You wrote: bees were altered in size (bigger) by mechanical means (using different cell sizes), with genetics, and possibly fed artificial feeds (Sugar syrups and pollen substitutes) So far as I know, nobody has ever proven that this has taken place anywhere. Sure, workers can be somewhat enlarged just as tiny drones can be raised in worker comb. But would be for that one generation only. Environmental effects cannot be directly inherited.
