A Cambrian rock layer is considered to be "Cambrian" because of the particular fossils it contains. But what does it mean when a rock layer designated as "Ordovician" contains distinctly Cambrian fossils? Paleontologists are facing that question after a recent find in North Africa.

Living forms supposedly evolved by adapting to environmental challenges. It is generally assumed that they did this by gradually acquiring the needed genetic mutations until brand new features arose and whole creatures eventually morphed into totally different ones. But does real science support this story?

Few questions hold more intrigue than that of how the universe began. Although the Bible provides a written account of this obviously miraculous event, some reject it and try to explain the origin of the universe without either miracles or miracle Maker.

The Hubble Space Telescope, which had been programmed to search for planets, has found 42 "oddball" blue stars in the Milky Way galaxy. These stars burn so brightly that they consume their fuel much faster than other stars. Though they are found in more abundance in more distant galaxies, the discovery of nearby blue stars presents a particular problem for standard long-age cosmologies.

According to evolution, dinosaurs lived during an age when birds and non-reptile land creatures were either present in just a few "primitive" forms or not at all. But a recent National Geographic online interview offered a summary of fossil discoveries made in a dinosaur-bearing deposit in Madagascar.
