Habits Die Very Hard
This is really surprising but it's a fact that all ants were human-beings to begin with. They lived by tilling soil and raising crops just as farmers do even today.
Dissatisfied with what they used to get through their labour, these farmers always had their eyes on the crops of their neighbours. Not only this, they even used to steal their crops whenever they got a chance and adding on to their own store.
The gods got highly offended by these acts and went to their chief- Jupiter to complain against the thieving farmers. He got so angry that he converted these farmers into ants.
Though the form of these farmers got changed, their habit of stealing is the same till today. The ants go about the corn-fields and gather grains not belonging to them.
This shows that one's nature seldom changes.
