Up until about 10 000 years ago, all human beings were hunter-gatherers. This means that they moved from place to place to find food. 

They would pick it, dig it up, fish for it, hunt and kill it. When they found an new food the only way to find out if it was edible was to just try it.  If it tasted okay and didn't make them sick, everything was well.However, as they risked trying out new foods, they must have sometimes gotten very sick and perhaps even died! 

As humans learned to make food storage vessels and other tools, and learned to cooking and preserve food, they were able carry safe and healthy food with them as they moved from place to place.

Around 10 000 years ago people started to grow some of their food. Some scientists think that the idea for growing food came about because the people noticed that seeds in pieces of fruits and vegetables that they had thrown away began to sprout and grow.
