Another Crow Species Impresses Scientists with Tool-Making Skills
May 26, 2009
Who would have thought that crows rival chimpanzees in intelligence? Members of the corvid group, which includes crows and ravens, are amazing researchers with their ability to make tools. Previous studies with New Caledonian crows (08/09/2002, 10/07/2007, 02/23/2007) impressed researchers with the birds’ abilities to fashion simple tools out of available materials to […]
Cool Bird Tricks
May 19, 2009
Evidence continues to mount that a lot of capability is packed into a little bird’s brain. We should use the phrase bird-brain to honor smart animals. I C U: Mockingbirds can recognize individual humans. Disturb a mockingbird nest, and the parents will single you out from a crowd and go into attack mode, researchers at […]
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: Wheres 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 […]
Amazing Fossils: Do They Help Darwin?
March 19, 2009
Some remarkable fossils have been found recently. According to the reports, scientists are not sure what to make of them, even though evolutionary language is liberally applied to the interpretation. Octopus: The earliest fossil octopus is 100% octopus. A rare well-preserved octopus fossil, as unlikely as finding a fossilized sneeze according to Live Science, shows […]
Songbirds Sing on a Fast Wing
February 17, 2009
Purple martins and wood thrushes are common songbirds of the eastern United States. Until recently, it has not been possible to follow their movements accurately. Now, a team of biologists in Toronto, Erie and Cambridge was able to track them with tiny geolocators. They found that the little birds fly farther and faster than previously […]
The Early Bird Gets the Just-So Story
February 3, 2009
If a catastrophic world event wiped out the dinosaurs, why did birds survive? They’re smaller and more delicate, it seems. National Geographic published a new hypothesis: they out-thought the doomed dinosaurs. “Birds survived the global catastrophe that wiped out their dinosaur relatives due to superior brainpower, a new study suggests.” A couple of […]
Is Natural Selection Losing its Appeal?
January 28, 2009
Some recent science reports sound like they are ready to cast Darwin’s key phrase natural selection overboard, or at least demote it from its leading role in evolution. These articles each hint that long-held beliefs are being challenged. Make room: Science Daily asked, “Natural Selection Not The Only Process That Drives Evolution?” Scientists at Uppsala […]
Feather Evolution Proved?
January 21, 2009
Another claim of feather evolution was reported in PNAS.1 Creationists have long claimed that the evolution of feathers from reptilian scales is an intractable problem for Darwinists (example: 1994 article from Creation magazine). Does the paper provide incontrovertible proof that feathers had evolved in dinosaurs before birds took flight in the air? Beipiaosaurus, […]
Watch for Flying Giraffes (and Convergent Evolutionists)
January 9, 2009
Imagine giraffe-sized animals that could fly. They lived. National Geographic News has an illustration of an extinct pterosaur, tall as a giraffe, that was able to leap into the air and flap its wings for sustained powered flight. Live Science discussed work by Michael Habib [Johns Hopkins U School of Medicine] on the […]
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 […]
