This archive covers progress stories from North and Central America, spanning the U.S., Canada, Mexico, and the nations of Central America. Readers will find reporting on health, environment, community resilience, and policy advances across the region.
Maize domestication began about 9,000 years ago in Mexico’s Balsas River valley, where Indigenous growers slowly coaxed a stubby wild grass called teosinte into the tall, seed-packed grain we know today. Genetic studies trace every corn plant alive back to that single origin — one of the most consequential acts of plant breeding in human history.
Classic Maya Belize, around 800 C.E., supported somewhere between 400,000 and one million people across a landscape of stone cities, terraced fields, and astronomical observatories. At Altun Ha, archaeologists recovered one of the finest jade carvings known from the entire Maya world. It’s a reminder of how much a society can build when given fertile land and time.
Fort Rock sandals, twined from sagebrush bark roughly 11,000 years ago in what is now central Oregon, rank among the oldest footwear ever found. Archaeologist Luther Cressman unearthed dozens in 1938, preserved beneath ash from Mt. Mazama’s eruption. They hint at a deep tradition of fiber craft in the ancient Americas, most of which has quietly dissolved into time.
Agriculture in the Americas emerged not once but at least three separate times, with cultivated crops appearing in Mexico and South America as early as 8000 B.C.E. Indigenous farmers domesticated maize, potato, tomato, cacao, and quinoa, and engineered systems like the Three Sisters and Andean terraces. It stands as one of history’s clearest cases of humans independently inventing farming.
The Bering Land Bridge carried the first people into the Americas sometime between 20,000 and 13,000 years ago, across a grassy plain nearly 1,000 miles wide. Genetic evidence traces hundreds of Indigenous nations back to those travelers, who reached the tip of South America within a few thousand years — one of the fastest continental migrations in the human record.
Early humans in Mexico may have gathered around campfires in the Valley of Mexico as far back as 21,000 years ago. From that uncertain beginning, their descendants domesticated maize from a wild grass, built Teotihuacan into a city of 100,000, and independently invented the concept of zero — achievements still shaping the world today.
Bluefish Caves, tucked into a limestone ridge in northern Yukon, hold animal bones with stone-tool cut marks dated to roughly 24,000 years ago. A 2017 reanalysis of horse and mammoth remains confirmed those dates, suggesting people endured the Last Glacial Maximum in Beringia far earlier than the long-dominant Clovis-first timeline allowed.
Arctic migration began roughly 30,000 years ago, when people crossed into a world of months-long darkness, shifting ice, and killing winds. The Thule, ancestors of today’s Inuit, later spread across the high Arctic using kayaks, umiaks, and dog sleds. Their descendants still live there — one of humanity’s longest continuous experiments in adaptation.
