WILKINS: You can see bones running into the section there and here,

WESTSCOTT WILKINS: One of the things that we wondered

with so many of these tusks around,

could it have been, did they all fall into the river somewhere... Oh, I see.

...and then get washed down in one big event?

But what we're looking at is not a high-energy environment.

If, if it was a washout, you would expect to see

more debris in the channel,

more debris in the sediment around the tusks.

But this is basically lying in, in, where it fell.

And the same with the tusk over there.

So we think, you know,

they could have just died and fallen.

But it's, it's a bit of a coincidence, really.

Spectacular fossils like these have always fascinated us.

Hundreds of years ago,

it was thought that mammoth tusks

belonged to mythical beasts.

♪ ♪

In Siberia, mammoth remains were once thought

to be from huge underground burrowing creatures.

In 17th-century Europe,

mammoth bones were said to be those of giants,

or unicorns.

By the 19th century,

mammoths were described as prehistoric animals,

but they were thought to have existed long before humans.

Then, in 1864 in France,

a piece of mammoth ivory was found

with an engraving so accurate, it was clear

that the artist had seen a living mammoth.

The engraving shows a woolly mammoth,

the most recent species on the mammoth family tree.

We now know that early mammoths first evolved in Africa

around five million years ago,

and then spread into Europe and Asia.

Around 1.7 million years ago,

steppe mammoths evolved that grazed the grassy plains.

They then moved into Europe and North America,

where Columbian mammoths later appeared.

The famous woolly mammoths developed

around 700,000 years ago, adapted for colder climates,

and they eventually spread first into Europe,

and then North America.

So which kind of mammoth lived in Britain at our site?

♪ ♪

To find out,

mammoth evolution expert Steven Zhang

is examining the remains found at the site.

The teeth have given him a crucial clue.

ZHANG: Looking at a mammoth tooth is like

looking into a barcode for the mammoth itself.

We start by counting the number of enamel ridges, so...

This one has about 18,

which is a very typical number for a steppe mammoth.

Looking at this piece of tooth,

we know that it's a last molar or a wisdom tooth.

So we know this was a fully grown adult,

except

this is one of the smallest steppe mammoth teeth

there probably is in existence.

It's like

finding a German shepherd the size of a Westie.

♪ ♪

ATTENBOROUGH: These teeth appear to be from a population of small

steppe mammoths.

Their reduced size could be a consequence

of food becoming less abundant.

If a steppe mammoth was here now,

you would see that it wasn't particularly hairy,

a sign that the climate must have been quite temperate.

And as for size, well, the female was about my size,

male a bit bigger, and the baby,

well, I guess, like that.

Must've been rather enchanting.

(baby elephant squeals, adult lowing)

ATTENBOROUGH: There are also remains of another type of mammoth.

ZHANG: Over here, I would say this is a typical woolly mammoth.

So these two different kind of beasts

were occurring at the same site.

One possibility was that this site

was a habitat shared by both steppe and woolly mammoths,

or, as woolly mammoths migrated westward

from Siberia into Europe,

they started to mingle with local steppe mammoths.

This is interesting,

because not often do we see a snapshot like this.

To find out which type of human was living

at Cerney Wick, I've come to a secure facility in London.

It holds one of the largest collections

of prehistoric artifacts in the world.

Curator Nick Ashton is a renowned expert

on these ancient tools.

He begins by showing me simple flint tools found

near Happisburgh on the east coast of England.

ASHTON: We know that in Africa they'd been making

these tools for some two to three million years.

But this is the earliest evidence that we have

in Northern Europe of humans reaching this far north.

Dates to an astonishing 900,000 years ago.

So it's... How much?

900,000 years ago.

Really?

So it's the earliest evidence

for humans in Northern Europe.

ATTENBOROUGH: In 2013, Nick's team made

a truly extraordinary discovery at Happisburgh.

A storm washed away sand on a beach

and revealed ancient footprints set in hardened mud.

They were the oldest human footprints ever documented

outside of Africa, but within two weeks,

they had vanished, washed away by incoming tides.

It's thought that early humans spread out of Africa

around two million years ago.

A million years later,

some of their descendants reached Britain.

What sort of people was it who did this?

I mean, did they have clothes of any kind?

Were they covered in hair?

I mean, do we, how, do we know what they looked like?

We, we actually know very little,

but the species of human

in Europe at that time was Homo antecessor.

They would have looked very similar to ourselves,

apart from slightly different facial...

But they became Neanderthals.

We have sites all the way

as far as Siberia,

and then we have a whole pile of sites in Europe.

Doesn't mean that they are a European species.

It just means

that a lot of the archaeologists are actually

in Europe and were digging in their own backyards.

We've got this massive array, actually,

of Neanderthals in this whole region.

And if you look at that region,

that's a number of different environments,

and a number of different climates, as well.

And do we know what they looked like?

Yeah, so Neanderthals were very similar to us,

but there were crucial differences.

So, for example, we know that Neanderthals, on average,

were, well, they were shorter.

So male Neanderthals would have come in at about

five foot four, five foot five.

But, you know, people have said,

"Well, if you got a Neanderthal,

"you gave him a shave, and you give him a bowler hat,

you put him on the New York subway, would anyone notice?"

