Questions
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?

The 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.
4
More 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.
5
The 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.

6
Lower 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.

What Route Did the First Explorers Take to Travel
Here?
Land Bridge Theory
Coastal Route Theory
European Maritime Theory

Beringia 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.

Artifacts
  • 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.

  • 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.

    Garrett. National Geographic, Accessed 10/29/06.

11
Coastal 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.

12
European 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.

Everyday 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.
    (Hunter-Gatherers, Microsoft Encarta, 2001).
