Selvaris vs PikaLearn

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.
