*Evolution* (2001) is a science fiction comedy film directed by Ivan Reitman. The film stars David Duchovny, Julianne Moore, and Orlando Jones and combines elements of science fiction, comedy, and action.

The plot begins when a meteorite crashes in a small Arizona town, bringing with it an alien organism. Initially, the organism appears to be a simple microbe, but it rapidly evolves into increasingly complex and dangerous forms. The discovery is made by two local scientists, Ira Kane (David Duchovny) and Harry Block (Orlando Jones), who are initially skeptical but soon find themselves in over their heads as the alien creatures begin to pose a serious threat.

The duo teams up with a government scientist, Allison Reed (Julianne Moore), to combat the evolving alien species. The film follows their efforts to understand and stop the aliens, who are growing in size and intelligence with alarming speed. Their mission is complicated by various comedic situations, including the constant bickering between Ira and Harry, and the growing menace of the alien threat.

As the aliens continue to evolve, they develop new abilities and become more dangerous, culminating in a final showdown. The team devises a plan to stop the alien invasion and save humanity from the extraterrestrial threat.
