Partly botanical and partly insectoid humanoids with a sense of wonder and curiosity about the world. Evolvanians are a unified species with a strong collective consciousness.
Evolvanians are physically very weak and contribute little to a colony's defence. However, their populations grow incredibly fast and manipulate flora to sustain an entire colony without the need to construct farms. In-Game Description
The Evolvanians are a Minor Faction that can be found throughout a galaxy. They typically prefer warm planets with plenty of water. When a planet with a native Evolvanian population is colonized, their population automatically joins the colony and can contribute to the planet's development.
Benefits to a Colony
With a x2 growth multiplier, Evolvanian populations grow faster than any other civilization. Additionally, Evolvanians produce such an abundance of sustenance by themselves that building Farms is unnecessary. The colony can support the planet's max population size (of both primary and secondary civilizations) without farms, freeing up a significant number of workers that would otherwise be needed for this.
On the flip side, Evolvanians are physically very weak, with a Strength of just 0.1x, so are ineffective in combat. This is partially offset by their typically large populations and high Home Guard enlistment of 35%. They also have a lower tolerance for being taxed than any of the playable Major Factions, although this can be mitigated by building Entertainment structures. When developing an Evolvanian colony, the primary challenge a player will face is keeping them in employment; colonies of this kind will grow extremely quickly and cannot be restricted by not building farms. As a Minor Faction, their excess population also cannot be moved by ships with Personnel Transport modules.
Evolvanians have reasonable synergy with all the organic Major Factions, but particularly the Ripchee, which also prefer warm, predominantly water planets. Although the Syntis prefer very different living conditions, the naturally high growth rate of Evolvanian worlds makes them especially valuable for the slow-growing Syntis.
A previous version of the Evolvanian's description implied that the species exists as a single hive mind, and that meeting one of them is effectively meeting the whole species. They were also stated to be capable of vegetative reproduction; one Evolvanian can literally remove parts of its body, which will become a full-grown being in a very short period of time. This explains their high population and growth rate.
