The Morphology and Natural History of a Common and Widely

question 25

Multiple Choice

The morphology and natural history of a common and widely distributed butterfly was observed over a 25-year period in Costa Rica.Recent DNA barcoding (DNA sequence analysis) showed that what was once thought to be a single species is actually a complex of at least 10 species.Though caterpillars of these species eat different food plants and have somewhat different habitat preferences than their adult forms, their morphological differences are subtle.There are no differences in reproductive organs.Based on observation alone, there is no obvious reproductive isolation.Which statement best characterizes how different species concepts would consider this group of butterflies?

• A) It would still be considered one species were it not for the morphological species concept.
• B) It would still be considered one species were it not for the biological species concept.
• C) It would still be considered one species were it not for the lineage species concept.
• D) It would be considered one species under the lineage species concept, but multiple species concepts under the other species concepts.
• E) It would be considered multiple species under all species concepts.
