"...in fifty years, do you believe that people will be recognizably human?"
- Greg Bear
 |
| Symb | ||
| A symbiont life form that provides its human with life-giving energy. |
| Each human-symb pair is a closed ecology, requiring only sunlight and a small amount of solid matter to function. The vegetable symb gathers sunlight in space, using it to convert human waste and carbon dioxide into food and oxygen. At the same time it protects the fragile human from vacuum and the extremes of heat and cold. The symb's body extends into the lungs and through the alimentary canal. Each side feeds the other.
...upon permeating the nervous system of its host, [the symb] is born as a thinking being. It shares the human brain. |

Compare this idea with that of the star stone from Roger Zelazny's still-amazing 1976 novel Doorways in the Sand as well as the aliens from Robert Heinlein's 1951 novel The Puppet Masters.
