There’s a reason why bananas are the world’s favorite fruit. "The History and Domestication of Bananas." Discovery of Sweet Bananas . Another complication: Those seeds can’t simply be planted in soil. But the status of these finds as domesticated bananas has been disputed. And what has left them so … Without the genetic modification by selective breeding, bananas would be almost inedible. In 2001, a bunch of bananas took the title of the “largest bunch of bananas.” It held 473 individual bananas or “fingers” and weighed a whopping 287lbs (130 kg). The sterile domesticated banana is the result of ancient crossbreeding between wild species. Meanwhile, oblivious to the global catastrophe their cousins are facing, Chatsworth's plants continue to produce between 30 and 100 bananas a year to be eaten by the Cavendish family and their guests. Having said that, understanding what makes a banana plant happy will help you grow it just for fun and under sub-optimal conditions as well.) But surprisingly, actual potassium levels are pretty low per typical food serving, averaging about 8% of the daily value. They were also grown in Southeast Asia. Another way is to expose clumps of cells to a nutrient bath. You can not grow the usual bananas from seeds. Mary Wickison (author) from Brazil on March 19, 2019: Only dispersal by sea, carried perhaps by migrating people, is likely to have been rapid enough to bring domesticated bananas to Sri Lanka an estimated 800 years after their first certain appearance in Papua New Guinea. Cultivating Bananas . Bananas are planted at a typical density of between 1500-2500 plants per square hectare. Less than 1,000 years separates the first certain appearance of phytoliths of cultivated bananas at Kuk Swamp, the earliest example of domesticated bananas anyone has discovered, and the first appearance of phytoliths of domesticated plants in Sri Lanka. Even today, the leaves, flowers, fruits, stems, and rhizomes of the two wild banana species on Sri Lanka are still used. A typical example is the banana, once a prized exotic novelty, but now a staple in many countries’ supermarkets. All edible bananas today are hybridized from Musa acuminata (diploid) or M. acuminata crossed with M. balbisiana (triploid). They contained many large, hard seeds and minimal pulp and were considered to be a strange and exotic alien fruit. But after the earliest appearance of the phytoliths of domesticated bananas, about 6,000 years ago, we found that phytoliths of wild bananas declined sharply. K. Kris Hirst is an archaeologist with 30 years of field experience. Modern bananas are sterile, containing only tiny residual seeds, so new banana plants are propagated from cuttings. Bananas are a great source of fiber, potassium, vitamin B6, vitamin C, antioxidants and are known to be good for cardiovascular and digestive health. Global connections and exchange may be perceived as part of the modern world—but it is becoming increasingly apparent that these tendencies are deeply rooted in our prehistory. There’s a reason why bananas are the world’s favorite fruit. The resulting fruit, some 440 tons, had to be peeled and sieved in search of any seeds. The answer was to use phytoliths, a technique first experimentally used in the late 1950s and adopted by archaeologists in the 1970s. Yummy, yellow dessert bananas are bred from mutant strains of banana plants that happened to produce fruit without useful seeds. Bananas are the fruit of Musa acuminata. Genetic changes from M. acuminata created by the domestication process include the suppression of seeds and the development of parthenocarpy: the ability of humans to create a new crop without the need for fertilization. What looks like a trunk is actually a pseudostem, formed by leaves wrapping around each other, with new leaves arising from the centre as the plant grows. Seeds, though, are in short supply. Banana domestication began some 7,000 years ago, but researchers are only now piecing together the global journey of the beloved yellow fruit. Modern bananas can’t even grow seeds. By Chris Hunt and Rathnasiri Premathilake / 24 Aug 2018. These bananas are asexually propagated. “I’ll let you guess how many seeds they collected,” says Emile. Have a look at the picture above. The seeds can be rounded or angled and average between 1/8 and 5/8 inches wide. These heroic journeys also occurred on land. History. We are growing food. More than two-thirds of U.S shoppers include them in their regular grocery shopping. Planting Bananas. The different varieties are characterized by wide differences in peel color