the best way Darwinists at Harvard have found to keep new disciples up coming through the ranks is to avoid the Darwin Fail stories, and instead, reach out and touch them with games that create “tree-thinking” – as if students are not already thinking like wooden stumps.A theory so flexible it can accommodate any unexpected data is convenient, accommodating, workable, long-lasting, consensus-building, useful, convincing, practical, stable, functional, pleasing, agreeable, and unscientific.What do we mean by “Darwin Fail?” See BigFail.com for clues, then go to the Darwin Awards.

Do you have any idea how many emergencies are resolved inside your body every day without your conscious knowledge or control? Here are just 3 examples.Sugar cops: The surfaces of many body cells are covered with what look like a thin forest, where the trees are sugar molecules. A recent article on PhysOrg explained how this is a frontier of biology: “The “glycome”—the full set of sugar molecules in living things and even viruses—has been one of the least understood domains of biology, the article said, but the glycome “encodes key information that regulates things such as cell trafficking events and cell signaling.” Largely independent of the genetic code, which builds proteins, the glycome represents another kind of code or signalling system vital to health.Tissue graveyard: When epithelial cells (common in body tissues) die, how are they disposed of? A kind of burial at sea takes place automatically as neighboring cells squeeze out the bad cell, Current Biology said (Current Biology, Volume 22, Issue 11, R453-R455, 5 June 2012, 10.1016/j.cub.2012.04.036). It’s called “crowding-induced live cell extrusion.” This is important because “To maintain a functional and harmonious epithelial society, the number and quality of cells need to be tightly controlled,” Katoh and Fujita emphasized.Immigration policy: “We are not alone,” Michael Balter wrote, but he was not discussing SETI or aliens, he was introducing a special feature in Science last week about the “microbiome,” the set of microbes that travel with us everywhere we go. “Our bodies, inside and out, are teeming with trillions of microbes. Most of them are our friends, helping us to digest food, strengthen our immune systems, and keep dangerous enemy pathogens from invading our tissues and organs.” Needless to say, if our own cells did not keep tight regulation of these alien cells, we would be in constant danger. In his introductory article (Science 8 June 2012: Vol. 336 no. 6086 pp. 1246-1247, DOI: 10.1126/science.336.6086.1246), Balter wrote, “Evidence is building that this resident community of microbes, called the microbiome, plays a major role in health and disease.”We look out our eyeballs like a captain looks out the window of a cruise ship, thinking we are in control of this large vessel we inhabit. But actually, just like the captain of the ship, we are clueless as to what is really going on in the hull. In a large cruise ship with hundreds of employees and thousands of guests, little emergencies happen all the time: a fire in the kitchen, a suspicious character in the wrong place, anomalies in the engine room. If the captain had to know every incident, he would be distracted from steering, for one thing, and wouldn’t know what to do about most problems anyway. Fortunately, each department on the ship has policies and procedures for handling just about every contingency. The captain smiles, hands on the wheel, confident the ship is under control. In our bodies, things are far more precarious. We are beset daily by broken DNA strands hit by cosmic rays or ionizing radiation, unhealthy food materials, improperly folded proteins, and a host of bacteria and viruses that vastly outnumber our own cells. As with the cruise ship, there are built-in policies and procedures for handling most of these situations that operate without our conscious knowledge or control.One biology professor was fond of remarking,”The amazing thing is not that we get sick. The amazing thing is that we are ever well.” Are you having a nice day today? Are you basically healthy? Count your blessings. You have so many trillion helpers inside of you, you could not possibly know what they do or why. Not even our leading scientists have a grasp on all the relationships, signals and pathways involved. We know a little about white blood cells that patrol our internal highways. We know a little about DNA damage repair. We know a little about tissue regeneration and replacement. But far more remains unknown, such as the glycome mentioned above. One thing becomes clearer each passing day: we owe our existence to fantastically complex, interrelated processes that boggle the mind, things that Darwin never knew about when he concocted his little myth.As you peer out the windows of your cruise ship today, smile and enjoy the view, knowing things are under control. Just don’t take so much credit for it. There’s a higher Authority that assigned you your ship, temporarily, with all its crew. Respect the crew and follow the Authority’s orders, knowing you will give an account. With great privilege comes great responsibility.

