Selvaris
Evolution in real time
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Watch natural selection unfold live on an entire planet: creatures with their own neural network adapt, hunt, flee – or go extinct.
Watch evolution unfold in real time – on an entire planet.
Selvaris is an evolution simulator: plants, herbivores and carnivores live, eat, hunt and reproduce on a globe you can spin freely. Every creature passes its traits on to its offspring – with small mutations. Those that are faster, more efficient or more skilful live longer and have more offspring. Natural selection, live before your eyes.
CREATURES THAT LEARN
Every animal is controlled by a small neural network: it senses food, predators and its own energy reserves and decides for itself where to go. Over the generations, each species improves its shared memory – successful strategies prevail.
WHAT YOU CAN OBSERVE
• More than 20 heritable traits – from speed and sight range to armor and bite power, all the way to plant toxicity and root depth
• Live charts of population size and average age
• The average genes of every species at a glance
