2. Tierra, by Thomas Ray was one of the earlier proposals toward an artificial evolutionary process that generates life. Tierra was successful in giving rise to unicellular organisms (actually, programs encoded in a 32-instruction machine language). In the original Tierra, there was no externally defined fitness function – the fitness emerged as a consequence of each creature’s ability to replicate itself and adapt to the presence of other creatures.
Eventually, Tierra would converge to a stable state, as a consequence of the creature’s optimization of their replication code. Ray then decided to explore the emergence of multicellular creatures, using the analogy of parallel processes in the digital environment. Enter Network Tierra, which was a distributed system providing a simulated landscape for the creatures, allowing migration and exploitation of different environments. Multicellular creatures emerged, and a limited degree of cell differentiation was observed in some experiments.
