The blindsnake, a small subsurface burrower, is not often seen, but when it is many mistake it for a worm.¹ Researchers have constructed an evolutionary history for these creatures, partly from biological data and partly from evolutionary assumptions.

Sir Isaac Newton's classic laws of physics apply well to large-scale phenomena like planetary orbits or apples falling from trees. But they seem to fall short in describing what happens at the tiniest levels--such as inside an atom.

For decades, the media and Hollywood have promoted the idea of life on Mars, yet scientific observations have shown that the red planet is utterly inhospitable.¹ The surface of Mars is sterile, yet many still hope to find evidence that life could have existed there.

Evolution's search for the "missing link" between man and ape has a long and troubled history. Australopithecus sediba is the latest fossil find that is claimed to represent evolutionary human ancestors. But the remains of this extinct ape provide several solid clues that contradict any evolutionary relationship to man.

Partial remains of two skeletons were discovered in a cave in South Africa, and some scientists think they may be another addition to humanity's evolutionary tree.
