Animals Are Not Malthusians
July 2, 2009
According to Malthus and Darwin, the struggle to survive favors those who have the most fitness to take advantage of limited resources.  A study by the Research Institute of Wildlife Ecology in Vienna, reported by PhysOrg shows this is not the case: Charles Darwin and his contemporaries postulated that food consumption in birds and mammals […]

The Elephant Explosion
June 30, 2009
The title is not intended to suggest pieces of pachyderm flying all over the place, but rather one paleontologist’s theory about the rapid pace of elephant evolution 60 million years ago.  He bases his ideas on a small fossil he found in Morocco.  According to him, the primitive ancestor of all elephants (order Proboscidea) lived […]

Animals Become Tame with Minor Genetic Changes
June 9, 2009
“In what could be a breakthrough in animal breeding, a team of scientists from Germany, Russia and Sweden have discovered a set of genetic regions responsible for animal tameness,” began a report in Science Daily.  Groups of tame rats and aggressive rats were bred separately, then mated.  Scientists identified genetic regions responsible for the different […]

Tickle Me Darwin
June 8, 2009
Observation: orangutans seem to laugh when tickled.  Conclusion: humans evolved laughter from our ape past.  This is the story being promoted by the science news outlets.  “At least 10 million years ago, our ancestors may have been laughing it up over the latest stone-age prank or bout of tickling,” announced Live Science.     New […]

“Social Brain Hypothesis” Discredited
June 4, 2009
According to evolutionary theory, the extra processing required for living in social groups should make brains bigger.  Not so, found a couple of scientists who looked into the question.  There’s no general correlation.     According to Live Science, John Finarelli (University of Michigan) and John Flynn (American Museum of Natural History in New York) […]

Ho-Hum, Another Human Missing Link
May 19, 2009
Shoppers typically are wary of over-hyped ads, knowing that any claim sounding too good to be true probably is.  What would they think about media reports claiming a new fossil monkey is the “8th wonder of the world”?     The scientific paper in PLoS ONE1 had hardly been published before the press went ape, […]

Darwinizing Morality
May 13, 2009
Darwinists continue to try to lay claim to morality (cf. 01/20/2008, 05/02/2008, 03/12/2009)  If Darwinism is to succeed as a comprehensive world view, it must explain this innate sense we all have that certain actions (e.g., torturing babies, slavery, genocide) are morally wrong.  Without a God telling man “Thou shalt not”, how can all humans […]

Missing Links Found: Walking Seal, Teen Tyrannosaur
April 23, 2009
Science news media are abuzz with reports that two missing links have been found.  One is a fossil seal (pinniped) with four legs, the other a smaller presumed ancestor of the famous Tyrannosaurus rex. Seal:  National Geographic News calls it a seal with arms, and features artwork of an otter-like animal doing a kind of […]

Is Darwinism Useful Explaining Cognition?
April 15, 2009
One would think the evolution of mind involves a straightforward account of improving cognition as one progresses up the evolutionary tree.  It’s not so simple, said two researchers in a Nature essay:1  Darwin’s theory of evolution by natural selection is broadly accepted among biologists, but its implications for the study of cognition are far from […]

Animal Flight Control: Where’s the Evolution?
April 12, 2009
A couple of articles in Science last week discussed the marvels of flight control in birds.  “Being earthbound save for the ability to fly airplanes and helicopters, humans stand in awe of animals that power their own movement through the air by flapping their wings, and of the spectacular maneuvers that some of these animals […]

Evolutionary Explanations: Substance, Seasoning, or Storytelling?
April 7, 2009
A scientific theory should explain why certain phenomena in nature are the way they are.  This layman’s view, though simplistic, expects that a theory should also predict new phenomena before they are observed.  In many science reports on evolution, however, one finds evolutionary theory tacked on as an explanation after the fact, when the theory […]

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 […]

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 […]

A Tale of Two Sites: Moby Dog and The Claw
February 6, 2009
Discoveries portrayed as major evolutionary missing links were announced this week.  One is a putative transitional form from land animal to whale, and one is a Cambrian trilobite-like creature said to be evolving the first claw. Moby dog:  The current evolutionary scenario for the origin of whales is that they evolved from dog-like hoofed animals […]

Nature Struts Darwin Gems
January 2, 2009
Like a showcase of pearl-handled revolvers, an armory of evidences Nature calls “Darwin’s Gems” have been exhibited to warn creationists that Darwin Day will be defended next month with a show of force.  The authors, Henry Gee (former editor of Nature), Rory Howlett and Philip Campbell have made their 15 Evolutionary Gems freely available “and […]
