    "abstract": "Parapatric speciation is studied using an individual--based model with sexual\nreproduction. We combine the theory of mutation accumulation for biological\nageing with an environmental selection pressure that varies according to the\nindividuals geographical positions and phenotypic traits. Fluctuations and\ngenetic diversity of large populations are crucial ingredients to model the\nfeatures of evolutionary branching and are intrinsic properties of the model.\nIts implementation on a spatial lattice gives interesting insights into the\npopulation dynamics of speciation on a geographical landscape and the\ndisruptive selection that leads to the divergence of phenotypes. Our results\nsuggest that assortative mating is not an obligatory ingredient to obtain\nspeciation in large populations at low gene flow.",
