Wisconsin Glaciation - Role in Human Migration

Role in Human Migration

Prehistoric human migration was greatly influenced by the last glacial period, known in North America as the Wisconsin glaciation. In the late Wisconsin era, a land bridge across the Bering Strait allowed the first humans to reach North America from Asia (an alternative theory is migration along the coast; see Settlement of the Americas). Human migration routes opened during interglacial periods in Europe and Asia as well.

Famous quotes containing the words role in, role and/or human:

    Language makes it possible for a child to incorporate his parents’ verbal prohibitions, to make them part of himself....We don’t speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.
    Selma H. Fraiberg (20th century)

    Of course, some men are very effective caregivers [of elderly parents]. But this situation occurs far less frequently for males than females, because it is a role reversal. For women, caregiving is an expected duty; for men, it is an unexpected expression of love or devotion.
    Tish Sommers (20th century)

    No Raven’s wing can stretch the flight so far
    As the torn bandrols of Napoleon’s war.
    Choose then your climate, fix your best abode,
    He’ll make you deserts and he’ll bring you blood.
    How could you fear a dearth? have not mankind,
    Tho slain by millions, millions left behind?
    Has not conscription still the power to weild
    Her annual faulchion o’er the human field?
    A faithful harvester!
    Joel Barlow (1754–1812)
