A reseаrcher studying the wild relаtives оf tоmаtоes describes two mountain subpopulations that decent from a larger valley population. In the East population, flower diameter is 10–12 mm, leaves are 8–10 mm wide and 80–90 mm long, and the stem is spiny. In the West population, flower diameter is 9–13 mm, leaves are 7–11 mm wide and 78–85 mm long, and the stem is spiny. When the researcher grows plants from both population in the greenhouse and hand-pollinates them, the East–West crosses do not set any fruit (and the East–East and West–West crosses do set fruit).According to which species concept(s) are the East and West populations different species?
