Hunter-Gatherers and the Neolithic Revolution
Summary
TLDRThis episode explores the evolution of humans from hunter-gatherer societies to the advent of agriculture during the Neolithic Revolution. It discusses human origins in Africa, the Out of Africa migration, and the shift to a settled lifestyle with the discovery of farming. The video highlights how this transition led to the development of cities, technological advancements, and the emergence of social classes, contrasting the benefits and challenges it brought to human existence.
Takeaways
- 🌏 The first humans evolved in Africa at least 195,000 years ago, with the oldest known fossil being 'OMA one' discovered by Richard Leakey.
- 🧬 Mitochondrial DNA suggests humans could be as old as 338,000 years, but archaeological evidence is yet to confirm this.
- 🌱 The 'Out of Africa' theory posits that humans originated in Africa and migrated to all other continents, driven by population pressure and resource scarcity.
- 🌐 Humans reached Asia around 100,000 years ago, Australia around 50,000 years ago, and the Americas around 14,000 years ago during the Ice Age.
- 🏞️ Hunter-gatherer societies, the first on Earth, were nomadic due to the need to follow food sources, which limited their technological advancements.
- 🔍 Hunter-gatherers had a division of labor with men hunting and tool-making, and women gathering food, making clothing, and tending to children.
- 🍲 Persistence hunting was a method used by early humans, leveraging bipedalism and superior stamina to outlast prey.
- 🌾 The Neolithic Revolution, marked by the discovery of agriculture around 10,000 BCE in southern Iraq, led to permanent settlements and the formation of cities.
- 🏛️ The establishment of agriculture allowed for food surplus, storage, and the growth of the global population, but also introduced new risks like famine and disease.
- 🏗️ With the advent of agriculture, technology advanced, and social classes emerged, leading to inequality and the end of the egalitarian nature of hunter-gatherer societies.

Outlines
🌏 Origins and Migration of Early Humans
The script begins by discussing the evolution of humans, dating back at least 195,000 years, with the oldest known human fossil, OMA-1, discovered by archaeologist Richard Leakey in 1967 CE in the lower Omo Valley of Ethiopia. It emphasizes that humans originated in Africa and migrated globally, a theory known as 'Out of Africa.' This migration was driven by population pressure and the need for resources. The script outlines the movement of humans from Africa to Asia, Australia, Europe, and the Americas, across the Bering Sea during an Ice Age around 14,000 years ago. It also mentions that while archaeology supports a human age of 195,000 years, mitochondrial DNA suggests an even older origin of at least 338,000 years, although this is not yet substantiated by archaeological evidence.
🏞️ Life in Hunter-Gatherer Societies
The second paragraph delves into the lifestyle of hunter-gatherer societies, the first human societies on Earth. These societies were nomadic, following the movement of their food sources, which limited their technological advancement. They relied on hunting, gathering, and fishing for sustenance, with a division of labor that was egalitarian, valuing all members equally. The script highlights the limitations of this lifestyle, such as the difficulty of supporting large populations and the lack of sophisticated technology, including writing. It contrasts the life during the Paleolithic Age, characterized by nomadic living and simple technology, with the Neolithic Age, which began with the discovery of agriculture around 10,000 BCE, leading to permanent settlements and the formation of cities.
🌾 The Neolithic Revolution and Its Impact
The final paragraph focuses on the Neolithic Revolution, a pivotal moment in human history when agriculture was discovered, possibly by a woman in southern Iraq around 10,000 BCE. This discovery marked the transition from the Paleolithic to the Neolithic Age and brought about significant changes in human life, including the establishment of permanent residences, the formation of cities, and advancements in technology, such as the use of metals like copper. However, it also introduced new challenges, such as vulnerability to climate changes affecting food production, increased risk of diseases due to denser populations, and health issues related to less active lifestyles and diets. The paragraph also discusses the social implications, including the emergence of social classes and the end of egalitarianism, as some professions became more valued than others.

