While the books' premise does not require evolution to be factual -- mutations are known to occur -- the premise is explored in a way that assumes it is. A storyline in the early 2000s suggested that "regular" humanity, ''homo sapiens sapiens'', would be extinct within a century, replaced entirely with the mutant species ''homo sapiens superior''. Since then, a new event decimated the mutant population and prevented the mutant gene--the "x-factor"--from being passed on to new children, meaning it would be mutants going extinct within a generation, but this is unlikely to last, as some of the effects of the event are already "wearing off" or have otherwise been rectified. | While the books' premise does not require evolution to be factual -- mutations are known to occur -- the premise is explored in a way that assumes it is.
