Evolution is a 2001 American comic science fiction film directed by Ivan Reitman. It stars David Duchovny, Orlando Jones, Seann William Scott, Julianne Moore, and Ted Levine. It was released by DreamWorks Pictures in the United States and by Columbia Pictures internationally. The plot of the film follows college professor Ira Kane (Duchovny) and geologist Harry Block (Jones), who investigate a large meteor crash in Arizona. They discover that the meteor harbors extra-terrestrial lifeforms, which are evolving very quickly into large, diverse and outlandish creatures. Evolution was based on a story by Don Jakoby, who originally wrote it as a serious science fiction horror thriller film, until director Reitman hired David Diamond and David Weissman to re-write much of the script into a comedy which Don liked. Shooting took place from October 19, 2000 to February 7, 2001 in California and Page, Arizona, with an $80 million budget, and the film was released in the United States on June 8, 2001. The film grossed $98.4 million internationally. A short-lived animated series, Alienators: Evolution Continues, loosely based on the film, was broadcast months after the film was released.

They quickly learn that the meteor harbors extra-terrestrial nitrogen-based microorganisms that condense millions of years of evolution within a matter of hours: the next day, the microscopic organisms have evolved into asexual fungi and flatworms that cannot yet breathe oxygen, and aquatic life the day after that. After the U.S. Army soon seals off the site, Ira and Harry ask Brigadier General Russell Woodman, Ira's former boss, and the clumsy Dr. Allison Reed, senior researcher in epidemiology at the CDC, to aid in their research, but their efforts fail when two weeks later, Ira goes to court to be allowed to be part of the federal investigation. When Allison questions him as a witness, he reveals that he was discharged from the army in the summer of 1997 after an experiment in May of that year, in which he developed an anthrax vaccine and administered it to nearly 140,000 soldiers. This resulted in terrible consequences, which led
