    Given its huge success in describing the natural world for the past 150 years, the theory of evolution is remarkably misunderstood. In a recent episode of the Australian series of "I'm a Celebrity Get Me Out of Here", former cricket star Shane Warne questioned the theory - asking "if humans evolved from monkeys, why haven't today's monkeys evolved"? Similarly, a head teacher from a primary school in the UK recently stated that evolution is a theory rather than a fact. This is despite the fact that children in the UK start learning about evolution in Year 6 (ten to 11-year-olds),...
  • Genes of brain-eating tribe members shine light on prion protection

    In the late 1950s, some 2 percent of the Fore tribe from Papa New Guinea died each year from a rare neural disease known as kuru. The mad cow-like disease was spread by the tribe's now-retired practice of eating the brains of their deceased relatives. A new study, however, has identified a gene adaptation that protected a small subset of the Fore population from kuru and other similar diseases. Kuru and other similar diseases are characterized by the proliferation of misshapen neural proteins called prions. These invaders stick together in infected brains, forming plaque-like polymers that slowly suffocate neural pathways...

    Natural Selection Led To Different Features In Europeans As Recent As 5,000 Years Ago, According To Researchers Posted by: Mike Nace March 13, 2014 An increasing volume of archaeological research and effort has come to focus particularly on the genetic evolution and development of human beings since the last Ice Age. While the last glacial period ended about 10,000 years ago, promising, new research suggests that substantial evolution of the human species can now be evidenced even in peoples from as recently as 5,000 years ago — a relative blink of an eye in geological terms — thanks to cutting-edge...

    What makes for a beautiful visage, and why, may have been discovered accidentally on a Russian fur farm BEAUTY, the saying has it, is only skin deep. Not true. Skin is important (the cosmetics industry proves that). But so is what lies under it. In particular, the shape of people’s faces, determined by their bone structure, contributes enormously to how beautiful they are. And, since the ultimate point of beauty is to signal who is a good prospect as a mate, what makes a face beautiful is not only an aesthetic matter but also a biological one. How those bone...

    Researchers scanning the genomes of African-Americans say they see evidence of natural selection as their ancestors adapted to the harsh conditions of their new environment in America. The scientists, led by Li Jin of the Chinese Academy of Sciences in Shanghai, report in the journal Genome Research that certain disease-causing variant genes became more common in African-Americans after their ancestors reached American shores — perhaps because they conferred greater, offsetting benefits. Other gene variants have become less common, the researchers say, like the gene for sickle cell hemoglobin, which in its more common single-dose form protects against malaria. The Shanghai...

The Washington Times reported: President Obama signaled Congress this week that he is prepared to share U.S. missile defense secrets with Russia. In the president’s signing statement issued Saturday in passing into law the fiscal 2012 defense authorization bill, Mr. Obama said restrictions aimed at protecting top-secret technical data on U.S. Standard Missile-3 velocity burnout parameters might impinge on his constitutional foreign policy authority. As first disclosed in this space several weeks ago, U.S. officials are planning to provide Moscow with the...

    Darwin's Sacred Imposter: The Illusion That Natural Selection Operates on Organisms by Randy J. Guliuzza, P.E., M.D. * "Suppose in July 1969 two men watched the Saturn V rocket launch the Apollo 11 mission to the moon. One marveled at the power of nature’s cosmic siphon acting on the rocket to lift it off the pad and accelerate it upward. The other said that liftoff was actually caused by a natural phenomenon called “natural projection” that was inevitable if compressed combustible fuels were released and ignited in a cone, directing violently expanding gases downward with sufficient thrust to lift the...

    Paul Thagard1 and Scott Findlay1 Philosophy Department, University of Waterloo, Waterloo, ON, N2L 3G1, Canada Published online: 20 August 2009 Abstract Darwin’s theory of evolution by natural selection is central to modern biology, but is resisted by many people. This paper discusses the major psychological obstacles to accepting Darwin’s theory. Cognitive obstacles to adopting evolution by natural selection include conceptual difficulties, methodological issues, and coherence problems that derive from the intuitiveness of alternative theories. The main emotional obstacles to accepting evolution are its apparent conflict with valued beliefs about God, souls, and morality. We draw on the philosophy of science...

