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.
When it came to the Congress to approve the joining of the United States in the League of Nations it was blocked by the Republican opposition, especially from Senators William Borah and Henry Cabot (D).
The U. S. public opinion was still disappointed over the outcomes of the war. Also, the Republican Senators did not like what they thought to be a violation of the U.S. sovereignity: the covenant of the League in it's Article X predicted that in case of a member being attacked all the others should defend it.
This added to the historical isolationism of U.S. diplomacy stopped the country from joining the League of Nations despite its inspiration on President Woodrow Wilson’s Fourteen Points.
Option 2: Small farmers could no longer work on common lands and had to move to cities for work.
The Enclosure Acts, as a series of Acts between the 17th and 18th centuries, authorized the enclosure of open fields and common land in England and Wales, creating legal property rights to land that was held in common before.
As a result, thousands of smalls farmers couldn't work in the lands anymore, which force them to move to cities for work. Such people mobilization ended up contributing to the industrial revolution later on.
There is no perfect profile of a terrorist. This is one of the main findings in the growing body of literature around terrorism.
<span>Terrorists and those radicalised towards extremist ideologies come in all shapes and sizes. Yet, one of the key features that has appeared to distinguish terrorists from mass murderers is that they have been motivated more clearly by an ideology than by personal reasons. Increasingly, this line is becoming harder to draw.</span>
