No. Genetic drift and natural selection tend to make different populations different from each other. Since speciation requires that groups evolve differences from each other, genetic drift and natural selection can result in the evolution of differences among populations and therefore can cause speciation to occur. So speciation can occur because of natural selection and genetic drift within groups.
