NARRATOR:
Earth, a breathtaking planet

00:00:11,240 --> 00:00:15,202
that has supported life
for billions of years.

[energetic music playing]
4
00:00:18,998 --> 00:00:22,043
But it can be a challenging
and cruel home.

[thunder rumbling]
6
00:00:25,713 --> 00:00:29,884
From the beginning, creatures
have had to be tough to survive.
7
00:00:30,635 --> 00:00:32,219
[loud roar]
8
00:00:32,428 --> 00:00:36,348
Mass extinctions
wiped out entire species.
9
00:00:38,433 --> 00:00:41,896
From super volcanoes
to an asteroid apocalypse.
10
00:00:42,480 --> 00:00:44,106
[wind howling]
11
00:00:45,149 --> 00:00:49,904
From megafloods to a frozen
planet strangled by darkness
12
00:00:52,282 --> 00:00:55,993
With every disaster,
there was suffering,
13
00:00:57,537 --> 00:01:00,539
but each time life returned...
14
00:01:02,541 --> 00:01:04,335
even stronger.
15
00:01:07,255 --> 00:01:11,550
Witness the heart
and the hope of our planet.
16
00:01:15,554 --> 00:01:20,101
Travel back in time to see
how life fights back...
17
00:01:23,104 --> 00:01:24,855
and wins.
18
00:01:26,232 --> 00:01:30,236

[ethereal music playing]
20
00:01:54,302 --> 00:01:57,263
NARRATOR:
252 million years ago.
21
00:01:58,097 --> 00:02:01,851
At this time all our planet’s
continents are fused together
22
00:02:01,976 --> 00:02:06,313
in one giant landmass that
stretches from pole to pole.
23
00:02:08,107 --> 00:02:10,818
It is called, Pangaea.
24
00:02:13,404 --> 00:02:17,366
Its climate is a blistering
20 degrees hotter than today
25
00:02:17,783 --> 00:02:21,787
and its vast heartlands are
dominated by endless deserts.
26
00:02:22,955 --> 00:02:27,668
Life clings on here
but it is not an easy existence.
27
00:02:31,797 --> 00:02:34,717
And something is about to happen
28
00:02:34,926 --> 00:02:36,969
that will make it everything
29
00:02:37,136 --> 00:02:39,013
-much worse.
-[loud explosion]
30
00:02:41,808 --> 00:02:44,810
[bright music playing]
31
00:02:44,977 --> 00:02:46,854
Not all of Pangaea is barren.
32
00:02:47,730 --> 00:02:49,356
Towards both poles
33
00:02:49,523 --> 00:02:52,193
the temperatures are cooler
and forests grow.
34
00:02:54,362 --> 00:02:56,864
Conifers cover
these northern hills.
35
00:02:57,948 --> 00:02:59,700
[bird squawks]
36
00:02:59,825 --> 00:03:04,371
And, beneath their branches
life thrives.
37
00:03:05,956 --> 00:03:08,334
[soft roar]
38
00:03:09,710 --> 00:03:11,879
A young Gorgonopsian...
39
00:03:13,714 --> 00:03:15,466
on a mission...
40
00:03:24,851 --> 00:03:26,894
to irritate his brother.
41
00:03:29,897 --> 00:03:31,941
[soft growling]
42
00:03:32,108 --> 00:03:35,903
Oh well, how about a sneak
attack on his mother.
43
00:03:38,781 --> 00:03:42,493
These Gorgons are early,
distant relatives of mammals...
44
00:03:47,248 --> 00:03:48,791
and, long before the dinosaurs,
45
00:03:49,000 --> 00:03:51,252
[loud yawns]
46
00:03:51,461 --> 00:03:54,755
this is what an apex
predator looks like.
47
00:04:00,386 --> 00:04:03,597
In this world,
the only thing a Gorgon fears...
48
00:04:04,640 --> 00:04:06,183
is another Gorgon.
49
00:04:06,392 --> 00:04:07,768
[tense music playing]
50
00:04:07,935 --> 00:04:11,105