    San Antonio - A 29 year old man is in custody in connection with the shooting death of a teenager near Jefferson high school overnight, 1200 WOAI news reports. Police think the victim was shot 'accidentally' by a fellow gang member in a home in the 200 block of Thomas Jefferson. The unidentified teen was pronounced dead at the scene. A couple of hours later, detectives picked up Michael Juarez, 29, and charged him with manslaughter. Detectives say both Juarez and the victim were in the same dorky street gang, and the shooting may have been an 'accident.'

    New species might arise as a result of single rare events, rather than through the gradual accumulation of many small changes over time, according to a study of thousands of species and their evolutionary family trees. This contradicts a widely accepted theory of how speciation occurs: that species are continually changing to keep pace with their environment, and that new species emerge as these changes accrue. Known as the 'Red Queen' hypothesis, it is named after the character in Lewis Carroll's book Through the Looking-Glass, and What Alice Found There who tells a surprised Alice: "Here, you see, it takes...

    ScienceDaily: “Slowing Evolution to Stop Drug Resistance” --snip-- For years, evolutionists have pointed to antibiotic resistance as proof of evolution in action. The argument often amounts to this (in simplified form): the fact that certain organisms grow resistant to certain antibiotics is evidence for the evolutionary idea that all animals must have descended from a single ancestor. Collapsing the argument does make it seem a bit silly, but that’s our point. We certainly don’t want to belittle the very real threat of dangerous organisms becoming immune to the best drugs we now have (though the vast majority of microbes are...

    Not to mince words - the modern synthesis is gone --snip-- "The discovery of pervasive HGT and the overall dynamics of the genetic universe destroys not only the tree of life as we knew it but also another central tenet of the modern synthesis inherited from Darwin, namely gradualism. In a world dominated by HGT, gene duplication, gene loss and such momentous events as endosymbiosis, the idea of evolution being driven primarily by infinitesimal heritable changes in the Darwinian tradition has become untenable." ...

    Journal of Creation ^ | Alex Williams
    Darwin’s theory that species originate via the natural selection of natural variation is correct in principle but wrong in numerous aspects of application. Speciation is not the result of an unlimited naturalistic process but of an intelligently designed system of built-in variation that is limited in scope to switching ON and OFF permutations and combinations of the built-in components. Kirschner and Gerhart’s facilitated variation theory provides enormous potential for rearrangement of the built-in regulatory components but it cannot switch ON components that do not exist. When applied to the grass family, facilitated variation theory can account for the diversification of...

    Oct 16, 2009 — It’s called “a fresh theoretical framework” but it undermines the popular conception of natural selection.  It’s called a “dense and deep work on the foundations of evolutionary biology” but it criticizes as simplistic and false the ideas of Richard Dawkins, one of the most outspoken proponents of natural selection as “the greatest show on earth.”  It produces a new scheme for how natural selection works, but raises more questions than it answers.  What is it?  It’s a new book by Harvard philosopher Peter Godfrey-Smith, Darwinian Populations and Natural Selection (Oxford, 2009), reviewed mostly positively by Jay...

    While driving into work recently, I had a near encounter with a squirrel. I'm sure most of you have had one too. What generally seems to happen is this. The squirrel goes to the edge of the road, and looks around. Then, just when your car gets within range, the squirrel darts in front of you, seemingly trying to see how close it can get to being squished, without actually dying. As an added bonus, sometimes, just as you break, or swerve the other way, it will change course. If you are really lucky, sometimes the critter will zigzag three...

    “Charles Darwin and his followers have shown how all life on the planet evolved from a single source. The mechanism they call evolution by natural selection means competition, extinction and the emergence of new life forms without the need for a director or conductor. The Creator shimmers and vanishes like a mirage.” So says political pundit Andrew Marr, one of the BBC’s most senior journalists, in the first of his three BBC2 programmes celebrating evolution and its legacy during the last century and a half. While there was much to agree with in this thought-provoking series, Marr is careful to...
