The primary aim of the KLI Theory Lab is to highlight interconnections between topics of problems of research on evolution and cognition that look theoretically or methodologically promising. Quite often such correlations remain unrecognized because of the disciplinary closure that characterizes the organization of the scientific enterprise. As an arbitrary example, consider Lamarckian inheritance: this issue has been a bone of contention in artificial life research, in the study of cultural evolution, in evolutionary economics, evolutionary epistemology, and (to a lesser extent) evolutionary developmental biology, yet few of the participants in these debates seem aware of what has been going on beyond their own turf. The KLI Theory Lab is designed to allow users to track such kinds of interconnections easily. Its original design features make the KLI Theory Lab also very suitable for advanced literature searches in the domain of evolution and cognition research at large and in several of its specific areas.
