Both sexual selection and ecologi-cal causes of natural selection may result in speciation. In some case, organisms of different species can mate and produce healthy offspring, but the offspring are infertile, cant reproduce. For speciation to occur, two new populations must be formed from one original population, and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed.
