02:29More than 10,000 years ago
02:30This grass has become a friend of humankind.
02:33But it is little known today.
02:38Its offspring have a brand new appearance
02:41Traveled all over the world
03:07Standing at both ends of more than ten thousand years of time
03:10They looked at each other.
03:12Different shapes
03:14Yet they share so many common genes.
03:20If they were like people
03:22Would you think about this kind of question?
03:26Where do we come from?
03:28Where are we going?
04:00Chinese subtitle volunteer Li Zongsheng
04:12Each offspring receives the best care from its own species.
04:18Because they carry the future of the population.
04:22Human babies preparing to wean from breast milk
04:25Before we begin to savor the diverse culinary delights of humankind
04:27The digestive system needs to gradually adapt to dietary changes.
04:42Baby rice cereal made from rice
04:45It is a widely recognized infant erosion
04:49Rice is rich in nutrients
04:51Mild ingredients
04:54Globally
04:55Opening the door to diet for human infants
05:01Rice is the name used by humans.
05:04For rice
05:06They are rice seeds
05:07Make your own child
05:08Making the hope of inheritance
05:17The warm water was absorbed by the seeds.
05:19The life force within the seed is triggered
05:23The tender shoots broke free of the seed coat and peeked out.
05:29The cycle of life begins here.
05:35early life of rice
05:37surviving entirely on the energy in rice seeds
05:40It must be before these energies are exhausted.
05:42Grow enough leaves

06:59A few days later
07:01These tiny lives are only a few centimeters long.
07:04But it already has roots for absorbing water.
07:08With leaves used to convert energy through photosynthesis
07:15They are now independent new lives.
07:25The seed has also completed its mission of passing on its seeds.
07:34More than 10,000 years ago
07:36The ancestors of these rice varieties were considered by people to be a type of grass.
07:41It is known as wild rice today.
07:49In nature
07:51Plants give their all to pass on their genes.
08:00Wild rice seeds turn a subtle dark brown when ripe.
08:06Once mature
08:07The seeds will fall off in the shortest possible time.
08:11Burying themselves in the mud to avoid the covetous gazes of animals.
08:28Besides avoiding
08:29Wild rice seeds can also fight.
08:37The long awns at the tip of the seed
08:41It seemed to threaten to pierce the throat of the thief.
08:53These awns also have rice hooks.
08:55It could potentially hook onto passing animals and carry them to distant places.
09:01This is the instinct of wild rice to reproduce.
09:04It also reflects their ambition to expand proactively.
09:11That's exactly it.
09:12It hooked people more than 10,000 years ago
09:16The prelude to dancing with people has begun.
09:20It has become the familiar cultivation path.
09:29Modern cultivation methods
09:30Because of people's needs
09:32Seeds no longer grow thorns
09:35No longer falls off on its own
09:37Instead, they wait for people to harvest them.
09:40From the perspective of the waterway itself
09:42Its seeds were placed in danger.
09:46Needs to rely on human protection
10:01And it is precisely the cultivation path that depends on people.
10:04Embark on a journey of collaboration with others.
10:09In people's eyes
10:10They are no longer grass
10:11It truly became the Way.
10:13Became one's partner
10:18We can leave our familiar surroundings together.
10:20Let's go on an adventure
10:30Waterway wants to leave its homeland
10:32It's not that easy.
10:34Swamps are a special environment
10:37Excess water resources
10:39It will submerge the plant's roots.
10:40This can lead to root hypoxia or even rot.
10:46Wild trails are precisely the few
10:48Plants that can adapt to swampy environments
10:51In flooded environments
10:53After growing for millions of years
10:55The swamp shaped it
10:57Dependence on water
11:00Waterways' dependence on water
11:02This makes it difficult for it to easily
11:03Following people's migration
11:06To take the waterway with you
11:08People need to bring
11:09The entire home of the waterway
11:29Pig ring
11:30Class I protected animal in China
11:32These birds love to live in wetlands
11:35Attracted by the clean water source in the rice paddies
11:38They also settled down next to the paddy fields.
11:57More than 6,000 years ago
11:59Paddy fields began to appear across the vast land of China.
12:03During the more than one hundred days of growth in the waterway each year
12:07Large areas of land were irrigated with running water.
12:10It has become a home exclusively for the waterways.
12:19With paddy fields
12:20Waterways were able to migrate along with people.
12:24Paddy fields became a testament to human and waterway migrations.
12:28This footprint is almost all over the world.
