to know the torment of hunger. 4 00:00:36,253 --> 00:00:39,303 There was once a man who dreamed that through science, 5 00:00:39,778 --> 00:00:42,958 we could make a world where no one would ever perish from hunger. 6 00:00:43,130 --> 00:00:45,610 And famine would be no more. 7 00:00:45,784 --> 00:00:48,614 He gave us a treasure to fulfil that promise, 8 00:00:48,787 --> 00:00:51,657 but he faced a terrible choice at a moment of reckoning. 9 00:00:52,313 --> 00:00:54,843 To lie about science and live, 10 00:00:55,011 --> 00:00:58,621 or to tell the truth and face certain death. 11 00:01:00,060 --> 00:01:05,540 [theme music plays] 12 00:01:24,867 --> 00:01:31,267 ♪ ♪ 13 00:01:50,240 --> 00:01:55,900 ♪ ♪ 14 00:02:10,217 --> 00:02:12,827 TYSON: For the first couple of hundred thousand years that 15 00:02:13,002 --> 00:02:16,442 we were human, we were wanderers living beneath the stars. 16 00:02:17,702 --> 00:02:20,052 We gathered plant life and hunted animals. 17 00:02:20,749 --> 00:02:23,529 Until about ten or 12,000 years ago, 18 00:02:24,013 --> 00:02:26,893 when our ancestors invented a new way to live. 19 00:02:27,886 --> 00:02:31,186 Think of those geniuses who were the first to realize that 20 00:02:31,368 --> 00:02:33,758 inside the plants they foraged, 21 00:02:33,936 --> 00:02:36,026 was a means to make another plant. 22 00:02:37,069 --> 00:02:39,249 A seed. 23 00:02:40,769 --> 00:02:43,549 [thunder] 24 00:02:43,728 --> 00:02:46,118 [rain] 25 00:02:46,862 --> 00:02:51,172 That discovery led to the single most fateful choice our species ever made. 26 00:02:52,520 --> 00:02:55,220 They could continue to wander in small bands, 27 00:02:55,697 --> 00:02:58,737 or they could settle down to grow and raise their food. 28 00:02:59,570 --> 00:03:03,710 This required sacrifices for rewards that would not come until much later. 29 00:03:05,141 --> 00:03:08,451 For the first time, we were thinking about the future. 30 00:03:12,453 --> 00:03:14,633 Of course, these decisions weren't made in an instant. 31 00:03:15,412 --> 00:03:17,852 They unfolded over generations. 32 00:03:18,154 --> 00:03:20,774 That seems like a long time ago in human terms, 33 00:03:21,331 --> 00:03:23,641 but in the great sweep of cosmic time, 34 00:03:23,812 --> 00:03:26,212 it was less than a half a minute ago. 35 00:03:27,598 --> 00:03:31,818 This Cosmic Calendar compresses all of the last 13.8 billion years 36 00:03:32,690 --> 00:03:35,780 since the big bang into a single calendar Earth year. 37 00:03:36,433 --> 00:03:39,963 Midnight on December 31 is right now. 38 00:03:40,785 --> 00:03:44,345 Every month is a little more than a billion years. 39 00:03:45,225 --> 00:03:48,395 Every day, a little less than 40 million years. 40 00:03:49,011 --> 00:03:52,751 And all of humanity's proudest achievements unfold 41 00:03:52,928 --> 00:03:55,968 in the last couple of minutes of cosmic time. 42 00:03:56,758 --> 00:03:59,328 That's how new we are to the universe. 43 00:04:01,284 --> 00:04:04,034 Our ancestors began to domesticate animals and 44 00:04:04,200 --> 00:04:07,640 plants less than 30 seconds ago on the Cosmic Calendar. 45 00:04:08,683 --> 00:04:11,773 For the first time, the wanderers were settling down. 46 00:04:12,774 --> 00:04:15,914 And building things to last for more than a single season. 47 00:04:16,821 --> 00:04:19,221 They dared to touch the future. 48 00:04:20,347 --> 00:04:23,177 Their tower of Jericho still stands. 49 00:04:23,611 --> 00:04:26,181 Was it a watchtower for protecting the city from invaders? 50 00:04:27,049 --> 00:04:29,399 Or just a way to get closer to the stars? 51 00:04:31,053 --> 00:04:34,143 It took 11,000 work days to build. 52 00:04:35,057 --> 00:04:36,797 Something that could only be possible with the 53 00:04:36,972 --> 00:04:39,842 food surpluses that agriculture provided. 54 00:04:42,064 --> 00:04:44,724 This is the world's oldest stairway. 55 00:04:45,807 --> 00:04:51,987 It was already 5,000 years old before the first Egyptian pyramid was built. 