and thickness, flavor, fruit size, and resistance to disease. Over time, many generations of selection can substantially alter a plant’s genetic makeup. A phytolith chain from a domesticated banana leaf. Rathnasiri Premathilake. ThoughtCo. However, because domesticated bananas are sterile, reproduction has to be vegetative, so cuttings or whole plants must have been carried. Although since bananas have been commercially grown, the plants are sterile, and the seeds … Hirst, K. Kris. We have known for some time that phytoliths of cultivated bananas appear at Kuk Swamp in Papua New Guinea around 6,800 years ago. Domestication generally involves selecting for beneficial traits, such as high yield. This is a permaculture site. The evolution, or plant systematics, of bananas are difficult to study archaeologically, and so the domestication history was unknowable until recently. The first people for whom we have evidence arrived at Fahien Cave perhaps as early as 46,000 years ago and used it for shelter regularly but intermittently thereafter. These bananas are ready to come down. He subsequently began cultivating these sweet bananas. The first bananas may have been cultivated at least 7,000 years ago – and possibly as early as 10,000 years ago – in what is now Papua New Guinea. The problem is worse in the tropical forests, because of the rapid decay of organic matter in the heat and humidity. The earliest well-supported evidence is at Nkang, a site located in southern Cameroon, which contained banana phytoliths dated between 2,750 to 2,100 BP. The sterile domesticated banana is the result of ancient crossbreeding between wild species. Sweet bananas were discovered by Jean Poujot in 1836. Bananas are fast growing, usually putting out one new leaf every week. Cay Leytham-Powell/SAPIENS. Bananas produce vegetative suckers at the base of the plant which can be removed and planted separately. Edible cultivars of banana are "polyploids" having odd/multiple sets of chromosomes. To make up for this, yellow bananas are more developed when it comes to antioxidants. Every season, the plant dies after its fruit is harvested, and the small bulbs (called the suckers) growing out of the plant's underground rhizome (called the corn) are then replanted, and new plants grow. Instead, Swennen must cut open the seed, releasing the tiny embryo into a nutrient bath. https://www.thoughtco.com/banana-history-human-domestication-170069 (accessed February 9, 2021). Bananas are one of the most widely grown, traded, and eaten of all the crops—an essential and much-loved part of the diet for many people around the world. Modern bananas came from two wild varieties, Musa acuminata and Musa balbisiana, which had large, hard seeds, like the ones in this photo. Frequently found in our lunchboxes, breakfast mix and often one of the first foods babies eat, they are a household staple. Bananas (Musa spp) are a tropical crop, and a staple in the wet tropic areas of Africa, the Americas, mainland and island Southeast Asia, South Asia, Melanesia, and the Pacific islands. Bananas produce vegetative suckers at the base of the plant which can be removed and planted separately. Acuminata means long-pointed or tapering, not referring to the fruit, but to the flowers giving birth to the fruit. Nearly nine-tenths of the world’s bananas are eaten in poor countries, where at least 400 million people rely on them for 15-27% of their daily calories. The History and Domestication of Bananas. Although since bananas have been commercially grown, the plants are sterile, and the seeds … Every season, the plant dies after its fruit is harvested, and the small bulbs (called the suckers) growing out of the plant’s underground rhizome (called the corn) are then replanted, and new plants grow. Exploitation of early wild forms of bananas has been noted at the Beli-Lena site of Sri Lanka by c 11,500-13,500 BP, Gua Chwawas in Malaysia by 10,700 BP, and Poyang Lake, China by 11,500 BP. Bananas, too, are parthenocarpic and produce fruit in the absence of successful fertilization. The fungus, which can live undetected in the soil for decades, enters banana plants through their roots and spreads to the water- and nutrient … Bananas, like most fruits, produce and react with an airborne hormone called ethylene that helps to signal the ripening process. A wild breadfruit phytolith. Unfinished bananas – to keep these for a little longer, cover them in plastic wrap/cling film, or a sealed plastic container. These early travelers seem, on several occasions, to have carried food plants with them, especially starchy