Firstly, peas and fruit flies come to maturity much faster than humans so you can fit in lots of generations in a practicable time. Secondly, fruit flies have a much simpler genotype than we do. Finally there are far fewer ethical restrictions when you experiment on flies or peas.
Flies breed a lot faster, so a single researcher can watch the influence over several generations, which really wouldn't be possible on humans. Also, the flies can be kept in an almost entirely controlled environment, making it easier to exclude external factors from causing one or the other.