56 00:04:52,161 --> 00:04:56,341 To climb it is to follow in the footsteps of 300 generations. 57 00:04:58,428 --> 00:05:02,428 Isn't it astonishing that people who had barely ceased wandering, 58 00:05:02,606 --> 00:05:05,476 we're able to create something of such permanence? 59 00:05:13,617 --> 00:05:16,267 The rich and varied hunter-gatherer diet, 60 00:05:16,446 --> 00:05:19,446 of plants, insects, birds and other animals, was replaced. 61 00:05:21,190 --> 00:05:25,150 City dwellers largely subsisted on a few carbohydrate crops. 62 00:05:25,977 --> 00:05:28,937 And when the rains didn't come or a fungus afflicted the grain, 63 00:05:29,894 --> 00:05:32,384 there was hunger on a massive scale. 64 00:05:32,549 --> 00:05:34,379 Famine. 65 00:05:36,640 --> 00:05:40,820 Famines caused by drought and British colonial mismanagement 66 00:05:41,341 --> 00:05:45,261 in India in the 18th century killed ten million people. 67 00:05:46,433 --> 00:05:48,913 In China, during the famines of the 19th century, 68 00:05:49,784 --> 00:05:52,664 more than 100 million people perished. 69 00:05:53,831 --> 00:05:55,921 The great hunger in Ireland, 70 00:05:56,094 --> 00:05:58,454 also a result of British imperial policy, 71 00:05:58,619 --> 00:06:00,749 starved a million to death and 72 00:06:00,925 --> 00:06:04,405 forced another two million to flee the country in search of a living. 73 00:06:05,408 --> 00:06:10,148 The Brazilian drought and pestilence of 1877 was comparable. 74 00:06:10,500 --> 00:06:14,370 In a single province, more than half died of starvation. 75 00:06:14,939 --> 00:06:18,249 The dead remain uncounted from the famines that wracked 76 00:06:18,421 --> 00:06:22,381 Ethiopia, Rwanda and the Sahel in Africa. 77 00:06:23,731 --> 00:06:25,911 For a couple of thousand years, 78 00:06:26,081 --> 00:06:29,951 ever since records were kept, somewhere on Earth, 79 00:06:30,128 --> 00:06:32,908 people in great numbers have starved. 80 00:06:37,353 --> 00:06:41,883 Could agriculture become a science with a predictive theory as reliable as gravity? 81 00:06:43,141 --> 00:06:47,841 One that could consistently produce breeds able to stand up to drought and disease? 82 00:06:49,104 --> 00:06:52,374 Farmers and herders knew the advantages of preferentially 83 00:06:52,542 --> 00:06:55,632 selecting the hardiest specimens for crossbreeding, 84 00:06:55,806 --> 00:06:58,326 to produce a more successful hybrid. 85 00:06:58,505 --> 00:07:00,805 This was known as artificial selection. 86 00:07:01,812 --> 00:07:04,382 But the mechanism of how those traits were passed on to 87 00:07:04,554 --> 00:07:07,954 succeeding generations remained a complete mystery. 88 00:07:09,646 --> 00:07:12,036 This is Down House. 89 00:07:12,344 --> 00:07:14,614 Charles Darwin's home, where he lived with his wife 90 00:07:14,782 --> 00:07:17,182 Emma and their ten children. 91 00:07:17,349 --> 00:07:20,349 He was hardly the authoritarian Victorian patriarch. 92 00:07:20,918 --> 00:07:24,008 But instead a tender, loving father who delighted 93 00:07:24,182 --> 00:07:25,972 in his children's ridicule. 94 00:07:27,969 --> 00:07:30,279 This is the garden he planted. 95 00:07:31,102 --> 00:07:34,452 This place is a strangely pastoral setting for the most 96 00:07:34,628 --> 00:07:37,458 influential revolutionary in the history of thought. 97 00:07:39,067 --> 00:07:43,197 Even now, there are people who are afraid of his idea. 98 00:07:48,293 --> 00:07:51,433 Charles Darwin discovered that species, including ours, 99 00:07:52,254 --> 00:07:55,614 evolve over time through a process of natural selection. 100 00:07:56,388 --> 00:07:59,168 The environment rewards those best adapted to its changing 101 00:07:59,348 --> 00:08:03,828 realities with survival and with new generations of offspring. 102 00:08:04,353 --> 00:08:08,053 Darwin demystified the external reality of life, 103 00:08:08,836 --> 00:08:12,966 but no one had any idea what the inner mechanisms of evolution were. 104 00:08:15,538 --> 00:08:17,978 At that same moment, an abbot at a rural monastery 105 00:08:18,933 --> 00:08:23,373 in what is now the Czech Republic was trying to become a science professor. 