The First Americans Land Bridge Theory
Summary
TLDRThis lesson covers the migration of the first Americans, who crossed the Bering Strait land bridge from Asia to North America around 20,000 years ago. These nomadic hunter groups followed large game like mastodons, deer, and buffalo during the Ice Age. Over time, they evolved from hunting to gathering and eventually developed farming techniques, leading to the formation of larger villages and civilizations. The video highlights the transformation of these early peoples into tribes such as the Cherokee, Lakota, and Apache, and their adaptation to the changing environment and food sources.
Takeaways
- 🌍 The migration to America occurred roughly 20,000 years ago, during the Ice Age.
- ❄️ Glaciers covered about one-third of the Earth's surface, causing water levels to drop and exposing the Bering Strait land bridge between Asia and North America.

Q & A
Who were the first people to come to North America?
-The first people to come to North America were nomadic hunters who crossed the Bering Land Bridge from Asia, around 20,000 years ago.
What was the Bering Land Bridge, and how did it form?
-The Bering Land Bridge, also called 'Beringia,' connected present-day Russia and Alaska. It formed during the Ice Age when glaciers covered large parts of the Earth's surface, causing sea levels to drop and exposing dry land.
Why did these early people migrate to North America?
-The early peoples migrated to North America in search of food, following large herds of animals like mastodons, prehistoric deer, and buffalo across the Bering Land Bridge.
What is a nomad, and how did these people survive?
-Nomads are people who move from place to place in search of food. These early peoples were nomadic hunters who followed animal herds to sustain themselves and their families.
What tribes are mentioned in the script as descendants of these early migrants?
-Some of the tribes mentioned include the Cherokee, Lakota, Cheyenne, Apache, Haida, and others that spread across North, Central, and South America.
How did the lifestyle of these early peoples evolve over time?
-Initially, they were hunters who relied on big game animals for food. Over time, they became hunter-gatherers, supplementing their diet with nuts, berries, and seeds, and eventually developed farming techniques, leading to permanent villages and civilizations.
What were some of the challenges these nomads faced as they migrated?
-One major challenge was the eventual disappearance of large game animals like mastodons, which forced the nomads to diversify their food sources by hunting smaller animals, fishing, and gathering plant-based food.
How did the shift from hunting to farming impact the development of societies?
-The shift from hunting to farming allowed people to build permanent villages, develop agriculture, and create more complex civilizations. It also enabled the domestication of animals and the cultivation of crops.
What are hunter-gatherers, and how did their practices differ from those of the earlier nomads?
-Hunter-gatherers still hunted animals but also relied on gathering seeds, nuts, and berries from their environment, unlike the earlier nomads who relied mainly on large game for food.
What topic will the next lesson cover according to the script?
-The next lesson will discuss civilizations, focusing on what defines a civilization and the characteristics of such societies.
Outlines
🌍 The First Americans' Journey to North America
This paragraph introduces the topic of the first Americans who migrated to North America around 20,000 years ago. It explains how glaciers covering one-third of the Earth's surface caused sea levels to drop, exposing dry land, including the Bering Strait land bridge, which connected present-day Russia and Alaska. This land bridge, known as Beringia, provided a pathway for early peoples to migrate. These groups were hunters following herds of Mastodons, prehistoric deer, and buffalo during the Ice Age, and were known as nomads because they moved in search of food.
🗺️ The Spread of Nomadic Tribes Across the Americas
This section discusses the spread of nomadic groups across North, Central, and South America over the next thousand years. These nomads, who moved to follow their food sources, evolved into various tribes such as the Hohokam, the Patayan, the Cherokee, the Lakota, the Cheyenne, and the Apache. As they spread out over the North American landscape, they began to change their food acquisition methods. Initially hunters, they became hunter-gatherers, and eventually started farming, leading to the development of larger villages and civilizations.
🏞️ Evolution from Hunting to Agriculture
This paragraph delves deeper into the transition from hunting societies to agricultural societies. The first groups to come into North America followed big game animals like Mastodons and ancient elk. As these animals started to disappear, the people adapted by fishing, hunting small game, and gathering seeds, nuts, and berries. Over time, they developed agricultural techniques, learned to tame animals, and planted crops. This advancement in agriculture led to the establishment of permanent villages and the rise of large civilizations.
