Awindstorm transports a few seeds of a plant species from island a, where the species is abundant, to island b, where prior to this event the plant species was not found. the environmental conditions on the two islands are very similar, but the islands are located far away from one another. over time, a small population of this plant becomes established on island b. a biologist samples plants on both islands and finds that allele frequencies on island a differ substantially from allele frequencies on island b at several genetic loci not known to affect survival or reproduction. based on this information, the observed genetic changes mostly likely resulted from
