We consider a stochastic model of population dynamics where each individual is characterised by a trait in {0, 1, ..., L} and has a natural reproduction rate, a logistic death rate due to age or competition, and a probability of mutation towards neighbouring traits at each reproduction event. We choose parameters such that the induced fitness landscape exhibits a valley: mutant individuals with negative fitness have to be created in order for the population to reach a trait with positive… CONTINUE READING
