Fruit Flies vs. Humans?
According to journalists covering neuroscience research, such research has proved that humans don't have free will (actual article here and there and my discussion here) but fruit flies do (actual article here).
I have no reason to believe either experiment was performed by fruit flies, although the fruit flies might have done a better job. I have never seen an allegedly-scientific article by fruit flies drawing far-reaching conclusions from a sample size of 14.
