"Evolution doesn't cause adaptation. Adaptation happens randomly (via mutations and genetic variability due to crossover if I recall correctly),"

But natural selection for or against these mutations is the process of evolution. Ultimately evolutionary forces are what gives rise to all new adaptations. Migration is a source of new alleles in a population, but mutation and recombination (during prophase 1 of meiosis) are the cause of ALL completely new alleles.