12:35In Italy
12:36People built the canal
12:37Water from the Po River was diverted into large rice paddies.
12:47In Madagascar, Africa
12:49There are also traces of paddy fields.
12:57Starting from China
12:58Waterways have taken root in 113 countries around the world.
13:06The paddy fields also altered the lava of the land there.
13:35More than 1,300 years ago
13:36During the Tang Dynasty
13:38Some ethnic groups migrated from the north to the south and settled in what is now Yunnan, China.
13:43Inside
13:44They were powerless to compete with the locals for the precious freshwater resources in the low-lying river valley.
13:48source
13:50To survive
13:51They only have one way.
13:54Conquer the mountains
13:58People can walk to the top of the mountain.
14:01But how can waterways cope with the life-threatening challenges of high mountains?
14:08Every plant species that survives here has evolved over the previous year.
14:13They found survival skills in it.
14:44Deep-rooted
14:45Explore
14:45The enormous challenges here
14:48They need to be on the summit of a mountain where there are no rivers.
14:51They need to be on the summit of a mountain where there are no rivers.
15:16Until today
15:19The people here are still grateful to the mountains for sheltering them.
15:25Before planting rice each year
15:27They would all sing their gratitude to the forest.
15:31Because in their simple mindset
15:33There is some mysterious connection between the forest and the water.
15:42In fact, through scientific understanding
15:44People discovered
15:45The secret of water sources lies in the workings of nature.
16:29Water mist, freed from the constraints of gravity, carried water resources to the high mountains.
16:35Plants gave the water mist a reason to settle.
17:08The secret of water mist defying gravity
17:37The secret of water mist defying gravity
17:47The secret of water mist defying gravity
17:49The secret of water mist defying gravity
17:57The secret of water mist defying gravity
18:22The people here build ditches using the most primitive methods.
18:26Gathering and distributing the precious water flowing from the forest
18:30Over a thousand years
18:32They built more than 4,000 ditches here.
18:36With such labor
18:37Only then could they simulate swamps atop high mountains.
18:40Creating an aerial home for rice
18:47Transform the sloping mountain into
18:49A staircase composed of countless small flat surfaces
18:54Water flows on each step
18:56Rice paddies were formed during the casting process.
19:00The rice paddies climbed up these steps.
19:12The field is an ecosystem
19:15In the natural water cycle system
19:17Humans have incorporated rice and its habitat into this.
19:27Without forests and vegetation to conserve water sources
19:30Such an ecosystem cannot function sustainably.
19:34These forests still cover more than 75% of the mountainous area.
19:43Nature gave up some space
19:46They took in people and rice.
19:49Human restraint and gratitude maintain the healthy functioning of the entire ecosystem.
19:54OK
19:56In this homeland
19:57People work
19:59We also pray for nature's embrace and the bounty of the rice.
20:13In agrarian civilization
20:14The relationship between humans and plants
20:16It is not about exploitation and taking.
20:19It is to coexist with heaven and earth
20:21Coexisting with all things
20:32About thirty days after sprouting
20:35The rice has grown from a seedling into a robust young adult.
20:40They started to feel crowded.
20:44However
20:44The space in the central area has already been completely divided up.
20:50I can't imagine what it would be like if more golden leaves grew out.
20:57It seemed as if a fierce competition was about to begin.
21:07Fortunately, after thousands of years of coexistence
21:09People have already grasped the current demand for rice.
21:16People arranged according to the space required for mature rice.
21:19Transplant seedlings at certain intervals.
21:22This is rice transplanting.
21:43Transplanting rice seedlings is hard work for people.
21:46For the life of rice
21:48It was an adventure
21:55Rice seedlings to be prepared
21:56Replenish fluids while soaking in water
22:00This is crucial to them
22:05At this moment, the leaves are unaware that their roots have been separated from the water source.
22:09It is still photosynthesizing.
22:11Producing glucose
22:13It is also continuously losing water.
22:21The countdown to life has begun.
22:25The mountain road is steep
22:27The new home for these rice seedlings is still a long way off.
22:30Run faster
22:40Pour a little water
22:42Hopefully the rice will last longer.
23:13Pour a little water
23:33The reward for perseverance under the scorching sun
23:36It's a spacious new home
23:38Waterways that have been through danger
23:40Back in the water
23:42Enjoy a relaxed new life
24:06Within about a month
24:08Space in rice paddies
24:09Almost filled with rice plants
24:11It's like a kingdom of rice paddies.
