What do you base the assumption, that they are sub-human, on? That's scarey considering they've easily outwitted us at every turn to collect more definitive evidence of their existence.
Sas is not evolved into a "human" but a shy Sas.
here is the senerio I would use, so bare with me please. 10 000 years agothere was bold Sas there was not so bold Sas and there was the Sas so shy he had a hard time getting dates. Bold Sas just walks up to Homo Sapian and bashes him over head and bang he has the food of the homo Sapian.
Well Homo Sapian doesn't have a 35 inch bicept like a Sas but he has real big noodles in his head and figures with spears arrows and a few freinds he can Make Bold Sas into an ex Sas so when Bold Sas trys it again he may take out a homo Sapian in the group but generally Bold Sas's start becomoing rare. and not passing on the bold gene. Now Homo Sapians like killing the Sas. One, it elemnates the guy taking his Carabu and Salmon and also makes him look studly to that chick in the white deer skin. So he goes out to kill more Sas's. with his buds. Well bold Sas's are gone so the find some not so bold Sas's hang out eating Samon in the Day. Soon the not so bold Sas gene is not being passed along but the homo sapian hunter and the chick in the white deerskins' are.
So what's left. the Homo Sapian and the few Sas so shy he almost can't get a date. Well now that Bold and not so bold are not around picking up lady Sas's guess what, Sas's so shy is getting more dates, and passing his genes on and his desendants are now being disscussed on the BFF and Blog Radio shows and scaring the hell out of campers, teens in lover lanes, and Marines in the woods at night.
Basicaly Sas has evolved to be elusive, 'cause non elusive Sas became rugs in Mr Homo Sapians cave. Not because they are real smart but because shy was the gene that got passed