Transcripts
hello and welcome students to another
episode of history at home in today's
episode we will examine hunter-gatherer
societies and a major turning point in
human history the Neolithic Revolution
let's begin by discussing the first
humans on earth our fossil records show
that humans evolved at least a hundred
and ninety five thousand years ago and
we have archaeology that proves this
archaeologist Richard Leakey discovered
the fossilized remains of OMA one the
oldest human ever discovered and here
are the fossilized remains that Richard
Leakey discovered of OMA one and Richard
Leakey excavated these fossilized
remains in 1967 cee we also know that
humans first evolved in Africa and we
know this because archaeologists
consistently find the oldest human
remains in this continent and the oldest
human remains
again that's OMA one were discovered
within the lower Omo Valley in the
modern-day country of Ethiopia and here
is the continent of Africa and within
this red dot here is the country of
Ethiopia and if we zoom in further on
Ethiopia we see the lower Omo Valley
here this is where Richard Leakey
discovered oma 1 and again omo 1 is the
oldest human on fossil record lastly
although the archaeology says that
humans are one hundred and ninety five
thousand years old
humans are undoubtedly even older than
that our mitochondrial DNA suggests
humans are at least three hundred and
thirty-eight thousand years old however
right now we do not have the archaeology
that supports this number but maybe a
discovery in the future will be made
that verifies this number now so far we
have exclusively talked about humans in
Africa but obviously humans are
everywhere today
and this is because our ancestors
migrated throughout the globe and this
migration is known as the Out of Africa
theory the Out of Africa theory states
two things first it states that humans
originated in Africa and it also states
that humans simply walked to the other
six continents of Earth so let's take a
closer look at the Out of Africa theory
and diagram what this migration looked
like
so the first humans originated in Africa
a hundred and ninety five thousand years
ago and slowly over the years as the
human population started to grow humans
began to move throughout Africa and what
is driving this need to move is
population pressure the planet is
experiencing a slow population growth
during this time and as more people join
the planet the amount of available
resources like food in territory become
increasingly scarce this forces people
to move and it's not even really like a
choice for them because if they don't
move they will not survive so people
start to move south they start to move
west and some head up the banks of the
Nile River cross over the Sinai
Peninsula and leave Africa all together
now
a small group of humans begin entering
an entirely new content and that content
is Asia this happens around a hundred
thousand years ago and the population
pressure continues to force people to
move and eventually we reach Australia
by boat around fifty thousand years ago
and we begin to reach Europe about forty
thousand years ago but when humans first
begin reaching Europe the earth is
experiencing an ice age now the ice age
is a period in time in which the
Northern Hemisphere became incredibly
cold in space our planet naturally
revolves around the Sun but our planet
revolves with a tilt of about 23 and a
half degrees the Ice Age occurred
because earth's tilt was a little bit
more extreme than 23 and a half degrees
it was actually closer to 24 and a half
degrees and this put the northern
hemisphere further away from the Sun and
since the northern hemisphere is now
further away from the Sun it received
less solar radiation and in northern
hemisphere it became much much colder
and covered in huge glaciers and ice
sheets and during the Ice Age a small
group of humans began to walk across
these glaciers and ice sheets from Asia
a
across the Bering Sea and into the
Americas about 14,000 years ago now
these ice sheets have since disappeared
and Asia and North America are no longer
connected but 14,000 years ago they were
and this is how humans ended up in the
Western Hemisphere from there humans
walked south and eventually reached into
Mesoamerica and eventually got even
further south into South America and
humans entered South America around
12,000 years ago and this is what the
Out of Africa theory explains number one
it explains the humans originated in
Africa
and number two humans got to the other
six continents simply by walking now
let's talk about hunter-gatherer
societies and how they functioned and
how they were organized hunter-gatherer
societies were the first societies on
this planet and they are called
hunter-gatherers because this is how
they secured their food they either
hunted prey or gathered edible plant
life and because their food moved
whether it was animals migrating in
seasons changing hunter-gatherer
societies tended to be nomadic so this
is one of the limitations of hunting
gathering societies they need to live a
nomadic lifestyle they are constantly on
the move because they need to follow
food and they lack a permanent home
because of this this movement also
limited their technology they could not
advance dramatically in regards to
technology because they never developed
ready and running as a direct response
to an ability hunter-gatherers never had
which was agriculture they did have
technologies such as the spear bow an
arrow
obsidian knives fire stone axes and
musical instruments but that is about
the height of hunter-gatherer technology
they never developed much sophisticated
or advanced technologies because they
don't invent something as basic as
writing and basic writing actually is a
result of agricultural societies finally
food is scarce and this means
hunter-gatherer populations and global
populations stay relatively low
gatherer tribes tend to reach a ceiling
of about 30 people and this is because
it's just too hard to feed more people
than that with a hunting-gathering
lifestyle and also our global population
around 10,000 BCE is around 1 million
people hunter-gatherer societies also
had a clear division of labour and
