Ardi Party Is Over
November 25, 2009
The hubbub over Ardipithecus (10/02/2009) may have been premature.  Despite 600 pages of material submitted to Science in October, many doubts and questions remain about the status of this hominin, or hominid, or whatever it was (the nomenclature is confusing and inconsistent even among paleoanthropologists).  In an article by Katherine Harmon in the pro-evolutionary magazine […]

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 […]

Darwinizing Everything
November 16, 2009
150 years after The Origin of Species, it’s clear that Darwin succeeded in one thing: granting biologists free rein to speculate about how everything under the sun evolved.  Anything not understood, or seemingly contrary to the law of natural selection, or to previous speculations, can be shuttled off to future research. Noble amoebas:  You may […]

Soft Muscle Tissue Found in Fossil Salamander
November 6, 2009
More soft tissue has been found in a fossil – this time in a salamander said to be 18 million years old.  The article on PhysOrg called it “the highest quality soft tissue preservation ever documented in the fossil record.”     Unlike the previous discoveries of fossil tissue inside bone or amber, the recognizable […]

No Evolution in 58 Million Years
October 30, 2009
“Plant fossils give first real picture of earliest Neotropical rainforests,” announced a press release from University of Florida.  The fossils from Colombia show that “many of the dominant plant families existing in today’s Neotropical rainforests – including legumes, palms, avocado and banana – have maintained their ecological dominance despite major changes in South America’s climate […]

Cambrian Explosion Solved: Elementary, My Dear Darwin
October 28, 2009
Two articles announced solutions to the evidential problem that most troubled Darwin – the sudden appearance of complex animals at the base of the Cambrian fossil record.  Both of them involve chemical elements.  The only difference is which element.     Science Daily announced a “Novel Evolutionary Theory For The Explosion Of Life.”  The article […]

Trilobites Found in Fool’s Gold: What Does It Mean?
October 27, 2009
Trilobites are icons of the Cambrian and Ordovician periods.  When thousands are found in beds over a wide area encased in pyrite, with no sign of decay, what does it mean?  A team publishing their findings in Geology suggests it means rapid burial.1  Here’s the abstract from their paper: Pyritization of soft tissues is extremely […]

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 […]

Dino Clawprints in the Sandstones of Time
October 6, 2009
Some of the largest dinosaur tracks ever found have been uncovered in France.  The BBC News has a picture of tracks nearly 5 feet across made by sauropods that weighed 30 tonnes.  Tracks of ornithischian dinosaurs in South Africa are being analyzed for clues to dinosaur behavior, reported Science Daily.  The team believes that tracks […]

Step Aside Lucy; It’s Ardi Time
October 2, 2009
A new fossil human ancestor has taken center stage.  Those who love Lucy, the australopithecine made famous by Donald Johanson (and numerous TV specials), are in for a surprise.  Lucy is a has been.  Her replacement is not Desi Arnaz, but is designated Ardi, short for Ardipithecus ramidus – the new leading lady in the […]

Anchiornis: Foot Feathers Confuse Bird Evolution Story
October 1, 2009
The paper on Anchiornis huxleyii was published in Nature,1 along with a News article about it in the same issue by Lawrence Witmer.2  In addition, popular reports were printed by the BBC News, Live Science and Science Daily.     The popular reports are focusing on Xing Xu’s claim that this fossil removes the last […]

Ho-Hum, Another Feathered Dinosaur
September 25, 2009
Another Chinese fossil its discoverers are calling a “feathered dinosaur” has been announced by Nature News.  It is ostensibly a more complete specimen of Anchiornis huxleyii that was announced last January (see 01/21/2009).  The full paper on this specimen is to be published in Nature next week.     The fossil is said to have […]

Human Evolution Celebration Exposed
September 24, 2009
The evolutionary story of human origins is often told like a cultural myth that is intuitively obvious.  Humans emerged in Africa after their ancestors came down from the trees and walked upright.  They began to hunt with stone tools and used fire.  They migrated north out of Africa and populated Europe, overtaking the Neanderthals who […]

Human Evolution Story Confounded – Again
September 9, 2009
Human fossils in Georgia (Asia) have confounded the timeline of human evolution again.  The UK newspaper Independent reported that the 3 skulls of Homo erectus are rewriting the history of man.  If these are as old as claimed (1.8 million years), it would toss overboard the long held belief that modern humans first emerged in […]

Permian Extinction Recovery Story Stretches Credibility
September 4, 2009
It goes without saying that Darwin’s theory fits hand in glove with the geological dating scheme, but how reliable is the latter?  The textbook age names – Permian, Triassic, Jurassic, Eocene and all the rest – have taken on their own life as assumed truths.  Every once in awhile, though, papers are published that require […]
