“”Big fleas have little fleas,
Upon their backs to bite 'em,
|—The Siphonaptera poem by Augustus De Morgan|
An infinite regress or homunculus fallacy is when an argument relies on a series of never-ending propositions, where the validity of one proposition depends on the validity of the one which follows and/or precedes it.
One example of a viciously infinite regression arises in intelligent design creationism, which states that there are problems in the theory of Darwinian evolution by natural selection which can only be resolved by invoking a designer or first cause without proposing a solution to the immediate question, "[[Irreducible complexity#So who designed God?|Who designed the designer?" Despite that, the response to this is an example of special pleading: creationists assert that every being needs a cause, but God is an eternal presence which did not need a cause. No evidence for this has ever been presented for peer review, or critical analysis of any kind.
The "Turtles all the way down" anecdote illustrates a popular example of infinite regress:
“”A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever", said the old lady. "But it's turtles all the way down!

The term "homunculus" first appeared in Paracelsus' writing on alchemy, De Natura Rerum (1537), referring to what later became known as sperm after the invention of microscope. In folklore and in literature, homunculus often refers to a miniature fully-formed human. In the Eastern Bloc, homunculus has referred to attempts to remold people to be "without sexual, high intellectual or high emotional 'centres'".:178 More recently, Daniel Kalder has used homunculus to refer primarily to the heads of puppet states who felt compelled to follow the party line while at the same time not showing any innovation from the party cannon. Stalinist examples include Khorloogiin Choibalsan of Mongolia, Georgi Dimitrov of Bulgaria, Klement Gottwald of Czechoslovakia, Enver Hoxha, Kim Il Sung, and Konstantin Chernenko of the Soviet Union.:212,216,242,252,279