Comment Preview • The HP Omen X Desktop is for gamers on the edge 1 Review • HP’s PC gaming flagship turns PC gaming on its side The hardware in Metro Exodus’ menu system is practically life size on this monitor. Lori Grunin/CNET Gaming monitor manufacturers love to throw around the term “immersive” when referring to their products — the bigger and curvier it is, the louder the proclamations get. Well, no monitor to date can hold an immersive candle to the HP Omen X Emperium 65. It swallows you whole. I’m lucky it let me out long enough to get this written.It’s also $5,000 (about £3,830 or AU$7,000). So the most frequent question we get is “How is it better than a good 65-inch TV, which costs half as much?” The answer, at least for most people, is it’s not. But for a tiny subset of PC gamers, it’s more fun than a battle royale of monkeys.The Emperium was first announced at CES 2018 as part of Nvidia’s BFGD (Big Format Gaming Display) initiative, but HP is the only manufacturer from the group to have actually shipped a monitor. It feels like a Frankenstein’s monster of features: There’s a 65-inch Nvidia Shield smart HDR TV-slash-monitor that supports Nvidia’s G-Sync adaptive refresh technology and integrates Google Assistant. (So if you value your privacy, you may think of it as a personal-data-collecting portal of doom.) 22 Photos Mentioned Above HP Omen X CNET may get a commission from retail offers. HP Omen X News • HP Omen X 2S gaming laptop sports a second screen HP’s Omen X Emperium 65 and more gaming goodies come to CES 2019 See it Share your voice HP Nvidia $3,199 Gaming Accessories Monitors Tags Despite wanting to throw myself across it and plead with HP to let me keep it a while longer, it’s hard to recommend it as an actual purchase. Partly because pieces of it are bound to obsolesce within the next couple of years and partly because you’re probably better off spending less and putting the money you save into better-performing hardware and more games, at least until gaming figures out where it’s heading — the cloud, your phone, next-gen consoles or someplace as-yet unimagined.And she’ll have fun, fun, funConnected to a PC, the Emperium’s a jumbo-sized equivalent of a great 27-inch HDR (technically, HDR10) monitor like the Acer Predator X27, with similar specs but really, really big. I hooked the Emperium to a Falcon Northwest desktop equipped with an overclocked (to 4.9GHz) Intel Core i9-9900K and dual Nvidia RTX 2080 Ti cards. That’s pretty much the configuration you need to really appreciate all aspects of the Emperium simultaneously — the 4K, HDR and G-Sync.I didn’t see any artifacts, no matter what frame rate I threw at it, whether I went far beyond its native 120Hz (or 144Hz overclocked) or well below it — because 4K at ultra-everything including ray tracing still drops to unplayable frame rates. In this respect, it was one of the best G-Sync monitors I’ve used.While a 27-inch HDR monitor looks great, at 65 inches it really wows. The size alone ramps up Resident Evil 2 from scary-if-you-play-in-the-dark to leave-the-lights-on terrifying.Each game handles HDR differently. And because you’re looking at computer-generated graphics and not the real world depicted in movies, you don’t have the frame of reference to tell you whether a game’s colors look “correct” or the control you need to fine tune them. You just go with what appeals most and make sure the shadows aren’t so dark that you can find the object you’re looking for and won’t get ambushed by a mutant or a zombie. The otherworldly glowing reds and eye-searing brights in Hellblade: Senua’s Sacrifice lend it that extra touch of surreality, so who cares if her face paint probably isn’t the correct shade of blue?The on-screen display. (Aside: Dear Google, can you please suggest “try searching for ‘how to make Google stop suggesting things'” instead? Thanks!) Lori Grunin/CNET I didn’t run a full suite of tests in the short time I had with the monitor, just enough to confirm that it hits the most important marks. In HDR mode it covers 97 percent of the P3 D6500 color gamut — that’s close to one of the best OLED TVs we’ve tested, which hits 98.4 percent (95 percent in SDR). It’s got a typical black level of 0.009 nits (minimum is 0.001). So it’s not OLED-level black, but it’s visibly impressive. It seems to overshoot peak brightness to roughly 1,100 nits and then gradually decline, outputting over 1,000 nits in 5 percent, 10 percent and 25 percent windows.The VA-IPS panel has 384-zone local dimming with no edge bleed that I could spot. It has typical off-axis viewing for the technology, so all but the most oblique angles look good.The soundbar that comes with the Emperium is an aesthetically pleasing, well-built and aurally balanced 2.1 system that fits snugly under the display and can be controlled by the Shield remote. But it connects to the monitor with a surprisingly low-end analog cable. It does have a DSP input.Enlarge ImageOne nice design touch is the automatic lighting strip and illuminated labels. Lori Grunin/CNET There’s a solid selection of connections on the Emperium:Four USB-A (two on each side)One DisplayPort 1.4Three HDMI 2.0 (1 ARC)SPDIFGigabit Ethernet802.11ac Wi-FiBluetoothYou should be able to connect peripherals, such as external storage or wired keyboard and mice via the USB ports, to use with the Shield — that’s what the menus imply. But I couldn’t get it to recognize any USB devices. Even if that’s just a bug, you can’t use the ports as a hub the way you can on a desktop monitor because there’s no upstream USB connection from the PC to the display.Nor did the monitor like our 5GHz network — it kept saying that the signal was weak and refusing to connect, even after I moved the monitor into the same room as the router. A keyboard, mouse and controller all connected through Bluetooth, but the controller especially tended to be too laggy, even for simply navigating Steam.Not ready for the futureIf you take the monitor capabilities out of the equation, the Emperium’s just a pretty good, overpriced Shield TV with the same annoying remote. All non-PC gaming, whether you’re using a console via HDMI or cloud via GeForce Now (GFN), is limited to a 60Hz refresh rate and generally delivers the frame rate to match that, so you don’t need the refresh-rate versatility of the Emperium. Nor do you need a TV this high-end to play games over GFN. In fact, the broad tonal range of the display ends up emphasizing the artifacts — color contouring, desaturation and blockiness — of the compressed stream delivered by cloud-based games. GFN and the Google universe, including Android apps, Play games, streaming and video, adds value to the package, but you can get a box for $180 and attach it to a $2,500 OLED TV for the same capabilities. The sound bar should probably be optional.The Emperium offers fast refresh, but only connected to a PC with an Nvidia graphics card over DisplayPort. The HDMI connection is fixed at 60Hz for 4K. There’s a 1080p/120Hz option in the menu that I didn’t try, but HD on a 65-inch monitor has a pixel pitch you could drive a truck through (you sit much closer while gaming than you would just watching movies) and while it’s nice, it certainly isn’t worth five grand. 60Hz over HDMI is fine for now because console output is fixed there, too. But we’re expecting new consoles from Sony and Microsoft within the next couple of years, and you can bet they’ll have HDMI 2.1 connections to support variable or adaptive refresh technologies.So the Emperium won’t be able to take advantage of one of the most significant technology improvements to come to consoles in a while. And any gamer who’s going to plonk down this much for a monitor probably has a couple of consoles in addition to a power desktop, especially in the age of exclusives.It’s usually unwise to buy the first generation of anything — I’m looking at you, 5G and foldable phones — and while this is a good and polished one, the Emperium 65 is definitely a first-gen product.
