Cambrian Explosion Louder Still
December 23, 2011
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
December 19, 2011
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
December 12, 2011
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in molecular biology, population genetics, biogeography, paleontology have left the Victorian concepts of evolution outdated and antiquated, they would say.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
December 8, 2011
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
December 7, 2011
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
November 19, 2011
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
November 10, 2011
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
October 30, 2011
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?
October 13, 2011
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
October 10, 2011
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.
Mighty Mitochondria Conduct Energy Exquisitely
October 7, 2011
None of us could live without mitochondria. These are the power centers ubiquitous in eukaryotic cells. They contain molecular machines in factories whose jobs are to generate and conduct electrical currents. The currents run turbines that packetize the energy in molecules of ATP, which are then used by most processes in the cell. New discoveries continue to fascinate scientists with how mitochondria work. Some scientists use their energy to find ways Darwinian evolution could build the machinery of life.

All biologists agree – creationists and evolutionists alike – that organisms show remarkable adaptations to their environment. They differ only in their explanations for how they got that way. Here are some remarkable examples of adaptation that will challenge any theory of origins.
Stretching Credibility in Evolutionary Stories
September 20, 2011
Improbable events happening numerous times; selective extinctions; voodoo phylogenetics – at what point do evolutionary explanations exceed the threshold of credibility a trusting public grants to the gurus of the culture, scientists?
Are Biological Clocks Like Paley’s Watch?
September 9, 2011
What is a clock made of? We think of springs, gears and moving parts made out of metal. But a clock could, in theory, be designed with almost any material. There are water clocks, sundials, and electromagnetic oscillators that all function to tell time. What difference does it make if the parts are made of liquids, laser beams, or plastic? What if a clock was made of biological material—would it be any less a device for keeping time? Would it surprise you that such clocks exist in your body and in every living thing?
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.
