Clue or Clueless on Plant Evolution

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

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?

Unique Mammal Senses

The ability to sense the environment is vital to all living things, and is a key characteristic that separates life from non-life. The senses are not limited to the five we learn as children – sight, hearing, touch, taste, and smell. In the animal kingdom there are more. Some of them repurpose existing organs; some detect other information from the world not detectable with the normal sense organs. In mammals, two very different animals – bats and dolphins – have expanded our understanding of sensation.

Archaeopteryx Reclassification Raises Fear of Creationists

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

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.

Dinosaur Protein Is Primordial

Scientists from 10 universities and institutions have verified that the collagen protein in dinosaur bone is primordial – i.e., from the dinosaur, not from later contamination. By first studying the molecular packing of collagen in living animals, and using X-ray diffraction modeling, they matched the surviving collagen molecules to those that would most likely survive degradation. They feel this establishes the authenticity of the protein fragments against claims of contamination and simultaneously offers a mechanism for its resistance to degradation.

Butterfly Swarm Buries Darwin

Billions of butterflies, flashing their gossamer wings with brilliant colors, have swarmed over Darwin, leaving him unable to breathe. Figuratively, that is. Illustra Media’s new documentary Metamorphosis, just released on Blu-Ray last week, leaves little room for Darwin’s theory, while making a powerful case for intelligent design. The film is already being hailed as a masterpiece.

Fossil Finds Feed Facile Fables

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.

Science Can Be Wrong for Decades, Centuries

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.

Plant Patterns Prolong Perplexity

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.

Chewing on Evolutionary Stories

Fish chew by sending their food on an assembly line to the back of the mouth. Mammals chew by positioning food for the teeth. Can evolution explain this difference? Science Daily was sure of it. “Evolution has made its marks -- large and small -- in innumerable patterns of life,” The article said. “New research from Brown University shows chewing has evolved too.” When one looks for the evidence that chewing has evolved, though, one only finds blanks with the assumption that evolution must have done it.

The Evolution of… Come Again?

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

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 […]

Complex Arthropod Eyes Found in Early Cambrian

Complex eyes with modern optics from an unknown arthropod, more complex than trilobite eyes, have been discovered in early Cambrian strata from southern Australia. The exquisitely-preserved imprints of the eyes in shale were reported by Lee et al. in Nature. The abstract started by quoting Darwin and affirming evolution, but then revealed evidence that complex eyes go further back in the fossil record than previously thought possible.

A Tale of Two Pollens

Ambiguity is a bad word in science. Scientists want to be objective. To scientific realists, scientific truth is “out there” in the world, waiting to be discovered. The 20th century tempered scientific realism somewhat from its extreme form (scientism, the belief that science is the only reliable guide to truth). Knowledgeable scientists are more or less aware of the role of paradigms, social pressure and webs of belief that can affect interpretations of scientific data. But there is still a widespread perception that science “finds” truth in the world. Whether that happens can be pondered while exploring two recent stories about fossil pollen that arrived at opposite conclusions: one (by evolutionists) that supports old-earth geology (and “climate change” politics), and one (by creationists) that undermines it, finding fundamental biases among evolutionists who refuse to accept the implications of the data.
