As one industrialized strain of corn is dominating the market, it's rapidly replacing thousands of indigenous and local varieties. But what does this transformation mean for our food security and the preservation of agricultural diversity?
In Mexico, Human Footprint host Shane Campbell-Staton explores around a maize vault, a treasure trove of genetic diversity. He joins geneticist Sarah Hearne to unravel the intricate genetic landscape of corn. In a tortilla factory, Shane meets with local Mexican chefs Santiago Muñoz and Daniela Moreno, who are committed to reviving the sacred heritage of maize and preserving cultural traditions through corn.

A gift from Mexico to the world.
The aspect of the story where only one strain becomes thoroughly dominant just makes me think of bananas, where the dominant Gros Michel strain had to be replaced due to disease, and now the strain that replaced it, the Cavendish, is again so dominant that a fungal outbreak could completely throw banana production off balance. We need food diversity, and hopefully seed banks like this one can help us science a way to that goal. Thanks Shane and the whole team at PBS Terra for bringing us these stories!
But in the case of bananas the natural species usually have seeds, so nobody eats them. An interesting case though.
Corn is something very different.
Not as big of a problem as you might think. In Southeast Asia there are dozens of varieties still in use (and ofc also wild varities), which is plenty of genetic diversity to create a new variety when need be.
The Cavendish is starting to die off from the same kind of fusarium that killed the Gros Michel. The search is already on to find a new commercial banana that stands up to green harvest, shipping and has a long enough shelf life to be commercial. The breadth of varieties seen in Asian and South American markets is seldom seen here, like the red bananas and burro bananas.
The Cavendish bananas will probably be gone in 10 or 15 years.
Yea though must proceed with caution regarding strain genetic diversity in 🌽. That debacle with STARLING is still fresh! Can’t repeat that!!!
Another gift from Mexico to the world: Corn 🌽🇲🇽
latinas frr
Corn, tomatoes, potatoes, so much good stuff from the Americas
Nothing like a fresh handmade tortilla 😍
finally you guys took a swipe at this BEAST. The timelapse shot showing the corn sprouting its single cotyledon at 8:26 ish was really cool in reminding me that corn is a grass.
only C4 grass cereal crop baybee!!
Sorghum is also a C4 cereal grass. @@brewskimckilgore6796
I love corn
My best memories are watching my late grandfather plow his gardens with his mule. I loved the corn rows most of all. Wonderful childhood. May my precious grandparents R.I.P ❤❤❤
I love this series. Great stuff, every time.
I used to live temporarily in the Corn capital of the USA. Olivia Minnesota. There is a massive 15' corn cob in the town's park and every year there is a corn festival. It was pretty interesting to see.
What an a-maize-ing episode, and I’m not being corny. Thanks for all the kernels of wisdom, I hope everyone lent an ear!
Off subject, I saw NASA satellite pictures of Tons of oxygen coming from the 🌽 corn fields here in Missouri, I Love riding my bike on the back roads and breathing all the fresh air.
They're not hostile to cyclists on the backroads up there in Missouri? Man we have all these trails down in NWA so the minute you get on a street instead of a trail, everyone get angry. People post about it consistently and it's sad.
Are you riding like you’re a car? If so, try getting car insurance on your bike in case someone hits you…
@@mcgritty8842 I personally ride like I'm a bike.
I've already been hit by an automobile, in a crosswalk, on a bike. So I am very, very proactive about not putting myself in bad spots or anywhere that I'm majorly causing problems for traffic.
If I can't maintain a reasonable speed, I stay off the streets.
But I've also sped past automobiles while riding my bike. (On the actual street) So I'm not like most cyclists in my area.
Corn and oxygen??😮😮 Can we talk more about the science in this ??
@@ammcoariauniversal3511 what do you mean? About the respiration of oxygen that plants do?
06:00 a slight correction.
the bomb makers (Alfred Nobel) got the idea for their bombs from nitrate fertilizers’
tendency to explode. (think Beirut 2020 explosion. that was improperly stored nitrates,
ostensibly for fertilizer production)
the other thing that the dust bowl and New Deal support for corn gave rise to, was Big Agro.
so many farms went under that the various chemical companies that supplied fertilizers,
and were doing pretty well, comparatively, bought the farms at *less* than bargain-basement prices,
amalgamated them, and then hired the formerly independent farmers to run them.
that opened the Pandora's box that is Big Agro as we see it around us today.
but that's a story for....
GTA SA Corn.
In the TV show Jericho there is a farmer telling an out of towner all the great things you can make with corn. He throws in the fictional "cornsicle". Texas State Fair, I'm looking at you: Deep Fried Cornsicle. I know you can do it.
Bruh you ever had a sweet corn fritter? I bet you could freeze a ball of ice cream into the sweet corn ball, and itd be like fried ice cream. But that's not the corn they are talking about in this episode.
