In 2–3 sentences, discuss pros and cons of agricultural dispersal.

Answer 1

1) The potato originated in the Andean highlands of present-day Peru and Bolivia because wild Solanum tuberosum species evolved there and were domesticated by indigenous peoples who selected tubers adapted to the region’s varied microclimates and soils.

2) Domesticated in the Andes several thousand years ago, the potato was carried to Europe by Spanish explorers in the 16th century and gradually adopted across Europe in the 17th–18th centuries, becoming a staple by the 19th century. Fried potato preparations (claimed by Belgium or France) developed later and were spread worldwide and industrialized in the 20th century through processing and fast-food chains.

3) Pros: dispersal of crops like the potato increases food calories, dietary diversity, and economic opportunity across regions. Cons: it can introduce pests and diseases, encourage vulnerable monocultures and loss of local crop diversity, and cause ecological or cultural disruption when introduced species displace traditional systems.
