Genesis
by H. Beam Piper
Was this unfortunate expedition the end of a proud, ancient race, or the beginning of a new race? There are strange gaps in our records about the past. We find traces of human-like things, but suddenly a human seems too advanced to be the "next step" in a well-connected chain of evolutionary evidence. Perhaps something like the events of this story gives an answer to the riddle. Immerse yourself in the distant past and discover the fascinating origins of advanced technologies that allow future inhabitants of Earth to travel between parallel universes with their whims. This entry in H. Ray Piper's popular series "Paratime" lives on in Martian colonists who visited Earth hundreds of thousands of years ago.
