  The evolution of complexity has been a central theme for Biology and
Artificial Life (Bonner, 1988; Bedau et al., 2000). Complexification has been
interpreted in different ways: as a process of diversification between evolving
units (Bonner, 1988) or as a scaling process that is related to the idea of
transitions between different levels of complexity (Smith and Szathmary, 1995).
There have been previous workshops on this topic, e.g. (Heylighen et al., 1999;
Lenaerts et al., 2002), but many open questions still remain. Trying to answer
these questions from a general perspective might not immediately produce
concrete answers for the different fields that are interested in this topic.
Consequently, this workshop is organised with a particular focus in mind: The
emergence of complexity through evolutionary mechanisms. Primarily we want to
have a discussion on evolutionary and related dynamics as mechanisms for
producing complexity. Furthermore, we want to bring together historical and
novel research in this context.
