Many species, of course, developed predatory habits, and special organs of offense, such as muscular boughs as strong as pythons for constriction, or talons, horns, and formidable serrated pincers.

This hypothetical binary partner, which has never been seen but which has nevertheless been given the dramatic name Nemesis, passes, once per orbital rotation, through the so-called Oort Cloud, the belt of perhaps a trillion comets which orbits the...
