agri culture

 How could a group of humans living off their hunting and gathering ventures, develop the cultivation of land or agriculture and the domestication of animals?

Could it be a pot filled with water with a single leaf placed inside? Forgotten in time, slowly but surely growing roots out of it. And when the human observed the outcome, decided to experiment with the flora around and crucially, cultivate their source of subsistence?

Perhaps it is the fruit's remaining seeds persistently thrown around the group's occupied land when eventually, the newly-grown plants around them produced the same fruit.

Perhaps they had mushrooms visualizing modernity and later, they were just striving to fulfil it...

I do not want to dwell in what constitutes the culture of agriculture but rather on the fact that agriculture implies some sort of culture. Since groups of humans developed some form of agriculture they have also developed a culture around agriculture. 

In other words, a culture can be observed and verified from the daily lives of the group at hand. Without the regular hardships of maintaining land and animals, agriculture wouldn't have developed. A day off can be fatal for the whole group. Thus, the alteration of the humans' daily lives to manifest the agri culture shows clearly how a culture can be established.

Whether in a social group or not, the actualisation of the cultural traits we wish to flourish lie on the individual. Of course, the manifestation or creation of a culture is better done with others but that doesn't hinder the responsibility of each one.