24:17but
24:18In the seemingly peaceful rice paddies
24:20Actually, danger lurks everywhere.
24:25Fated Enemy
24:27It appeared in a new guise
24:33Like the wild ancestors of weeds and rice, wild grasses also grew in the same way.
24:39They were once just weeds in people's eyes.
24:46Until the wild path met humans
24:49Become a darling of the people
24:51Meanwhile, withered grass became the enemy in people's eyes.
24:59People are weeding in the rice paddies.
25:03The goal is to eliminate these plants that are defined as enemies.
25:08For the life of rice
25:09Clearing all obstacles for the life of rice
25:17However, the weeds did not give up.
25:22In war
25:24What's more terrifying than a tenacious enemy is...
25:26The Invisible Enemy
25:51camouflage
25:52The withered grass became almost identical to the rice.
25:57This phenomenon is called mimicry in biology.
26:03Weeds that mimic the appearance of rice
26:05blatantly entering the house
26:08Seizing rice's survival resources
26:14Only rice has white leaflets.
26:17The weeds have not yet succeeded in imitating it.
26:22But in the vast rice paddies
26:24The disguise of the withered grass was successful enough.
26:30And all of this is actually thanks to humankind.
26:35People's year-after-year efforts to weed
26:38Attempts to remove weeds from the rice paddies
26:42In order to survive
26:43Weeds must constantly evolve
26:46Some weeds during their growth period
26:49It became similar in appearance to rice.
26:52Luckily, it escaped the cleanup.
26:55Until near maturity
26:57They only then abandoned their pretense
26:59To the world in its true form
27:03But before people pulled them out
27:05The seeds had already been scattered.
27:10The dead survive
27:11In the world of rice paddies
27:14Human selection has replaced natural selection.
27:17Instead, it filtered out even stronger opponents.
27:30Humans and rice not only have a common enemy
27:33They also share common expectations.
27:36A rice plant sprouts in spring
27:38Before winter arrives
27:40Then the cycle of life will be completed.
27:43Entering the height of summer
27:44It has no time to enjoy the laziness of summer.
27:47The pressure of the voyage is already beginning to show.
28:02Around seventy days after the rice germinates
28:05Golden stalks of rice
28:06A force began to stir.
28:31The one who couldn't wait to break free of the golden rod was the thief.
28:43The fragments on the surface were densely packed with shadow shells.
28:48These shadow shells are less than one centimeter long.
28:51They are about to become the stage for the birth of life.
29:00High temperature and high humidity around noon
29:02This marks the beginning of the transmission of life.
29:14The shadow shell split in the middle
29:17The rice is flowering
29:23These flowers are less than one centimeter long
29:25It is people's hope for the continuation of life with rice.
29:34In the tiny space inside the shadow shell
29:36Six anthers were produced
29:43The anthers were brimming with pollen.
29:46They are carriers of rice sperm.
29:49The egg cell must be found as soon as possible.
29:57At this point, at the bottom of the shadow shell
29:59Even the stigma, no bigger than a sesame seed, protruded.
30:05The stigma opened as wide as possible
30:07Looking forward to the arrival of pollen
30:17The anthers split open
30:19Pollen must act quickly.
30:27The stigma is tiny
30:29Pollen can easily miss it.
30:32And within an hour
30:34The anthers will fall below the stigma.
30:38Once you miss it, the chance is slim.
30:51Of course, rice did not represent all hope.
30:53It all comes down to luck.
30:55It did its best
30:56Each shadow shell provides
30:58Approximately 12,000 pollen grains
31:00Used to increase the chances of success
31:24Fortunately, each stigma only needs one pollen grain.
31:32Successful fertilization
31:34This rice flower can now safely take root.
31:47For millions of years
31:48Rice has thus multiplied.
31:50Using its own pollen to fertilize itself
31:56In environments where no insects help with pollination
31:59This ensured the survival of the population.
32:04Plants that reproduce in this way
32:06Known as a self-pollinating plant
32:13However, even with such a mechanism
32:16When faced with the myriad changes of nature
32:19Rice also has its moments of despair.
32:28The anthers of this rice flower have just begun to peek out.
32:32These six flower buds floated in the air.
32:35There is no sign of falling.
32:41Like a cruel joke from nature.
32:46Its anthers contain no pollen.
32:52As a self-pollinating plant
32:54Not a single pollen
32:57Therefore, the possibility of life reproduction would cease.
