Giraffe Has Supercharged Heart
November 22, 2009
In many ways, the giraffe has been an icon of evolution.  Why, and how, did it get its long neck?  These questions have often been the focal point of a clash of Darwinian and Lamarckian explanations.  Today, many just assume it evolved somehow.  For instance, BBC News article stated flatly, “A giraffe’s heart has evolved […]

Evolutionary Explanation Is Always a Work in Progress
November 19, 2009
As evolutionary biologists examine diverse plants and animals, it seems they are never able to give a definitive answer as to how they got that way.  Their work merely begins or continues to search for clues.  Like mothers, their work is never done.  At least this provides them job security. Box jellyfish:  There are about […]

How a Biotoxin Evolved
November 2, 2009
What do shrews and lizards have in common?  Not much, but two species developed the same toxin in their digestive enzymes, giving them both a poisonous bite.  Science Daily said a harmless digestive enzyme became overactive through three related changes.  “What had been a mild anticoagulant in the salivary glands of both species has become […]

Beethoven: It All Began With a Thump
October 17, 2009
Live Science in all seriousness, “When monkeys drum, they activate brain networks linked with communication, new findings that suggest a common origin of primate vocal and nonvocal communication systems and shed light on the origins of language and music.”     Choi reported on work at the Max Planck Institute for Biological Cybernetics to determine […]

Fossil Said to Enlighten Evolution of the Ear
October 13, 2009
Did mammal ear bones evolve?  If so, it was not a straightforward Darwinian progression.  Authors of a paper in Science who announced a new Cretaceous mammal fossil from China had to invoke convoluted explanations to keep the evolution story intact. Science Daily shows an artist’s conception of Maotherium, a chipmunk-sized mammal said to have lived […]

Return of the Peppered Mice
August 28, 2009
Slight changes in the coat color of deer mice is the latest triumph of evolutionary theory, if we are to believe the BBC News and New Scientist.   The BBC announced, without apologies to Jonathan Wells, that “A tiny pale deer mouse living on a sand dune in Nebraska looks set to become an icon of […]

Does Evolution Produce Winners?
August 25, 2009
Referees at UCLA are calling the shots in an unusual sport: the evolution game.  Mammals, birds and fish swept the medals.  The losers?  crocodiles, alligators, and a “living fossil” reptile called the tuatara.  According to the judges, the more the biodiversity, the more a group wins points; the more their species go extinct or remain […]

Appendix to The Origin: “Darwin Was Wrong”
August 21, 2009
The appendix, that lowly dollop of tissue relegated to vestigial organ status by the Darwinians, is alive and well with new respect.  Science Daily announced results of the “first-ever study of the appendix through the ages.”  Conclusion: “Charles Darwin was wrong: The appendix is a whole lot more than an evolutionary remnant.  Not only does […]

Evolution of the Knuckle Head
August 12, 2009
An evolutionary anthropologist looked at the knuckles of chimpanzees.  Then she looked at the knuckles of gorillas.  Then she looked at her own knuckles.  Conclusion: humans evolved from tree climbers, not knuckle walkers.  Her theory can be read in Live Science, based on a paper in PNAS.1     Tracy Kivell and Daniel Schmitt from […]

A Rat Race to Build Whiskered Robots
July 11, 2009
Some scientists at Bristol Robotics Lab are pretty proud of themselves for building a robot with whiskers.  It can seek out and identify objects using its whiskers, just like rats do.  But they should still take their hats off to their living model, because the rat’s technology is far superior.  Science Daily mentioned several facts […]

How the Animals Learned to Count
July 6, 2009
Any evolutionary article that begins with “How…” should be checked for Kipling-style just-so storytelling.  Characteristics to watch for include (1) fanciful speculation without evidence: i.e., “made-up” tales that provide an answer to a childish question without appeal to rigorous proof, and (2) statements made with dogmatic authority, like a parent would explain to a child […]

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 […]
