African Migration Essay

The African origin of early modern clements 200,000150,000 historic period ago is without delay well documented, with archaeological data suggesting that a major migration from tropical eastward Africa to the Levant took manoeuver between 130,000 and 100,000 years ago via the presently hyper-arid Saharan-Arabian desert. The thoroughfare out of East Africa leads across North Africa, through the Nile corridor, and across the rose-cheeked Sea, or across the Indian Ocean and the strait of Bab el Mandeb to the Arabian peninsula and beyond to Eurasia. Most of this interconnected overturnmass of the so-cal direct Old World, the Continental area encompassing Africa, Europe, and Asia, received migrants from East Africa by about 1.5 jillion years ago.This migration was dependent on the occurrence of wetter climate in the region. Whereas there is good evidence that the southern and central Saharan-Arabian desert go through increased monsoon precipitation during this period, no unequi vocal evidence has been found for a corresponding rainfall increase in the northern part of the migration corridor, including the Sinai-Negev land bridge between Africa and Asia.The major feature of world populations through cadence is their increasing numbers. It is likely that many early human migrations resulted from the pressure of such(prenominal) demographic increases on contain food resources disease, drought, famine, war, and intrinsic disaster intent among the most important causes of early human migrations. Approximately 100,000 years ago, the first migrations of Homo sapiens out of their African homeland likely coincided with the business leader to use spoken language and to control fire. Over the next 87,000 years earthly concern migrated to every continent, encompassing a wide variety of natural environments. The Americas were the last continents to be reached by Homo sapiens, about 13,000 years ago.why these earliest migrants left Africa to colonize the world is a composite, important question. The answer is likely to be found in a web of be factors centered around human behavior, specifically behavior selected to reduce insecurity and increase the individuals fitness for survival. Calculated migration must have resulted from information sharing, bail bond building, memory, and the ability to negotiate all skills that necessarily accompanied increasingly Gordian societal and cultural groups. The increasing complexity of existence inevitably led hominids out of Africa, resulting in a global distribution of diverse human groups.Increasing population may have prodded the migration of some groups. Armed with the attributes of culture, the distinctive, complex patterns of behavior shared by human groups, humans eventually capable to and conquered virtually all global environments. Whatever the nature of human origins, whenever or wherever human societies and cultures first appeared, the peopling of our globe has been a product of migrat ion from place to place. Given the small numbers of people and the vast distances they traversed, and considering their technologically limited modes of transportation, the movement of people around the globe seems miraculous.The examples of global colonization describe below depended on interactions between people and between people and their environments. Gradually, past during the Middle Stone Age (perhaps 100,000 to 200,000 years ago), distinct patterns of interaction among humans and between them and the landscapes in which they lived emerged. Because the distinctive physical and social environments to which humans adequate were themselves constantly changing, cultures too continually changed. That early humans acquired technological and social skills can be inferred from widespread evidence of their material culture rock and roll tools and utensils, carved figurines, rock and cave art, and the like, dating from about 40,000 years agowhich has been found in most parts of the globe.The development of language in spades furthered the social and technological evolution of humans and facilitated systems of reciprocity and social exchange. For example, the form of labor in food production and the exchange and transportation of goods and products were greatly expedited by speech. Being able to assign different tasks to different individuals furthered cooperation and render the processes of social and cultural evolution.http//www.learner.org/courses/worldhistory/unit_readings_3.html http//www.learner.org/courses/worldhistory/unit_overview_3.html