106 00:08:24,068 --> 00:08:27,678 Gregor Mendel flunked his qualifying exam both times. 107 00:08:28,551 --> 00:08:32,161 The only career path open to him was to become a substitute teacher. 108 00:08:32,990 --> 00:08:34,340 So in his spare time, 109 00:08:34,514 --> 00:08:36,694 he took up the study of pea plants. 110 00:08:38,213 --> 00:08:40,433 He bred tens of thousands of them, 111 00:08:40,607 --> 00:08:42,997 carefully scrutinizing their height and their shape 112 00:08:43,653 --> 00:08:46,403 and the color of their pods, their seeds and flowers. 113 00:08:48,571 --> 00:08:51,841 Mendel was searching for a predictive theory of breeding. 114 00:08:52,009 --> 00:08:54,799 So that you could know in advance exactly what you would 115 00:08:54,969 --> 00:08:58,059 get when you crossed a tall plant with a short one, 116 00:08:58,233 --> 00:09:00,283 and a green pea with a yellow one. 117 00:09:03,455 --> 00:09:06,675 Mendel found that you would get a yellow pea every time. 118 00:09:10,158 --> 00:09:12,248 We didn't have a word for the power of the yellow over 119 00:09:12,421 --> 00:09:14,161 the green until Mendel coined it. 120 00:09:14,989 --> 00:09:17,599 He called that quality "dominant." 121 00:09:17,992 --> 00:09:20,822 And to his delight, he found that he could predict what would 122 00:09:20,995 --> 00:09:23,685 happen in the next generation of peas after that. 123 00:09:26,348 --> 00:09:29,128 One in four pea plants would be green. 124 00:09:30,526 --> 00:09:34,746 Mendel named the hidden trait that popped up in the next crop, "recessive." 125 00:09:35,792 --> 00:09:38,102 There was something he called "factors," 126 00:09:38,447 --> 00:09:42,277 hidden inside the plants that caused particular characteristics. 127 00:09:42,930 --> 00:09:45,850 And they operated by a law that Mendel could describe 128 00:09:46,020 --> 00:09:48,590 with a simple equation, like gravity. 129 00:09:51,286 --> 00:09:53,806 Charles Darwin and Gregor Mendel didn't know it, 130 00:09:53,984 --> 00:09:56,384 but the two scientists were deciphering the mysterious 131 00:09:56,552 --> 00:09:59,692 workings of life at the very same moment. 132 00:10:02,210 --> 00:10:05,520 [barking] 133 00:10:05,692 --> 00:10:08,562 Darwin presented the evidence for a oneness with all life. 134 00:10:09,434 --> 00:10:12,094 That despite our pretensions to a mystical higher birth, 135 00:10:13,047 --> 00:10:16,527 we were actually relatives to the other beasts and vegetables. 136 00:10:17,181 --> 00:10:20,621 As much a part of the natural world as any other living thing. 137 00:10:24,058 --> 00:10:26,628 Mendel discovered that there were laws governing the 138 00:10:26,800 --> 00:10:29,500 way life's messages were passed on. 139 00:10:29,846 --> 00:10:33,016 The substitute teacher had invented a whole new field of science. 140 00:10:34,938 --> 00:10:37,898 But nobody noticed for 35 years. 141 00:10:39,900 --> 00:10:42,640 He died never knowing that the world would come to see him 142 00:10:42,816 --> 00:10:45,166 as a giant in the history of science. 143 00:10:46,907 --> 00:10:48,867 Mendel's work was resurrected at the beginning of 144 00:10:49,039 --> 00:10:52,779 the 20th century and he had no more vigorous defender 145 00:10:52,956 --> 00:10:55,736 than the British zoologist William Bateson. 146 00:10:56,612 --> 00:10:59,662 It was Bateson who named the new field of science devoted 147 00:10:59,833 --> 00:11:02,143 to studying these factors. 148 00:11:02,313 --> 00:11:04,143 Genetics. 149 00:11:05,099 --> 00:11:06,839 Bateson and his colleagues worked on developing 150 00:11:07,014 --> 00:11:09,844 new breeds of plants and animals. 151 00:11:10,713 --> 00:11:14,463 He believed that science and freedom were indivisible 152 00:11:14,717 --> 00:11:17,237 and that's how he ran his laboratory. 153 00:11:18,416 --> 00:11:19,896 [inaudible chatter]. 154 00:11:20,070 --> 00:11:21,810 TYSON: Nikolai Ivanovich Vavilov, 155 00:11:21,985 --> 00:11:23,635 a visiting botanist from Russia, 156 00:11:23,813 --> 00:11:26,123 took Bateson's credo deeply to heart. 