At this time all our planet’s

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
00:07:33,265 --> 00:07:36,310
these bulky plant eaters
are reptiles

88

and some of the largest
creatures on Earth.

They’re slow,

90

Not far from our Gorgon family
the forces of nature are

A vast system of rifts
is reshaping the landscape.

140

Over thousands of years
pulses of volcanic activity

141
00:12:11,751 --> 00:12:13,879
have produced enough lava

142
00:12:14,505 --> 00:12:16,548
to cover the entire
United States

143
00:12:16,673 --> 00:12:20,177
in molten rock half a mile deep.

144
00:12:23,054 --> 00:12:25,724

a profound effect on life.

148
00:12:43,200 --> 00:12:46,119
The vast amounts of carbon
dioxide being pumped out

149
00:12:46,286 --> 00:12:51,792
are sending atmospheric
temperatures soaring and forcing

150
00:12:51,959 --> 00:12:55,796
animals like our Gorgon
family to take extreme measures.

151
00:12:58,799 --> 00:13:01,176
The rising heat
is driving our alpha

152
00:13:01,301 --> 00:13:03,261
to keep migrating higher.

153
00:13:05,055 --> 00:13:08,391
For every 1,000 feet higher
he leads his family,

154
00:13:08,516 --> 00:13:11,478
the temperature drops
almost four degrees.

155
00:13:14,106 --> 00:13:16,650
It isn’t just the heat
that threatens them.

156
00:13:16,817 --> 00:13:20,487
Gases from the volcanoes
are destroying the Ozone layer,

157
00:13:21,113 --> 00:13:23,156
and this father wears
the damage of

158
00:13:23,281 --> 00:13:25,784
too much UV radiation
on his back.

159
00:13:35,836 --> 00:13:38,880
Eventually our family of
Gorgons reach somewhere

160
00:13:39,047 --> 00:13:40,924
higher and cooler to rest.

161
00:13:42,968 --> 00:13:47,347
But unlike the heat, one threat
has followed them up here.

162
00:13:49,099 --> 00:13:53,186
One that is focused exclusively
on our protective father.

He leads his family on,

363
00:30:32,309 --> 00:30:34,979
but there is nowhere left to go.

364
00:30:38,149 --> 00:30:42,736
Their world is doomed
and even he can’t save them.

[thunder rumbling]

366
00:30:48,492 --> 00:30:50,953
Eventually,
the northern eruptions

367
00:30:51,078 --> 00:30:53,747
will go on to release
more than 700 times

368
00:30:53,956 --> 00:30:55,541
more carbon dioxide

369
00:30:55,750 --> 00:30:59,378
than humans have produced
in our entire history.

370
00:31:03,632 --> 00:31:06,969
This extinction event
is the worst assault on life

371
00:31:07,094 --> 00:31:10,014
our planet has ever known.

372
00:31:12,183 --> 00:31:16,228
90% of all species
on Earth are wiped out.

373
00:31:18,647 --> 00:31:21,734
While this catastrophe makes
life impossible for most...

374
00:31:23,110 --> 00:31:26,906
a stubborn few species
manage to survive.

375
00:31:27,865 --> 00:31:33,704
[hopeful music playing]

376
00:31:39,668 --> 00:31:43,422
Close relatives of Elph
are among these survivors.

377
00:31:44,715 --> 00:31:46,926
By burrowing
and hibernating

378
00:31:47,051 --> 00:31:49,595
their kind withstand
everything the volcanoes

379
00:31:49,804 --> 00:31:53,057
can throw at them
and find ways to endure.

380
00:31:57,436 --> 00:31:59,021
This single event changes

381
00:31:59,230 --> 00:32:01,607
the entire direction
of evolution,

382
00:32:01,816 --> 00:32:04,401
as the few survivors
go on to establish

383
00:32:04,610 --> 00:32:07,863
all the animal dynasties
we know today.

384
00:32:11,658 --> 00:32:15,788
After 100,000 years
the volcanoes grow cold...

385
00:32:16,998 --> 00:32:20,292
but the world remains
a toxic wasteland.

386
00:32:21,919 --> 00:32:24,380
The atmosphere still
has carbon dioxide levels

387
00:32:24,505 --> 00:32:26,632
five times those of today.

388
00:32:32,138 --> 00:32:34,056
Millions of years pass,

389
00:32:34,223 --> 00:32:39,436
and slowly,
our wonderous planet heals.

390
00:32:42,439 --> 00:32:45,651
Helped by the most
lowly of the survivors...

391
00:32:46,735 --> 00:32:49,989
fungi, bacteria

392
00:32:50,156 --> 00:32:52,658
and photosynthetic algae.

393
00:32:58,747 --> 00:33:00,708
These tiny
life forms flourish in

394
00:33:00,875 --> 00:33:02,793
the carbon rich atmosphere

395
00:33:02,918 --> 00:33:06,797
and steadily consume
the excessive greenhouse gases.

396
00:33:10,801 --> 00:33:13,679
Earth finally begins to cool.

[distant growling]

399
00:33:32,198 --> 00:33:36,702
10 million years later,

400
00:33:36,911 --> 00:33:39,997
free of
its poisonous volcanic legacy,

401
00:33:40,122 --> 00:33:42,332
Earth is renewed.

402
00:33:43,959 --> 00:33:46,003
Our planet
can once again support

403
00:33:46,212 --> 00:33:48,547
a rich array of habitats.