And then somebody else obviously said,

"Well, that probably says more about the New York subway

than it does about Neanderthals." (laughs)

But the point stands, you know.

How different were they, really?

ATTENBOROUGH: Back at the site,

the team is finding that nearly all the tusks and bones

are lying in a single layer of sediment,

suggesting the mammoths all died around the same time.

What could have killed a group

of mammoths in such a short period?

WILKINSON: And we can trace this layer pretty much all the way around

to the tusk on the far side, now.

So it's, they're all...

It's all the, formed at the same time.

And we can't see flooding?

'Cause I'm just trying to think what's,

what's forcible enough to move a tusk.

No, there's nothing, I mean...

This is, this is weird, 'cause there's not enough mud.

There's not enough, there's no flood. No.

They just died in this area for some reason. Yeah.

ATTENBOROUGH: Ben is doubtful that the mammoth got stuck in the mud.

GARROD: The mud's deep, but it's not

up to a mammoth's armpits deep.

Disease? I mean, there's nothing, really,

in terms of, of modern relatives, that...

the elephants...

that would kill a whole group that quickly in one site

at one time to explain this.

And we've got adults and juveniles, as well.

So it's not the classic elephant graveyard

all, all being left in one site, either.

And it leaves this idea, this possibility,

that it was people.

So were they chasing them in?

Were they corralling them somehow?

Were they... I, I don't know.

But that's almost weirder, because I can't imagine

quite early Neanderthal people

bringing down a bunch of mammoths.

Because these things were tons

of anger and intelligence.

♪ ♪

ATTENBOROUGH: Evidence suggesting that

Neanderthals could successfully

hunt mammoths is extremely rare.

But this is the island of Jersey,

and here, at La Cotte de St. Brelade,

piles of mammoth bones have been found

that suggest that Neanderthals may indeed

have been killing mammoths here.

Archaeologist Matt Pope

has been studying the site for years.

POPE: Our first glimpse of La Cotte de St. Brelade,

towering up above us.

GARROD: Oh, wow,

It's like this huge cathedral fortress, isn't it?

It's beautiful.

♪ ♪

POPE: We can see a lot of the site from here,

the main granite structure,

the arch that takes you through to the north ravine,

and in front of us,

the west ravine, the main open space.

ATTENBOROUGH: The site has been investigated since 1881.

And over the years, archaeologists excavated

down into the ravine.

At two levels, they discovered

heaps of bones of butchered mammoths.

The mystery is how these bones got there.

POPE: An original explanation, and a very good one,

was that the mammoth were all herded together,

by Neanderthal hunters,

and driven over the cliffs to their death.

So you imagine... GARROD: From right up there?

POPE: From right up there.

I mean, that's quite a thought, to think of

a whole herd of mammoths coming cascading

over the edge right there.

POPE: It's a good theory, but it's not a very good

headland for actually concentrating a herd.

There is simply no way

you could funnel the mammoth into this ravine.

They'd be splitting off into all different directions.

We've been recently relooking at those bone heaps

and looking at the evidence,

and we put forward an alternative idea.

And that idea is that these bone heaps

didn't form in one go... Mm-hmm.

In mass kills.

But actually, they formed over a long period of time,

and the hunting was taking place out here

on the surrounding landscapes.

They were bringing these bones back,

and then over time,

they put these heaps of bone together.

And this whole area, as we look at it now,

it's this beautiful coastline

that stretches out to the, the Channel here.

But this would have all been one big grassy plain.

POPE: We've got the seabed landscape mapped.

There's little cul-de-sacs where you get dead ends,

and you could control game.

And we know from other Neanderthal sites where

hunting is taking place, they love landscapes

in which they control game.

Probably the whole Neanderthal community

would be involved in hunting,

corralling, controlling,

moving, isolating particular members of a herd.

♪ ♪

ATTENBOROUGH: Most archaeologists now think that the Neanderthals

were capable of hunting large prey like mammoths,

as they seem to have done in Jersey.

But it would be much harder to trap them

on the flat grasslands of Cerney Wick.

Perhaps the river might have slowed the mammoths down.

But how would the Neanderthals have killed them?

Wooden spears may well have been used.

Wood, of course, rots away quickly,

so we're very unlikely to find one.

But there are some.

♪ ♪

In 1911, in Essex,

a wooden spear tip was found in waterlogged soil.

And in 1948,

stronger evidence of spear hunting was uncovered.

A spear was found within the fossilized ribs

of a straight-tusked elephant.

Then, in 1995,

at a mine in Schöningen in Germany,

ten miraculously well preserved Neanderthal spears

were found lying among the skeletons

of around 50 horses, the oldest complete

prehistoric hunting weapons ever found.

Archaeologists had assumed these early hunters

thrust their spears into the flanks

of prey at close range.

But could spears like this have been thrown

at mammoths from a longer distance?

To find out, we asked a wood carver

to make exact replicas of the Schöningen spears from spruce,

the same shape, weight, and type of wood

as the ancient spears.

MILKS: Hi, guys.

GARROD: We've brought you some spears.

