Two Fossil Explosions Are Better than One

first_img“If one is good, two is better” might work with cookies, but not with headaches.  Evolutionary paleontologists have just gotten a second headache and seem almost happy about it.  How can this be?  Read this article in Science Daily to learn how some evolutionists seem to be masochists.  As if the Cambrian Explosion were not a big enough problem for Darwinian gradualistic views (04/23/2006, 03/28/2007) here comes the Precambrian Explosion.    Using the evolutionists’ geologic timescale, it appears that fossils of mysterious organisms called the Ediacaran biota appeared abruptly without precursors.  Although this problem has been known before (see 12/23/2002, 08/19/2004), a team of scientists from Virginia Tech decided to check out the paleontology and diversity of these organisms that appeared, diversified within limits, and then went extinct some 15 to 40 million years before the Cambrian “radiation” (a scientific euphemism for explosion).  They published their ‘dynamite’ results in Science.1  Because the Avalon group is the earliest of three assemblages of Ediacara, each of which appears abruptly, they dubbed the phenomenon of their sudden appearance “the Avalon explosion.”    Nowhere did they account for this phenomenon in Darwinian terms.  Nor did they even consider pre-empting the charge that might surely come from creationists who would argue this amounts to a double falsification of evolutionary theory.  Instead, they began to see a pattern: if abrupt appearance is the norm, maybe this is how evolution works!  In the new view, evolution simply explodes life into morphospace (i.e., the space of possible body plans).  The final paragraph of the paper explains:What might have led to the rapid morphospace expansion in the Avalon assemblage, and what might have constrained the Ediacara morphospace from further expansion or shift in the subsequent White Sea and Nama assemblages?  We consider a long, undocumented period of Ediacara history before the Avalon assemblage to be unlikely.  The rapid increase of morphospace at the beginning of Ediacara evolution parallels the disparity patterns of the Cambrian explosion: a rapid evolution of body plans followed by taxonomic diversification within the limits of a predefined morphospace.  Various environmental, ecological, and developmental factors have been proposed to explain the rapid evolution of animal body plans during the Cambrian explosion, as well as to account for post-Cambrian constraints on modifications of these basic body plans despite taxonomic diversification.  In principle, these explanations may also be applied to the Avalon radiation…. Regardless of the veracity of these causative explanations, the marked parallels between the Cambrian and Avalon explosions suggest that the decoupling of taxonomic and morphological evolution is not unique to the Cambrian explosion and that the Avalon explosion represents an independent, failed experiment with an evolutionary pattern similar to that of the Cambrian explosion.The way one co-author put it, “Accelerated rates may characterize the early evolution of many groups of organisms.”  Evolution itself was never in any doubt.  Now they “know” that evolution works at accelerated rates.  Darwin had insisted that evolution was slow, operating by the “gradual accumulation of numerous, successive, slight modifications.”    Science Daily indicated that the team was surprised at what they found.  “Surprisingly, … these earliest Ediacara life forms already occupied a full morphological range of body plans that would ever be realized through the entire history of Ediacara organisms,” the article says.  They knew Charles Darwin had been concerned about the Cambrian explosion way back in the 19th century.  Now, here was another explosion just like it.  His branching tree pattern, or expanding cone of diversity, is wrong:“The explosive evolutionary pattern was a concern to Charles Darwin, because he expected that evolution happens at a slow and constant pace,” said Shuhai Xiao, associate professor of geobiology at Virginia Tech.  “Darwin’s perception could be represented by an inverted cone with ever expanding morphological range, but the fossil record of the Cambrian Explosion and since is better represented by a cylinder with a morphological radiation at the base and morphological constraint afterwards.”How can a cylinder with all the radiation at the base be reconciled with an evolutionary view?  The scientists did not attempt to answer that question.  “Scientists are still unsure what were the driving forces behind the rapid morphological expansion during the Avalon explosion,” the article ended.  Xiao commented, “But, one thing seems certain — the evolution of earliest macroscopic and complex life also went through an explosive event before to [sic] the Cambrian Explosion.” 1.  Shen, Dong, Xiao and Kowalewski, “The Avalon Explosion: Evolution of Ediacara Morphospace,” Science, 4 January 2008: Vol. 319. no. 5859, pp. 81-84, DOI: 10.1126/science.1150279.OK, that’s it.  It’s over.  Darwinists, give up!  How many times does the evidence have to falsify your theory before you admit that this little worldview experiment was a bad trip?  We are no longer going to allow you to believe in free lunches (08/07/2007).    For an experience in complete bewilderment at the propensity for the human mind to cling to a false belief, read the Science Daily article in its entirety.  This team of scientists has just seen a very non-evolutionary picture staring them in the face, and all they can see is evolution.  “Well, what do you know – evolution proceeds explosively instead of gradually!”  It’s enough to make one despair of the human condition.  To despair even more, ponder the fact that these falsifications of Darwinism keep appearing at the very time the Darwinists and all the leading scientific societies are on the warpath to stamp out all opposition to evolutionary teaching (see 01/02/2008 entry and a story on Evolution News).  The inmates are running the asylum.    Cryptanalysts look at noise for evidence of a message.  Archaeologists look at markings to look for evidence of an intelligent culture.  Intelligent design scientists look at patterns in improbable structures for evidence of purposeful intent.  SETI scientists look at stellar noise for evidence of a signal.  Darwinists look at signals for evidence of noise.(Visited 31 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Mac App Store Tops 1 Million Downloads in Day One: Here’s What’s Hot

