A. Early Primates
Despite some basic signs of culture, these simple beasts roamed the earth grunting, beating their chests, eating the flesh of their young and picking the parasites from one another.
B. Early Man
Man had started to show signs of advanced communication and various forms of primitive art.
C. Man's Golden Age
Men shared advanced thought and ideas in philosophy, literature, biology and all that other jazz. And if they didn't do any of that other stuff at least they had the decency to dress themselves properly in public.
D. The Decline - (** - track pants)
Man's glory days of the 'no shirt no service' days were over. Man's ability to adequately dress himself had waned to the point where it was quite common for men to walk the streets, quite proudly no less, in track pants. Man had concluded there was nothing to be gained from any sort of decent social interaction and had thus forgone the usual social nicety of dressing to a basic standard. Man's capitulation. Social decay. THE DECLINE.
E. Late Man
