From vast underground caverns, working class armies pour forth to defend their highly structured communal way of life.  Are these feudal societies in the Middle Ages? No, they're ants! NOVA looks at the most successful life forms on the face of the planet in Ants: Little Creatures Who Run the World, hosted by Harvard University's internationally renowned ant authority, naturalist Edward O. Wilson. What's impressive about ants is how they practice what we preach: family values. All ants belong to extended families and carry their prey home to share. Unselfishness is the rule. Everything they do is for their colony's good.  For them, socialism works.Special DVD features include: materials and activities for educators; a link to the NOVA Web site; scene selections; and closed captions.     On one DVD5 disc.