@@heavymetalbassist5 The cornmeal that makes the fritters is made of the same corn. You're thinking of corn on the cob vegetable is not the corn in the video.
@WalterWhiteFootballSharing you're talking bout what we call hush puppies. Round here you use sweet corn to make fritters, and people pretty well only grow dent here for animal feed and get our meal from jiffy
"I never left" ... so sweet
I loved this! First, because I teach children at the Penn Museum about (among other things) the human development of corn in the Americas over thousands of years, and second because I love seeing a representation of Mexico that shows its culture and its vibrancy, especially given how the nation is used in cynical political games in the US.
Agree on all the points. White racists in the USA hate Mexico, but fuck haters
Nice video. Loved the human and cultural connection piece too. Love the host as well.
I'm reminded of a scene in the X-Men movie Logan where Wolverine helps a farmer break into the corn field of an immense, high fructose corn syrup producer and how they made the endless, uniform cornfields seem ominous and dystopian
Rain makes corn, corn makes whiskey
Whiskey makes my baby feel a little frisky
I know because of time constraints you could only scratch the surface of this massive topic. I hope you'll dig into related topics (GMOs, climate stress and food security, and more) in the future, but as a standalone glimpse into the subject matter you did a great job. Thanks!
Everything you eat is gmo. Look at the how foods looked in the past vs now. Nothing is actually “natural” or “organic,” they’re just words to sell to specific people
All my homies hate monocultures
Thank you, Mexico 🇲🇽 for sharing avocados, chocolate, corn, peppers, tomatoes, vanilla, and more with the world. These flavors have become staples in our kitchens. 🙏🥑🍫🌽🌶️🍅🍦🌮
we are all corn
can you make fabric or baskets out of the fibrous stems of the Maize plant?
Yes, and paper.
I was going say I believe you can actually
I really want the history of how corn was adapted into far off world cuisines, like the video that just went up about tomatoes in Italy.
Look into Painted Mountain Corn, and the decades long work Dave Christensen did developing it.
This series and presenter are both fantastic!!!
Thanks for sharing the video 😁
Super piece here on corn... I love the mexican culture!
Thanks!
Love this ☺️ Thank you 🌽
It even gave us humor in the form of B&B's "The Great Cornholio!!"
I love Corn Vault's second album-- it's definitely their best one. 😁
Thank you.
Growing food is our way of life
corn and potato has fueled the industrial revolution. everyone should thank central and south americans every day.
Please do explain how that happened.
Corn and potatoes helped keep people feom starving during the great depression… never heard that it had anything to do with industrial recolution
Mexico is in North America.
@@carlosmante Depends. I've usually seen it denoted as Central American.
@Misterjtbgaming it's 100% in north America and is the start of central America. It's still north America.
What an interesting story, didn't think that corn is so important
I get that people love corn. I, on the other hand, am allergic to it. I have to be so careful about what I eat because people put corn in absolutely everything. I'm so sensitive that I can't even take medication that has corn in it. Let me tell you, some liquid medications are vile. Not just to keep kids from taking it. Last year I got bronchitis and the doctor, not my regular doctor, but in the same practice, was going to give me a medication you only had to take 5 days. I informed her that I couldn't take it so she ended up, like normal, giving me the liquid amoxicillin, 10 days, 3 times a day and having to keep it in the refrigerator. Not one of the really bad tasting sort, but I finished the medication 2 days before I needed to fly out of town. Oh, and I had to fly with enough liquid medication to take for the 2 weeks I was going to be out of town. Tow different medications, twice a day. And now I take it 3 times a day.
What a waste of a comment…
Many detractors state ethanol isn’t efficient but these people aren’t farmers and forget the millage grain that ethanol produces. This then goes into animal feed. Engineering explained, I’m talking to you.
Yeah but dent is 4 bucks a bushel. The record for an acre is like 620. 2480 bucks off an acre. A single zinnia plant makes my farm way more revenue per square foot. with way less input.
OP is probably a corn farmer and is sick of people bashing the corn industry…. It does suck and they have abused their crops and use it for trash. Farmers who grow corn to use for syrups are trash and should be shut down
@@heavymetalbassist5 If all the corn fields grew zinnias, you wouldn't be able to give them away, lol
Gives a new meaning to the word "cornhole"
Most of the seeds look like Mexico's variety, colonials talking about the market, what a surprise
I love watching and learning things but I don't like corn unless it's a Street Taco tortilla. I refuse to eat any other kind. Still a very interesting short doc. I subscribed, I already subscribe to PBS I guess I've never come across this channel.