ATTENBOROUGH: Annemieke Milks is an investigator

of Neanderthal hunting methods.

She wants to see how well these replica

Neanderthal spears will perform in the hands

of Bekah Walton and Harry Hughes,

two of Britain's leading javelin throwers.

I'm really curious to see what

an experienced thrower makes of how they feel.

WALTON: They are the right length,

compared to a normal spear.

Yeah, the balance is really good.

Yeah, they're surprisingly similar

to a normal javelin, actually. Yeah.

ATTENBOROUGH: Annemieke wants to test how

the spears fly, and if they can be

used accurately, to hit a target.

GARROD: We want to know,

can you two kill

that mammoth silhouette for us, please?

HUGHES: Okay, right, should we give it a go?

WALTON: Let's go.

(Garrod chortling) WALTON: Oh, my gosh.

First time.

♪ ♪

MILKS: Up until fairly recently,

most people were arguing that Neanderthals were

only capable of hunting at immediate distances.

And this shows that their technology

was capable of distance hunting.

(Garrod chortles) MILKS: Brilliant.

♪ ♪

GARROD: Okay, big question of the day.

Our site, is there any chance that our Neanderthals

could have been hunting mammoths, do you think?

Given the fact that we have a whole load of evidence

that the spears are functional weapons...

both as thrusting weapons and as throwing weapons...

and that we see this evidence

of exploitation of mammoth, I think it's very much

in the realm of possibility that mammoths were being

hunted by Neanderthals with spears like these.

♪ ♪

ATTENBOROUGH: So Neanderthals could possibly have hunted mammoths

at Cerney Wick over 200,000 years ago.

♪ ♪

But in the millennia that followed,

both the Neanderthals and the steppe mammoths disappeared.

♪ ♪

Neanderthals resettled in Britain around 60,000 years ago.

But our own species, Homo sapiens,

arrives soon after that,

and evidence of the presence of Neanderthals vanishes.

AL-SHAMAHI: It might be

that we out-competed them, right?

We were just better at using the landscape and resources.

One of the things that we know is that they

lived in small, isolated populations.

That is not going to do your gene pool any good. Hm.

At all.

There's even an argument

that they're still with us today.

Me and you will have about

two percent Neanderthal DNA in us.

And that's because our ancestors...

Multiple times, it seems...

interbred with Neanderthals.

So actually, the end of the story

isn't completely tragic,

because it turns out that there's a little bit of them...

Still here. In us, yeah.

ATTENBOROUGH: Back at the site at Cerney Wick,

there's excitement as they assess

their haul of flint tools.

(laughing): Are you okay? Are you okay?

Breathe... I think he forgot to breathe.

Wow, wow. This, this lovely little flake.

So you can see it's got a little point

where they hit it with a stone hammer to remove it.

WESTSCOTT WILKINS: It's perfect.

WILKINS: Wow, and that was the first hint that you found?

That was the first one, yeah. WILKINS: So there was a party straight after that?

And then the next one we found...

WILKINS: Oh, my goodness.

Is this beautiful scraper edge.

Typically we think, you know, you would have held it

like this. WESTSCOTT WILKINS: Look how it fits.

They would have pulled the fat off of the hide.

It's really quite impressive.

We've got these five flint tools all from the same area,

all finely worked, all really, really clear.

And that's quite exciting and quite rare.

I mean, it's really easy to say, "Oh, five things.

That's not many."

But actually, when we're talking about

200,000 years ago,

we might only be finding one or two things in a site

which has been excavated for decades.

ATTENBOROUGH: On the mammoth leg bone

they found next to the flints, they've seen scratch marks

that could provide evidence of butchery.

HOGUE: We see little marks and nicks...

WILKINS: Yeah. in the top.

HOGUE: Two lovely parallel lines.

There's one slightly longer. WILKINS: Yeah.

There's another one, just a short one, just in beside it. Yeah.

And it's really tempting to call them cut marks,

but we'll have to get it back into the lab

to actually determine. Yeah.

It's like a really big whodunit, isn't it? Mm-hmm.

So, did they all die of a disease?

Was there a massive flood that came in?

Or were we hunting them?

Having worked with elephants in the wild,

I think possibly, a juvenile, very, very young one

might have just got stuck in the mud.

It panicked the group.

Things went really badly really quickly,

and we came along as scavengers and possibly found

the world's biggest buffet lying there for us.

We're just opportunists, is what you're saying.

GARROD: I think we were opportunists.

HOGUE: Well, I just love the idea that the, you know,

Neanderthals are sitting on the ridge over the far end,

hiding amongst the tall grass.

And then mammoths are coming down

to the water and they're panicking them.

Neanderthals come in and they take advantage

of, of the mammoths, they sort of start butchering

and taking away the nice meat for meals.

GARROD: Isn't it wonderful to think that the last time

someone sat exactly on this spot

in a little group with that stone tool in their hands

was 200,000 years ago,

as a mammoth lying just over there? WILKINS: Wow.

And here we are talking about it...

Yeah, they were about to have their lunch.

...hundreds of thousands of years later. Yeah.

It's quite poignant, isn't it?

WILKINS: Yeah, absolutely. It really is.
