When rapid adaptation is driven by rare alleles from the standing genetic variation or by a high population rate of de novo adaptive mutation, positive selection should commonly generate soft rather that hard selective sweeps. In a soft sweep, multiple adaptive haplotypes sweep through the population simultaneously, in contrast to hard sweeps in which only a single adaptive haplotype rises to high frequency.
