  As a part of our effort for studying the evolution and development of
cognition, we present results derived from synthetic experimentations in a
virtual laboratory where animats develop koncepts adaptively and ground their
meaning through action. We introduce the term "koncept" to avoid confusions and
ambiguity derived from the wide use of the word "concept". We present the
models which our animats use for abstracting koncepts from perceptions,
plastically adapt koncepts, and associate koncepts with actions. On a more
philosophical vein, we suggest that knowledge is a property of a cognitive
system, not an element, and therefore observer-dependent.
