tile at a greater speed and with better accuracy than earlier
spears thrown by hand. These new adaptations helped hunt-
ers become more successful in killing ancient bison.
The Folsom Point was in use across North America for
one or two thousand years until about 8000
b.c.e. By 7000
b.c.e. the Folsom projectile point was giving way to a tech-
nology called Plano. This tool-making era lasted longer than
both the Clovis and Folsom periods combined, its earliest
forms dating from 8000
b.c.e. and lasting until about 4500
b.c.e. While Plano Points vary dramatically, even from one
another, typically they were longer, were not fl uted, and
The First Americans
and western Canada, and their
language stock provided the source
language for various dialects spoken
by American Indians in that region
today. These dialects are known
as the Athapaskan (or Athabascan)
languages of the Canadian
Northwest. Yet Na-Dene also proved
to be the source of other native
languages, spoken far to the south.
Centered in today’s U.S. Southwest
(Arizona, Utah, southern Colorado,
and New Mexico), the Apache
dialects, as well as Navajo, fi nd their
roots in Na-Dene. Just how such a
language source could center in two
regions so clearly different as Arizona
and Canada remains a mystery.
The third and fi nal wave of
migrants to the New World arrived
late, almost too late. They came
around 5000
B.C.E. after much of
Beringia was already underwater.
Until 2000
B.C.E. these latecomers—
known today as the Inuit, or, as some
Native Americans refer to them, the
Eskimos—settled all across western
Alaska, including the Aleutian
Island chain. They extended their
settlements across the frozen north
of Canada, settling on both the east
and west shores of Hudson Bay. In
time these people settled as far east
as Greenland. In fact, it would be the
Inuit who would make contact with
the Norsemen called Vikings, around
1000
C.E. The Vikings—from northern
Europe—would represent the next
signifi cant phase of migration to
America.
