in one giant landmass that
stretches from pole to pole.

It is called, Pangaea.

Its climate is a blistering
20 degrees hotter than today

Growing over 10 feet long
and weighing over a tone,

87
00:07:33,244 --> 00:07:36,289
these bulky plant eaters
are reptiles

88

They’re slow,

90

Not far from our Gorgon family
the forces of nature are

A vast system of rifts
is reshaping the landscape.

Over thousands of years
pulses of volcanic activity

141
00:12:11,730 --> 00:12:13,858
have produced enough lava

142
00:12:14,484 --> 00:12:16,527
to cover the entire
United States

143
00:12:16,652 --> 00:12:20,156

a profound effect on life.

148

The vast amounts of carbon
dioxide being pumped out

149
00:12:46,265 --> 00:12:51,771
are sending atmospheric
temperatures soaring and forcing

150
00:12:51,938 --> 00:12:55,775
animals like our Gorgon
family to take extreme measures.

151
00:12:58,778 --> 00:13:01,155
The rising heat
is driving our alpha

00:13:01,280 --> 00:13:03,240
to keep migrating higher.

153
00:13:05,034 --> 00:13:08,370
For every 1,000 feet higher
he leads his family,

154
00:13:08,495 --> 00:13:11,457
the temperature drops
almost four degrees.

155
00:13:14,085 --> 00:13:16,629
It isn’t just the heat
that threatens them.

156
00:13:16,796 --> 00:13:20,466
Gases from the volcanoes
are destroying the Ozone layer,

157
00:13:21,092 --> 00:13:23,135
and this father wears
the damage of

158
00:13:23,260 --> 00:13:25,763
too much UV radiation
on his back.

159
00:13:35,815 --> 00:13:38,859
Eventually our family of
Gorgons reach somewhere

160
00:13:39,026 --> 00:13:40,903
higher and cooler to rest.

161
00:13:42,947 --> 00:13:47,326
But unlike the heat, one threat
has followed them up here.

162
00:13:49,078 --> 00:13:53,165
One that is focused exclusively
on our protective father.

He leads his family on,

363
00:30:32,288 --> 00:30:34,958
but there is nowhere left to go.

364
00:30:38,128 --> 00:30:42,715
Their world is doomed
and even he can’t save them.

[thunder rumbling]

366
00:30:48,471 --> 00:30:50,932
Eventually,
the northern eruptions

367
00:30:51,057 --> 00:30:53,726
will go on to release
more than 700 times

368
00:30:53,935 --> 00:30:55,520
more carbon dioxide

369
00:30:55,729 --> 00:30:59,357
than humans have produced
in our entire history.

370
00:31:03,611 --> 00:31:06,948
This extinction event
is the worst assault on life

371
00:31:07,073 --> 00:31:09,993
our planet has ever known.

372
00:31:12,162 --> 00:31:16,207
90% of all species
on Earth are wiped out.

373
00:31:18,626 --> 00:31:21,713
While this catastrophe makes
life impossible for most...

374
00:31:23,089 --> 00:31:26,885
a stubborn few species
manage to survive.

375
00:31:27,844 --> 00:31:33,683
[hopeful music playing]

376
00:31:39,647 --> 00:31:43,401
Close relatives of Elph
are among these survivors.

377
00:31:44,694 --> 00:31:46,905
By burrowing
and hibernating

378
00:31:47,030 --> 00:31:49,574
their kind withstand
everything the volcanoes

379
00:31:49,783 --> 00:31:53,036
can throw at them
and find ways to endure.

380
00:31:57,415 --> 00:31:59,000
This single event changes

381
00:31:59,209 --> 00:32:01,586
the entire direction
of evolution,

382
00:32:01,795 --> 00:32:04,380
as the few survivors
go on to establish

383
00:32:04,589 --> 00:32:07,842
all the animal dynasties
we know today.

384
00:32:11,637 --> 00:32:15,767
After 100,000 years
the volcanoes grow cold...

385
00:32:16,977 --> 00:32:20,271
but the world remains
a toxic wasteland.

386
00:32:21,898 --> 00:32:24,359
The atmosphere still
has carbon dioxide levels

387
00:32:24,484 --> 00:32:26,611
five times those of today.

388
00:32:32,117 --> 00:32:34,035
Millions of years pass,

389
00:32:34,202 --> 00:32:39,415
and slowly,
our wonderous planet heals.

390
00:32:42,418 --> 00:32:45,630
Helped by the most
lowly of the survivors...

391
00:32:46,714 --> 00:32:49,968
fungi, bacteria

392
00:32:50,135 --> 00:32:52,637
and photosynthetic algae.

393
00:32:58,726 --> 00:33:00,687
These tiny
life forms flourish in

394
00:33:00,854 --> 00:33:02,772
the carbon rich atmosphere

395
00:33:02,897 --> 00:33:06,776
and steadily consume
the excessive greenhouse gases.

396
00:33:10,780 --> 00:33:13,658
Earth finally begins to cool.

[distant growling]

399
00:33:32,177 --> 00:33:36,681
10 million years later,

400
00:33:36,890 --> 00:33:39,976
free of
its poisonous volcanic legacy,

401
00:33:40,101 --> 00:33:42,311
Earth is renewed.

402
00:33:43,938 --> 00:33:45,982
Our planet
can once again support

403
00:33:46,191 --> 00:33:48,526
a rich array of habitats.

