About this game

Species: Artificial Life Real Evolution is an evolution simulator that allows you to create, destroy, observe and tinker with life on it's never ending, harsh march of refinement! Simulated from the very first principles of evolutionary science:

Variation

  • Every creature is uniquely defined by its genes.

Mutation

  • Child creatures are slightly randomly modified versions of their parent(s).

Natural Selection

  • The environment affects every creature in their struggle to survive.

Observe or Guide

Whether you just want to observe, watch and study as the tree of life constructs itself from a single species, or you want to be an active influence on the development of the species in the game, the choice is up to you! Take a hands-on approach by using the nursery, an isolated area where you can tinker with the gene pool to your heart’s content. Use rovers to decide which creatures get to eat today and which ones starve! Create global catastrophes like an ice-age or a world-spanning flood to weed out the most vulnerable species. Or simply sit back and watch the life-and-death saga unfold!

Tell Your Story

However you treat your evolutionary sandbox, we give you the tools to tell it’s story! View every single evolutionary step in detail using the clade diagram, see where each species are living using the satellite map, get a better picture of how varied your gene pool actually is with the web of life, and view every possible detail on each creature using the creature inspection tools.

    Where to next? - 0.15.0

    Lately I've been moving towards fatigue, sleep, temperature and exposure to the elements all needing to be much more important survival needs than they are right now. Let's put all of these mechanics under the umbrella of 'habitat'. Eventually, habitat will be almost as significant as food as far as survival and selection pressures go, one they will need to balance against seeking food in order to survive long enough to reproduce. Unfortunately, I find the current vegetation model wholly inadequate to support my plans for this stuff. It has failed me for the last time. So it's time to take what I've learned, throw the whole system into a volcano, and build a cleaner, more elegant and far more ambitious replacement. Here's the design goals for the new system, in rough order of priority: The tree's need to be 3 dimensional structures. Multiple 3d interaction points for fruit, foliage, shelter, perches and nests. The tree types need to serve a purpose in the ecosystem. Shelter tree's should not provide food and food tree's should not provide shelter. This will allow me to ensure the two do not generally grow in the same location. The tree's need to be performant. They're not the centerpiece of the simulation: their role doth not merit that they drink deeply from the fountain of FPS. The tree's should evolve. Evolving tree's is probably the second most requested feature, after flight. It was always planned, though never as a centerpiece of the game. So, let's discuss! You can read the rest of this post over here, on the development blog.
