Tierra Artificial Life Simulation

Tierra is a ground-breaking artificial life simulation developed in the early 1990s. It was designed to study the processes of evolution and ecology in a digital environment. Unlike standard computer programs, Tierra hosts digital organisms that compete for CPU time and memory space, effectively acting as energy and territory. This environment allows for the emergence of complex biological phenomena such as parasitism, immunity, and social behavior within a virtual 'primeval soup'.

The project was originally written in C and has been maintained by the scientific community and enthusiasts for decades. It remains a foundational tool in the field of Artificial Life (ALife) and is frequently used in academic research to demonstrate how natural selection can operate on digital code. The simulation is open-source, allowing researchers worldwide to build upon the original framework created by Thomas S. Ray.