[loud roar]
52
00:04:31,208 --> 00:04:35,921
Bigger than a tiger, this
alpha bears the battle scars
53
00:04:36,130 --> 00:04:38,966
from years of defending
his position
54
00:04:41,469 --> 00:04:43,637
as leader of this family.
55
00:04:43,762 --> 00:04:46,974
[soft, enchanting music playing]
56
00:04:50,769 --> 00:04:53,480
He has fathered generations
of young Gorgons
57
00:04:54,231 --> 00:04:56,817
with this group of
three different mothers.
58
00:05:03,782 --> 00:05:05,993
In this overheated world,
59
00:05:06,202 --> 00:05:09,246
he has led his family up from
the baking plains
60
00:05:09,455 --> 00:05:12,249
to find food and shade
among these foothills.
61
00:05:14,460 --> 00:05:16,337
[tense music playing]
62
00:05:19,507 --> 00:05:21,217
[soft growling]
63
00:05:21,926 --> 00:05:24,595
But now, he smells trouble.
64
00:05:27,389 --> 00:05:32,603
Skulking in the shadows
a lone, younger male.
65
00:05:34,104 --> 00:05:36,357
These are his woods.
66
00:05:40,194 --> 00:05:44,031
Males will fight to the death
for the right to mate.
67
00:05:49,244 --> 00:05:51,163
This one is waiting to see
68
00:05:51,372 --> 00:05:55,667
if the old alpha shows
any signs of weakness.
69
00:06:05,511 --> 00:06:07,971
Not all creatures in
these northern forests
70
00:06:08,138 --> 00:06:10,224
survive by being aggressive.
71
00:06:10,349 --> 00:06:12,976
[shrieks]
72
00:06:13,894 --> 00:06:20,067
Some, like this burrowing Elph,
have to rely on their wits.
73
00:06:21,735 --> 00:06:23,195
[soft growling]
74
00:06:26,949 --> 00:06:29,410
Playing dead is one trick.
75
00:06:30,536 --> 00:06:32,496
[sniffs]
76
00:06:39,295 --> 00:06:40,879
It’s a good performance...
77
00:06:41,755 --> 00:06:43,549
if he can just hold on...
78
00:06:49,555 --> 00:06:51,056
-[shrieks]
-[dramatic music playing]
79
00:06:51,265 --> 00:06:52,766
Too late.

[tense music playing]
83
00:07:12,953 --> 00:07:16,748
Our young Gorgon
has run straight into a giant.
84
00:07:20,294 --> 00:07:22,296
A whole herd of them...
85
00:07:26,050 --> 00:07:27,634
Scutosaurus.
86
00:07:29,720 --> 00:07:33,056
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
00:07:36,477 --> 00:07:38,770
and some of the largest
creatures on Earth.
89
00:07:43,066 --> 00:07:44,443
They’re slow,
90
00:07:45,069 --> 00:07:49,615
but with creatures this size
he could easily be crushed.
91
00:07:52,534 --> 00:07:55,787
His frantic mum has only
now realized he’s missing.
92
00:07:55,912 --> 00:07:59,583
[Gorgon calling]
93
00:08:01,627 --> 00:08:06,340
As long as they remain calm
our little guy should be safe.
94
00:08:10,969 --> 00:08:14,223
But, across the plains below,
trouble is brewing.
95
00:08:14,390 --> 00:08:16,141
[thunder rumbling]
96
00:08:16,308 --> 00:08:18,810
The herd can sense it
and a thunderstorm.
97
00:08:19,603 --> 00:08:21,855
And they are getting restless.
98
00:08:22,355 --> 00:08:23,857
[thunder rumbling]
99
00:08:24,066 --> 00:08:26,485
Up here in the mountains,
lightning strikes are common.
100
00:08:29,071 --> 00:08:31,990
None of which is good
news for our youngster.
101
00:08:40,916 --> 00:08:44,086
NARRATOR:
252 million years before
102
00:08:44,211 --> 00:08:46,296
modern humans walked the Earth,
103
00:08:47,756 --> 00:08:49,716
all the continents are fused
104
00:08:49,841 --> 00:08:52,886
as one giant landmass
called Pangea.
105
00:08:54,763 --> 00:08:56,974
It is a dry desolate place,
106
00:09:00,436 --> 00:09:01,812
except at the poles
107
00:09:01,979 --> 00:09:04,231
where lush conifer
forests grow.
108
00:09:09,278 --> 00:09:11,071
[thunder rumbling]
109
00:09:11,196 --> 00:09:15,909
Here a sudden storm has spooked
a herd of giant Scutosaurus.
110
00:09:16,076 --> 00:09:18,078
[growling]
111
00:09:19,413 --> 00:09:22,749
Caught in the middle
is our young Gorgon.
112
00:09:23,959 --> 00:09:27,045
One wrong step
and he will be crushed to death.
113
00:09:32,885 --> 00:09:35,387
[dramatic music playing]
114
00:09:35,512 --> 00:09:37,598
[Gorgons calling]
115
00:09:43,020 --> 00:09:45,439
His panicked mom needs
to find him.
116
00:09:48,567 --> 00:09:50,611
[baby Gorgon calling]
117
00:09:50,778 --> 00:09:53,822
She spots him
and her every instinct is
118
00:09:53,989 --> 00:09:56,617
to save her son at all cost.
119
00:09:58,076 --> 00:10:00,203
[dramatic music playing]
120
00:10:13,926 --> 00:10:16,470
[Gorgon squeeze, cries]
121
00:10:27,105 --> 00:10:29,149
[nostalgic music playing]
122
00:10:30,734 --> 00:10:33,904
Our mother succeeded in
protecting her little one.
123
00:10:37,032 --> 00:10:41,161
But, in doing so,
she made the ultimate sacrifice.
124
00:10:44,206 --> 00:10:45,957
He doesn’t want to leave
her side.
125
00:10:46,124 --> 00:10:47,626
[cries]
126
00:10:47,751 --> 00:10:51,713
[loud growling]
127
00:10:51,880 --> 00:10:54,841
But his father’s call
echoes through the forest.
128
00:11:00,973 --> 00:11:04,685
The old alpha leads the family
away from the panicked herd.
129
00:11:19,533 --> 00:11:23,620
After the storm,
the sun sets and the sky flares
130
00:11:23,787 --> 00:11:25,872
a spectacular blood red.
131
00:11:27,791 --> 00:11:29,376
It’s an ominous sign.
132
00:11:31,795 --> 00:11:36,007
Not far from our Gorgon family
the forces of nature are
133
00:11:36,174 --> 00:11:39,886
about to put on a show that will
bring all life to its knees.
134
00:11:42,013 --> 00:11:44,266
The mighty continent of Pangaea,
135
00:11:44,933 --> 00:11:47,853
the world’s single
landmass that has shaped life
136
00:11:47,978 --> 00:11:49,813
for almost 50 million years
137
00:11:51,607 --> 00:11:53,024
is being torn apart.
138
00:11:54,860 --> 00:11:56,528
[dramatic music playing]
139
00:11:56,653 --> 00:12:00,073
A vast system of rifts
is reshaping the landscape.
140
00:12:06,997 --> 00:12:11,209
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
Now, all the side to the rift
145
00:12:25,891 --> 00:12:29,436
is ramping up
for its biggest eruption yet.
146
00:12:35,985 --> 00:12:38,695
Emissions from these
volcanoes are already having
147
00:12:38,820 --> 00:12:40,739
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.
163
00:13:54,104 --> 00:13:59,192
The desperate lone rival has
been shadowing his every step
164
00:14:00,485 --> 00:14:04,698
waiting for the right time
to strike.
165
00:14:10,746 --> 00:14:12,622
NARRATOR: Dawn breaks
across the northern hills
166
00:14:12,789 --> 00:14:15,792
on the hot dry continent
of Pangea.
167
00:14:17,335 --> 00:14:19,838
The one giant landmass
on our planet.
168
00:14:21,005 --> 00:14:22,966
Volcanic activity
is making an already
169
00:14:23,133 --> 00:14:25,343
stifling world even hotter.
170
00:14:27,304 --> 00:14:29,055
To find cooler temperatures
171
00:14:29,222 --> 00:14:32,058
our Gorgon family has
climbed higher into the hills.
172
00:14:37,523 --> 00:14:40,150
They wake
in unfamiliar surroundings
173
00:14:40,317 --> 00:14:42,027
and they are starving.
174
00:14:42,944 --> 00:14:44,905
None have eaten in days....