157 00:11:26,294 --> 00:11:28,784 He wanted to use the new field of genetics to learn 158 00:11:28,949 --> 00:11:31,389 how to feed the world. 159 00:11:32,343 --> 00:11:35,913 He was on his honeymoon but science was his passion. 160 00:11:36,173 --> 00:11:39,183 Even as a child, Vavilov had a sense of urgency. 161 00:11:40,177 --> 00:11:43,917 "Too little time, too much to do," was his lifelong refrain. 162 00:11:45,095 --> 00:11:47,485 [panting]. 163 00:11:51,145 --> 00:11:52,615 [grunts]. 164 00:11:55,671 --> 00:11:57,981 TYSON: How could he have known what was coming? 165 00:12:06,682 --> 00:12:09,822 TYSON: The idea that our planet is a single organism, 166 00:12:09,990 --> 00:12:13,600 a unity, has a ring of hollow sentimentality for many people. 167 00:12:14,995 --> 00:12:17,475 But it's just a scientific fact. 168 00:12:19,521 --> 00:12:22,871 Something is about to happen here, in remote Southern Peru, 169 00:12:24,004 --> 00:12:28,624 in the year 1600 on February 19 at 5:00 PM. 170 00:12:30,532 --> 00:12:33,752 Unsuspecting multitudes and distant foreign capitals 171 00:12:33,927 --> 00:12:37,187 will never know how this event reached around the world 172 00:12:37,365 --> 00:12:39,495 to torment and kill them. 173 00:12:40,194 --> 00:12:41,634 [explosion] 174 00:12:50,900 --> 00:12:54,470 This nasty mixture of sulfuric acid and volcanic ash 175 00:12:54,643 --> 00:12:57,603 will block the sun's rays from

day 178 00:13:06,916 --> 00:13:10,266 the largest explosion in South America in recorded history. 179 00:13:14,576 --> 00:13:16,486 Winter is coming. 180 00:13:17,622 --> 00:13:19,842 Volcanic winter. 181 00:13:25,021 --> 00:13:26,461 For the people of Russia, 182 00:13:26,631 --> 00:13:29,591 it brought the worst winter in six centuries. 183 00:13:29,852 --> 00:13:32,332 For two years, even the summer temperatures would fall 184 00:13:32,507 --> 00:13:34,417 below freezing at night. 185 00:13:34,726 --> 00:13:37,596 Two million people, a third of Russia's population, 186 00:13:37,773 --> 00:13:39,953 would die from the resulting famine. 187 00:13:40,210 --> 00:13:43,300 It led to the downfall of the Tsar Boris Godunov and 188 00:13:43,474 --> 00:13:47,654 all because of a volcano that erupted 8,000 miles away in Peru. 189 00:13:49,132 --> 00:13:52,272 This was not the last famine in Russian history. 190 00:13:52,527 --> 00:13:54,657 Drought and famines occur frequently. 191 00:13:54,834 --> 00:13:57,454 But it wasn't until nearly three centuries later, 192 00:13:57,619 --> 00:14:01,709 in 1891, that the magnitude of suffering was again as ghastly. 193 00:14:03,668 --> 00:14:06,798 Winter came early that year and the crops failed. 194 00:14:07,890 --> 00:14:11,070 Tsar Alexander III was slow to respond. 195 00:14:11,459 --> 00:14:14,589 Wealthy Russian merchants continued to export grain at 196 00:14:14,766 --> 00:14:17,676 a profit even as millions went hungry. 197 00:14:18,466 --> 00:14:21,986 All the Tsar had to offer his starving subjects was "famine bread." 198 00:14:23,297 --> 00:14:27,817 A miserable mixture of moss, weeds, bark and husks. 199 00:14:30,304 --> 00:14:32,704 Half a million Russians perished, 200 00:14:32,872 --> 00:14:35,002 while the aristocracy and the wealthy feasted on fresh 201 00:14:35,178 --> 00:14:38,748 strawberries from the south of France and clotted cream from England. 202 00:14:39,879 --> 00:14:43,839 The Russian Revolution would not explode for another 30 years, 203 00:14:44,013 --> 00:14:47,103 but many historians believe that this famine 204 00:14:47,277 --> 00:14:50,847 was the spark that ignited the long fuse. 205 00:14:51,673 --> 00:14:54,333 It was to make a lasting impression on the hero of 206 00:14:54,502 --> 00:14:58,032 our story, Nikolai Vavilov. 207 00:15:01,335 --> 00:15:03,505 This

