AL-SHAMAHI:
One theory of how
they hunted bears

comes from studies
of the Native peoples

of this region and North Asia
in past centuries.

MCLAREN:
Essentially, a hunter would go

with a, a party to a cave,

smoke the bear
out of the cave,

and entice that bear
to attack a single hunter.

That hunter would be armed
with a bracing spear.

Uh, bear would come

to take the hunter up
in a bear hug,

which is a common thing
that they do.
Yeah.

And the idea is, a bear
would take that hunter

and essentially,
give him a good crushing.

The hunter, at the same time,

would brace the spear
on the ground

and aim it
at the bear's heart.

And so essentially...

Oh.
...the bear would take
the hunter and the spear

into the bear hug,

thereby spearing itself
through the heart.

Perhaps beginning as far back
as 40,000 years ago,

probably in Siberia,

before humans had even reached
North America,

the threat they faced
from wolves

began to transform

Now, we're not exactly sure

something like this.

Wolves would gather
around human campsites.

Now, at first,
maybe humans were terrified.

Maybe they thought
that they wanted to eat them.

But actually,
some of those wolves

weren't interested in that
at all.

They were looking for scraps.

And as they were doing that,

maybe they started fending off
other predators

and protecting
our combined territory.

And because of this,
humans started tolerating

some of the least aggressive,

some of the most docile
of these.

Maybe they even
started feeding them.

In more than one place and time,

our ancestors reshaped wolves
into dogs.

And began to use them

to guard our camps...

Generation after generation,

we selected
the most docile animals

and reared their pups...

The clue is in that word:
plant.

To be put down in one place.

And just like the plants
that they grew,

those early farmers
would've had to have adopted

a very similar lifestyle,

because you couldn't exactly
keep moving

if you had to tend
to your crops.

And so, for the very first time

since the birth of Homo sapiens,

we were no longer
a completely nomadic species.

More and more of us
were quite literally

putting down roots.

Farming supercharged
our capacity

to fuel human activity,

and what emerged
was extraordinary.

Here in Peru, there's a place

where one group began
a new way of living

on a scale unprecedented

The stepped pyramids of Caral

were once lost
under the desert sand.

Archaeologists have uncovered
a vast complex

of ancient structures.

The remains of
what's thought to have been

the first city in the Americas.

And what made it possible

to build these
extraordinary edifices

were the fields of crops
that surrounded them.

Caral became an immense hub
for trading harvested maize,

cotton, and fish from the coast.

It represented a new path
humans could take

towards permanence and stability

that would become possible
because of agriculture.

But it's likely many
of the people in this region

at that time still lived
as hunter-gatherers.

And as they gazed
upon this new way to exist,

would they have wondered

if this was the choice
they wanted to make?

I just can't help but think,

what would it have been like

for people visiting it
for the first time back then?

Because they would've
never seen a city before.

It must have been
so alien to them,

it must've looked like
a place from a different world.

This was a commitment
to a static way of life.

And yet, we don't consider

how tumultuous
the process might have been,

how much social upheaval
might have been involved.

Because for those
who chose to lead this life,

it must have come
with a huge cultural shift,

because humans were becoming
an urban species

for the very first time.

Humans around the planet
stood at a crossroads.

For most of the 300,000 years
our species had existed,

we followed a variety

of nomadic
hunter-gatherer lifestyles.

But in the space
of just a few millennia,

a completely new way to live
had become possible.

Farming in settlements
offered humans an alternative

to lives spent hunting
and gathering as nomads.

It was the dawn of a new era

that would transform the world
forever.
