Lamarckia is the largest simulspace in the system that that has no regular users, and in fact earns no profit. The pet-project of hyperelite retiree Jean Maes, the simulspace simulates a large ecosystem that functions according to Lamarckian inheritance. Primarily this is accomplished through a supercharged epigenetic system, assisted by manual interventions when necessary. Jean has been criticized by the scientific community for his frequent interventions, preventing more interesting species from exaggerating their traits until they no longer function, but compromising the status of the simulspace as a scientifically valid Lamarckian simulation.
Although existing primarily as an expensive hobby, Lamarckia has spun off some interesting bioware and scientific discoveries, such as organ plasticity.
