The earliest known ancestor of modern-day birds took to the skies by gliding from trees using primitive feathered wings on their arms and legs, according to new research by a University of Calgary paleontologist. In a paper published in the journal Paleobiology, Department of Biological Sciences PhD student Nick Longrich challenges the idea that birds began flying by taking off from the ground while running and shows that the dinosaur-like bird Archaeopteryx soared using wing-like feathers on all of its limbs. "The discussions about the origins of avian flight have been dominated by the so-called 'ground up' and 'trees down'...

Once again, a NASA space probe is supporting the 6,000-year biblical age of the solar system. On 14 January 2008, the Messenger spacecraft flew by the innermost planet of the solar system, Mercury. It was the first of several close encounters before Messenger finally settles into a steady orbit around Mercury in 2011.1 As it passed, it made quick measurements of Mercury’s magnetic field and transmitted them successfully back to Earth. On 4 July 2008, the Messenger team reported the magnetic results from the first flyby.2 As I mentioned on the CMI website earlier,3,4 I have been eagerly awaiting the...

Footprints in the ash By Sid PerkinsMay 29th, 2008Humans may have been walking around what is now central Mexico 40,000 years ago HUMAN PRINTSFootprints (one left) left in volcanic ash that fell in central Mexico’s Valsequillo Basin about 40,000 years could be evidence that humans have inhabited the Americas far longer than previously confirmed. Laser scans of the prints (right) confirm their human origins, the researchers report today at the American Geophysical Union meeting. Footprints left in volcanic ash that fell in central Mexico’s Valsequillo Basin about 40,000 years ago are evidence that humans have inhabited the Americas far longer...

An armored fish was about to become a mom some 380 million years ago. Though the primitive fish perished, its fossilized remains remarkably reveal an embryo and umbilical cord inside the soon-to-be mother's body. The discovery marks the oldest evidence of an animal giving live birth, pushing the known record of such reproduction back by some 200 million years. It also supports the idea that internal fertilization in vertebrates (animals with backbones) originated in a group of primitive fish. "When I first saw the embryo inside the mother fish, my jaw dropped," said researcher John Long, a paleontologist at Museum...
