People populate the ecosystem with two-lobed, spiking brains with dopamine-modulated neural plasticity. They sense the world, hunger, thirst, explore, and learn. Each newborn (coyote, deer, or person) inherits its parents' brain structure and physical traits with small mutations, so survivors shape the next generation. Watch the ecosystem grow organically, or switch on Survivor to live in it and care for your cat companion.