🏛️ The Birth of Permanent Villages and Civilizations
The final paragraph summarizes the significant changes that occurred as these early people advanced in agriculture. Their ability to plant crops and domesticate animals led to the creation of permanent villages and eventually large civilizations. The paragraph concludes with a teaser for the next lesson, which will focus on what defines a civilization and the characteristics that distinguish a group of people as a civilization.

Highlights
The migration to America happened roughly 20,000 years ago during the Ice Age.
Glaciers covered about one-third of the Earth's surface, which led to the formation of a land bridge between Asia and North America.
The land bridge, known as Beringia, connected present-day Russia to the coast of Alaska.
Early peoples, primarily hunters, crossed Beringia following herds of large animals like Mastodon, prehistoric deer, and buffalo.
These early migrants were nomads, meaning they moved from place to place in search of food.
Over thousands of years, these nomadic groups spread across North, Central, and South America, forming the tribes known today.
Tribes that emerged include the Iroquois, Sioux, Cherokee, Lakota, Cheyenne, and Apache, among others.
These societies evolved from hunters to hunter-gatherers, and finally, to agricultural communities.
The shift from hunting large animals to gathering seeds, nuts, and berries marked a significant change in food acquisition.
As the large game animals began to disappear, the nomads shifted to hunting smaller animals like rabbits and began fishing.
These hunter-gatherers developed techniques for planting crops and began to domesticate animals.
The mastery of agriculture led to the establishment of permanent villages and large civilizations.
The development of farming was a major advancement, allowing the creation of stable, growing societies.
The early peoples' understanding of seasonal changes and land use enabled them to grow crops effectively.
Next lesson will discuss what defines a civilization and the characteristics of early civilizations.
Transcripts
hello and welcome to this online lesson
today we'll be talking about the first
Americans that crossed the landbridge
and came to North America so let's go
ahead and get
started so this massive migration to
America happened roughly 20,000 years
ago glaciers covered about onethird of
the Earth's surface and so much water
that we see today in the oceans and even
in the Great Lakes was frozen in these
glaciers that pieces of dry land began
to emerge the bearing straight land
bridge between Asia and North America so
that would be present day Russia and off
the present day coast of Alaska that had
formed because all this water was dried
up and this gave the early peoples a
pathway to this new
world so this land bridge was known as
baronia and if you look on the map on
this slide you can see kind of where it
would be today and on a present day map
and the reason that all of these new
peoples came to the new world is because
these were groups of hunters that
crossed the land bridge following herds
of Mastadon prehistoric deer and buffalo
this all happened during the Ice
Age and during the Ice Age these groups
of people that followed the herds of
wild animals around because that was
their food source were known as Nomads
and Nomads are people who move from
place to place in search of
food so over the next Thousand Years
these nomadic groups spread across North
Central and South America becoming the
tribes that we know of today such as the
hos
the son the phatan the Cherokee the
Lakota the Cheyenne the Apache and many
other tribes that you can see right here
on this
map so as these groups began to spread
out over the vast North American
landscape they began to evolve
especially in terms of how these
societies acquired food they moved from
hunting societies where they were
following the game from place to place
in order to feed themselves and their
families they became then they became
hunter gatherers which they still hunted
but they also relied on the nuts the
berries the seeds of the earth to
sustain their appetite and finally they
began to start farming and this is what
led to the creation of larger Villages
and
civilizations so a little bit more about
the hunting societies they again these
were the first groups to come into North
America they filed the big game animals
across baranga into this new world the
herds of mad on the herds of ancient ALK
and deer and buffalo and these nomadic
people followed the game from place to
place in order to feed themselves and
their
families while these big game animals
provided a great food source and they
also provided a sour of source of
clothing for the peoples they began to
disappear so Hunters began to look to
different food sources they began to
fish hunt small games such as rabbits
and they began to gather seeds and nuts
and berries to sustain their
appetites and as these hunter gatherers
began to learn more about the land in
the seasons as they changed around them
they began to develop techniques for
planting and growing different crops
they were able to tame animals and plant
more crops and they had developed an
advanced system of agriculture also
known as farming these people began to
build permanent Villages and giant
civilizations
emerged that about wraps things up for
today next time we'll be talking about
civilizations what they are what
characterizes a group of people as a
civilization and we'll see you next time
