Origin of Life Made Easy
August 13, 2011
As anyone knows who has been given directions and told “you can’t miss it,” sounding easy and being easy can be entirely different things. Reporters sometimes make the most difficult step in evolution – the origin of life – look like a cinch through the use of suggestive metaphors, like the commonly-invoked phrase, “building blocks of life.” The directions in their articles usually lead to dead ends at worst, or, at best, baby steps on a long march, most of the route TBD, a TLA (three letter acronym) meaning “to be determined.”
Is a Multiverse Detectable?
August 9, 2011
The idea of a multiverse (an ensemble of universes like our own visible one) has been criticized as unscientific because it would be unobservable, even in principle. Now, however, some theoretical physicists are claiming that bubble universes beyond ours could be detected in the cosmic microwave background radiation – provided they collide with our universe. Does this bring multiverse theory back into the realm of science?
When Science Gets Political
August 7, 2011
The classic view of the scientist as an unbiased observer of nature was shattered with the development of the atomic bomb. Suddenly, it became apparent to the physicists working out the equations of nuclear fission could not absolve themselves completely of responsibility for the political uses of their research. Yet since the days of the French Academy of Sciences in the 17th century, kings and other rulers have called on natural philosophers to inform their decisions. These days, scientific institutions state political opinions at will. Some recent news items show them inserting their opinions beyond what the data alone might indicate.
Clue or Clueless on Plant Evolution
August 1, 2011
An article on The Scientist promised to provide “clues to plant evolution,” but the data seemed like clues to something else – namely, design. The article was about how plant proteins interact with one another – the “interactome” (another word to add to genome and proteome). Did the work actually fulfill evolutionary predictions? Even if they claim it did, did it really?
Brave New Chimeras
July 31, 2011
Tampering with human embryonic stem cells has been at the forefront of ethical debates for a decade. Behind it, though, lurks an even more alarming prospect: the creation of human-animal hybrids. As with embryos, the appeal has been to improve human health. But ethicists ask if there is any benefit worth blurring the line between humans and animals. Pro-chimera advocates admit there is a certain “disgust” factor that could arouse public anxiety, and agree that experimentation would need to be regulated. But who would regulate the regulators, and on what moral grounds?
Earth Uniqueness Up; SETI Down
July 29, 2011
Our earth seems special – maybe because it is. Some astronomers are seriously considering that life might be rare or unique on our rare (or unique) planet. If so, hopes for finding sentient aliens on the celestial radio dial drop accordingly. The 50th anniversary of the first SETI search came, unfortunately for search enthusiasts, came at a time when funding is harder to get.
Archaeopteryx Reclassification Raises Fear of Creationists
July 28, 2011
Archaeopteryx isn’t the first bird. At least, not today. It may be reclassified again, but Xing Xu, the man who brought a panoply of “feathered dinosaurs” to the world’s attention, has announced another Chinese fossil that led him to shuffle the bird evolution tree around, putting Archaeopteryx, an “icon of evolution” since its discovery in1861, onto a branch that includes dinosaur terrors like Deinonychus. At least, today. The backstory behind the shuffling of family trees, an upset that raises questions about everything evolutionists that they knew about the evolution of birds, is political, not scientific. Evolutionists are worried about how creationists are going to “spin” the news.
Weird Evolution Tales
July 27, 2011
Evolutionary theory leads to some fantastic tales. Since evolution is often presumed to be a fact that explains everything in biology, and is itself not subject to testing or doubt, everything in biology must be viewed through an evolutionary lens. This hard-core stance on evolution often leads to assertions and explanations that appear contrived, if not preposterous, to Darwin doubters. Here are some recent examples of weird evolution stories that made it past the logic inspectors simply because evolution is unquestioned.
Water, Water Everywhere in Space
July 23, 2011
The largest mass of water has been found surrounding a black hole in a quasar 12 billion light-years away. Space.com says the cloud harbors “140 trillion times more water than all of Earth’s oceans combined.” The discovery not only that “water has been prevalent in the universe for nearly its entire existence,” but that it “was present only some 1.6 billion years after the beginning of the universe.” Alberto Bolatto, of the University of Maryland, said, "This discovery pushes the detection of water one billion years closer to the Big Bang than any previous find.”

Texas Press Perpetuates ID Myths
July 22, 2011
Some reporters refuse to listen. Advocates of intelligent design (ID) have clarified their definitions, their evidences, and their goals for years now, with numerous books, essays, web articles, papers and lectures, but the secular mainstream press continues to misrepresent their positions, and divert discussion from the issues to red herrings. A vote by the Texas School Board concerning supplementary materials to match science standards offered the latest example. The Associated Press story is filled with talking points and generalities; the Discovery Institute response is detailed and to the point, citing scientific journal references for support. Will intelligent design ever get a fair hearing in the mainstream media?
Evolutionary Psychology Is So 1980
July 19, 2011
Evolutionary psychology, popular in the 1980s, has been criticized by some evolutionists as flawed in its basic assumptions. In practice, evo-psych explanations were often so speculative, they amounted to little more than “evolutionary storytelling,” according to an article on PhysOrg. Popular articles still arise from time to time telling us that our minds evolved to cope with hunting and gathering, not the stresses of modern city life (see for instance, “Evolutionize Your Life” from the 07/14/2011 entry). A team now admits that the foundations of evolutionary psychology were always questionable. But never fear, they say: new evo psych is coming!
Science Can Be Wrong for Decades, Centuries
July 18, 2011
The history of science shows some wrong theories being accepted by leading scholars for long periods of time. Ptolemaic astronomy, unquestioned for over 1200 years, is a prime example. Not all examples are old, though. In modern times as well, scientists are finding that theories unquestioned for decades, even centuries, were wrong. That being so, what confidence can we have that today’s scientific beliefs will stand the test of time for the next decade or century? A recent spate of science articles shows some long-held theories being questioned – others being tossed overboard.
Evolutionary Contradiction As Mental Illness
July 14, 2011
In their efforts to get their theory accepted, have some evolutionists crossed the line into irrationality? It is mentally sound to espouse well-argued points of view, even if controversial. What is marginal is arguing self-contradictory beliefs. Let the reader judge whether any of these ideas from evolutionists make sense.
Plant Patterns Prolong Perplexity
July 11, 2011
Plants perform a wonder that has attracted the admiration of scholars from ancient Egypt, Greece and Rome to modern times: the ability to reproduce mathematically perfect patterns. This ability, called phyllotaxis, can be described mathematically with the Fibonacci Series and the Golden Angle. The beautiful spirals in sunflowers, artichokes, cacti, dandelion heads and other plants continue to fascinate children and adults today, but those are not the only examples. Leaves on a stem can emerge in phyllotactic patterns like a spiral staircase, and depending on the environment, plants can switch patterns at different stages in development. Scientists have learned a lot about the players in the phyllotaxis game, but still do not understand the script. The details of how genes and proteins produce the patterns remain elusive.
Can evolutionary theory explain terrorism?
July 2, 2011
In military strategy, it is vital to know what the enemy is up to. Can evolutionary theory help? An interdisciplinary team at the University of Miami got their heads together and appealed to an evolutionary notion called the “Red Queen” hypothesis, and claimed it provides a “Pattern in Escalations in Insurgent and Terrorist Activity” that is neutral regarding the good guys and the bad guys. It resembles, they argue, how pedators and prey evolve in nature. They offer their model as a way military planners can have the ability “to estimate not only the number of fatalities but how often attacks that result in fatalities will take place.” They applied their pattern prediction to the wars in Iraq and Afghanistan. How robust is this notion, and should evolutionary theory take credit for it?
