July 22, 2006
According to a story posted on Yahoo News, Swedish scientists found intact DNA in a bear tooth claimed to be 400,000 years old.  The team leader remarked, “It is usually hard to find DNA that is older than 100,000 years, and work on fossilized DNA mostly focuses on material that is a few tens of […]

Cambrian Mollusk: Does It Help Animal Evolution Story?
July 13, 2006
A soft-bodied mollusk named Odontogriphus known from the Burgess Shale, placed in the Middle Cambrian, has been described in more detail in Nature.1  If the Middle Cambrian is well after the Cambrian explosion, how can the authors claim this pushes the story of animal evolution far back into the Precambrian, before the explosion?  A reporter […]

Science Reporters Spin Spider Web Data Into Evolutionary Program
June 23, 2006
A spider was found perfectly preserved in amber (fossil tree sap), complete with its web and prey.  It is identical to modern spiders.  Isn’t evolution amazing?     If you just experienced a software crash, there must be something wrong with your BIOS.  All the news media ran that program just fine.  A patch is […]

Cambrian Explosion Precursors, or Drops in the Bucket?
June 18, 2006
Two recent presentations, one in person and one in print, tried to fill in the gap of fossils that led to the explosion of diversity in the Cambrian, known as the Cambrian Explosion (see 04/23/2006 entry). Darwin’s Dilemma Solved?  Dr. J. William Schopf (UCLA), renowned discoverer of Precambrian microfossils, triumphantly announced the solution to “Darwin’s […]

How Can They Call This Duck a Missing Link?
June 16, 2006
The news media are abuzz with the phrase “Missing Link” again.  This time, it’s about a fossilized duck or loon found in Early Cretaceous strata in China, announced in Science.1  The article calls it a “nearly modern” bird with soft-tissue preservation, including webbed feet, wing feathers and downy feathers.  They said it “possesses advanced anatomical […]

Mini-Dinos Found in Marine Sediments
June 10, 2006
Sauropods were not all the lumbering giants we think of; they could be the size of a pet dog (images of Deeno in the Flintstones come to mind).  This came to light from recent discoveries announced in Germany (see BBC News and LiveScience) of adult sauropods smaller than human height, ranging five to 20 feet […]

(Guest article)  CNN reported in an article from Associated Press that scientists have uncovered a small cache of dinosaur bones that contains bones from no other animals, and in their excitement have concluded that this means they must have hunted in packs. One expert called the discovery the first substantial evidence of group living by […]

Fish Forsakes Fins in Favor of Arms
May 6, 2006
A crucial fossil palaeontologists are hailing as a true “missing link” in the evolutionary record has been uncovered in the arctic.  The discovery of a well preserved species of fossil fish bridges the gap between finned fish and their four legged relatives.  This croco-fish creature, documented in Nature,1 named Tiktaalik roseae has joints in its […]

Limbed Snakes Initiate Evolutionary Quandary
May 3, 2006
Researchers have discovered the fossil of a snake with a pelvis and functioning legs in Rio Negro, Argentina.  Sebastian Apesteguía (Argentine Museum of Natural Science) says Najash rionegrina is not the oldest snake discovered; marine snakes have been discovered in North America as well as Eastern Europe.  However, Najash rionegrina has been considered the earliest […]

Walking Snake Bites the Dust
April 24, 2006
It must be missing link season.  MSNBC News announced a snake with rudimentary legs.  While exciting for evolutionary theory, it raises questions, too.  Snakes were supposed to have evolved in the water, not on land. Check out what Ken Ham said on Answers in Genesis about this latest salvo.  If the snake had legs, does […]

Paper View:  Cambrian Explosion Damage Control
April 23, 2006
Like some federal official holding a press conference after a disaster, a Harvard paleontologist has tackled the unenviable job of explaining what Darwin called the most severe challenge that could be levied against his theory: the fossil record. The challenge starts with a bang...

Step Aside, T. Rex: Bigger Dino Found
April 19, 2006
A cache of dinosaur bones, meat-eaters bigger than Tyrannosaurus rex, has been uncovered in South America.  National Geographic News says the new species, Mapusaurus, exceeded the former heavyweight carnivore in size and agility.  All the bones in a river deposit were 100% from this one species, so “the chances they had been deposited randomly are […]

Paleoanthropologists Announce the Middle Man
April 12, 2006
In unison, the news media joined the most recent chorus over alleged fossil human ancestors: “Fossil find improves knowledge of human origins” (Live Science): “Fossils fill gap in human lineage,” (BBC News); “Ancient fossils fill gap in early human evolution” (Yahoo News); “Fossil discovery fills gap in human evolution” (MSNBC News, which adds, ‘We just […]
