Barricelli's final paper on Artificial Life available here!

In Chapter 5 of Rise of the Self-Replicators I discuss Nils Aall Barricelli’s pioneering work in the 1950s on evolving self-replicating digital organisms. There I mention his final paper on the topic, published in 1987 and entitled Suggestions for the starting of numeric evolution processes to evolve symbioorganisms capable of developing a language and technology of their own.

In it Barricelli discusses how his system might be improved to allow for the evolution of more complex organisms. The paper appeared in a technical report series of the University of Oslo entitled Theoretic Papers and is quite hard to get hold of, so I have now posted it in the Additional Materials section of the book’s web page.
