When Is a Primate a Human Ancestor?
May 14, 2007
Behold Aegyptopithecus zeuxis, an extinct fossil monkey. It had a brain smaller than a lemon, smaller than that of modern lemurs. Why, then, are the news media touting this as a human ancestor? The new specimen of Aegyptopithecus is more intact and complete than previous specimens. Two surprises were noted; the amount of […]
Fossil Forest Found in Coal
April 23, 2007
A Carboniferous forest extending some 4 square miles has been found in the ceiling of a coal mine, reported Science Daily, Live Science and News@Nature. About 50 species have been identified, including ferns and horsetails over 10 times taller than those alive today. News@Nature remarked that the forest contained some mangrove-like plants. The article quoted […]
Jurassic Park Gets Overhaul
April 17, 2007
How much do we understand the dinosaurs? ABC News reported on some big-time updates and revisions being made to the Carnegie Museum of Natural History dinosaur exhibits. The title of the article is, “Getting Their Dinosaur Facts Right, at Least for Now.” The problem is that even though the newest of the dinosaurs are 65 […]
Proteins Found Preserved in T. rex Bone
April 12, 2007
Preserved fragments of collagen have been found in a dinosaur bone alleged to be 68 million years old. Read all about it in Science Daily. Analysis of soft tissue found by Mary Schweitzer and team turned up the recognizable protein fragments. Protein was also detected in soft tissue from a mastodon said to be half […]
Earliest Comb Jelly Fossil Looks Modern
April 3, 2007
One would think that a paper listed in the category “Evolution” would include supporting evidence that evolution had occurred, but a new Evolution paper in PNAS provides more arguments against it than for it.1 An international team studying early Cambrian fossil beds in China found a comb jelly embryo essentially identical to those alive today. […]
Did Indians See Jurassic Beasts?
March 30, 2007
Did Indians have familiarity with Jurassic monsters, or were they good paleontologists, skilled at reconstructions? In the “Random Samples” page of news tidbits in the journal Science March 30,1 the story is told and the interpretation given: Some fossils are rare, but this one recently unearthed in eastern Oregon may be positively mythic. In life, […]
Leakey Manipulated His Apelike Skull 1470 to
March 27, 2007
The skull of an alleged human ancestor Richard Leakey made famous in 1972 was poorly reconstructed, claims a paleoanthropologist who specializes in craniofacial biology. According to Dr. Timothy Bromage of New York University, Leakey employed nonstandard principles while assembling the bones of his “Skull 1470”, giving the face a flatter, more human-like profile. Many at […]
New Dinos Found; What Do They Mean?
March 27, 2007
There is often a wide gap between the bones that are found and the stories that are told about them. As new dinosaur bones come to light, some reporters cannot resist imagining all kinds of things about their lifestyles. Here are two recent examples. As a bonus, we’ll add a non-dinosaur reptile story or two. […]
Missing Link, or Just Jawboning About Ear Evolution?
March 19, 2007
Tetrapod vertebrates (four-footed animals with backbones) comprise a dizzying array of species, both living and extinct. When is it justifiable to arrange different forms into an ancestral evolutionary sequence, especially when some members are extinct and others are still alive today? On what basis can scientists claim that a discovery demonstrates evolution? Some Chinese scientists […]
Dino Horns: Is Smaller More Evolved?
March 5, 2007
One can never tell which way the evolutionary path will take to determine fitness. Could be bigger, could be smaller. Could be faster, could be slower. Could be better camouflaged, could be flashy. Michael Ryan (Cleveland Museum) decided that shorter horns on his dinosaur constituted better fitness. CNN says his discovery, a 20-foot dinosaur in […]
Fossil Fish Meat Pushes Idea of Early Complexity
February 12, 2007
An article in National Geographic News today has a title to catch the eye (or nose) of seafood lovers: “Fossil Meat Found in 380-Million-Year-Old Fish.” Knowing how quickly fish spoils if left out, this might strike a reader as surprising. Sure enough, fossilized muscle, with “bundles of muscle cells, blood vessels, and nerve cells” clearly […]
First Euro-Stegosaur Found
February 4, 2007
A Stegosaurus fossil has been found in Portugal, reported Live Science. Previously this species with its spiked tail and prominent rows of plates on its back was only known from North America. A tooth, some leg bones and part of the backbone have been unearthed. So far, the fossil looks indistinguishable from its North American […]
Dinosaur Fight or Common Fate?
January 17, 2007
A fossil discovery by amateurs in Montana, reported by the Great Falls Tribune, shows “a meat-eater and a plant-eater – with their tails crossed like swords.” The fossils show “remarkable detail, right down to tendons and teeth.” The three amateur discoverers had been scouting on private property in Garfield County. Finding bone fragments on a […]
Fossil Non-Embryos Quench Cambrian Explosion Fuse
January 16, 2007
Alleged fossil animal embryos in Precambrian rock in China are not. Last year (06/18/2006) and before, researchers found what looked like cleaved embryos in the strata under the Cambrian “explosion” layers. Now, a paper in Nature reclassifies them as giant bacteria, not embryos.1 Some evolutionists had hoped the discovery of animal embryos would […]
Amphibious Assault Against Gradualism
January 10, 2007
A State of the Salamander Address was printed in PNAS recently.1 An international group of scientists looked for evolutionary ancestry and “Global patterns of diversification in the history of modern amphibians.” It would seem Mr. Darwin has a bit of frog in his throat: The fossil record of modern amphibians (frogs, salamanders, and caecilians) provides […]
