It’s a Long (Roundabout) Way from Amphioxus

first_img“Every solution breeds new problems” laments a Murphyism, and Henry Gee feels the pain.  In Nature this week,1 he delved into the growing quandary about where to put the common ancestor of starfish, sea squirts and chordates, including the vertebrates and us human beings.  His challenge is to prove the idiot’s sanity:So, if lancelets really are close relatives of echinoderms, what are the implications for our picture of deuterostome evolution?  The short answer is that the textbook scheme is turned on its head.  Rather than the steady acquisition of progressively more chordate-like (and, by implication, human-like) features from an ancestor with nothing much to recommend it, the story becomes one of persistent loss.  The last common ancestor of extant deuterostomes would have been a free-living, bilaterally symmetrical creature with a distinct throat region perforated by gill slits, segmented body-wall musculature and possibly a reasonably sophisticated brain and central nervous system.  In a sentence, the ancestor would have looked like a cross between an amphioxus and a larger, brainier, tunicate tadpole larva.  Crazy? Possibly. But possibly not. (Emphasis added in all quotes.)Reporting on phylogenetic study by Delsuc et al. from fossils and genetics in the same issue,2 the senior editor at Nature tried to be upbeat about the latest proposal, but called it another exercise in humility.  “Time and again,” he preached, “further work has exposed our prejudices for the parochial conceits that they are.” A quote from the paper by Delsuc et al. shares this view, and demonstrates the revolutionary nature of the proposed new phylogeny:The monophyly of Olfactores invalidates the traditional textbook representation of chordate, and even deuterostome, evolution as a steady increase towards complexity culminating in the highly specialized brain of vertebrates.  This anthropocentric interpretation is perhaps best reflected by the terms ‘Euchordata’ (that is, ‘true chordates’) or ‘chordates with a brain’, which are used to designate the grouping of cephalochordates and vertebrates.  Tunicates should therefore no longer be considered as ‘primitive’ but rather as derived chordates with highly specialized lifestyles and developmental modes.    Meanwhile, over in Science Now, Elizabeth Pennisi quoted some other evolutionists not quite ready to accept the new phylogenetic tree.  Calling the tunicate an “ugly sister,” Pennisi quoted experts saying the proposal will turn some heads, and the jury is still out.  She said they said, “Tunicates and larvaceans evolve rapidly and have gained and lost so many genes that it’s very hard to position them properly in an evolutionary tree.”1Henry Gee, “Evolution: Careful with that amphioxus,” Nature 439, 923-924 (23 February 2006) | doi:10.1038/439923a.2Delsuc et al., “Tunicates and not cephalochordates are the closest living relatives of vertebrates,” Nature 439, 965-968 (23 February 2006) | doi:10.1038/nature04336.Evolutionists could use a lot more humility.  They should quit the parochial school of Pope Charlie that is producing a class of lemmings who cling to crazy ideas.  What Gee is saying contradicts evolution.  This new story line puts the advanced muscles, nervous system and mobility of Amphioxus before organisms that were assumed more primitive (in the old “progressive” evolution picture), and describes subsequent evolution as a story of persistent loss.    Meanwhile, Eugenie Scott and Alan Gishlick sit on a Grand Canyon beach trying to whoop up enthusiasm for their evening song service: “It’s a long way from amphioxus / It’s a long way to us. / It’s a long way from amphioxus to the meanest human cuss. / Goodbye fins and gill slits / Hello lungs and hair! / It’s a long, long way from amphioxus, / But we come from there” (10/06/2005 commentary).  It’s even longer when you’re going backwards.  Gee’s story gives them more food for cuss.(Visited 17 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_img21 January 2008The Philippines, second in the 2005 Women’s World Cup of Golf, made a single but massive step forward in the 2008 edition of the event at Sun City on Sunday when they held off South Korea to win the title by two strokes.The two countries entered the final round tied for the lead but, after the Koreans had moved one ahead after 14 holes, the Philippines finished strongly, ending on 18-under-par 198, with South Korea completing the competition on 16-under 200.Dorothy Delasin, playing alongside Jennifer Rosales, was outstanding under pressure; she birdied the final four holes to lift the pair to a final round of seven-under-par 65 in the final day’s betterball competition.Shredded the courseThe South Koreans excelled on the opening day, also played in the betterball format, shredding the normally unforgiving Gary Player Country Club course with a superb 11-under-par 61 to lead by one shot from France, three from Canada, and four from the Philippines, pre-tournament favourites Sweden, and the USA.Hosts South Africa managed a four-under-par 68, leaving the pair of Ashleigh Simon and Laurette Maritz tied for thirteenth, seven shots off the pace.The second day featured foursomes and the Philippines made their move up the leaderboard by posting a four-under-par 68, the best round of the day.Taiwan carded a three-under 69, with Wales the only other nation to finish under par, with a one-under 71. South Africa was one of three teams to go around in level-par 72, along with South Korea and Japan.Triple-bogeyThe Koreans were cruising along, heading for another sub-par round when it all went wrong for them on the 17th as they carded a nasty triple-bogey, thus allowing the Philippines to move up to challenge for the title.The fancied Swedes and Americans struggled and both tumbled down the standings as they limped around the course with rounds of 76 and 77 respectively.Heading into the final day, it was the Philippines and South Korea in the lead on 11-under-par 133, followed by Taiwan, two shots back. Canada, after a round of one-over 73 was alone in fourth on seven-under 137, followed by France, Wales, and Japan on six-under. Home favourites’ South Africa were on four-under-par 140.While the Philippines finished in style to capture the title, the Japanese matched their effort with a final round of 65 to make up three shots on Taiwan and tie for third on 13-under-par 203.Excellent South African effortSouth Africa turned in the third best effort of the day with a six-under 66 which propelled the hosts into a share of sixth, along with Canada and Wales, on 10-under-par 206. France sneaked in ahead of the trio by one shot after posting a five-under 65.It was an encouraging showing by the home country as Simon and Maritz achieved their best finish yet in the tournament.