33:04out of instinct
33:05It still bloomed.
33:08out of instinct
33:10It still began to wait.
33:15Actually, it's not just that it's waiting.
33:18There is a whole area here.
33:20Rice without pollen
33:22They are all waiting.
33:24Persist
33:51Persist
34:17The wind is coming
34:19There is also a large amount of active pollen in the wind.
34:22Where did this pollen come from?
34:30Inlaid planting in large areas
34:31The middle of the sterile rice without pollen
34:34They are rows and rows of normal rice paddies.
34:37The sharpness produced by drones
34:40The pollen of normal rice was blown away.
34:43Donated to sterile rice
34:49Why is that?
34:50Large areas of sterile rice and normal rice need to be planted.
34:53Gathered here
34:58The current activity in this large rice paddy

35:03species
35:07rice hybrid
35:08Able to combine the superior genes of different rice varieties
35:12However in the natural environment
35:14There's only a one in ten thousand chance that this will happen.
35:20Compared to fate
35:21People place more faith in creativity.
35:251960s
35:27Chinese rice experts represented by Yuan Longping
35:30Nationwide search
35:35Finally in Hainan
35:37A naturally sterile wild lily was found.
35:43now
35:43Sterile rice provides eggs
35:46Fertility rice provides sperm
35:48That led to the success of hybrid rice.
35:53Hybrid rice technology that originated in China
35:55It is now present in more than 40 countries around the world.
35:59Take root and settle down
36:00For the ever-increasing population on Earth
36:03Safeguarding the bottom line of food security
36:06In the quiet life of rice
36:08Hidden within is the path to self-redemption for people
36:12Between the blooming and withering of flowers
36:14They nurtured each other's innermost thoughts.
36:27Rice after pollination
36:29It will begin the final stage of its life.
36:34In this season
36:35Rice begins to face the challenges of life.
36:38More and more separations
36:43The leaves are the first to begin to recede.
36:47started from the bottom
36:49The blades gradually stopped working.
36:51It started to turn yellow

36:58Save energy for plants
37:02Only the top few leaves
37:05Still standing
37:08These leaves produce glucose through photosynthesis.
37:11Being continuously transported to
37:13Pollination and crushing
37:16These glucose molecules are in the capsule.
37:18It was compressed into starch and stored.
37:21Store energy for seed dormancy and germination.
37:32Within approximately forty-five days
37:34Pour out hundreds of drinking shells
37:36Gradually filled with starch
37:39It's like a mother giving a gift to her child who is going on a long journey.
37:42Pack your bags
37:46The whole plant
37:47From crushed to leaf
37:49Then to the gold pole
37:50They all turned yellow
37:53It uses all the energy
37:55They were all given to the seeds.
38:01Winter is coming
38:02It may not be able to withstand the ravages of wind and snow.
38:06I only hope that next spring when the flowers bloom...
38:09Seeds can give themselves life
38:11A new beginning
38:23The fate of a Dao seed is not in his own hands.

38:59Wind collect
39:01It is the reward for people's hard work throughout the year.
39:04For rice
39:05But it is the leaky wood of life.
39:19Rice fields after harvest
39:21No one paid any attention anymore.
39:23Rice tea was left behind
39:24Withering alone
39:27The birth of order
39:29Neatly blooming
39:31A neat welcome to death
39:33The life of rice
39:34Manipulated and controlled by humans
39:40However, life cannot be completely controlled.
39:45New life sprouted from the withered rice and tea leaves.
39:51People's harvest
39:52What they harvested were their seeds.
39:54It's not their desire to survive.
40:13These tender regenerated rice seedlings
40:15In the upcoming winter
40:17There is not much chance of survival.
40:21But living towards death
40:22This is the fragile life of rice.
40:25Hidden strength
40:28Perhaps there will be a winter that isn't too cold.
40:31It has the opportunity to continue the next cycle of life.
40:35Even the smallest hope
40:36It's worth a try.
40:51After the rice seeds are harvested...
40:53The vast majority did not behave like their ancestors.
40:56Waiting to germinate in the soil
41:00Instead, remove the outer shell.
41:02It turned into rice
41:03A new journey has begun
41:08Rice contains abundant carbohydrates and protein.
41:16These nutrients, after being digested in water
41:18It entered people's diet
41:21It has become an important source of energy for people
41:26Besides directly replenishing the energy needed by the human body, rice
41:29Sculpted by time
41:32It can also stimulate human taste buds in different ways.
