A philosophical burlesque, ``Human Nature'' follows the ups and downs of an obsessive scientist, a female naturalist, and the man they discover, born and raised in the wild. As scientist Nathan trains the wild man in the ways of the world - starting with table manners - Nathan's lover Lila fights to preserve the man's simian past, which represents a freedom enviable to most.
