Foundlings (Noon Universe)
In the Noon Universe created by Arkady and Boris Strugatsky, the foundlings are a group of 13 humans, who evolved out of the embryos stored in the "sarcophagus". The embryos were discovered on December 26, 2137 by Boris Fokin's group of explorers on an unnamed planet in star system EN-9173. These events are described in the novel Beetle in the Anthill.
