Evolution is confirmed as a core progression system: players train Stackmon and evolve them into more powerful forms. Exact requirements are a separate data problem and are not treated as verified here yet.
Player answer
Quick answer
Training and evolution are confirmed, but exact levels, items and creature-by-creature chains are not verified for the current build.
Confirm the base creature in your current build.
Record the exact condition when an evolution occurs.
Keep the build version with the result before sharing it as a guide.
Current limit: No individual evolution requirement is presented here as a confirmed answer.

What is confirmed
The official store directly connects training with evolution and describes evolved forms as more powerful. Evolutions are also included in the advertised 100+ collection scope.
What a reliable evolution record needs
A future record needs the base creature, resulting form, exact condition, version and reproducible evidence. A name or level copied from a community page is not enough on its own for this site.
Confirm the creature in the current build.
Reproduce the evolution condition.
Record the build or patch.
Keep alternate forms separate from evolution unless the game does so.
How to use this page now
Use it to understand the role of evolution and the verification standard. The site will add a lookup only when enough current chains can produce useful answers without suggesting false completeness.
Verified progression targets
Steam names one achievement for evolving a first Stackmon and another for evolving 15 Stackmons. A separate achievement requires reaching max level with a Stackmon. These targets confirm the breadth of progression, but not the condition for any individual evolution.
