Adaptive Mutations
Biological
LithoidNot at creationAdaptive Mutations is a mutations species trait in Stellaris 4.5.2 that costs no trait points. It is for Biological and Lithoid species, added later, not at species creation. Opposite of Wilderness.
What Adaptive Mutations does
Modifier lines by where they apply, as the game prints them; then the trait's own effect text.
No modifier lines in the files.
Auto-Modding Traits automatically adjust to better suit the job that a 
Pop is currently working.
Adaptive Mutations picks modifiers from the Adaptive Mutations Auto-Mod Trait List
Opposite traits
A species cannot have this trait together with any of these.
WildernessWhen modification offers it
species_potential_add and species_possible_add: when genetic or robotic modification shows and allows the trait (the wording is ours).
- Can add mutation traits
In the game
By introducing hyper-adaptive nucleotides into the genetic structure of this species, they are capable of evolutionary changes in real time.
Adaptive Mutations: questions
How many trait points does Adaptive Mutations cost?