grain exporter on Earth, 219 00:15:50,471 --> 00:15:53,301 despite the fact that its farming methods were antiquated. 220 00:15:53,778 --> 00:15:56,478 The Petrovsky Institute was the only place in Russia where 221 00:15:56,651 --> 00:15:59,351 scientists could hope to modernize food production 222 00:15:59,523 --> 00:16:01,223 through the new science of genetics. 223 00:16:02,439 -->

They want bread. 233 00:16:28,988 --> 00:16:32,298 VAVILOV: The farmer has wisdom and is worthy of our respect. 234 00:16:32,469 --> 00:16:35,859 But tragically, he lacks the predictive powers of science. 235 00:16:36,386 --> 00:16:38,386 They cannot foretell which traits will dominate 236 00:16:38,562 --> 00:16:40,302 or which will be recessive. 237 00:16:40,912 --> 00:16:43,922 The farmer plays roulette and he's about as successful 238 00:16:44,090 --> 00:16:45,700 as the average gambler. 239 00:16:51,445 --> 00:16:54,485 Gregor Mendel made it possible for him to know the odds. 240

agriculture became a science and our only hope 243 00:17:04,893 --> 00:17:07,203 to efficiently feed ourselves. 244 00:17:07,548 --> 00:17:09,508 And feed the world. 245 00:17:13,641 --> 00:17:16,171

Vavilov dared to propose a new law of nature. 261 00:18:13,570 --> 00:18:16,400 VAVILOV: Comrades, the same genes perform the 262 00:18:16,573 --> 00:18:19,663 same functions in different species of plants. 263 00:18:20,360 --> 00:18:23,450 This is because they share a common ancestor. 264 00:18:24,190 --> 00:18:27,410 In order to understand evolution and to guide our 265 00:18:27,584 -->

00:19:04,230 --> 00:19:08,150 Vavilov wanted to preserve every phrase of life's ancient scripture, 279 00:19:08,886 --> 00:19:11,496 to ensure its safe passage to the future. 280 00:19:12,281 --> 00:19:15,941 He was among the first to grasp the critical importance of biodiversity. 281 00:19:17,243 --> 00:19:20,293 Vavilov came up with an entirely new concept. 282 00:19:20,463 --> 00:19:23,553 A world seed bank that he hoped would be impervious 283 00:19:23,727 --> 00:19:26,027 to war and natural catastrophe. 284 00:19:26,861 --> 00:19:30,211 And there was a scientific underpinning to this humanitarian goal. 285 00:19:31,474 --> 00:19:35,004 If you could find the earliest living specimens of the plants we eat, 286 00:19:35,435 --> 00:19:39,345 you could parse its sentences and decipher

first European 294 00:20:08,207 --> 00:20:11,337 in modern times to venture into the mountainous regions of Afghanistan. 295 00:20:12,950 --> 00:20:16,130 Riddled with tribal clashes and other dangers, 296 00:20:16,302 --> 00:20:19,522 Vavilov was suspicious of the prevalent hypothesis that 297 00:20:19,696 --> 00:20:22,476 humans invented agriculture in the river deltas. 298 00:20:23,526

Mendel, Nikolai Vavilov, all liars. 371 00:25:26,742 --> 00:25:30,312 Comrade, why do you think the giraffe has a long neck? 372 00:25:31,138 --> 00:25:32,308 STALIN: A giraffe? 373 00:25:32,487 --> 00:25:34,707 Why are you wasting my time? 374 00:25:34,881 --> 00:25:37,621 So it can nibble on leaves at the top of the trees? 375 00:25:37,797 --> 00:25:39,407 LYSENKO: Exactly. 376 00:25:39,581 --> 00:25:41,631 But the scientists say no. 377 00:25:41,801 --> 00:25:44,331 They believe in imaginary, invisible entities called 378 00:25:44,499 --> 00:25:48,679 genes that somehow get changed by equally invisible forces 379 00:25:48,851 --> 00:25:50,811 that tell the giraffe to have a long neck 380 00:25:50,984 --> 00:25:53,464 and a chicken to have a short one. 381 00:25:53,639 --> 00:25:56,509 I don't believe in imaginary things. 382 00:25:56,859 --> 00:26:00,339 But Vavilov does and that's why our people starve. 383 00:26:00,820 --> 00:26:03,610 While he's been off collecting souvenirs, 384 00:26:03,910 --> 00:26:08,090 I've been devising a way to give Mother Russia the thing she needs most. 385 00:26:08,262 --> 00:26:10,962 A harvest of wheat in the dead of winter. 386 00:26:12,788 --> 00:26:15,618 STALIN: If this is true, if you really have this power... 387 00:26:15,835 --> 00:26:17,485 LYSENKO: I do, Comrade. I do. 388 00:26:17,663 --> 00:26:20,013 But I must have a free hand. 389 00:26:20,361 --> 00:26:23,491 No more interference from the bourgeois geneticists. 