404
00:33:52,342 --> 00:33:54,553
In this empty paradise,

405
00:33:54,720 --> 00:33:59,516
life begins to reclaim
every corner of the planet...

406
00:34:01,310 --> 00:34:06,065
sparking an extraordinary
explosion in evolution.

407

[dramatic instrumental]

408
00:34:19,077 --> 00:34:20,871
NARRATOR: 10 million
years have passed

409
00:34:20,996 --> 00:34:24,083
since the giant
northern eruptions fell silent.

410
00:34:25,542 --> 00:34:27,961
It’s taken this long
for the seas and forests

411
00:34:28,170 --> 00:34:29,713
to fully recover...

412
00:34:30,756 --> 00:34:33,258
and they are
teeming with life.

413
00:34:36,095 --> 00:34:38,097
On the shores of a shallow sea,

414
00:34:39,097 --> 00:34:41,058
the sand stirs.

415
00:34:43,102 --> 00:34:47,106
Eggs, laid months ago,
are hatching.

416
00:34:47,940 --> 00:34:50,067
[chirping softly]

417
00:34:50,234 --> 00:34:52,778
It is a baby Cyamodus...

418
00:34:54,697 --> 00:34:57,116
a new type of
hard-shelled reptile

419
00:34:57,575 --> 00:35:00,035
that has taken to
a life in the sea.

420
00:35:02,747 --> 00:35:04,623
They lay their eggs in the sand

421
00:35:04,832 --> 00:35:07,251
to protect them
from marine predators.

422
00:35:08,711 --> 00:35:12,422
[intense instrumental]

423
00:35:12,589 --> 00:35:15,759
But these days there
are predators everywhere.

[growling quietly]

425
00:35:23,726 --> 00:35:26,270
A female Dongusuchus.

426
00:35:26,979 --> 00:35:29,898
She’s a new type
of feathered reptile.

427
00:35:41,535 --> 00:35:44,538
She is being watched

428
00:35:44,663 --> 00:35:46,790
by another Dongusuchus.

429
00:35:50,503 --> 00:35:51,837
A male.

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

432
00:35:57,676 --> 00:36:00,179
for a lunch date.

433
00:36:02,223 --> 00:36:05,058
With his bright plumage
and cool moves,

434
00:36:05,267 --> 00:36:08,187
he’s hoping to impress her.

435
00:36:11,899 --> 00:36:14,943
She’s not sure, yet.

436
00:36:19,448 --> 00:36:21,867
But he’s got more moves.

437
00:36:27,831 --> 00:36:29,917
New types of
gliding reptiles

438
00:36:30,126 --> 00:36:34,546
called proto-Pterosaurs,

[growling quietly]

The beach is getting busy.

441
00:36:44,098 --> 00:36:47,309
But our guy is not giving up
on his mating dance.

442

[soft, expansive music playing]

447

Cymbospondylus.

448
00:37:39,611 --> 00:37:42,698
A new type of
giant marine reptile...

449
00:37:43,699 --> 00:37:45,867
that will come
to dominate the seas

450
00:37:46,076 --> 00:37:50,080
for the next 157 million years.

[uplifting music playing]

452
00:37:56,378 --> 00:37:59,006
In the forests and mountains,

in the water and in the air

454
00:38:02,843 --> 00:38:06,388
it is the reptiles
that have seized the moment.

455
00:38:10,935 --> 00:38:14,479
If there is one point in
the history of life on Earth

456
00:38:14,688 --> 00:38:17,733
that sums up
its limitless resilience...

457
00:38:18,733 --> 00:38:20,986
this is it.

458
00:38:34,374 --> 00:38:36,835
Only two hundred years ago

459
00:38:36,960 --> 00:38:40,297
Earth had some of the lowest
carbon dioxide levels

460
00:38:40,839 --> 00:38:42,841
that have ever existed.

they have risen by
over 50 percent.

[car horns honking]

465
00:39:07,658 --> 00:39:11,078
Compared with
the history of life on Earth,

466
00:39:11,203 --> 00:39:15,332
today’s levels of carbon
dioxide are still not high...

467
00:39:19,794 --> 00:39:22,047
but it is
the speed of the change

468
00:39:22,256 --> 00:39:25,384
that is challenging
all living things.

469
00:39:34,226 --> 00:39:37,062
Recently,
action has been taken.

470
00:39:40,566 --> 00:39:44,486
In the next few years,
emissions could stop rising...

471
00:39:46,989 --> 00:39:48,907
but the extra greenhouse gases

472
00:39:49,032 --> 00:39:52,953
will remain in
our atmosphere for decades,

473
00:39:53,162 --> 00:39:55,580
possibly even centuries.

474
00:40:00,169 --> 00:40:01,878
If these levels are to drop,

475
00:40:02,003 --> 00:40:04,423
the key will lie in
our planet’s ability

476
00:40:04,590 --> 00:40:06,925
to absorb carbon dioxide.

477
00:40:11,388 --> 00:40:14,683
In our peat bogs
and sea grass meadows...

Nature already has
the best tools

00:40:21,565 --> 00:40:24,234
to turn the tide
on greenhouse gases.

Protecting
and bolstering these habitats

482
00:40:29,656 --> 00:40:31,450
is the next great challenge

483
00:40:31,909 --> 00:40:34,536