first_imgIn the Mac App Store’s free chart, the newly launched official Twitter application now stands at number one. The app, which notably ditches some of Apple’s recommended design considerations (its close, minimize and zoom buttons, for example, are black not red, yellow and green), has led to a love it or hate it experience among Apple fans. (John Gruber has a good essay on the pros and cons).Clearly, the majority of the end users love it – well, they love it enough to install it and give it a shot, that is. Again, watching the charts over the coming weeks will tell us more about the app’s long-term position.The top 12 free apps, as of this morning, are:TwitterSolitaire Greatest HitsEvernoteSketchBook ExpressCaffeineswackettMindNode for MacSoundCloudTextWranglerStuffit Expander AlfredVirusBarrier Express?We would imagine that many of the downloads from the Mac App Store come from new Mac users who have moved from the Windows world to OS X and are unfamiliar with the offerings available to them in the Mac universe of applications. For those folks, having a curated collections of organized apps will help them get up to speed and be productive on the new platform.Does this Prove the App Store Model for Desktops?Whether or not this same App Store model will work back in the Windows world, is still unknown. Intel launched its AppUp Center, an app store mostly designed with netbook users in mind, but a startup called AllMyApps, wants to more broadly address the app needs of the Windows market.Silicon Valley tech pundit Roberrt Scoble recently admitted that he was not excited about the initiative and “was a jerk” to the founder at the LeWeb conference in December, but AllMyApps CEO Thibauld Favre, stood up for himself and his vision, even thanking Scoble for being challenged. Favre countered Scoble’s claim that Windows users don’t “load new apps” by saying the reason for that is “not because they are Windows users but because without a real application store, they just cannot do it.”An app store, he said, “provides…a great integrated user experience, which makes discovering and managing apps fun,” and for developers, “makes distribution more effective.” That may be true, but Apple users are an entirely different beast than Windows users. Will they want or need a collection of browsable apps? Or will they think, hmm, I need some apps – I’ll just search the Web…?Disclosure: Intel AppUp is a ReadWriteWeb sponsor, on ReadWriteHack.

The company has announced this morning that the number of downloads from its newly launched Mac App Store surpassed 1 million within the first 24 hours.The store, which launched yesterday morning to bring a centralized repository of OS X compatible applications to Mac users, now includes over 1,000 free and paid software programs. And as with iTunes, the apps are organized by category, are ranked by top paid, free and top grossing, and are rated and reviewed by customers.According to Apple CEO Steve Jobs, the company is “amazed at the incredible response” the store is getting. Given that there are 50 million Mac users in use worldwide, it’s not really all that surprising to us, however. But it’s a great start, nonetheless.Top Paid AppsAs of this morning, the top paid charts featured a collection of Apple software programs like iPhoto, iMovie and Pages as well as games, including the ever-ubiquitious Angry Birds, which soared in to the number one spot. It’s unclear if Angry Birds’ rise was at all affected by the recent reports of Mac App Store piracy.To catch you up: apparently, Rovio, the creators of Angry Birds, in addition to many other Mac App Store developers, neglected to follow Apple’s guidelines on validating App Store receipts for purchases. A Web Developer’s New Best Friend is the AI Wai…center_img What this means is that, for some applications, you could copy the receipt from any other Mac App Store download (even free apps) into a copy of the paid app you want to use and it will run.The procedure for doing so is a bit more hacker-y than some news reports have implied, though. You have to delve into the Package Contents of the app’s dmg file, navigate to a particular folder and delete specific files. You then copy and paste those same files from the free app’s folder to the paid one. In other words, you would need to know these specific instructions before doing this – it’s not a matter of simply copying-and-pasting a receipt number, like you would have on some brick-and-mortar retail store’s receipt, into a field or pop-up notification within the paid app.For average to fairly technical users, the hack is a piece of cake. But for the millions who chose Mac because “it just works” and who were stymied by the complexities of Windows systems, even a simple hack like this is likely over their heads.That being said, it will be interesting to watch the ratings to see if anything changes with regards to Angry Birds’ standings after Rovio closes – as they surely will – this security hole.The full top 12, as of this morning, is as follows:Angry Birds Chopper 2 iPhoto (Apple)iRingtones AperturePinball HDFlight Control HD iMovie (Apple)iHomeworkThe IncidentPixelmatorPagesFree Apps Top Reasons to Go With Managed WordPress Hosting Tags:#Apple#news#NYT#web 8 Best WordPress Hosting Solutions on the Marketlast_img read more
