Early Man Was Like Us
September 5, 2011
Human evolution theory has been dealt more body blows this month, raising questions whether it can sustain any more injuries after a decade of repeated punches and concussions. How many times can a theory take the “everything you know is wrong” body slam? We’ve already seen Neanderthals promoted to fully human status. Now, some evolutionists are claiming that the “missing links” on the way to modern humans were all interfertile with us.
Adventures in Biomimetics
September 2, 2011
The imitation of nature in engineering has become one of the hottest trends in science. Almost every week, amazing technologies are being advanced the easy way – by observing how living things do it. We all stand to benefit from the design-based science of biomimetics. Here are a few recent examples.
How the Reporter Evolved Its Silliness
August 23, 2011
When it comes to evolutionary stories, reporters have a knack for propounding the silliest notions about human origins. This tendency is evident in several recent science news stories about early man propounding, with nary a blush, outlandish claims with little evidence – or no evidence whatsoever.
Secularists Lured to Paganism
August 15, 2011
If man is hopelessly religious, what happens when society’s scientific elites teach that religion is groundless? G. K. Chesterton once said, “When people stop believing in God, they don’t believe in nothing — they believe in anything.” The new atheists claim to base their beliefs on scientific evidence. They have no need for religious teachings or rituals. Is it not strange, then, to see the attraction of secularists to movements that give the appearance of new religious forms? Is there something innate in human nature that cries out for the sense of ultimate purpose and connection to the divine that religions have traditionally provided? Three recent examples of near-cult experiences may be illuminating.
Book Review: The Days of Lamech
August 14, 2011
To Biblical creationists, the period before the Flood lasted some 2,000 years – an immense span of time for humans with an explosive mix: high intelligence and a murderous sin nature. Yet the Bible provides few details about this period. How far did civilization proceed? What technologies did they develop? We know from Genesis they lived long, built cities, worked metals, made musical instruments, and mastered farming. We also know that the world was filled with violence. A new novel explores the possibilities of that tantalizing past. Building on the success of his first novel The Days of Peleg, novelist Jon Saboe has just published the long-awaited prequel, a drama set in the height of the antediluvian civilization: The Days of Lamech.
Archaic Humans Are One With Us
August 12, 2011
According to the biological species concept, two varieties of anything are considered one species if they can interbreed and produce fertile offspring. Applied to humans, new evidence suggests that Neanderthals and the recently-discovered Denisovans were members of the human species. According to New Scientist, “On the western fringes of Siberia, the Stone Age Denisova cave has surrendered precious treasure: a toe bone that could shed light on early humans’ promiscuous relations with their hominin cousins.” Since one can only be promiscuous within the same species, this puts enormous pressure on evolutionary timelines that assume the Denisovans split from the Neanderthals 300,000 years ago.
Hobbits Were Brain Diseased Modern Humans
August 8, 2011
The discovery of fossils of miniature humans in Indonesia, designated Homo floresiensis but nicknamed Hobbits, was one of the most exciting and controversial announcements of 2004. Since then, interpretations of the fossils have fallen into two camps: those who think the skeletons represent normal humans with the brain-defective disease microcephaly, and those who think they represent evolutionary missing links. A new paper compared skulls of H. floresiensis with those of modern humans, Homo erectus, and humans with microcephaly. The result favors the interpretation that the Hobbits most likely were diseased modern humans.
Cell Chaperones Keep Proteins Properly Folded
August 2, 2011
Imagine linking together a chain of 300 plastic shapes, some with magnets at various places. Then let it go and see if you could get it to fold spontaneously into a teapot. This is the challenge that cells face every minute: folding long chains of amino acids (polypeptides) into molecular machines and structures for the cell’s numerous tasks required for life. DNA in the nucleus codes for these polypeptides. They are assembled in ribosomes in single-file order. How do they end up in complex folded shapes? Some polypeptides will spontaneously collapse into their native folds, like the magnetic chain in our analogy. Others, however, need help. Fortunately, the cell provides an army of assistants, called chaperones, to monitor, coax, and repair unfolded proteins, to achieve “proteostasis” – a stable, working set of proteins. That army is so well-organized and complex, scientists continue to try to figure out how it performs so well in the field.
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?
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.
Fossil Finds Feed Facile Fables
July 20, 2011
Remarkable fossils continue to come to science’s attention, yielding clues about past ecological conditions. Once in awhile, whole fossil specimens – even graveyards of many organisms – are uncovered, but most fossils are mere fragments. Placing fossils into interpretive stories requires knowledge of other fossils and comparisons with living species. Even then, the history of life is not directly observable. Fossils, being silent, can only show their current state; the lack of access to the past, combined with ignorance of all the clues, leaves room for alternative interpretations. Evolutionists, in their desire to fit fossils into a preconceived story, sometimes go far beyond what the actual fossil evidence is capable of saying – and some of their explanations border on the miraculous.
Body Language Says Design
July 17, 2011
Your body is speaking to scientists. Some of them hear it saying evolution. Others think it says intelligent design. What characteristics would each side expect? Most people intuitively know design when they see it. Here are three recent scientific papers that may help interpret body language.
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?
The Evolution of… Come Again?
July 1, 2011
Science news articles speak freely of the evolution of this or that, but the fine print often shows a disconnect with the evolution explanation. Can one speak of the evolution of something that has not changed for millions or years? The details in the following stories raise questions whether anything significant has evolved in the […]
Cells Have Dimmer Switches
June 30, 2011
A metaphor has been emerging among biophysicists: cells have rheostats or dimmer switches. The metaphor implies that some cellular regulatory processes are not just on or off; they have continuous ranges of values that can be finely tuned for the need of the organism. It's been years since our first report that gene expression is […]
