Artificial Life Forms Evolve Basic Intelligence

For generations, the Avidians have been cloning themselves quietly in a box. They’re not perfect, but most of their mutations go unnoticed. Then something remarkable happens. One steps forward, and that changes everything. Tens of thousands of generations down the line, some of its descendents will evolve memory.

Avidians are not microbes, or sci-fi alien life forms. They are the digital offspring of Charles Ofria External Link and colleagues at Michigan State University (MSU) in East Lansing. They “live” in a computer world called Avida External Link, and replicate External Link using strings of coded computer instructions instead of DNA. But in many ways they are similar to real life: they compete with each other for resources, replicate, mutate, and evolve. They—or things like them—might eventually evolve to become artificially intelligent life forms.
