Beak Careful: Variation May Be Non-Darwinian

Finch beaks loom large in classical Darwinian theory, but two examples of mouth parts in very different animals show that dramatic variations can be achieved quickly without the slow and gradual accumulation of small changes Darwin envisaged.

From Toxin to Medicine

Botulinum toxin (botox) is now big business in health and fashion, but few may remember it derives from one of the deadliest substances known in nature. Other examples show that some forms of "natural evil" can be seen in a different light.

Follow the Leader: Plants and Animals

Need solutions to engineering problems? Look no further than the plants and animals around you. That's what more and more scientists are doing.

Coelacanth: Survival of the Dullest

A new fossil species of coelacanth was discovered in Canada. Scientists think from its tail fin shape that it was a fast swimmer–perhaps a hunter. Sadly, it was a "spectacular failure" in evolution. The luck of the evolutionary draw went to today's slow-moving, docile species.

Cambrian Explosion: Sedimentary, My Dear Flotsam

"Then something happened." Question: are you reading a science article, or a fictional screenplay? Are you in the Science Department or the Humanities Department? Are you in the lab or the theater? Find out in today's episode of "Explain the Cambrian Explosion."

Fish Came from the Land

If you were taught fish evolved in the ocean, think again. There's a new idea that most fish evolved on land.

Mouse to Elephant? Just Add Time

How do you evolve a mouse into an elephant? Just add 24 million generations. But you can shrink it back down in just 100,000 generations. This and other eyebrow-raising stories have been told in the secular science media recently.

Turning an Unevolved Horseshoe Crab Into a Darwin Showpiece

Horseshoe crabs are survivors by anyone’s measure; they have carried on their lives virtually unchanged, according to the standard evolutionary timeline, for 450 million years. This not only points to incredible stasis against alleged forces of evolution; it also means they have survived at least three global extinctions that evolutionary biologists and geologists say wiped out most other species. Not only that, the world has changed drastically since they allegedly evolved from who-knows-what arthropod ancestors – perhaps trilobites, that appeared in the Cambrian Explosion without ancestors. But the numerous, successful trilobites did not survive the global extinctions. Given these contradictory facts, how can the horseshoe crab possibly be an exhibit for evolution? A recent article shows how.

Living Surprises, Living Hopes

Here are ten recent discoveries about plants and animals that are surprising and inspiring. Some of them may lead to technologies that can improve our own lives.

More Evidence Cambrian Explosion was Un-Darwinian

The Cambrian Explosion (the abrupt appearance of animal phyla in the earliest fossil layers bearing multicellular body plans) remains unmuffled. Known by Darwin as a problem for his theory, it has become more problematic to his followers over time. There are now many more Cambrian fossils than Darwin knew of, and they continue the pattern: sudden appearance of complex animals, complete with legs, digestive systems, eyes, and nervous systems. Discoveries of Precambrian fossils have not helped: the ones that are more than microbial appear to be mere colonies of cells with no relationship to animals. Here are more discoveries that fit this pattern.

Darwinian Explanations: Show or Snow?

We all know the proverbial “snow job.” That’s putting on an entertaining song and dance without doing the assignment. A college sophomore (wise fool) writes a 15-page term paper full of jargon that, on closer inspection, didn’t follow directions or didn’t answer the question – it reveals ignorance of the subject. A job applicant makes an impression with humor or appearance without demonstrating ability to do the work. A junior makes up a fanciful story to cover up why he didn’t mow the lawn. Scientists are supposed to explain things based on observation and testable hypotheses. If Darwinians really believe that an unguided, impersonal, purposeless mechanism led to the diversity of life on Earth, they need to show the evidence. Here are a few recent examples of evolutionary explanations. Check whether they “show” evolution, or distract attention with a “snow” job.

What Do Scientists Know About Prehistory?

Evolutionary biologists and geologists speak of events happening millions or billions of years ago as concrete facts. They are not observational facts, though; they are inferences from indirect evidence. Indirect evidence can often lead to different conclusions; in fact, some philosophers like Duhem and Quine argue for “under-determination of theory by data,” meaning that data can never converge to support just one theory. Some can demonstrate logically that there are an infinite number of theories that can explain a set of data. Evolutionary scientists counter that there are only one or a few that are reasonable (implying that theirs is among the limited set of reasonable ones). Recent discoveries that threaten to overturn past reasonable theories, though, cast doubt on their confidence.

Cambrian Explosion Louder Still

Darwin started a tradition of worrying about the Cambrian Explosion. Over time the problem has only worsened; now we know that all the animal phyla appeared suddenly in the oldest strata containing metazoan (multi-celled) animals. In recent decades, evolutionists had hoped that the strange Ediacaran fossils would provide the needed missing links. In addition, some thought they had found embryos of early metazoans in the exceptionally-preserved Precambrian beds of China. Those hopes have now been dashed, leading to moans and groans from Darwinians.

Human Variability Can Be Rapid

All living humans are interfertile – one species by definition. People from all parts of the globe can marry and have children, even though global travel is relatively recent in human history. Yet we know there is considerable variability between tribes and nationalities. Does this variability take millions of years? Does it lead to the origin of new human species? Recent evidence shows that variations can be rapid, both genetic and acquired, without reducing interfertility.

Hopping Fish and Other Darwin Mysteries

The chieftans of evolutionary theory insist that their doctrines have come a long way since Darwin. Discoveries in molecular biology, population genetics, biogeography, paleontology have left the Victorian concepts of evolution outdated and antiquated, they would say. Yet a look at the evolutionary literature shows otherwise. Simplistic just-so stories, Darwinian phrases like “survival of the fittest” and “missing link,” iconic fossils, and antiquated principles continue to be the rule, as the following articles illustrate.