staple crops. Between 9-14 months after planting, each plant produces some 20-40 kilograms of fruit. We are not talking about keeping plants alive outside their natural growing conditions. As it turns out, bananas are a little too gaseous for their own good. A phytolith chain from a domesticated banana leaf. When this is the case the flower is usually dying and the bananas themselves have plumped out of their young rectangular shape. #SpoonTip: Store your bananas in the fridge to prevent micronutrient loss. “I’ll let you guess how many seeds they collected,” says Emile. Is the Term “People of Color” Acceptable. The seed of a wild banana are noxious and the wild banana is unsuitable to eat as a food item – only to be grown as a dense privacy block or an ornamental landscape tree. Genetics and linguistic studies also help in understanding banana history. Man-made selection is capable of ge… Phytoliths have provided an exciting tool for archaeologists and paleobotanists exploring the origin and history of tropical plants. #SpoonTip: Store your bananas in the fridge to prevent micronutrient loss. Some people won’t even touch a banana with a brown spot, while other people will try anything to get their bananas to ripen quicker. Now, in Fahien Cave in Sri Lanka, in deposits about 6,000 years old, we have discovered phytoliths identical with those from cultivated bananas. More than two-thirds of U.S shoppers include them in their regular grocery shopping. There are differences in the phytoliths between varieties of bananas, but variations between wild and domesticated versions are not as yet definitive, so additional forms of research need to be used to fully understand banana domestication. Finding ancient evidence for soft, sappy plants like bananas is extremely difficult at the best of times. While your bananas will still lose some nutrients, they will lose them at a much slower rate. Try to keep as much of the peel intact as possible to expose the least amount of the flesh to air. Why Do We Keep Using the Word “Caucasian”? Banana phytoliths are uniquely shaped: they are volcaniform, shaped like little volcanoes with a flat crater at the top. Think of carrots, corn or watermelons – all foods you might eat without much consideration. First domesticated over 7000 years ago, bananas have been, over thousands of years, selectively bred to have really tiny non-fertile seeds. These clumps grow into new plants that are genetically identical to their parents. Wild Bananas. It’s an efficient way to grow thousands of plants. Rathnasiri Premathilake. Bananas are planted at a typical density of between 1500-2500 plants per square hectare. Spotted Bananas Sasha Kran Some phytoliths of domesticated bananas are distinctive and therefore give us a tool to chart their appearance in ancient sediments. After the harvest, the plant is cut down, and one sucker is allowed to grow up to produce the next crop. “About fifteen. Most people are used to being able to buy a wide range of produce that domestic farmers would struggle—or find impossible—to grow. Without the genetic modification by selective breeding, bananas would be almost inedible. (2020, August 27). Wild bananas contain big, hard seeds and very little flesh. Hirst, K. Kris. The ancient dispersal of manioc from central South America to Mexico and of maize in the opposite direction has also been suggested. Cross-breeding of two varieties of wild bananas, the Musa Acuminata and the Musa Baalbisiana, in Africa in about 650 AD, resulted in bananas becoming seedless and more like the delicious fruit we enjoy today. Have a look at the picture above. He discovered banana trees in his farm bearing yellow fruit instead of the normal red or green types. Wild bananas contain big, hard seeds and very little flesh. And … Retrieved from https://www.thoughtco.com/banana-history-human-domestication-170069. Between 9-14 months after planting, each plant produces some 20-40 kilograms of fruit. Frequently found in our lunchboxes, breakfast mix and often one of the first foods babies eat, they are a household staple. In contrast, wild bananas are packed full of bullet-like seeds and contain very little edible fruit. Antonius Musa was the personal physician to Roman emperor Octavius Augustus, and it was he who was credited for promoting the cultivation of the unusual African fruit from 63 to 14 B.C. This article was originally published at The Conversation and has been republished under Creative Commons. Today, M. acuminata is found throughout mainland and island southeast Asia including the eastern half of the Indian subcontinent; M. balbisiana is mostly found in mainland Southeast Asia.