tended to be egalitarian both men and
women had specific jobs with men being
the hunters and tool makers and women
taking on a variety of jobs like
gathering food making clothing creating
fires and raising the tribes kids and
since all jobs within the group were of
the utmost importance for survival
Society was egalitarian all members of
the society were valued equally the
hunters in the hunting gathering
societies they mostly hunted by fishing
and a fish for their food and this was
the preferred way of hunting to secure
food because it doesn't take or use a
large amount of effort or energy and it
was much safer than conducting the other
mode of hunting which was persistence
hunting persistence hunting is a very
exhaustive and long-winded way of
outlasting your prey and the goal of
persistence hunting was simply just to
outlast your prey and in to move in for
the kill when the animal is too
exhausted to move and humans are able to
do this because we have several key
advantages over other animals we're
bipedal meaning we walk on two legs we
can carry stuff with our open hands and
because our sweat cools our bodies more
efficiently than other alternatives like
panting and this helps us prevent from
overheating we also have superior
stamina than any other animal that has
ever lived and these abilities and these
advantages allow us to conduct these
persistence hunts finally our constant
pursuit for food led us to one of the
most important discoveries in human
history a discovery that totally changed
human existence and this discovery is
known as the Neolithic Revolution the
Neolithic Revolution is when humans
discovered agriculture now we don't know
the name of the person
who discovered agriculture but we can
take an educated guess on a few items we
believe agriculture was discovered by a
woman in southern Iraq around 10,000 BCE
and this discovery is where historians
draw a line between the Paleolithic Age
and the Neolithic Age this discovery
will totally revolutionize the way
humans live and we can see this by
comparing the life of humans during the
Paleolithic Age with the life of humans
during the Neolithic Age so during the
Paleolithic Age this is a time period
that lasts from 2.6 million years ago
until about 10,000 BCE whereas the
Neolithic Age goes from 10,000 BCE
again that's the discovery of
Agriculture until about 4500 BC and
during the Paleolithic Age the only way
humans got food was by hunting and
gathering and this also means that they
were nomadic and consistently
exclusively nomadic during this time
period however during the Neolithic Age
again after the discovery of Agriculture
people start to establish permanent
residences and they begin to form cities
and this is a result of knowing exactly
where the food will be and we know
exactly where the food will be because
of Agriculture also Paleolithic people
had very simple technologies they are
limited to technologies like the bow and
arrow Spears and obsidian knives but
once we discovered agriculture and we
leap into the Neolithic Age we start to
see technology improve and humans begin
to experiment with metals like copper
lastly the Neolithic Revolution brought
on some great changes to the human
existence but these changes were a mixed
bag not only were they good but they
were also bad and this new way of life
this agricultural lifestyle created many
benefits and many setbacks first one
major benefit we gained from agriculture
is that we can control how much food we
grow which allows us to grow a surplus
this means humans can grow more food
than they can possibly eat at one time
and we can store food in save food for
emergencies however since we are now
getting food from planting seeds in the
grounds
we'd also become vulnerable to changes
in armed
armen changes such as droughts floods
and an early frost will directly impact
the amount of food we grow and we are
now at risk of falling into famine
however we do get another Pro from
Agriculture another Pro of Agriculture
is that our global population begins to
grow with more food we can start feeding
more people but the downside to this is
that we begin to live amongst more
people and more animals so disease
become a larger risk we also also start
to live in one permanent location and
cities begin to form which is good and
the first major cities on earth begin to
form in modern-day Iraq and this image
here is a reconstruction of arguably the
world's first major city which is I root
again in modern-day Iraq here's what it
looks like today and this ruin here is a
public building known as the ziggurat
and that is what's pictured here and the
ziggurat was a multipurpose building
it's stored a rooks surplus screen it
was also a temple to various gods and
goddesses and it was also the
headquarters of the government of a roof
however living in a permanent location
also had a negative side effect on our
health our health suffers because we
live and are staying in one location
more often and not moving as much we
also begin to eat less healthy foods
because agricultural foods are less
healthy on average than
hunting-gathering foods early
agriculturalists are also shorter than
our hunter-gatherer ancestors and we
have way higher rates from other issues
such as cavities obesity and heart
disease
this again is because we are less active
now and have a poorer diet than
hunter-gatherers lastly with agriculture
we get new jobs and we begin to see in
advance in technology since we are now
able to produce a surplus of food people
will begin adopting professions to work
and these professions will advance our
technology but with professions comes
inequality some jobs are seen as being
more skilled and valuable to a society
and social classes begin to form if your
job required a high degree of skill and
is valuable to the society
your job became even more important and
others you also became now a member of
what we call the upper class if your job
is in manual labor and unskilled you
begin to plummet into the lower classes
egalitarianism is non-existent in
agricultural societies and social
inequality is a major problem even in
modern societies today
alright that's all I have for you for
now thanks for watching
