Early farming created population booms—and also major busts

Imagining the farms of the future

About 10,000 years ago, humans began to farm. This agricultural revolution was a turning point in our history and enabled the existence of civilization. Today, nearly 40 percent of our planet is farmland. Spread all over the world, these lands are the pieces to a global puzzle we're all facing: in the future, how can we feed every member of a growing population a healthy diet? Brent Loken investigates in this seven-minute video.

What happens when the population grows faster than the food supply?

Human history is shaped by our ability to feed ourselves. See how population growth is tied to farmland, and how food production’s profound environmental effect shows us the need for change.

A medieval warm period reshaped agriculture across parts of the world

Between 750 and 1350 CE, some regions experienced temperatures that rivaled or exceeded late-20th-century averages, likely due to shifts in El Niño–La Niña cycles. The warmer, wetter climate in Europe and northeast North America boosted agriculture, while causing droughts elsewhere.

The ancient crops we've forgotten how to grow

Roughly half of all world calories today stem from maize, wheat, and rice. But for most of history, plants were domesticated in highly local places. This video dives into the scientists learning about crops no longer highly in use that once fueled entire civilizations in North America. Some forgotten crops include pitseed goosefoot, maygrass, and sumpweed.

Mapping how human population has grown throughout history

It took 200,000 years for our human population to reach 1 billion—and only 200 years to reach 7 billion. When will our global population peak? And how can we minimize our impact on Earth's resources, even as we approach 11 billion?

Watch the history of human migration that led to civilizations

Feudal landholding organized medieval Europe’s economy without relying on slavery

From the 10th to 13th centuries, Europe’s agricultural system relied on localized hierarchies. Lords granted land to knights for defense, who in turn mainly oversaw free peasants paying rents in labor, goods, or money rather than living under slavery.

Why genetic similarities between humans suggest a past near-extinction event

Researchers have found that low genetic diversity among humans—even those on opposite sides of the planet—may result from a breeding population of as few as 1,280 adults, estimated to have existed 930,000 years ago. This genetic bottleneck may have resulted from a near-extinction or from a small population of human ancestors, from which we all descend, that broke off from a larger population.

See how migrating tribes reshaped Europe after the fall of Rome

During the early Middle Ages (c. 300–700 CE), groups such as the Franks, Vandals, Visigoths, and Suebi migrated into former Roman territories. Their movements transformed European politics and culture while preserving many Roman traditions.

The Archaic period marked Native Americans' shift from big-game hunting to foraging

Beginning around 8000 B.C.E., Indigenous peoples began relying on diverse food sources—including wild game, plants, seeds, and fish—and moved away from large-mammal hunting. Archaeological findings from this era suggest some communities began cultivating crops and establishing irrigation systems, indicating a shift toward less-nomadic lifestyles.

The Middle Ages produced inventions that still affect our lives today, like coffee houses and improved agricultural techniques.

The 1580 influenza pandemic, traced from Asia to Africa and into Europe, became the first flu outbreak clearly documented across the continent—killing tens of thousands and highlighting influenza’s potential for rapid global spread.

The Middle Ages, the roughly 1,000-year period between the fall of Rome and the Renaissance, shaped the political and cultural foundations of modern Europe.

Europeans' arrival to America brought disease to Indigenous populations

Indigenous people lived in the Americas for centuries before the arrival of the first Europeans in the 15th century. Their arrival was disastrous for Native tribes; in addition to being enslaved and losing their land, they had no natural immunity to the diseases brought by colonists. Eventually, up to 95% of the Native American population was killed by illnesses including typhus, chickenpox, and cholera, an event now known as the Great Dying.

The evolution of the human diet

Could eating like our ancestors make us healthier? One estimate suggests prehistoric hunter-gatherer communities obtained 75% of their calories from meat and fish.

Human beekeeping has been traced back to 7000 BCE

Eighty-seven of the world's leading crops rely on pollination in some way, including 43 that are highly dependent or entirely reliant on it. Without pollinators, key foods such as apples, avocados, and almonds would likely become extinct, pushing entire ecosystems into collapse.

The ancient origins of focaccia

Focaccia, the Italian flat oven-baked bread that’s often a canvas for delightful culinary artwork, has been around for thousands of years. Archeologists have recently discovered evidence of flatbreads similar to today’s focaccia dating back to the Late Neolithic period in the Fertile Crescent. Researchers believe that communities from present-day Syria and Turkey made these distinctive loaves for large gatherings. Learn more about the bread’s history in this Archeology News article.

European diseases killed a massive share of the Native American population

After Western contact, epidemic diseases devastated Indigenous communities. By 1920, the Native American population of the US had fallen to roughly 270,000, compared with an estimated 1.2 to 18 million at the time of European arrival.

Global population growth peaked six decades ago, at 2.3%.

Agricultural intensification has accelerated declines in pollinator populations

The practice of using farmland more frequently to increase its yield increases the number of residual pesticides and decreases botanical biodiversity. These processes tend to decrease carrying capacity for pollinators by eliminating food sources and nesting habitats.

Without dinosaurs, plants could produce fleshy fruits with bigger seeds

Previously disturbed by massive herbivores, denser and darker forests shifted plant evolution, reaching the greatest diversity of seed sizes, fruit sizes, and fruit types about 50 million years ago.
