Abstract:

We provide a brief overview of the use of FLs in evolutionary biology and introduce an FL model suitable for individual-based models of species evolution. Our model combines different features of several analytic FL models used in evolutionary biology. Our new model overcomes several difficulties encountered with previous FL models, particularly arbitrary divergence thresholds. We discuss the difficulties encountered during the implementation of our model and how we have overcome these. We present a detailed numerical analysis of the proposed family of FLs that will inform future work based on our FL model.