390 00:26:23,973 --> 00:26:26,113 They are agents of our enemies. 391 00:26:26,280 --> 00:26:30,460 They want to starve Russia into submission. 392 00:26:33,548 --> 00:26:36,118 TYSON: That's not why the giraffe's neck is long. 393 00:26:36,290 --> 00:26:38,770 How could Stalin have fallen for that one? 394 00:26:38,945 --> 00:26:40,335 It was easy. 395 00:26:40,511 --> 00:26:43,211 He desperately wanted to believe it. 396 00:26:43,732 --> 00:26:47,692 Lysenko was peddling the long discredited theory of an early 397 00:26:47,867 --> 00:26:51,257 19th century naturalist named Jean-Baptiste Lamarck. 398 00:26:52,349 --> 00:26:54,739 He believed that acquired characteristics, 399 00:26:54,917 --> 00:26:57,307 let's say the length of a giraffe's neck from straining 400 00:26:57,485 --> 00:26:59,175 to get at those leaves up high, 401 00:26:59,356 --> 00:27:02,656 could be inherited by the next generation. 402 00:27:02,838 --> 00:27:05,838 He failed to grasp that it took millions of years of 403 00:27:06,015 --> 00:27:09,795 evolution and higher survival rates among the generations of 404 00:27:09,976 --> 00:27:13,496 giraffes with even slightly longer necks to result 405 00:27:13,675 --> 00:27:16,365 in a tall modern giraffe. 406 00:27:16,547 --> 00:27:20,157 This increasingly long neck of the giraffe was due to random 407 00:27:20,334 --> 00:27:24,084 mutations in the genes that happened to lead to a more successful giraffe. 408 00:27:25,208 --> 00:27:28,078 Not their neck stretching exertions. 409 00:27:28,255 --> 00:27:31,945 This had been Charles Darwin's revolutionary insight. 410 00:27:32,128 --> 00:27:34,908 Evolution by natural selection. 411 00:27:36,306 --> 00:27:39,176 Lysenko whispered in Stalin's ear that he could fulfill 412 00:27:39,353 --> 00:27:42,883 a centuries old Russian dream and end the famine that 413 00:27:43,052 --> 00:27:45,452 threatened Stalin's grip on the country. 414 00:27:45,620 --> 00:27:49,150 Lysenko would soak the wheat seeds in ice water 415 00:27:49,319 --> 00:27:52,629 so that they could still thrive in the ice and snow. 416 00:27:52,801 --> 00:27:55,941 A process he called vernalization. 417 00:27:56,413 --> 00:27:59,333 Lysenko falsely claimed that the plants offspring 418 00:27:59,503 --> 00:28:02,073 would inherit the resistance to cold. 419 00:28:02,245 --> 00:28:06,285 No time-consuming painstaking crossbreeding required. 420 00:28:06,467 --> 00:28:09,037 Only one thing stood in his way. 421 00:28:09,513 --> 00:28:13,563 Vavilov and his stubborn adherence to genetics. 422 00:28:14,954 --> 00:28:17,614 The bitter irony was that while Lysenko was spinning 423 00:28:17,783 --> 00:28:19,963 fantasies of abundance for Stalin, 424 00:28:20,655 --> 00:28:23,435 Vavilov and his team were crossing wheat species from 425 00:28:23,614 --> 00:28:26,314 higher altitudes that actually would've resulted 426 00:28:26,487 --> 00:28:29,927 in heightened food production in Russia. 427 00:28:30,534 --> 00:28:32,844 As Vavilov rushed to the Kremlin, 428 00:28:33,015 --> 00:28:36,235 all he could think about was the work that needed to be done. 429 00:28:36,671 --> 00:28:39,411 He was on a collision course that would doom him 430 00:28:39,587 --> 00:28:41,497 and countless others to starvation. 431 00:28:42,503 --> 00:28:46,333 [grunts]. 432 00:28:51,033 --> 00:28:53,693 TYSON: Vavilov knew that no man could

00:29:16,929 --> 00:29:19,189 Their wives are frantic. 439 00:29:19,366 --> 00:29:21,496 Lysenko takes every opportunity to blame you 440 00:29:21,672 --> 00:29:23,332 for the famine. 441 00:29:23,500 --> 00:29:26,420 I tell you, we must stop the experiments in genetics. 442 00:29:28,984 --> 00:29:31,334 VAVILOV: Carry on quietly with your work. 443 00:29:31,508 --> 00:29:33,118 No matter what happens. 444 00:29:33,293 --> 00:29:34,603 We must hurry. 445 00:29:34,773 --> 00:29:37,083 We must be like Michael Faraday, 446 00:29:37,253 --> 00:29:39,913 working hard and keeping accurate notes

