Fruit has always been selectively bred. It's a bribe to animals.

My experience is that supermarket varieties of fruits are bigger and look better than local, traditional produce, or are more practical in other ways (thinner skin, less or no seeds) but are often insipid in comparison.

On the other hand (and this is just speculation), in the northern hemisphere most fruit is naturally available in the fall season. Fattening prior to winter was probably a desirable effect.
