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.

Biomimetics for Your Christmas Wish List

Biomimetics (the imitation of nature) continues to promise cool gadgets and useful materials that will someday yield prized gifts under the tree. Some of them might even save your life.

Cambrian Predator Had Modern Eyes

An exquisite fossil alleged to be 515 million years old shows a compound eye so complex, it looks as good as any modern insect’s eye. The eye belonged to Anomalocaris, the fearsome predator of Cambrian seas, one of the key players in the Cambrian explosion – the sudden appearance of all the animal phyla in the earliest rock layers.

Incredible Small Creatures That Deny Evolution

While the largest of animals impress us with their size and bulk, some of the most amazing are those you could hold in the palm of your hand. Here are three worth appreciating a little more.

Animal Plan: It Works Well

There were Greek and Roman naturalists who were intrigued by what they saw in the living world, but their observational tools were limited to their five senses. Modern science has expanded our senses far beyond the capabilities known just a century ago. We are privileged to live in an age of discovery that is revealing even more wonders beneath the surface of living things, wonders worth knowing about. Here are just a few.

Animal Magnetism and Other Wonders

What is it that so attracts us to animals? Is it animal magnetism? Some animals do have magnetic senses that can guide them across oceans. The more we learn about animals, the more we should admire their high-tech equipment. Here are some recent examples of amazing animals, some of them suitable for Halloween decorations.

Amazing Fossils: What Do They Mean?

Almost every week, on continents around the world, remains of once-living creatures come to light. Here are just a few of the fascinating fossils that have been reported this month. What do they suggest about life in their day?

Biomimetics to the Rescue of Science

The booming field of biomimetics (imitating nature’s designs) is fascinating not only for the amazing products it promises, but for the fresh new opportunities it provides for science and engineering. From viruses to mammals, everything in the living world is now being seen in a new light: agents of innovation that humans can learn from. Here are just a few examples in recent news, arranged in order from large to small inspirational creatures.
