the most widely accepted theory among scientist is that the last place humans migrated was to America
<span>Undaunted by the often harsh Andean environment, the Incas conquered people and exploited landscapes in such diverse settings as plains, mountains, deserts, and tropical jungle.</span>
<span>The
experience of the new immigrants was different. By 1890, no more free
land was available, so newcomers found jobs in city factories. They
lived in crowded neighborhoods, where everyone shared a common language
and culture.
Hope this helped :)
