ancient civilisations and empires in history

let's list 'em.
off the top of my head, there's ancient greece (philosophy! sculpture! tragedy!), rome (gladiators), the byzantine empire/constantinople (mosaics, awesome architecture), ancient india (uh.. elephants?), ancient egypt (pyramids and papyrus!) .. ancient china (vases, funny hats and robes), feudal japan (ninjas)

am I missing any? add please.

I don't know why people insist on saying that humankind hasn't changed at all since leaving africa...  Adaptation never stopped.  This is obvious in the physical appearance of different populations from different areas.  I don't know what this thread is about, but to say that there hasn't been any change is to ignore something basic and obvious.
