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.

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.

Body Language Says Design

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?

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?

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 […]

Avoid Confusion: Disbelieve Paleoanthropologists

If you care about the true history of the human race, don’t believe paleoanthropologists. They are clueless and confused. Every solution they come up with creates new problems, and their boastful announcements are likely to be overturned. That’s the gist of a commentary in PNAS by Bernard Wood, who wrote, “The origin of our own genus remains frustratingly unclear.” He ought to know; he’s an eminent paleoanthropologist himself.

Follow the Leader: Nature

Ever since biomimetics (the imitation of nature) gradually emerged around 2002 and really took off in 2005, it has not slowed down. Over 90 previous entries in these pages have reported teams all over the world seeking out natural designs for ideas. The reports have accelerated in recent years to the point where there is only space for short summaries that give a taste of the wide variety of engineering work taking inspiration from plants, animals, and even cells. You yourself might inspire some inventor. Here are a few more highlights from recent adventures in biomimetics.

Stem Cell News

Stem cells continue to be hot subjects for research. They are divided into two basic “political” parties: embryonic stem cells (ES), which raise ethical issues about tampering with human life, and adult stem cells (AS), found throughout the body, which have no ethical issues and show the most progress for therapy. The latter include the induced pluripotent stem cells (iPS), coaxed from adult cells to recover the ability to differentiate into multiple tissue types. Even though AS is leading, some scientists are still demanding federal funding for ES.

Inner Ear Hair Cells Overcome Friction

The cochlea, that spiral-shaped structure in the inner ear, is filled with fluid. In this fluid, tiny hair cells called stereocilia are positioned in bundles along the length of the structure. These bundles sense vibrations transmitted into the fluid from the bony levers of the inner ear. The vibrations picked up by the hair cell bundles, each tuned to its own frequency, mechanically transduce the sound impulses by opening ion channels that set up electrical impulses in the auditory nerve, that travel to the brain. But motion in fluid creates friction known as viscous drag. How do the hair cell bundles overcome it? Scientists have figured out that the hair cells in the bundles are not only finely tuned to reduce viscous drag, but actually to employ it for even higher sensitivity to sound.

Evolution Against Intuition

As a general theory of life, evolution promises to explain everything. Not all observations fit neatly into that assumption. How do evolutionists respond when surprising or counter-intuitive observations require integration into the theory? Sometimes the only answer is that they evolved because they evolved. These 10 examples (with encore) can provide case studies for the discerning.

Appreciate Your Gifts

We like to showcase stories of amazing animals, but humans are special, too. What animal can boast some of the qualities that science has recently reported?

The Eyes Have It: Pro Software

You have a biological version of Photoshop in your eyes.  That’s what Richard Robinson, a freelance science writer from Massachusetts, said in PLoS Biology.1  The eye is not a camera, and the retina is not a piece of film.  Indeed, the retina might be better likened to a computer running Photoshop, given the extent of […]

More Complexity in Simplicity Found

Primitive things aren’t.  That seems to be a common thread in some recent stories that found more complexity in simple living things. Box jellyfish eyes:  Jellyfish are among the simplest of animals, so why do box jellyfish have two dozen eyes but no brain?  Some of these eyes have now been found to detect features […]

Seeing Is Believing, or v.v.

What you see is not what is out there in the world – not exactly, at least.  Scientists have shown that your brain is tweaking the light coming in from your eyes and making predictions about what you expect to see.     The “blind spot” experiment is well known to students.  That’s where it […]
