Earliest human migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa of Homo erectus. This was followed by the migrations of other pre-modern humans including H. heidelbergensis, the likely ancestor of both modern humans and Neanderthals. Finally, Homo sapiens ventured out of Africa around 100,000 years ago, spread across Asia around 60,000 years ago and arrived on new continents and islands since then.
Knowledge of early human migrations, a major topic of archeology, has been achieved by the study of human fossils, occasionally by stone-age artifacts and more recently has been assisted by archaeogenetics. Cultural and ethnic migrations are estimated by combining archaeogenetics and comparative linguistics.
<span>Considering the variety of movements covered in the section of your text entitled "The Rise in Cultural Nationalism how did American cultural life in the early nineteenth century reflect the Republican vision of the nation's future?
Jefferson and the Republicans championed the rights of the states and advocated a strict adherence to the Constitution, but once in office, they found new situations that demanded governmental actions that, in some cases, went beyond what the Federalists had done. What caused Jefferson and his party to change their approach to governing, what reservations did they have about what they were doing, and how were they able to rationalize this apparent change in program and philosophy? (Be sure to consult previous chapters when answering this question.)
How did the Federalists respond to Republican programs? If the Federalists favored a loose interpretation of the Constitution, why did they protest when Jefferson used a loose interpretation as well? What was it in the Republican program that the Federalists saw as a threat, and how did they respond?
Many historians view the War of 1812 as the second American war for independence but is this an accurate characterization? In what way did British policies prior to 1812 threaten our independence? Had the United States not fought the war, what might the results have been? Assess these questions, and determine if the United States was indeed fighting for independence."</span>
