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in molecular biology, population genetics, biogeography, paleontology have left the Victorian concepts of evolution outdated and antiquated, they would say.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.
Early Man Stories Evolve
December 11, 2011
Early man evolved, evolutionary scientists assure us. But it's not clear what is evolving more: our ancestors, or the tales told about them.
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.
Methuselah Seed Now a Tree
December 4, 2011
The world’s oldest viable seed is now a tree 8 feet tall. The Methuselah palm, discovered in the 1960s as a seed at the Judean fortress of Masada, sprouted in 2005 under controlled conditions. It is the oldest seed verified by radiocarbon dating to be 2,000 years old – from the time the Romans were besieging the mountain fortress built by Herod the Great.
Simplest Explanation: Dinosaurs Drowned
November 23, 2011
Why are dinosaur skeletons so often found with head arched backward? The simplest explanation, according to one experimenter, is that they drowned in water.
Fungi Shed Light on Deep Biological Mysteries
November 20, 2011
Fungi are among the least studied and least understood organisms. Elevated from plants to their own kingdom in 1969, they are extremely diverse yet difficult to observe, since many species cannot be grown in the lab. The gaps in our knowledge of the fungi are being filled by new efforts to catalog them, but one of the most interesting findings may come from analysis of their genomes. A new study shows that introns (intragenic regions) are more dynamic than previously thought.
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.
Whale Fossils: Challenge or Support for Evolution?
November 14, 2011
When most fossils consist of small shelly creatures, finding a whale is indeed big news. Two whale fossil discoveries on opposite sides of the world are spectacular and puzzling. Do they support the theory that whales evolved from land mammals?
Selling Confabulation as Science
November 11, 2011
Science is supposed to be all about demonstrable proof through experiment. Should some scientists get away with confabulation – mere storytelling? Look at these recent headlines published on science news sites and consider whether some serious housecleaning is in order.
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.
Your Copper Pipes
November 8, 2011
Each of us is part metal. Our bodies contain iron, copper, zinc, magnesium, manganese, vanadium, molybdenum, selenium, and even nickel like the coins in our pockets or purses. Unlike the other common elements of life (carbon, oxygen, hydrogen, calcium, nitrogen, phosphorus), our metals are not synthesized and recycled, but must be imported and handled with care. Copper is a good example of a biological metal that performs multiple useful functions – that is, unless something goes wrong with the machinery handling it.
Man, Mammals, and Ice Ages
November 7, 2011
What do scientists really know about early man and the creatures in his habitat? Some clues can be found by following science news in a historical fashion: that is, to look for reversals of previously-held opinions, surprises in fossils, and other evidences that scientists are not really making progress in their theories, despite the common […]
