Here's a fun thought.

In the old world, agriculture started in the Mediterranean and temperate regions. The domesticated species are mostly winter annuals or adapted to a Mediterranean climate (dry summers, wet winters).

New world species are mostly subtropical or tropical species. Corn, potatoes, pumpkins, beans, tomatoes, peppers, etc are all warm weather crops. This is a major reason the large population centers developed in the tropical and subtropical areas.

Populations in the North America domesticated other species like lambsquarters and erect knotweed. However these species were not as productive and they gave them up when corn and beans were traded for from present day Mexico.

So the least experienced farmers with the species, were the first ones the Europeans ran into in North America. :-)