41:40In the mountainous area of Moon Mountain in Guizhou
41:42The Dong people still perform an ancient operation to this day.
41:47They put rice and fish together
41:51Fish meat is cured with lactic acid produced from rice fermentation.
42:03Three months
42:06The fish meat was given a new flavor by the rice.
42:19The secret to extending the edible time of fish through rice fermentation
42:24It also accompanied the spread of rice.
42:26It has become a common culture in many rice-cultivating civilizations.
42:31Before rice was introduced to Japan
42:34The people on the Japanese hunting islands mainly get their food from fishing and hunting.
42:38Even today, the Japanese still maintain an ancient way of eating fish.
42:43Mode
42:47Like the immortals of the Dong ethnic group in Guizhou
42:50The Japanese also inherited the method of pickling fish with rice.
42:53To extend the shelf life of fish.
42:56Enjoy the unique sour taste that rice imparts to fish.
43:04This type of fish is called cooked sushi in Japan.
43:15As time goes by
43:17Rice has gradually found its place in the Japanese diet.
43:24Modern sushi evolved from cooked sushi.
43:28Dip your hands in vinegar and then squeeze the rice.
43:31Infuse the rice ball with the sour taste of vinegar.
43:36Among them
43:36The use of vinegar is a long-standing practice in the consumption of cooked sushi.
43:40It brings unique taste preferences to the Japanese
43:48Modern sushi
43:49Fresh rice supports fish and shrimp
43:51The two colors are equally beautiful and complement each other.
43:56Rice-growing civilization and maritime civilization
43:59Perfectly blended on small sushi
44:08Rice in different forms
44:10Provide life-sustaining energy for people in different regions
44:14at the same time
44:15Rice leads the way in rice cultivation
44:17Rooted in different regions of the world
44:20Rice adapted to high mountains
44:22Special environments such as deep water and saline-alkali land
44:29It is said
44:29Worldwide
44:31Cultivated rice varieties developed by humans
44:33More than 140,000 species
44:47However
44:48Is this truly the life that rice plants yearn for?
45:00The rice paddies that should have been uniform
45:03But it became mottled and uneven.
45:10These plants are similar to cultivated rice
45:13Taller and thicker than rice
45:17Is it a new variety cultivated by people?
45:21But why do people's expressions look so solemn?
45:26This phenomenon occurs in rice paddies worldwide.
45:29Widespread
45:32Some characteristics of these rice varieties
45:33Prepared for human needs
45:36Scientists have begun to intervene.
45:41Scientists discovered
45:42They are variants of cultivated rice.
45:48They give these rice varieties
45:50Named Weed Rice
45:56Seeds of weedy rice
45:57Very similar to ordinary rice seeds
46:01However, he already possesses a considerable rebellious streak.
46:07Some weedy rice seeds even have awns growing at the tip.
46:12Like wild rice
46:14It wanted to protect its seeds from being stolen.
46:19A gust of wind
46:20The seeds of weedy rice will fall off.
46:22He fell into the rice paddy and hid.
46:26Avoid potential dangers
46:28Waiting for the best germination time next year
46:36Every characteristic of weedy rice seeds
46:38This is precisely why humans cannot accept weed rice.
46:46The changes in weedy rice are actually a manifestation of plant evolution.
46:51This is an effort that has been made since the rice was still in its wild rice stage.
46:58The direction of plant evolution is not fixed.
47:02Just like the growth state of wild rice
47:04It looks messy
47:06Unpredictable
47:09However, the purpose of evolution in different directions is clear.
47:13It is to cope with all kinds of possible disasters
47:20The attempt to grow weedy rice is seen by humans as a rebellious act of defiance.
47:25However, for the reproduction and survival of the entire rice population...
47:30They are pioneers who dare to explore new paths.
47:34It is the courage to sacrifice oneself for eternity.

48:14People built a wall around the wildlife trail.
48:20The secrets of life hidden in the wilderness
48:23We are not yet able to fully crack it.
48:28Protect it
48:29It's about giving wild animals the freedom to expand the boundaries of life.
48:37It also preserves living species for future human exploration.
48:44The Story of Humans and Rice
48:46Start with grass
48:47Returning to the life of grass to explore the future
48:54A grain of rice enters the soil
48:57Several ears of rice can grow within a few months.
49:00Hundreds or thousands of grains of rice
49:03Each of its cycles
49:05They have all given humanity a thousandfold return.
