During
the
Ice
____________________
,
____________________
humans
crossed
a
land
____________________
that
connected
Siberia
to
Alaska
.
Later
on
,
ice
____________________
because
of
climate
change
and
sea
level
____________________
.
It
was
impossible
for
these
people
to
go
back
.
Early
humans
lived
in
____________________
and
were
____________________
so
they
roamed
all
day
long
.
They
followed
____________________
of
large
animals
.
Years
later
,
they
became
____________________
and
collected
fruits
and
seeds
while
hunting
smaller
animals
or
fising
.
Finally
,
humans
evolved
to
become
____________________
and
worked
the
land
,
grew
____________________
and
later
harvested
them
.
This
situation
was
the
beginning
of
small
____________________
that
much
later
will
become
civilizations
.
In
this
communities
,
grops
of
natives
living
together
,
or
____________________
,
the
leader
was
the
____________________
.
Native
Americans
didn't
live
in
____________________
anymore
(
as
cave
*
people
did
)
.
Instead
they
lived
in
____________________
(
similar
to
tents
)
,
____________________
(
where
many
families
lived
together
)
or
____________________
(
tuttle
shaped
house
)
and
had
more
sophisticated
weapons
(
no
longer
rocks
!
)
such
as
the
bow
and
____________________
or
the
____________________
(
a
combination
of
axe
and
hammer
)
.
These
peoples
are
our
ancestors
,
let's
love
and
respect
them
.
