TOEFL Success Read the passage to review the vocabulary you
have learned. Answer the questions that follow.
The migration from Asia to North America across the Bering Strait
(perhaps by land bridge) was a monumental event in human history.The
process of overspreading the Americas took more than 1,000 years, or 30
generations.This might seem to confirm common sense—that slow travel
was inherent in any great migration without wheeled
vehicles across unknown terrain. Further thought shows
that this process was remarkably fast—about 10 northsouth
miles per year, on average. The Americas were
populated at an astounding pace, when one considers
the physical limits of the human body and the physical
features of the American continents. Legs of humans can move only so
fast under the best of circumstances, and they work even slower over
mountain passes or deserts. Populations spread through the diverse
regions of the Americas (grasslands, eastern forests, coastal swamps) and
needed to adapt to their new environments.The migrants’ lifestyle had
evolved over the years to that of professional nomads ensuring that they
would find the resources needed to survive.
