Agriculture
147 inventions in this category
Agriculture inventions solve the carrying capacity problem—enabling land to support more people than hunting and gathering ever could. The Neolithic Revolution (starting ~10,000 BCE) was humanity's first great technological transition: irrigation, plows, and selective breeding transformed nomadic bands into settled civilizations. Each subsequent breakthrough—the steel plow (1837), mechanical reaper (1830s), center-pivot irrigation, synthetic fertilizers—multiplied yields. These inventions exhibit strong niche construction: irrigation created farmland that created demand for harvesting tools that created demand for storage that created demand for transportation. They demonstrate coevolution: crops and farmers shaped each other over millennia. The biological parallel is ant agriculture—leafcutter ants cultivate fungus farms, demonstrating that humans weren't the first species to invent farming. By the 1950s, tractors outnumbered draft animals on American farms.
