  The goal of Artificial Life research, as articulated by Chris Langton, is "to
contribute to theoretical biology by locating life-as-we-know-it within the
larger picture of life-as-it-could-be" (1989, p.1). The study and pursuit of
open-ended evolution in artificial evolutionary systems exemplifies this goal.
However, open-ended evolution research is hampered by two fundamental issues;
the struggle to replicate open-endedness in an artificial evolutionary system,
and the fact that we only have one system (genetic evolution) from which to
draw inspiration. Here we argue that cultural evolution should be seen not only
as another real-world example of an open-ended evolutionary system, but that
the unique qualities seen in cultural evolution provide us with a new
perspective from which we can assess the fundamental properties of, and ask new
questions about, open-ended evolutionary systems, especially in regard to
evolved open-endedness and transitions from bounded to unbounded evolution.
Here we provide an overview of culture as an evolutionary system, highlight the
interesting case of human cultural evolution as an open-ended evolutionary
system, and contextualise cultural evolution under the framework of (evolved)
open-ended evolution. We go on to provide a set of new questions that can be
asked once we consider cultural evolution within the framework of open-ended
evolution, and introduce new insights that we may be able to gain about evolved
open-endedness as a result of asking these questions.