404
00:33:52,321 --> 00:33:54,532
In this empty paradise,

405
00:33:54,699 --> 00:33:59,495
life begins to reclaim
every corner of the planet...

406
00:34:01,289 --> 00:34:06,044
sparking an extraordinary
explosion in evolution.

407

[dramatic instrumental]

408
00:34:19,056 --> 00:34:20,850
NARRATOR: 10 million
years have passed

409
00:34:20,975 --> 00:34:24,062
since the giant
northern eruptions fell silent.

410
00:34:25,521 --> 00:34:27,940
It’s taken this long
for the seas and forests

411
00:34:28,149 --> 00:34:29,692
to fully recover...

412
00:34:30,735 --> 00:34:33,237
and they are
teeming with life.

413
00:34:36,074 --> 00:34:38,076
On the shores of a shallow sea,

414
00:34:39,076 --> 00:34:41,037
the sand stirs.

415
00:34:43,081 --> 00:34:47,085
Eggs, laid months ago,
are hatching.

416
00:34:47,919 --> 00:34:50,046
[chirping softly]

417
00:34:50,213 --> 00:34:52,757
It is a baby Cyamodus...

418
00:34:54,676 --> 00:34:57,095
a new type of
hard-shelled reptile

419
00:34:57,554 --> 00:35:00,014
that has taken to
a life in the sea.

420
00:35:02,726 --> 00:35:04,602
They lay their eggs in the sand

421
00:35:04,811 --> 00:35:07,230
to protect them
from marine predators.

422
00:35:08,690 --> 00:35:12,401
[intense instrumental]

423
00:35:12,568 --> 00:35:15,738
But these days there
are predators everywhere.

[growling quietly]

425
00:35:23,705 --> 00:35:26,249
A female Dongusuchus.

426
00:35:26,958 --> 00:35:29,877
She’s a new type
of feathered reptile.

427
00:35:41,514 --> 00:35:44,517
She is being watched

428
00:35:44,642 --> 00:35:46,769
by another Dongusuchus.

429
00:35:50,482 --> 00:35:51,816
A male.

He’s not looking for lunch,
he’s looking...

432
00:35:57,655 --> 00:36:00,158
for a lunch date.

433
00:36:02,202 --> 00:36:05,037
With his bright plumage
and cool moves,

434
00:36:05,246 --> 00:36:08,166
he’s hoping to impress her.

435
00:36:11,878 --> 00:36:14,922
She’s not sure, yet.

436
00:36:19,427 --> 00:36:21,846
But he’s got more moves.

437
00:36:27,810 --> 00:36:29,896
New types of
gliding reptiles

438
00:36:30,105 --> 00:36:34,525
called proto-Pterosaurs,

[growling quietly]

The beach is getting busy.

441
00:36:44,077 --> 00:36:47,288
But our guy is not giving up
on his mating dance.

442

[soft, expansive music playing]

447

Cymbospondylus.

448
00:37:39,590 --> 00:37:42,677
A new type of
giant marine reptile...

449
00:37:43,678 --> 00:37:45,846
that will come
to dominate the seas

450
00:37:46,055 --> 00:37:50,059
for the next 157 million years.

[uplifting music playing]

452
00:37:56,357 --> 00:37:58,985
In the forests and mountains,

in the water and in the air

454
00:38:02,822 --> 00:38:06,367
it is the reptiles
that have seized the moment.

455
00:38:10,914 --> 00:38:14,458
If there is one point in
the history of life on Earth

456
00:38:14,667 --> 00:38:17,712
that sums up
its limitless resilience...

457
00:38:18,712 --> 00:38:20,965
this is it.

458
00:38:34,353 --> 00:38:36,814
Only two hundred years ago

459
00:38:36,939 --> 00:38:40,276
Earth had some of the lowest
carbon dioxide levels

460
00:38:40,818 --> 00:38:42,820
that have ever existed.

they have risen by
over 50 percent.

[car horns honking]

465
00:39:07,637 --> 00:39:11,057
Compared with
the history of life on Earth,

466
00:39:11,182 --> 00:39:15,311
today’s levels of carbon
dioxide are still not high...

467
00:39:19,773 --> 00:39:22,026
but it is
the speed of the change

468
00:39:22,235 --> 00:39:25,363
that is challenging
all living things.

469
00:39:34,205 --> 00:39:37,041
Recently,
action has been taken.

470
00:39:40,545 --> 00:39:44,465
In the next few years,
emissions could stop rising...

471
00:39:46,968 --> 00:39:48,886
but the extra greenhouse gases

472
00:39:49,011 --> 00:39:52,932
will remain in
our atmosphere for decades,

473
00:39:53,141 --> 00:39:55,559
possibly even centuries.

474
00:40:00,148 --> 00:40:01,857
If these levels are to drop,

475
00:40:01,982 --> 00:40:04,402
the key will lie in
our planet’s ability

476
00:40:04,569 --> 00:40:06,904
to absorb carbon dioxide.

477
00:40:11,367 --> 00:40:14,662
In our peat bogs
and sea grass meadows...

00:40:18,916 --> 00:40:21,335
Nature already has
the best tools

00:40:21,544 --> 00:40:24,213
to turn the tide
on greenhouse gases.

Protecting
and bolstering these habitats

482
00:40:29,635 --> 00:40:31,429
is the next great challenge

483
00:40:31,888 --> 00:40:34,515
