Recursive Creators

Life makes life, as we all know. In other cases, life makes artificial life. This trope, however, continues that cycle as those artificial lifeforms make their own artificial lifeforms.

There's a variation where the artificial lifeform (usually a machine) is self-replicating, a... Self Replicating Machine, if you will. It's usually the domain of Nanobots everywhere, which is what makes them so dangerous.

And just when you thought Turned Against Their Masters was an exclusive Human/Robot trope, this may also lead too Robots Enslaving Robots.

May show Mechanical Evolution or Clone Degeneration. See also, Creating Life.

Has nothing to do with a Recursive Reality or Recursive Fanfiction.

Comics

 * In the Marvel Universe, the Celestials created the Kree, who in turn created The Inhumans.

Film

 * Multiplicity: Overworked guy creates clone to do his work for him. Overworked clone creates clone...
 * The android girl (called synthetics) in Alien Resurrection is from a line of synthetics designed by synthetics rather than humans.

Literature

 * The plot of Feet of Clay revolves around golems creating
 * The eponymous (and autonomous) spaceships of Fred Saberhagen's Berserker series.
 * The Hypotheticals from Robert Charles Wilson's novels Spin and Axis are of the Von Neumann type seen below
 * The short Novel Model II by Philip K. Dick has a handful of US Marines find out what has been happening since they gave the deadly robots built to fight off the new URSS the capability to reproduce simply because they were so dangerous nobody wanted to work on them anymore. It's not pleasant.

Live Action TV

 * There's a Star Trek: The Next Generation example, when the android Data creates its own android offspring, Lal.
 * Cylons in Battlestar Galactica. It didn't turn out well for them, either.
 * The imaginatively-named Replicators of Stargate SG-1.

Newspaper Comics

 * In Calvin and Hobbes, Calvin's duplicate begins making his own duplicates. Hilarity Ensues.

Web Comics
"King: For technology we simply build robots which build smaller robots which build smaller robots... and on until they can build machinery as tiny as we need."
 * A Saturday Morning Breakfast Cereal strip shows a couple of scientists coming to the conclusion that we are in a simulated reality. The last panel has a pair of alien scientists celebrating that our universe broke the record for how long it took a simulated reality to moon them.
 * Freefall's Mozart Boids (robot birds) are this.
 * Stanislaw Lem's "constructors" (Mortal Engines (not that one), The Cyberiad).
 * The Dingbots from Girl Genius can create other Dingbots, but each successive generation is stupider and weaker. There are only about three originals ("Queenie Dingbot", "Prime A", and "Prime B") from which the best can be made directly.
 * Similarly, in Gunnerkrigg Court the golems and then robots continued manufacturing more of themselves after their creator's death. Because many of his initial designs were beyond their understanding, subsequent generations were greatly simplified.
 * Acibek in Dominic Deegan: Oracle For Hire created his replacement before his Heroic Sacrifice.
 * In Spacetrawler, this is how the Mihrrgoots mastered nanotechnology.

Western Animation

 * The Multiplicity example is replicated in a Simpsons Halloween Episode, parodying the former.
 * A good one from Transformers Generation One. Wheeljack creates tbe Dinobots from scratch. Years later Grimlock, leader of the Dinobots created the Technobots from scratch. Arguably all of the Transformers count since they were given life by Vector Sigma, a computer, and built by the Quintessons. Not sure if they're fully machine though.

Real Life

 * The entire idea behind The Singularity is that a chain of self-replication among machines of super-human computational ability will render the world completely unrecognizable.
 * The entire premise behind the Von Neumann machines.
