Evolution
Evolution is a high-energy physical warm-up game in which players begin as a simple organism and progress through stages of evolution by winning rounds of rock-paper-scissors against other players at the same evolutionary level. Players physically embody each stage (amoeba, chicken, monkey, human), creating a chaotic, noisy environment in which everyone is playing simultaneously. The game is self-organizing, requires no improv experience, and works well with large groups as an icebreaker. Evolution builds physical commitment, willingness to look foolish, and the social bonding that comes from shared silliness.
Structure
All players begin as amoebas: hunched low, making bubbling sounds, and slithering around the space. When two amoebas meet, they play rock-paper-scissors. The winner evolves to the next stage (chicken); the loser remains an amoeba.
Chickens strut around the space, flapping their wings and clucking. When two chickens meet, they play rock-paper-scissors. The winner evolves to monkey; the loser devolves back to amoeba.
Monkeys lope around the space, scratching and making monkey sounds. Two monkeys play rock-paper-scissors: the winner evolves to human (the final stage); the loser devolves to chicken.
Humans walk normally and may cheer, celebrate, or observe the remaining evolution in progress. In some versions, humans can devolve back to monkey by losing to another human, keeping everyone in the game. In other versions, reaching human status ends that player's participation, and the game continues until all players have evolved.
The game is played simultaneously by all participants, creating a room full of competing organisms at various evolutionary stages. The energy level is high from the start and escalates as players move through stages.
The facilitator can end the game at a natural peak of energy or when a target number of players have reached human status.
How to Teach It
How to Explain It
"Everyone starts as an amoeba: tiny, crawling, making amoeba sounds. When you find another amoeba, you play rock-paper-scissors. The winner evolves one stage: amoeba becomes chicken, chicken becomes monkey, monkey becomes human, human becomes superhero. If you lose, you de-evolve. Reach the top."
Demonstrate each evolutionary stage before starting: show the amoeba posture and sound, the chicken walk, the monkey lope, and the human celebration. Clear physical and vocal definitions prevent confusion during the fast-paced gameplay.
The exercise works best when players commit fully to each stage's physical embodiment. Amoebas who stand upright or chickens who walk normally reduce the game's energy and comedy. Coach for maximum physical commitment: the sillier each stage looks and sounds, the more effective the exercise.
A common pitfall is players rushing through rock-paper-scissors without engaging with their opponent. Coach for eye contact and genuine interaction during each encounter. The social connection of each brief rock-paper-scissors moment is part of the exercise's bonding function.
The devolution mechanic (losing sends a player back to a lower stage) is critical to the game's energy. Without it, the game drains quickly as players reach human status and stop participating. Keeping everyone cycling through stages maintains the chaotic energy.
Evolution is an excellent opening exercise for workshops or performances because it requires no explanation of improv concepts, gets every player moving and making noise immediately, and creates a shared physical experience that bonds the group before more demanding exercises begin.

Related Exercises
Rock Paper Scissors
Rock Paper Scissors is a warm-up exercise that uses the familiar hand game as a platform for building ensemble energy, celebrating failure, and practicing commitment. In improv contexts, the game is typically played with escalating stakes, exaggerated reactions, and progressive variations that transform a simple competition into a group bonding experience.
Alien Tiger Cow
Alien Tiger Cow is a full-body version of rock-paper-scissors played in a circle. On a count, each player strikes one of three poses: alien (fingers on head), tiger (claws bared), or cow (udders mimed). Players who choose the minority pose are eliminated. The exercise is a fast physical warm-up that generates laughter and group energy.
House, Creature, Flood
House, Creature, Flood is an energetic group warm-up and tag game in which players form groups of three: two players create a "house" by facing each other with their arms raised and joined overhead, and one player stands inside as the "creature." When the caller shouts "flood," all creatures must find a new house; when they shout "house," the house-builders separate and find a new creature; when they shout "earthquake," everyone reorganizes entirely. The game builds rapid responsiveness, physical coordination, and the experience of group reorganization under pressure.
Animals
Animals is a physical transformation exercise in which players move through the space embodying different animals called out by a facilitator or chosen by the participants. Each new animal demands a complete shift in physicality, tempo, weight, rhythm, and energy. Players explore how different creatures occupy space, move, breathe, and interact, using the animal as a gateway to expanded physical vocabulary and heightened commitment to transformation. The exercise appears across multiple performance traditions, from Augusto Boal's Games for Actors and Non-Actors to Seraphin Eldredge's mask improvisation work, and is a foundational component of both actor training and improv pedagogy. Animals develops range of physical expression, spatial awareness, and the ability to commit fully to a physical choice without self-consciousness.
Honkasaurus Rex
Honkasaurus Rex is an energetic warm-up exercise in which players adopt the persona of a loud, honking dinosaur and move through the space interacting with each other through dinosaur sounds and physicality. The exercise releases inhibition through committed absurdity, builds group energy, and establishes a norm of full physical and vocal participation at the start of a session.