The transport of banana plants or cuttings between Papua New Guinea and Sri Lanka would have been fraught with difficulty, as it most likely happened in open canoes—an amazing feat, even if the journey took many voyages over many years. Acuminata means long-pointed or tapering, not referring to the fruit, but to the flowers giving birth to the fruit. See the full NFL conference standings and wild card teams as if the season ended today. The resulting fruit, some 440 tons, had to be peeled and sieved in search of any seeds. https://www.hsph.harvard.edu/nutritionsource/food-features/bananas Wild bananas can be found in the wet, hot forests of New Guinea and South and Southeast Asia, but for many years the origin of domesticated bananas was a complete mystery. But far from hindering their spread, this genetic quirk is what has made bananas such a desirable crop. Hirst, K. Kris. Banana plants are cultivated by removing rhizomes from host plants and replanting the samples to grow on their own. Because Cavendish bananas lack seeds, growers at some large plantations generate new plants from suckers, or the offshoots of adult plants. Archaeological evidence from the Kuk Swamp of the highlands of New Guinea indicates that bananas were deliberately planted by at least as long ago as 5000-4490 BC (6950-6440 cal BP). Some bananas, depending on the species, can have quite a few seeds -- even to the point that the fruit is more seeds than flesh. Yet when compared to their wild ancestors, even the “organic” varieties are almost unrecognisable. In the United Kingdom, one in four pieces of fruit consumed is a banana and, on average, each Briton eats 10 kg of bananas per year; in the United States, that’s 12 kg, or up to 100 bananas. They are cheap to buy, soft and easy to eat and full of fat-free nutrients. Bananas produce vegetative suckers at the base of the plant which can be removed and planted separately. Between 9-14 months after planting, each plant produces some 20-40 kilograms of fruit. The yellow thing you peel and eat is, in fact, a fruit because it contains the seeds of the plant. Culture / Domestication / Food / Migration, An editorially independent magazine of the Wenner‑Gren Foundation for Anthropological ResearchPublished in partnership with the University of Chicago Press. Ripe bananas – once your bananas have reached the desired level of ripeness, you can store bananas in the fridge to stop them from ripening too quickly.. Phytolith evidence tells us that from the beginning they were eating and using a variety of wild plants, including breadfruit, durians, canarium nuts, species of palm and bamboo—and wild bananas. Later finds include those from Munsa, Uganda, 5,250 years ago, and Kot Diji in Pakistan, 4,250 years ago. It is possible that they were then spread into South Asia and Africa from Sri Lanka, or that bananas reached them directly, during the same migration. In 2012, a resident of Illinois managed to break a world record by peeling and consuming 8 whole bananas in 60 seconds. While your bananas will still lose some nutrients, they will lose them at a much slower rate. Banana plants take around nine months to grow up and produce banana tree fruit, and then once the bananas have been harvested, the plant dies. Ethnographic observations suggest uses as diverse as plates, food wrapping, medicines, stimulants, textiles, clothing, packaging, paper-making, crafts, ornaments, and also in ceremonial, magic, and ritual activities. Bananas are basically giant herbs, rather than trees, and there are approximately 50 species in the Musa genus, which includes the edible forms of bananas and plantains. Swennen estimates that he gets only 5 to 20 seeds per bunch of bananas (a bunch can contain anywhere from one to 200 fruits). Kuk Swamp, in Papua New Guinea, so far the earliest unequivocal evidence for banana cultivation, had wild bananas there throughout the Holocene, and banana phytoliths are associated with the earliest human occupations at Kuk Swamp, between ~10,220-9910 cal BP. Cultivating Bananas . Silica is an extremely durable mineral, and silica phytoliths have been shown to survive for millions of years in suitable circumstances. Additional evidence indicates that Musa acuminata ssp banksii F. Muell was dispersed out of New Guinea and introduced into eastern Africa by ~3000 BC (Munsa and Nkang), and into South Asia (the Harappan site of Kot Diji) by 2500 cal BC, and probably earlier. They are cheap to buy, soft and easy to eat and full of fat-free nutrients.
