Which population would be most likely to undergo relatively rapid allopatric speciation? (ebook module 14.4)a group of birds develops a unique set of mating preferences so that they are unlikely to mate with other birds of the same species in the same geographic area. a population of flowering plants lives along the shore of a pond about one kilometer from the nearest neighboring population. hummingbirds regularly fly back and forth across this distance and transport pollen between the two populations. a population of snakes becomes separated from other populations on a very large island that is formed by rising sea levels. occasionally, a snake or two swims from the mainland to the island or from the island to the mainland. a group of wild horses is transported from wyoming to a small desert island, previously without horses, off the coast of california. no additional horses reach the island thereafter.
