One Million Years B.C. Edit

A Clockwork Origin Edit
A Clockwork Origin is a play on Anthony Burgess's 1962 dystopian novel A Clockwork Orange and the 1971 film adaptation by Stanley Kubrick with the same name. Like the novel and film, A Clockwork Origin spins a drama out of rival ideological claims about the nature of nature. In the novel and film human nature is at issue. Is human nature fixed or plastic? In the television episode all of nature is at issue. Is life the product of design or accident? The 'fixed' and 'design' positions are fundamentally conservative or rightist while the 'plastic' and 'accident' positions are fundamentally liberal or leftist.
The word "origin" in the title refers to Charles Darwin's Origin of Species, the famous book in which his theory of natural selection was outlined.
South Park Edit
The talking flying Spaghetti Being is a reference to the South Park episode "Go God Go", which also delved into the controversy of teaching evolution, which in itself is a reference to Bobby Henderson and his parody religion "The Church of the Flying Spaghetti Monster".
