Numbers DO say something about the surviveability of a life form.  The
cockroach is one of the most long lived species on the planet, surviveing
severe climactic and geological changes that altered the very face of the
planet.  Humans, by contrast, have only been around for a relatively short
time and may not even survive the next catacliysm.  So if you want something
that will be around in the future... get a cockroach!