Edit: I forgot about popcorn, I will eat popcorn at the movie theater
It’s not just corn (although corn, by its cultural and commercial importance, is at a level all its own). We have lost biodiversity in so many of our grains, fruits, and vegetables. The huge agribusinesses have crowded out nearly all diversity in favor of just a few super strains. Granted, we need a streamlined way to feed the 8.2 billion humans on the planet, but it doesn’t have to be an either/or proposition. I wish smaller farms (the few that remain) could find easier ways to grow out more of these rare seeds and get them to market.
Yo are what you eat, hence all my jokes are so corny. 😊
I tried to pop some corn in the mirowave once... yeah, didn't go well. Found out after zapping it for probably an hour till it was burnt, that it's a whole other corn. but 30,000+ that's a lot of corn.
Shelbyville Grampa: And with that, a mighty cheer went up from the heroes of Shelbyville. They had banished the awful lemon tree forever, because it was haunted. Now let's all celebrate with a cool glass of turnip juice.
It is false to say that corn is not digestible by humans. While nixtamalized corn is more easily digested, cornmeal, corn grits (usually), and frito-style corn chips are made from corn that has not been nixtamalized.

This is, by far one of the most uplifting, enlightening and just plain enjoyable docs I have seen in a long time. Thank you so much.❤
How corny.
Henlo, i wish to purchase a CornCube!
Wheat gang where you at 🥖💪
Going to be real, after seeing what corn is sued to represent, I was very confused by the opening of this video 😂
Grain staples helped build civilization. Too many carbohydrates in the diet gmo or not has contributed heavily to the obesity, diabetes, and all other issues plaguing the modern human's health. Along with seed oils or "vegetable" oils. It's time to let the stuff go as far as for human consumption. Thank you corn, rice and wheat for you work but we can get by without you now.
I wish they spoke in Spanish bc then they would explain themselves better but still a great video 👍🏼
That's corny 🌽😂
aMAIZEing.
So close. Amaizeing is what you were looking for :)
@@kyokoyumi Thanks! Corrected :)
Corn is one of the thirstiest of all crops & is a heavy feeder too. And one plant only produces 2-3 ears of corn. And in the store at the height of the season it is cheap. Seems like it wouldn’t be the wisest choice of crops to grow. It is sad that so many varieties are no longer widely grown.
It's the highest yielding crop that can be grown, & where enough or excess rain falls free from the sky, it doesn't matter how much water it uses.
corn syrup kills americans lol
8:38 That laptop's desktop screen made me twitch.
If you're going to make a show about corn and you're going to try and say, "maíz" 10+ times at least learn how to pronounce it correctly.
Homie, depending on your region will determine how you say it…. Have you ever left your local area?
i feel like this video is a bit cornographic.

Americans have an unhealthy obsession with maize
Americans? Lol, you're welcome.
Mexicans are Americans . I guess you are an cousin of Erdogan.
Did you really have to do that? Was that point relevant to the conversation?
Good for you. Feel good about yourself I guess
The PBS Video makes is seem like Mexicans domesticated Corn
When it was First Nations aka Native Americans that domesticated Corn 4,500 years ago.
Read the book '1491' by Charles Mann
Who do you think Mexicans were before the Spanish?
The earliest physical evidence for domesticated maize, what some cultures call corn, dates to at least 8,700 calendar years ago, and it was probably domesticated by indigenous peoples in the lowland areas of southwestern Mexico, not the highland areas.
@@daharos Please point me to your source for the dates and location of Maize, does not sound right but there is always new info.
Imagine trying to say that one group of people was the first to domesticate a crop… not like several groups could do it at the same time…
Such a pathetic way thinking. “Only one culture could have created something and so no other cultures could have done it“
@@jerrodbroholm4338 Mexicans are a MIX of First Nations and Spanish. So NOT the people that domesticated Corn.
Gmos🤮🤮🤮
How corn destroyed human health
You're being ignorant. That's not corn, that's processed foods. When you turn corn into plastic or high fructose corn syrup yeah it is going to be bad for you.
I'm willing to bet $100 you don't even know how to cook corn correctly.
@@georgewashington7829 Ya exactly. My mom just boils them in water, I never cooked them except put some can corns in my fried rice, or boil them in my soup. Anyway, taste good, just I don’t know how my body digest them. Seems like they pass right through my digestive tract intact.
Eating a high carbohydrate diet is an issue, entirely different from any one food item. Most diet reporting is bogus.
@@tomhalla426 ya, I guess it should be the problem of HFCS, not the corns, since corns just do a short visit in your body and gone completely intact in a day or two.
@@LittleRadicalThinker If you don’t chew sweet corn, yes. Masa does get digested.
What a waste of natural resources.
At 6:51, seriously guys even educational videos are filled with subliminal messages. Getting tired of this. 😮💨
Maybe you're just a bit sensitive.
@@TheDanEdwardsnah they’re just weird
