Many of the foods we eat today began as wild plants.

Over thousands of years, humans selectively bred crops for taste, productivity, and reliability.

Take a look at a tomato. Though it is a staple in kitchens worldwide today, it originated from the Americas and wasn't introduced to the rest of the world until the 16th century.

Its journey is a perfect example of human crop domestication and the global food trade. The produce we rely on isn't purely wild, it is the result of a long history of biological fine-tuning and global exchange.

Modern crops often look very different from their wild ancestors.

Agriculture has always involved shaping biology to meet human needs.