What is 2017’s top wireless router with the fastest speeds?

first_imgRelated Posts It seems like every day lately, router manufacturers are coming up with some new buzzword or marketing term to sell you on why their networking appliance is better than the rest, without actually having the real performance to back it up. That’s why we’ve teamed up with Gadget Review to extensively test and review the best wireless routers on shelves today, in order to give you a detailed breakdown of everything you need to know about the best wireless routers of 2017.How we choose and why you should buysTo create this year’s roundup of the best routers on the market, we’ve run dozens of newer and some not-so-new models through the ringer to find the best of the best. Using a 1GB symmetrical fiber optic line, we pushed our top picks to the absolute limits of what routers could do, testing on a variety of devices including desktops, laptops, smartphones and tablets. See also: Are prices driving away smart home tech consumers?To make this list, the routers we tested needed to have a minimum wireless bandwidth rating of 1900AC, have at least four ethernet ports on the back, one USB port for media server options, and be able to transmit on both the 2.4GHz and 5GHz spectrum. All the routers here hit the spec of transmitting at 250Mbps or more on 5GHz, and were able to maintain a rate of 300Mbps over a hard-wired connection. Features like software and configuration options were also thoroughly tested, in order to find the best mix of performance, reliability, and price in the best wireless routers of 2017.Our best wireless routers for 2017, compared#1 Pick: Linksys WRT3200ACM Smart Wi-Fi Router – Editor’s Choice/Best Home RouterThe Linksys WRT3200ACM may look old-school on the outside, but it’s all future tech under the hoodPrice: $249.99The Linksys WRT3200ACM may look on the outside like it’s a blast from the past, but after running it through the ringer on everything from downloads to streaming, we can tell you this router might as well be straight out of five years from the future. The WRT3200ACM comes equipped with the latest in bleeding-edge features like MU-MIMO beamforming capabilities and the option to create a mesh network with Linksys’ USB dongle architecture. It also runs all of this on top of Linksys’ revolutionary Smart WiFi dashboard system, which makes it easier than ever to customize and control how your router handles traffic from family members or guests on the fly. If you’re looking for the total package when it comes to performance and power, the Linksys WRT3200ACM is undoubtedly the best wireless router for 2017. #2 Pick: TP-Link Archer C9 AC1900 Wireless AC Gigabit Router – Best Budget Wireless RouterTP-Link Archer C9 wireless router is budget speed at its bestPrice: $119.95As great as the Linksys WRT3200ACM is, though, not everyone out there has a spare $250 laying around to spend on a single router. Enter the TP-Link Archer C9, a smaller, unassuming router that still manages to pump out performance that’s on-par with routers two to three times the cost. In our testing on a fiber line, the Archer C9 was able to push nearly 300Mbps of download speed and almost half a gigabit of upload from 30ft away. If you live in a larger house you may notice a few issues with signal reliability over longer distances, but otherwise the TP-Link Archer C9 is the perfect pick for apartment dwellers or small homeowners who need serious performance on a budget.#3 Pick: Netgear Nighthawk X6 AC3200 Tri-Band WiFi Router – Best Wireless AC RouterNetgear Nighthawk X6 AC3200 Tri-Band WiFi Router does it all and then somePrice: $255Last up on this year’s list we have the Netgear Nighthawk X6, a powerful, imposing-looking router with a rich feature set for the ultra-geek in all of us. As far as customization and configuration goes the X6 is simply unmatched in its category, thanks to the help of Netgear’s newly refreshed online dashboard. Its six high-powered antennas ensure coverage throughout every corner of homes large and small, and although it has a bigger footprint than most, this is the kind of kit you buy if you want your house guests to know you take your home networking more seriously than most. And which wireless router of 2017 is right for you?So, which one is the best wireless router for 2017?They all are, or could be. The best part about routers is that in this category, there’s something that’s just right for everyone. If you want a router that’s got an extensive number of available features like parental controls and QoS management, the Linksys WRT3200ACM is the one for the job. If you don’t have a spare arm and a leg to spend on a router but still want speed, the TP-Link Archer C9 is the perfect budget pick, while beasts like the Netgear Nighthawk X6 are all about range, performance, and reliability in one complete (and very scary-looking) package.No matter what you’re looking for, there’s a best wireless router in 2017 for you!
