More on Winston Ewert’s “Dependency Graph of Life” — An Important New Paper

first_imgSeveral articles at Evolution News have explained the significance of Winston Ewert’s important new BIO-Complexity article. I would like to contribute one more. This one is very short and simple but attempts to give a broader overview of the paper’s significance.Since 1985 I have been arguing that the evolution of life looks much like the evolution of software and other human technology. My main argument, for example in a 2000 Mathematical Intelligencer article, pointed to the fact that according to the fossil record, major new features (new orders, classes, and phyla) appear abruptly, just as major new features in the development of, for example, my PDE solver, appear abruptly, and for the same reason. You only have to think about what gradual development of new organs, or new systems of organs, would look like, or what the gradual development of major new software features would look like, to understand why they must appear abruptly: intermediate stages would usually have to involve incipient new, but not yet useful, features.Evolution of Life, and of SoftwareMore recently I have called attention to another way in which the evolution of life mimics the evolution of software or other human technology. (For example, in the last segment of this video, or in “I Believe in the Evolution of Life and the Evolution of Automobiles.”) In both cases, similar new features frequently arise independently in distant branches of the “evolutionary tree.” This is called “convergence.” For example, when Ford automobiles and Boeing jets evolve similar new GPS systems, or when bats and whales develop sonar echolocation independently, they are converging and becoming more alike, at least in one attribute, rather than diverging and becoming more distinct. My video notes that the basic types of carnivorous plant traps each evolved multiple times independently.This phenomenon of convergence is so ubiquitous that it has become a major problem for evolutionists. As Cornelius Hunter points out in “The Real Problem with Convergence,” the problem is not only that it is hard to believe that very different species would develop similar new features independently: anyone who is able to believe that eyes developed though random processes once will find a way to believe they developed multiple times by chance, as Hunter says. The problem is it destroys the tree of life! Contrary to what the textbooks tell us, the similarities among species do not really point to a strict tree structure of common descent. They look more like the way a designer creates new software or technology products: a designer is free to reuse software modules or pieces of engineering technology from multiple previous products, not just from direct “ancestors” of the new product. New species and new products do, nevertheless, often inherit much of their “technology” from one ancestor.Not the Best Explanation?Winston Ewert has now provided evidence in a quantitative and objective way, by examining several publicly available protein data sets, that a tree of life may not be the best explanation for the similarities between species. Instead, a dependency graph, like that used to document the dependencies of new software products on modules in earlier products, thus explaining the similarities between these products, appears to be a much better model for the similarities between species.  Further work is needed to confirm his results.The bottom line is: the pattern of similarities between species looks more like that arising when intelligent humans develop software or other technologies, and less like that expected to arise from Darwin’s tree of descent with modification. And we have not even mentioned the strongest and most obvious connection between the evolution of computer programs and the evolution of the DNA code in living things. That is the absurdity of attributing the information contained in either to anything other than an intelligent programmer!Editor’s note: For more on Winston Ewert’s paper, see:“BIO-Complexity Presents Better Model than Common Ancestry for Explaining Pattern of Nature”“New Paper by Winston Ewert Demonstrates Superiority of Design Model”“The Dependency Graph Hypothesis — How It Is Inferred”“Response to a Critic: But What About Undirected Graphs?”“Of Species and Software: What Is a Dependency Graph?”Photo: California pitcher plant (Darlingtonia californica), a carnivorous plant, by Noah Elhardt, via Wikimedia Commons.

Sinatra The Musical, Based on Life & Career of Frank Sinatra, in Development for 2020 Debut

first_img View Comments Frank Sinatra(Photo: Frank Sinatra Enterprises) Frank Sinatra Enterprises has announced the development of Sinatra The Musical, a new Frank Sinatra bio-show featuring the music of the legendary singer and actor. Emmy winner Danny Strong (Empire, Game Change), who is also at work on a movie remake of Oliver!, has been enlisted to write a book for the Sinatra musical, which is aiming to hit the stage in early 2020.”It is an honor to get to write a musical about one of the biggest icons of the twentieth century,” said Strong. “Sinatra is one of the great talents of all time and his fascinating and powerful story will make for a terrific stage musical. I’m deeply honored to get this opportunity.”Throughout his nine-decade career, Frank Sinatra performed on more than 1,400 recordings. He received nine Grammy Awards as well as three Academy Awards and three Golden Globes. Sinatra also appeared in more than 60 films, including the 1957 film adaptation of Pal Joey, and produced eight motion pictures. The many songs for which Sinatra is known include “My Way,” “Fly Me to the Moon,” “You Make Me Feel So Young,” “The Lady Is a Tramp” and the iconic anthem “New York, New York.”Sinatra appeared on the Broadway stage in 1975 during the 16-performance concert engagement Frank Sinatra, Ella Fitzgerald and Count Basie. The 2010 balletic musical Come Fly Away featured Tony-nominated choreography by Twyla Tharp danced to the soundtrack of Sinatra classics.Further information about Sinatra The Musical, including debut venue, dates and casting, will be announced at a later time.last_img read more

Amtrak plans to serve Long Island as Metro-North seeks Penn access

first_imgUSA: Amtrak announced on February 5 that it had reached agreement with the New York Metropolitan Transportation Authority covering two enhancements to passenger services. The first is a long-standing proposal to allow MTA Metro-North to use Amtrak infrastructure to reach Penn Station in Manhattan, while the second envisages investment to enable Amtrak inter-city trains to serve Long Island. The Penn Station Access programme would see Metro-North trains use some of the spare capacity that is to be freed up in 2023 when Long Island Rail Road trains are diverted to serve the deep-level terminus at Grand Central Terminal under the much-delayed $11bn East Side Access scheme. Metro-North currently uses the capacity constrained upper platforms at GCT as its Manhattan hub, but PSA would allow the operator to share Amtrak-owned infrastructure between New Rochelle and Sunnyside Yard. The so-called Hell Gate line passes through residential districts in the Bronx, and four new stations are proposed at Hunts Point, Parkchester, Morris Park and Co-op City. The PSA agreement will see MTA fund a programme of enhancements along the Hell Gate line, including signalling, track and power supply renewal; MTA will also share the costs of operation and maintenance of the upgraded route with Amtrak. Amtrak and MTA have also agreed to start planning how inter-city trains could reach destinations on Long Island that are currently only served by LIRR. An Amtrak spokesman told Railway Gazette that ‘no specific’ details of this plan were yet available, but one immediate challenge would be to manage the transition between the third-rail electrification used on LIRR and the mix of overhead AC supply and diesel traction used by Amtrak. ‘We are pleased to have reached an agreement that will allow MTA to advance with design and construction of improvements related to the Penn Station Access project, the eventual operation of new Metro-North commuter rail service into New York Penn Station and construction of four new commuter rail stations in the Bronx’, said Amtrak’s Senior Executive Vice President Stephen Gardner. ‘We are also looking forward to working together on advancing direct Amtrak service to and from key population centres on Long Island.’last_img read more
