    "abstract": "A simple mathematical homogeneous model of competition is used to describe\nNeanderthal extinction in Europe. It considers two interacting species,\nNeanderthals and Early Modern Men, in the same ecological niche. Using\npaleontological data we claim that the parameter of similarity, between both\nspecies, fluctuates between 0.992 and 0.997. An extension of the model\nincluding migration (diffusion) is also discussed nevertheless, extinction of\nNeanderthal seems unavoidable. Numerical analysis of travelling wave solution\n(fronts) comfirms the extinction. The wave-front-velocity is estimated from\nlinear analysis and numerical simulations confirm this estimation. We\nconjecture a mathematical formulation for the principle of exclusion between\ncompetitive interacting species (Gause).",
