Drag, merge and evolve! Combine two identical creatures to evolve them into something new - and keep going until you unlock all 48 species.

Probably Science: Evolution is a relaxing merge game and idle game where life evolves in your hands. Start with a tiny blob in a primordial puddle and merge your way through 9 hand-crafted worlds, from prehistoric camps and ancient deserts to neon cyber cities and an anime future.

SIMPLE TO PLAY, HARD TO STOP
Drag one creature onto another to merge them. That's it. No complex systems to learn - just satisfying evolution, one merge at a time.

A BRANCHING EVOLUTION TREE
After the second world, YOU choose your path. Three different civilizations branch out, each with its own creatures and its own final world. Replay to discover them all.

48 UNIQUE CREATURES TO COLLECT
Every creature is hand-drawn and original. Fill your collection, unlock the Memory Roadmap, and see how far evolution can go.