00:30:04,628 --> 00:30:08,328 in the Ukraine led to one of the darkest chapters in human history. 455 00:30:09,982 --> 00:30:13,512 It was a famine so severe and widespread that instead of 456 00:30:13,681 --> 00:30:16,121 being known by a year and a place, 457 00:30:16,292 --> 00:30:18,732 it was given a name all its own. 458 00:30:19,426 --> 00:30:23,596 Holodomor, meaning the extermination by hunger. 459 00:30:26,433 --> 00:30:29,573 Stalin's zeal to push the kulak peasants off their farms 460 00:30:29,740 --> 00:30:32,920 and into factories had become a policy of genocide. 461 00:30:34,267 --> 00:30:37,787 LYSENKO: Vavilov and his geneticists continue to speak against you. 462 00:30:38,445 --> 00:30:40,135 I cannot bear it. 463 00:30:40,316 --> 00:30:43,276 TYSON: Stalin knew that getting rid of Vavilov might be trouble. 464 00:30:43,754 --> 00:30:46,504 The global scientific community admired Vavilov for 465 00:30:46,670 --> 00:30:48,930 his ideas and

alive. 560 00:36:35,018 --> 00:36:38,808 LILIYA: Until we do, we must find it within ourselves to 561 00:36:38,979 --> 00:36:41,809 do as Nikolai Ivanovich would. 562 00:36:42,591 --> 00:36:46,641 If the siege lasts, our fellow citizens will get very hungry. 563 00:36:47,944 --> 00:36:51,864 This building contains several tons of edible material. 564 00:36:53,167 --> 00:36:56,867 We must figure out how to protect every last seed 565 00:36:57,824 --> 00:37:01,184 for the time when the world returns to its senses. 566 00:37:02,394 --> 00:37:07,234 TYSON: In all of history, no team of scientists has ever been tested so cruelly. 567 00:37:08,487 --> 00:37:13,487 They were pushed beyond the breaking point and yet they did not break. 568 00:37:19,498 --> 00:37:22,278 TYSON: On Christmas Day alone in 1941, 569 00:37:22,457 --> 00:37:25,587 4,000 people starved to death in Leningrad. 570 00:37:26,592 --> 00:37:30,162 The city had been under siege by Hitler's army for more than 100 days. 571 00:37:31,423 --> 00:37:36,043 The temperature was -40 degrees and the city's entire infrastructure had collapsed. 572 00:37:37,994 --> 00:37:41,004 It was only a matter of time, Hitler thought to himself, 573 00:37:41,171 --> 00:37:44,311 before Leningrad succumbed to his will. 574 00:37:44,479 --> 00:37:48,829 No city could endure such suffering for very long. 575 00:37:50,616 --> 00:37:52,396 TYSON: While Stalin fretted over the safety of the 576 00:37:52,574 --> 00:37:54,714 artworks at the Hermitage Museum, 577 00:37:54,881 --> 00:37:57,581 he never gave a single thought to Vavilov's seed bank. 578 00:37:58,972 --> 00:38:02,672 But Hitler had already taken the Louvre art museum of Paris. 579 00:38:02,845 --> 00:38:05,365 He coveted something much more precious. 580 00:38:05,544 --> 00:38:07,374 Vavilov's treasure. 581 00:38:08,155 --> 00:38:11,195 Hitler had established a special tactical unit of the SS, 582 00:38:11,376 --> 00:38:15,726 Russland-Sammelcommando, the Russian collector commandos, 583 00:38:15,902 --> 00:38:17,952 to take control of the seed bank and retrieve 584 00:38:18,121 --> 00:38:20,991 its living riches for future use by the Third Reich. 585 00:38:21,647 --> 00:38:24,077 They waited at the ready, like a pack of Dobermans, 586 00:38:24,258 --> 00:38:26,608 straining to be unleashed on the institute. 587 00:38:27,348 --> 00:38:30,128 The botanists were now down to a ration of two slices 588 00:38:30,308 --> 00:38:32,088 of bread per day. 589 00:38:32,266 --> 00:38:34,566 But still, they continued their work. 590 00:38:34,921 --> 00:38:39,271 In a way, the German army was the least of their worries. 591 00:38:39,447 --> 00:38:42,447 [yelling]. 592 00:38:46,019 --> 00:38:48,059 KRIYER: If only Vavilov were here. 593 00:38:48,238 --> 00:38:50,328 I feel so lost without him. 594 00:38:50,502 --> 00:38:54,202 STCHUKIN: Dear comrade, as painful as it is, 595 00:38:54,375 --> 00:38:57,675 we must accept that he's gone forever. 596 00:38:58,074 --> 00:39:00,994 TYSON: But Vavilov was alive... barely. 597 00:39:02,383 --> 00:39:06,563 He had been moved to another prison in another city. 598 00:39:06,822 --> 00:39:10,572 VAVILOV: I am 54 years old, with a vast experience and 599 00:39:10,739 --> 00:39:13,919 knowledge in the field of plant breeding. 