In their recent examination of a new two-legged dinosaur discovered in New Mexico, evolutionary paleontologists were looking for new clues to untangle their conflicting theories of dinosaur origins. But instead of providing answers, the new dinosaur has joined a growing list of fossil finds that don’t fit an evolutionary picture.

About 35 years ago, Dr. Raymond Damadian invented a technology that transformed medical science. MRI, or magnetic resonance imaging, has been widely used in medical research ever since. Researchers over the years have employed it in a variety of ways, including using it to uncover cancers early enough for effective treatment.

Scientists discovered something remarkable in a recent study—evolution can’t be reversed. In tracing the supposed evolution of a common protein, they introduced mutations to move the protein “backward” to each of its hypothetical transitional stages and discovered that each one wouldn’t work. What does that mean to the theory of evolution?

A media frenzy about life on Mars broke out back in 1996 when researchers announced they had found what they interpreted to be fossilized bacteria on a rock from the red planet. Photos of a little, worm-shaped structure were liberally posted, and the subject was discussed for weeks.

Researchers have described remarkably well-preserved tissue discovered inside a salamander fossil. The fully intact muscle tissues also had blood-filled vessels, and they had not been mineralized like most fossils.
