2Questions
The First Americans Who, What, When, Where,
How, Why?
- Who were the first Americans?
- When did the first Americans start arriving?
- Where did they come from?
- Where did they first enter the Americas?
- How did they travel to the Americas?
- Why did they come to a new land?
- What was daily life like for these First
Americans?
3The Very First Americans - Who Were They?
? The Americas were the last continents on earth
to be occupied by man. ? Before man arrived,
large animals roamed and ruled the land. ?
Short-faced bears ran as fast as horses and were
twice the size of todays grizzly bears. ? 3500
pound ground sloths, 20 feet long and standing
over 6 feet tall roamed the land.
4More Wild Animals
? Teratorns birds weighed 30 pounds, had 10 foot
wing spans, but stalked their prey on the
ground ? Three-toed horses, that disappeared
before Columbus arrived, galloped across the
continent. ? Saber-toothed tigers with 10
canines were dangerous meateaters. ? Mastodons
and Mammoths ? Camels, antelope, bighorn sheep,
lions, deer, moose, fox, otters, and bison.
5The Ancient World Ice Sheets
- ? About 125,000 years ago, the earths last ice
sheets formed and lasted until 12,000 years ago.
- ? Geologists know that during this age, ice
sheets covered more than 30 of the earth,
including much of North America and Europe.
6Lower Ocean Levels Land Bridges
? Because so much of the worlds water was frozen
in ice sheets, ocean levels were 200-500 feet
lower than they are today. ? The lower sea
levels exposed land that today is ocean floor.
Back then, these exposed lands existed as land
bridges.
7What Route Did the First Explorers Take to Travel
Here?
Land Bridge Theory
Coastal Route Theory
European Maritime Theory
8Beringia is the name that scientists call the
land bridge that existed between Asia and North
America.
- Beringia was a land bridge thousands of miles
wide. - Paleoclimatologists believe that the weather in
Beringia was much milder than the weather in the
area is today. - Beringia supported wildlife and plants.
9Artifacts
-
- The tools, to the left, were found near Alaska.
They are made of bird bone, whale bone, and
walrus tusk. - Some of the tools are tiny needles that were used
to make waterproof clothing. - They show that humans had adapted to the northern
climate. - Archaeologist Rick Knecht says these Aleutian
tools show us only a glimpse of who these people
were. All we have are these little piles of
stones and bones. Its like trying to tell
something about our culture by looking at steak
knives.
10- The Enigma of the First Americans
- Geoarchaeologist C. Vance Haynes believes the
first people who entered the Americas were
explorers . . . Probably young people who were
really bent on seeing what was over the next
hill. - The Beringia Land Bridge theory was long
considered the most probable theory, but two
problems with the theory arose - How did the explorers travel thousands of miles
over the relatively barren ice sheets. Some
scientists argue that there was an area free of
ice, a corridor, through which humans could have
walked. - Evidence from an archeological site in Monte
Verde, Chile indicate that humans were living in
South America at an earlier date than the North
American artifacts indicate people were living
here. - (Michael Parfit and Photographer Kenneth
Garrett. National Geographic, Accessed 10/29/06.

11Coastal Route Theory
- Recent evidence suggests that the coast of the
Americas would have been habitable, livable. In a
cave in Alaska, archeologists found the bones of
a 10,400 year old man and tools nearby. - The bones prove that the man ate a marine diet,
fish and sea plants, proving that by 10,000 years
ago, people lived along the coast. - Ancient travelers could have traveled from Asia,
along the coast of the Americas down to South
America. The evidence would have been destroyed
when the ice sheets melted and the ocean levels
rose.
12European Maritime Theory
- Scientists have recently found similarities
between the spear points found at certain
American sites and the spear points made by the
Solutreans, an ancient European culture. - These similar spear points suggest that ancient
man might have traveled across the Atlantic. - The Solutreans might have traveled by boat, or
the Atlantic might have been frozen, and the
Solutreans could have walked.

14Everyday Life for the First American Hunter
Gatherers
- Humans developed farming about 8,000 years ago.
- Before man learned how to grow plants and take
care of crops that would grow well in the same
place year after year, people would hunt small
and large animals, birds, and fish, and they
would gather plants, berries, and roots that were
edible, fit to be eaten. - We call these people hunter gatherers.
- Hunter gatherers didnt live in permanent homes
or villages. Instead they would move from place
to place hunting and gathering food.