[Suminia squeaks]
176
00:14:48,408 --> 00:14:53,079
But just when they need it most,
a small meal appears.

[Suminia squeaks]
179
00:15:05,801 --> 00:15:08,553
This should be no contest
for our hungry alpha.

00:30:19,422 --> 00:30:21,173
the old alpha has won.
361
00:30:21,382 --> 00:30:23,425
[growling quietly]
362
00:30:29,682 --> 00:30:32,226
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.
365
00:30:42,861 --> 00:30:45,364
[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.
397
00:33:18,642 --> 00:33:23,981
[soft, hopeful music playing]
398
00:33:27,568 --> 00:33:32,031
[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
00:34:06,232 --> 00:34:09,568
[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.
424
00:35:21,014 --> 00:35:23,559
[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.
430
00:35:52,004 --> 00:35:54,298
[growling quietly]
431
00:35:54,465 --> 00:35:57,509
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,
head for the sand.
439
00:36:36,548 --> 00:36:37,841
[growling quietly]
440
00:36:39,009 --> 00:36:41,011
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
00:36:52,397 --> 00:36:54,566
Time to pull out all the stops.
443
00:36:59,071 --> 00:37:02,407
[growling quietly]
444
00:37:03,575 --> 00:37:06,370
-[roaring]
-[Dongusuchus squawking]
445
00:37:17,047 --> 00:37:20,509
Well, someone really
didn’t like his dancing.
446
00:37:23,262 --> 00:37:28,350
[soft, expansive music playing]
447
00:37:33,855 --> 00:37:35,941
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.
451
00:37:53,125 --> 00:37:56,211
[uplifting music playing]
452
00:37:56,378 --> 00:37:59,006
In the forests and mountains,
453
00:37:59,215 --> 00:38:02,009
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.
461
00:38:46,052 --> 00:38:51,058
[insects chirping]
462
00:38:51,267 --> 00:38:54,061
But since
the Industrial Revolution
463
00:38:54,186 --> 00:38:57,022
they have risen by
over 50 percent.
464
00:38:57,231 --> 00:39:00,859
[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...
478
00:40:15,809 --> 00:40:18,186
oceans and forests.
479
00:40:18,937 --> 00:40:21,356
Nature already has
the best tools
480
00:40:21,565 --> 00:40:24,234
to turn the tide
on greenhouse gases.
481
00:40:26,987 --> 00:40:29,489
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
in the fight against
global warming.
