Question

Plants from the genus Solanum include such common vegetables as potatoes and eggplants. The many species include some plants native to tropical West Africa as well as closely related species native to tropical South America. What might you reasonably conclude?

Answer 1

The plants from West Africa and South America were once together as one population.

Step-by-step explanation:

This could be used as a source of proof for continental drift. When West Africa and South America were connected as one continent, known as Pangea, these two now existing plants were one species of plant in the genus Solanum. As the continents drifted apart the plants evolved separately on each continent according to their different environments. Now they are just closely related species as they have evolved more differences.
