And so agriculture was created. Mankind set out to do genetic engineering, doing RNA Interference (RNAi) cereals, legumes, roots and tubers. They not only scientifically selected for larger fruits, uniform ripening and taste, they even turned dangerous natural foods into healthy ones. 
Do Drosophila, commonly called fruit flies, have culture?

Culture, lasting changes in a group that cannot be ascribed to genetic or ecological variation, is obviously a human quality, and it may be found in other vertebrates like some other primates and birds. A new computer simulation says it may be in fruit flies also.

Fruit flies can learn and copy the sexual preferences of their conspecifics after observing them copulating. For a behavioral pattern to be deemed culturally transmitted, there are considered:

1) the behavior must be learned socially, which is to say by observing conspecifics,
2) be copied from older individuals,
3) be memorized over the long term,
