Is a Hippo a Pig or a Whale?

March 24, 2009

Two teams of evolutionists are having a spat over whale evolution. Thewissen and team (Northeastern Ohio U) say the hippo is close to the pig, but Jessica Theodor (U of Calgary) and Jonathan Geisler (Georgia Southern U) say it’s in the whale family tree. Their arguments and counter-arguments were published in Nature last week.1 Science […]

Whoops, the Wrong Star Exploded

March 23, 2009

“Our understanding of the evolution of massive stars before their final explosions as supernovae is incomplete, from both an observational and a theoretical standpoint.” That’s how a paper in Nature begins.1 Avishay Gal-Yam was not kidding; a star exploded that theory says was not supposed to. The famous supernova 1987A was already an […]

Evolution of Photosynthesis: A Theory in Crisis

March 23, 2009

“Although the last word on the origins of oxygen-making photosynthesis isn’t in,” writes Mitch Leslie in Science,1 “researchers say they are making progress. One thing is for certain, however: Without this innovation, Earth would look a lot like Mars.” That’s the end of his story. What did he say in the beginning and middle? Not […]

Crystal Mysticism Invades Astrobiology

March 20, 2009

Mystical ideas about the life-giving power of crystals usually go with New Age movies and storefronts. Science is above all that, right? Then what is a reader supposed to think of this opening line by Leslie Mullen on Space.com? One of the greatest mysteries about the origin of life is how the necessary ingredients consistently […]

Amazing Fossils: Do They Help Darwin?

March 19, 2009

Some remarkable fossils have been found recently. According to the reports, scientists are not sure what to make of them, even though evolutionary language is liberally applied to the interpretation. Octopus: The earliest fossil octopus is 100% octopus. A rare well-preserved octopus fossil, as unlikely as finding a fossilized sneeze according to Live Science, shows […]

Physicists Bow to Darwin

March 18, 2009

What’s Darwin got to do with physics? Presumably, if you dropped his statue off the leaning tower of Pisa, it would fall at 32 feet per second squared, but the man is remembered for his speculations about biology, not physics. Why, then, did Nature Physics devote a special issue to Darwin? Here’s what it presented. […]

From Dust to St. Patrick in 5 Billion Years Flat

March 17, 2009

Biblical creationists and evolutionists have one belief in common: we came originally from dust. How that dust became organized is the difference. Both views teach that our bodies are comprised of the same atoms found in dust, but creationists say an intelligent designer purposefully molded the dust into a fully-formed man and woman, whereas evolutionists […]

Peking Man Ages 200,000 Years

March 16, 2009

Dates for Chinese fossils of Homo erectus have been pushed back 200,000 years to 780,000 years before the present, reported Live Science. The report is based on a paper in Nature by scientists who used cosmogenic nuclide dating methods for the first time.1 Ciochon and Bettis, in the same issue of Nature,2 said the report […]

Shedding Light on the Protein Big Bang Theory

March 13, 2009

The precise three-dimensional structure of a typical protein molecule is so complex, its origin would seem hopeless by chance. What if evolutionary biologists were to discover a whole host of proteins literally exploded into existence at the beginning of complex life? We can find out what they would think by looking at an article on […]

More Functional Non-Coding DNA Found

March 12, 2009

Another finding undermines the concept of “junk DNA.” A team of scientists in Massachusetts found over a thousand functional RNA transcripts from intergenic sequences. These RNA transcripts, coming not from genes but from regions earlier thought to be non-functional, take part in diverse functions from stem cell pluripotency to HOX gene developmental processes to cell […]

Scientists Crave Integrity: Can They Evolve It?

March 12, 2009

An important item not found on lab shelves or test tubes has been appearing in science news stories recently: integrity. That’s a word about character: moral rectitude, honesty, accountability, uprightness, the ability to resist temptation. It’s the kind of word one might hear in a sermon. For those who follow Darwin, how did integrity evolve? […]

See Like a Bee, Fly Like a Fly

March 11, 2009

An aerospace engineer in Australia was inspired by insects to design a better way for missiles to find their targets. Aviation Week reported on work announced by the Australian Government Department of Defense. “Bioseeker,” a new guidance system for smarter weapons, was inspired by insect navigation. The Hon. Warren Snowdon, on his website as Minister […]

Ye Are the Salt of the Evolution

March 11, 2009

Salt is good, the good book says (Mark 9:50). Another good thing it may do for you, according to Science Daily, is act as “Nature’s Antidepressant.” Presumably it’s hard to have a good mood about a steak with no salt on it. In the midst of this article about the mood-enhancing effects of salt, an […]

Gobekli Tepe: What Mean These Ancient Stones?

March 10, 2009

Imagine stone carvings and monuments whose age make the pyramids and Stonehenge look like artifacts of modern history. Such monuments exist on a hill in Turkey at a site called Gobekli Tepe. Squared-off limestone blocks stacked like the letter T, arranged in circles, with ornate animal carvings on them, have been baffling archaeologists for the […]

Permian Extinction: The Origin of Specious Geological Events

March 9, 2009

The Permian extinction – one of the most dramatic events in the history of life on Earth, in which some 90% of species went extinct – lay people assume scientists can back up this story with evidence from geology and fossils, but where is it? Whatever happened at the prime site in South Africa, from […]