600 00:39:14,743 --> 00:39:17,493 I would be happy to devote myself entirely to 601 00:39:17,659 --> 00:39:19,879 the service of my country. 602 00:39:20,053 --> 00:39:24,803 I request and beg you to allow me to work in my special field, 603 00:39:24,971 --> 00:39:27,631 even at the lowest level. 604 00:39:27,800 --> 00:39:29,800 TYSON: But no answer ever came. 605 00:39:29,976 --> 00:39:32,406 The state had decided not to shoot him. 606 00:39:32,587 --> 00:39:34,887 They had a crueler fate in mind for the man who did 607 00:39:35,068 --> 00:39:38,938 more than any other to eliminate famine and hunger, 608 00:39:39,115 --> 00:39:42,465 he would be deliberately and slowly starved to death. 609 00:39:47,472 --> 00:39:52,872 TYSON: 800,000 other human beings had starved to death in Leningrad. 610 00:39:53,129 --> 00:39:57,129 Besieged by the German forced from September of 1941 until 611 00:39:57,307 --> 00:40:01,567 January of 1944, the city somehow still managed 612 00:40:02,269 --> 00:40:05,529 to hold out against the relentless assault. 613 00:40:06,012 --> 00:40:09,232 The meager rations of two slices of bread a day had 614 00:40:09,407 --> 00:40:12,627 run out long before, and the protectors of Vavilov's 615 00:40:12,801 --> 00:40:16,811 treasure began to succumb to hunger amidst the plenty that 616 00:40:16,979 --> 00:40:20,329 their sacred honor prevented them from consuming. 617 00:40:23,203 --> 00:40:26,733 Botanist Alexander Stchukin, specialist in groundnuts. 618 00:40:45,051 --> 00:40:49,751 Liliya Rodina, expert on oats. 619 00:40:56,062 --> 00:41:01,242 Dimitry Ivanov, world authority on rice. 620 00:41:06,072 --> 00:41:09,552 The botanists perished from hunger, 621 00:41:09,728 --> 00:41:13,778 and yet not a grain of rice in the collection was unaccounted for. 622 00:41:33,403 --> 00:41:36,583 And what of Vavilov's nemesis, Trofim Lysenko? 623 00:41:37,146 --> 00:41:39,446 He maintained his death grip on Soviet agriculture 624 00:41:39,627 --> 00:41:42,667 and biology for another two decades, 625 00:41:42,848 --> 00:41:45,458 until three of Russia's most distinguished scientists 626 00:41:45,633 --> 00:41:49,683 publicly denounced him for his pseudoscience and his other crimes. 627 00:41:51,987 --> 00:41:55,337 And what of Vavilov's brother, Sergey, the physicist? 628 00:41:56,339 --> 00:42:00,169 Stalin made him chairman of the Soviet Academy of Sciences. 629 00:42:02,476 --> 00:42:05,696 After Stalin's death and the recognition of the damage 630 00:42:05,871 --> 00:42:08,661 he and Lysenko had done to the Soviet Union, 631 00:42:08,830 --> 00:42:13,050 Nikolai Vavilov could once again be talked about in public. 632 00:42:13,313 --> 00:42:16,883 The Institute of Plant Industry was renamed after him, 633 00:42:17,056 --> 00:42:20,096 and it still thrives. 634 00:42:20,363 --> 00:42:23,583 And this is here because of his life and work. 635 00:42:23,758 --> 00:42:26,458 This Svalbard Global Seed Vault is buried deep beneath 636 00:42:26,631 --> 00:42:28,851 the Earth at the top of the world. 637 00:42:29,024 --> 00:42:34,254 It can hold four and a half million kinds of seeds underground. 638 00:42:34,639 --> 00:42:39,379 So why didn't the botanists at the Institute eat a single grain of rice? 639 00:42:39,774 --> 00:42:42,864 Why didn't they distribute the seeds and nuts and potatoes 640 00:42:43,038 --> 00:42:46,088 to the people of Leningrad who were dying of starvation 641 00:42:46,259 --> 00:42:48,169 every day for more than two years? 642 00:42:50,263 --> 00:42:53,013 Did you eat today? 643 00:42:53,179 --> 00:42:56,439 If the answer is yes, then you probably ate something that 644 00:42:56,617 --> 00:43:00,057 descended from the seeds that the botanists died to protect. 645 00:43:01,491 --> 00:43:05,231 They gave their lives for us. 646 00:43:08,107 --> 00:43:14,417 If only our future was as real and precious to us as it was to them. 647 00:43:55,110 --> 00:43:57,460 Captioned by Cotter Captioning
