How did early humans learn agriculture?

It is impossible to determine the exact origin of agriculture and the point in time in which it was first invented because agriculture existed before writing. Humans transitioned from a hunter-gatherer societies to more domestic societies that farmed about 10,000 years ago. Archealogists argue how quickly agriculture was adopted, and how gradual the process was to learn. They probably learned through trial and error, and by watching nature and its climate patterns.
